Odontoma is a benign calcifying odontogenic tumor of unknown etiology, although local trauma, genetic factors, and chronic inflammation may be related. They are classified into compound and complex types, depending on the morphological, radiographic and histological characteristics. Clinically they hardly show signs or symptoms, and, when present, are related to delayed tooth eruption, cortical bone expansion and tooth displacement. Although radiographic exams are complementary, most cases of odontomas reported in the literature are found on routine radiographs. The diagnostic hypothesis is confirmed by histopathological examination that shows evidence of the presence of enamel, dentin, cementum and pulp tissue arranged in the form of denticles (compound) or a disorganized mass (complex). The treatment consists of surgical excision of the lesion. The aim of this article was to report a clinical case and histopathological analysis of a complex odontoma associated with an unerupted tooth, located on the left side in the posterior region of the maxilla, discovered by routine radiographic examination of a 57-year-old male patient. The treatment was surgical excision of the lesion, removal of the unerupted tooth and histopathological examination, which confirmed the diagnosis of complex odontoma. The case was followed-up clinically and radiographically for one year and showed no recurrence.

Odontomas are the most common odontogenic tumors. They are broadly classified in to Compound Odontoma and Complex Odontoma. Among them complex odontoma is a rare tumor. Occasionally this tumor becomes large, causing expansion of bone followed by facial asymmetry. Otherwise these tumors are asymptomatic and are generally diagnosed on radiographic examination. We report a rare case of complex odontoma of mandible in a young boy. The tumor was treated by surgical excision under general anesthesia.

Substances considered foreign to the human organism can penetrate it due to local trauma, initially causing an acute inflammatory response against these substances, involving a neutrophilic infiltrate that, when it fails to deal with these foreign bodies, ends up generating a granulomatous inflammatory response. Granuloma formation has been associated with a variety of conditions. The correct clinical and imaging diagnoses are extremely important for the dentist to choose an appropriate therapeutic approach, aiming at the best possible treatment. This work is aimed at describing a case report of a foreign body granuloma, formed on the tongue, from the penetration of a pequi spine, in a 76-year-old patient, in whom, after an imaging diagnosis with ultrasound, surgical removal of the lesion was performed, and the piece was sent for histopathological examination, which confirmed the initial diagnostic hypothesis of a foreign body granuloma. The initial diagnosis of foreign body granulomas is challenging. For this reason, more sophisticated means of diagnosis such as tomography and magnetic resonance become important in the diagnosis, as they can show with greater clarity and reliability the nature of the lesion and its relationship with adjacent anatomical structures. In the case in question, an ultrasound examination was chosen, which was extremely important as an aid to diagnosis, considerably improving surgical planning. In addition, after surgical removal, the result of the histopathological analysis is essential to determine the definitive diagnosis, as it determines the granulomatous characteristic of the lesion.

Introduction. Osteomas are a slow growing benign neoplasm of unknown etiology very rarely involving the temporal bone. They develop in the external auditory canal on squamous sections, in the mastoid, middle and inner ear. By bone composition they are divided into spongious (osteoma spongiosum) and compact osteomas (osteoma eburnum); by growth direction, into outward-growing (exosteoma) and in inwardgrowing (endosteoma); into unilateral and bilateral; by size, into small and gigantic; by surface structure, into smooth and multilobular; by number, into solitary and multiple; into symmetrical and asymmetrical. The symptoms of intracanalicular osteomas are the result of auditory canal obstruction. Diagnosis is made based on case history, clinical examination, audiological processing and radiography (temporal bone CT scan), and confirmed by histopathological examination of the bone. In terms of differential diagnosis, they must be distinguished from exostoses, bone tissue proliferation and osteoid osteomata. The progress of the disease is prolonged, as they are slow growing, asymptomatic and benign tumours. Therapy is surgical only. Case Outline. The report presents the case of a 70-year old patient with the osteoma of the right external auditory canal. In our patient, the osteoma arose in the auditory canal, the most frequent localization; it was unilateral, solitary, multilobular and compact. It was discovered accidentally, during otoscopic examination. The clinical diagnosis was confirmed by CT scan of the temporal bone. We applied surgical therapy by retroauricular approach. The removed bone change was about 12 mm high, 13-14 mm deep and about 8 mm wide. Histopathological findings confirmed osteoma. Conclusion. Due to their slow growth, the rate of auditory canal osteomas develop asymptomatically for a long time without the characteristic clinical features. In most cases, they are discovered accidentally during otoscopic or radiographic examination. The method of choice in diagnosis is temporal bone CT scan. Therapy is surgical.

Background: Myxosarcoma is a malignant mesenchymal tumor that arises from fibroblasts and is characterized by a low frequency of metastases, which in turn are highly invasive locally. Even though this type of tumor is relatively well documented, its radiographic and cytomorphological aspects are rarely described. The present report describes a case of cutaneous myxosarcoma in a female dog, and highlights radiographic, cytological, and histopathological findings.Case: An 11-year-old female mongrel dog was examined at the Veterinary Hospital of Federal University of Paraíba. The patient exhibited a firm 20 cm-wide mass covered by skin in the left abdominal wall, a lesion that had been developing for approximately five months. During the clinical examination, the patient demonstrated apathy and difficulty to stand. Initially, exams requested included radiography, ultrasonography, and cytological analysis of biopsy material obtained by fine needle aspiration (FNA). Radiography and ultrasonography were used to investigate the extent of the tumor, as well as invasion of other organs. Radiography revealed that the tumor was radiopaque, homogeneous, and restricted to the skin and subcutaneous tissue; no metastases were observed.  Cytological examination allowed observation of a hypocellular sample predominantly composed of isolated pleomorphic fusiform cells embedded in a discrete homogeneous eosinophilic material. These cells exhibited a moderate, well delimited cytoplasm with multiple vacuoles; the end opposed to the nucleus was slender.  Their nuclei were eccentric, with punctate chromatin and inconspicuous nucleoli.  The patient was subjected to complete surgical excision of the tumor, and the surgical piece was submitted to histopathological examination. The mass was described as single and firm; its dimensions were 20 cm x 16 cm x 15 cm, and its weight was 2.5 kg.  Fragments were processed and stained with hematoxylin and eosin (HE) or alcian blue (AB) for evaluation by optical microscopy. Histopathology revealed an infiltrative, expansive, non-encapsulated mass characterized by mesenchymal cells ranging from elongated to stellate. These cells were well individualized, had a scant to moderate cytoplasm, indistinct and slightly eosinophilic borders, and a nucleus that varied from oval to stellate in shape, with highly condensed chromatin and inconspicuous nucleoli. AB-stained specimens exhibited an extensive myxomatous matrix stained in blue, which was intertwined with neoplastic cells. Therefore, the diagnosis of cutaneous myxosarcoma was confirmed.Discussion: The diagnosis of myxosarcoma was established on the basis of radiographic and cytological findings, and it was confirmed by histopathological examination, which sped up decision-making and completion of the case.  Tumors of this group are not accompanied by paraneoplastic syndromes; however, given the size and weight of the mass under study, pain may have been the triggering factor of the apathy and difficulty to stand observed here. The age of the patient and the occurrence of the tumor in the skin are in agreement with the literature; however, presence of the tumor in the abdominal skin is uncommon, and this fact prevented definition of a clinical suspicion prior to cytopathological examination. Radiographic examination confirmed the dimensions and extent of the mass; additionally, it allowed exclusion of occurrence of metastatic foci. Cytologically, the material analyzed was consistent with literature findings for canine myxosarcoma samples, so that cytopathological examination already suggested occurrence of such condition in this case. Histopathological evaluation was indispensable for establishment of the diagnosis as well as AB staining, which highlighted high amounts of glycosaminoglycans among the neoplastic cells, which led to confirmation of the diagnosis.

SummaryThree four-month-old female grey-hound siblings with osteochondral fragmentation of the lateral aspect of the patella are presented. One dog was affected unilaterally and two bilaterally. The dogs exhibited mild weight-bearing lameness, slight flexion of the stifle, and discomfort during full flexion and extension of affected stifles. A non-palpable, mild synovial effusion was cytologically consistent with chronic inflammation and compatible with osteochondrosis and degenerative joint disease. The hallmark clinical sign was a characteristic prominence of the patella. Cranioproximalcraniodistal oblique (skyline) radio-graphs and transverse CT scans revealed osteochondral fragments and defects of the patella. The osteochondral fragments were surgically excised in two dogs and one dog was necropsied. The osteochondral fragments and patellae were evaluated histologically. Macroscopic and microscopic features of the osteochondral tissues were characteristic of osteochondrosis.Osteochondrosis of the patella was diagnosed in three sibling Greyhounds. The hallmark clinical sign was enlargement and prominence of the patella. Radiographic examination, cranioproximal-craniodistal oblique view, demonstrated the fragmented lateral border of the patella. Findings from computed tomography and histopathological examination are described. Surgical excision of the fragment in two dogs restored satisfactory function.

Background: Limbal melanoma has been diagnosed in dogs and due to progression may cause vision loss and eyeball removal. Definitive diagnosis is made through histopathological examination. Therapeutic options include full thickness resection and repair by homologous corneal tissue, synthetic graft material, and enucleation. In this report, we describe a case of limbal melanocitoma in a dog that has been treated successfully with fresh homologous corneoscleral graft.Case: A 5-year-old female Labrador was referred to the Ophthalmology Veterinary Section of the Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, Brazil, with a history of a pigmented mass located on the left eye. Ophthalmic examination revealed a pigmented mass located at the left temporal limbus with corneal involvement. Surgical excision followed by reconstruction using fresh homologous corneoscleral was recommended. The patient was premedicated with acepromazine (0.05 mg/kg, IM) and meperidine (20 mg/kg, IM). Anaesthesia was induced with propofol (10 mg/kg, IV) and maintained with isoflurane. Atracurium (0.2 mg/kg, IV) was administered to maintain a central eye position. The mass and a free margin were removed by full-thickness corneoscleral resection. A corneoscleral graft was harvested from a dogthat had been euthanised for reasons unrelated to this study and sutured with 9-0 polyglactin 910 using a simple interrupted pattern. The mass was immediately fixed in 10% neutral buffered formalin and submitted for histological sectioning and routine staining. Based on the histopathological analysis it was confirmed limbal melanocytoma. Postoperative treatment consisted of topical administration of 0.3% flurbiprofen every 6 h for 15 days, and a combination of topical ciprofloxacin/dexamethasone eye drops every 6 h for 30 days. Systemic carprofen (4 mg/kg per day, VO) was prescribed for 10 days. Topical tropicamide was used twice daily for 1 week. Cyclosporin 0.2% eye drops were applied twice daily for 2 months. Examination of the left eye two months after surgery revealed decreased corneal vascularization, and the results of pupillary light response and vision testing were normal. The values of intraocular pressure remained normal in all postoperativeevaluations. The patient was followed for 36 months postoperatively, during which time there was no recurrence.Discussion: Limbal melanomas are the most common ocular melanomas in dogs. Most of them develop slowly and are located closely to the superior limbus. The tumors tend to grow more rapidly in younger dogs and more slowly in older dogs. Labrador Retrievers and German shepherds appear to be affected more frequently than other breeds. The present case involved a 5-year-old Labrador breed. The clinical presentation included a pigmented limbal mass extending intothe adjacent cornea, sclera and conjunctival tissue. A tissue biopsy is necessary to confirm the diagnosis. In the present case, the diagnosis of limbal melanocytoma was based on clinical signs and confirmed by histopathological examination. The choice of treatment is influenced by the tumour size and location, availability of equipment and materials, clinician expertise and the cost of treatment. Some techniques for removing the mass and repairing the resultant corneoscleral defect has been described. In the present case, due to the location and size of the mass and the absence of intraocular invasion, surgical removal including a margin of normal tissue was performed. With this surgical procedure, the intention was to preserve the eyeball and maintain vision. In this case, surgical excision of a limbal melanocytoma combined with homologous corneoscleral graft was effective for repairing a full-thickness corneoscleral defect and preserving ocular function.

ABSTRACT Mucocele is a benign lesion, originating from disorders of minor salivary glands containing mucus. These lesions are found in children and young adults and usually occur due to local trauma. Clinically, it presents as a circumscribed, asymptomatic, soft and bluish or normocromic blister. The treatment of choice is surgical removal, when the lesion does not rupture naturally. This study aims to report a clinical case of mucocele in a pediatric patient removed through total surgical excision. A 7-year-old patient accompanied by mother sought care at the Dentistry Clinic of the “Tiradentes” University Center (UNIT / AL), with a main complaint of asymptomatic blister in the lower lip for about 15 days. In the anamnesis, the habit of biting in the region was reported. At clinical examination, a blister with clear limits of approximately 10 mm in diameter was observed in the lower lip mucosa, with slightly firm/fibrous consistency, which gave rise to doubts about the possible diagnosis, since it presented characteristics similar to that of a mucocele, although consistency at palpation indicates possible fibroma. Surgical excision of the lesion was performed; the material collected was fixed in 10% formalin and sent to histopathological examination that confirmed the diagnosis of mucocele. The patient was kept on follow-up, and there was no recurrence of the lesion. Surgical excision demonstrated an effective and prognostic therapeutic course, allowing accurate diagnosis through the histopathological evaluation of the lesion.

Introduction: Kimura disease is a rare chronic inflammatory disorder affecting the subcutaneous tissue. It is of unknown etiology mainly occurring in head and neck region. Case report: A 34-year-old Malay lady presented with a gradually enlarging, painless right nasal bridge mass for one year duration. Clinical examination revealed a firm, immobile swelling measuring 2 cm x 2 cm. Nasal endoscopy showed no extension of the mass into the right nasal cavity. Surgical excision was performed where histopathological examination reported as finding consistent with Kimura disease. Conclusion: Kimura disease is extremely a rare benign disease, which can affect the head and neck structures. Manifestation at the nasal region is an extremely rare occurrence. Histopathological examination is needed to diagnose the disease.

Dentigerous cysts are the most common developmental odontogenic jaw cysts, associated with crowns of an Unerupted tooth. Usually, they occur in the second and third decade of life with a male predilection. They are frequently asymptomatic and mostly discovered incidentally on routine dental radiographic examination. Its growth is slow, and can reach a considerable size causing bone expansion and displacement of teeth. Mandibular lower third molars are the most frequently effected teeth; dentigerous cysts involving impacted mandibular canines are rarely reported. Surgical enucleation with extraction of the associated tooth is the standard treatment for dentigerous cyst, marsupialization is recommended for large lesions. We report a rare case of a large dentigerous cyst in a 62-year-old male patient, associated with impacted left mandibular canine, extending from the retro-molar area of left side crossing the midline to the 2nd premolar in the other side, that was successfully treated by marsupialization followed by enucleation and removal of the impacted tooth.

The first drug discovered to be involved in the development of gingival hyperplasia is phenytoin, which is indicated in the treatment of epileptic patients. The other drugs are calcium channel blockers with vasodilating effect. The most important one is Nifedipine, while Ciclosporin A, which is used as an immunosuppressant in the prevention of transplant rejection, causes gingival hyperplasia as a secondary effect. Gingival hyperplasia can reach an impressive volume, completely covering the dental crown and affecting the masticatory and physiognomic functions. The elucidation of the mechanism, by which drug-induced gingival hyperplasia occurs, favoring factors and the choice of conservative or surgical treatment methods, emphasizing the prophylactic treatment. The study batch was subject to intraoral and extraoral clinical examinations and the data were included in the dental treatment sheet of each patient, 11 patients aged over 60 years, who came to the Clinic ... in the period 2014-2016. The diagnosis was based on the anamnesis, the clinical aspect of the lesions and the histopathological examination. After the surgical excision of the hyperplasia affected area, recurrence was prevented by dispensarizing the patients and controlling the bacterial plaque through rigorous oral hygiene. Treatment depends on the severity of the lesions, as well as on the physionomic and masticatory functions. Conservative etiological therapy is attempted, by removing the bacterial plaque and local irritant factors, by reducing the dose of drugs, or by changing the systemic medication.
