Neural Origin

Neurofibromas are uncommon benign tumors in the oral cavity, which are composed of Schwann cells, perineural-like cells, and fibroblasts. The diagnosis can be confirmed by histological examination and immunopositivity for the S-100 protein indicating its neural origin. Surgical excision is the treatment of choice, and the intraoral approach is the best route for a medium-sized lesion and the prognosis is excellent. This paper aims at to present a unusual case of large neurofibroma located at the cheek mucosa of a young man and review important aspects of this tumor in the oral cavity.

Diagnostic Approaches

Accurate diagnostic approaches to differentiate peripheral nerve sheet tumours from others have not been firmly established. The aim of this case report was to diagnose neurofibroma using a combination of diagnostic imaging, histopathology and immunohistochemistry, which were applied to a canine neurofibroma arising in the left mandible. The tumour was surgically excised and examined histologically. Round or spindle cells, with elongated, dense and homogenous chromatin and pale cytoplasm typical of Schwann cells in an abundant fibromyxomatous stroma, with ruby collagen fibres were seen. Immunohistochemistry demonstrated that S-100 and vimentin were more than 70% positive. Neurofibroma may therefore be recognisable using markers such as S-100 and vimentin.

The incidence of auricularSchwannoma is rare. The most common is vestibular Schwannoma. Treatment of choice is completesurgical excision, and recurrence is rare. Purpose: Reporting a rase case of an auricular Schwannomathat spread to external auditory canals. Case: A three years old boy presented with a swelling in the leftauricular for 6 months, which was progressively increasing and spread into external auditory canals.An excisional biopsy via postauricular was performed under general anesthesia. The mass was totallyremoved. Diagnosis was reported to be Schwannoma by histopathologic examination. There was no signsof local recurrence during a 6 months of follow-up period.

Unusual Case Report

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.

Benign tumors of the tonsils occur infrequently. Lymphangiomas are rare congenital tumors of the lymphatic system, and tonsillar lymphangioma is an extremely rare occurrence. Its pathogenesis is uncertain, but history, clinical examination, and histological examination should establish the diagnosis. We present a 17-year-old white male with lymphangioma of the right tonsil. The tonsils were excised and biopsy confirmed the diagnosis. Tonsillar lymphangioma is a rare clinical entity, which should be known to the otolaryngologist, in order to diagnose and treat it appropriately and avoid confusion with tonsillar malignancies.

AbstractBackground:Dermoid cysts in the floor of the mouth are relatively uncommon developmental lesions. They are thought to arise in the midline and along the lines of embryonic fusion of the facial processes containing ectodermal tissue.Case report:A 17-year-old female presented with a 3-month history of a growing, progressive swelling in the mouth floor. Clinical examination revealed a rather large symmetrical, soft swelling in the mouth floor, displacing the tongue superiorly. The fast growing nature and size of the lesion raised suspicion of potential compromise to the airway. Surgical excision was therefore performed.Conclusion:Differential diagnosis of cystic lesions in the floor of the mouth is of paramount importance, as the recommended surgical techniques vary depending on the anatomical position of the lesions. The intraoral approach is preferred for those lesions that do not extend beyond the mylohyoid muscle boundaries; this leads to a satisfactory cosmetic and functional outcome.

Epidermoid cysts are a rare entity in the oral cavity and are even less frequent in the floor of the mouth, representing less than 0.01% of all the cases. We present the case of a 3-year-old girl with a growth in the floor of the mouth with 2 months of evolution and without changes since it was discovered by her parents. The lesion was asymptomatic; it did not cause dysphagia, dyspnea, or any other alteration. A CT scan with contrast was done which revealed the location and exact size of the lesion, allowing an intraoral approach for its excision. The histological examination confirmed the clinical speculation of an epidermoid cyst.

Familial progressive hyperpigmentation (FPH) is a rare genodermatosis characterized by hyperpigmented patches in the skin and mucous membranes, present in early infancy, and increase in size and number with age. The genetic basis for FPH remains unknown. We report an unusual case of familial progressive hypermelanosis in a 17-year-old male patient with family history, who presented with a peculiar progressive oral pigmentation disorder. Diagnosis was confirmed by a series of hematological, biochemical, and histopathological investigations. Our paper stresses the need for the dentist to be aware of the systemic conditions that can also manifest in the oral cavity.

Mucoceles arising from the Blandin Nuhn glands are uncommon benign lesions of the oral cavity, which by their clinical presentation may be confused with more serious diseases such as vascular lesions, pyogenic granulomas, polyps, or squamous papillomas; thereby, it is convenient to be aware of the characteristics of this entity to guide the accurate and timely diagnosis and treatment. Herein, we present a case of a 10-year-old patient with a recurrent lesion of this type, which required surgical excision and marsupialization of the same, with no evidence of recurrence during follow-up.

<p class="abstract">An odontogenic myxoma is a benign odontogenic tumor with locally aggressive behavior. It is relatively rare in the oral cavity. The diagnosis poses a challenge because its features overlap with those of other benign and malignant neoplasms. We present an unusual case of odontogenic myxoma with involvement of the maxilla extending to the maxillary sinus in a 17-year-old lady. A unique computed tomography (CT) appearance revealed a well circumscribed lytic lesion arising from the left maxilla causing expansion and thinning of the maxillary cortex. There is a discernible tooth with adjacent amorphous calcification in a round formation noted within the lesion. Biopsy revealed an odontogenic myxoma. The patient however did not undergo surgical excision as was not consented at the time of this write ups. This paper highlights the unique radiographic appearance of the pathology that has not been reported so far as well as to discuss its clinical significance.  </p>

An unusual case of a newborn with two immature natal maxillary molars is presented. Clinical and histological examination showed that the teeth were rootless and incompletely mineralized. The patient was followed up during one year and we confirmed that the natal teeth were from normal primary series.
