Desmoplastic ameloblastoma (DA) is one of the 6 histopathological subtypes of ameloblastoma. Hybrid lesions in which histopathologically conventional ameloblastoma coexists with areas of DA are rare. A 40-year-old male was referred to our hospital complaining of a swelling in the right premolar region of the mandible. A panoramic radiograph showed an area of radiolucency with a well-defined corticated border, whereas computed tomography revealed a unilocular radiolucent lesion and buccal expansion together with cortical perforation. The lesion was treated via enucleation and curettage of the marginal bone and fenestration. A histopathological examination showed a hybrid ameloblastoma with a pronounced desmoplastic pattern and follicular changes. The patient’s postoperative course has been favorable up to now, and no marked changes have been observed. We presented a case of hybrid ameloblastoma and reviewed the 36 reported cases of hybrid ameloblastoma that have been reported in the English literature.

Spontaneous pneumothorax is rarely reported in the cat. This case report describes the use of computed tomography (CT) to diagnose pulmonary bullae in an adult cat with recurrent spontaneous pneumothorax. A large bulla in the right middle lung lobe and several blebs in other lobes were identified by CT. Partial lobectomy of the right middle and right and left cranial lung lobes was successfully performed to remove the affected portions of lung. Histopathological examination suggested bronchopulmonary dysplasia (BPD) as the underlying cause for development of the pulmonary bulla. This is the first case report in the veterinary literature describing the use of CT to identify pulmonary bullae in the cat with BPD as a possible underlying cause.

Sarcomatous carcinomas (SCs) are rare tumours that contain malignant cells with epithelial and mesenchymal characteristics. SC rarely presents in the head and neck, and occurs even less often in the orbit. Only 8 cases of SCs located in the orbit or affecting the globe function have been described in the English literature. Here, we report a case of SC affecting the right orbit. SC is associated with a poor prognosis and advanced disease at presentation. Diagnosis is difficult, as histology often fails to definitively identify SC, necessitating a wide panel of molecular/immunological markers. Treatment options are generally aggressive but risky, and frequently yield poor results. Due to the rarity of SC, there has been little focus on the development of improved treatment options.

Objectives: This purpose of this  case report is to explain the imaging characteristics of unilocular ameloblastoma in CBCT 3D radiograph. Case Report: A 32-year-old male patient came to the dentist complaining his painful right lower jaw over the past few days. Clinical examination showed extensive swelling in the posterior region of the right mandible to cause asymmetry at the inferior border of the mandibular corpus. Panoramic radiography showed radiolucent area in periapical mesial root of 46 tooth, extending to the right angular mandibular with a clearly demarcated shape,  and there was a root resorption of 47 tooth. CBCT 3D examination showed the presence of unilocular radiolucent lesion in a regular shape and a clear borderline, extending to the inferior border of the mandible and causing buccal-lingual cortical perforation accompanied with the resorption of adjacent 47 tooth. Conclusion: CBCT is a supporting radiography that may act as a more accurate diagnostic tool for the diagnosis of unique ameloblastoma lesions.

SUMMARY The paranasal sinus mucocele is an epithelized cystic lesion containing fluid and is characterized by non-neoplastic expansion of the paranasal sinus due to its capacity to erode the overlying bone. Etiology of these lesions is still under debate. In this report, we described a case of a patient with frontal recess mucocele, associated with contralateral frontal recess osteoma. A 55-year-old man was admitted to the Department of Otorhinolaryngology of our hospital with the complaints of a headache affecting the fronto-ethmoidal region, left-sided nasal obstruction, and postnasal discharge. Computed tomography (CT) scan of the paranasal sinuses showed a dense bony lesion in the left and a cystic hypodense mass in the right-sided frontal recess. The patient was treated surgically, with a combined endoscopicexternal approach, bilaterally. Histopathological examination showed that the wall of the cyst was mucocele, and the bony formation was osteoma. The frontal recess osteoma is regarded as the primary condition. Thus, better ventilation and drainage of the frontal sinus were reestablished.

Abstract Objective Orthokeratinized odontogenic cyst is a rare developmental odontogenic cyst of the jaws. It is a less aggressive intraosseous cyst identified by an orthokeratinized epithelium. Case Report A 50-year-old male patient with the chief complaint of swelling in the anterior part of his face, and, intraorally, there was diffuse swelling in the palatal cortex. On panoramic radiography, there was a well-defined unilocular radiolucency on the right side of the maxilla and palatal cortical expansion, and thinning of the buccal and palatal cortexes was observed. The histopathological examination revealed a pathologic cyst that was lined by a thick orthokeratinized epithelium. Therefore, the diagnosis was orthokeratinized odontogenic cyst. Conclusion The orthokeratinized odontogenic cyst displays characteristic clinical, histopathological, and biological features that differ significantly from those of keratocystic odontogenic tumor (KCOT), but it has a better prognosis and lower recurrence rate. Thus, other radiolucent lesions of the jaws, including keratocystic odontogenic tumor (KCOT), must be considered in the differential diagnosis.

Objectives: The purpose of this case report is to analyze the incidental finding of an odontogenic keratocyst on cone beam computed tomography (CBCT) examination for the case of an impacted tooth 48. Case Report: A 48-year-old man came with a consul letter to perform a CBCT examination with complaints of loose teeth on the right posterior mandible starting from the premolars. Coincidentally found on a sagittal view showed a wide radiolucency lesion on the internal part of the jaw and not related to the impacted tooth. The treatment plan is to remove the lesion and perform a biopsy and perform postoperative panoramic radiograph. Conclusion: The characteristics of the odontogenic keratocyst lesion can be visualized clearly on CBCT. The use of CBCT in analyzing the type and size of the lesion is very helpful in planning surgical treatment. Odontogenic keratocysts can be well-diagnosed using a combination of CBCT examination with histopathological examination to determine the most effective management and prevent a recurrence.

Intraparenchymal epididymal cysts (IECs) are benign cystic formations of the epididymis of unknown pathogenesis, which typically appear in adolescence or adulthood. In patients older than 14 years old their prevalence is doubled. After systematic and thorough research of the current literature, we did not find another case report of intraparenchymal epididymal cyst with similar dimensions. The male patient, 15 years old, visited our outpatient department complaining of pain in the right hemiscrotum. Diagnosis of IEC was confirmed after the conduction of ultrasound examination. Patient underwent surgical exploration of the right hemiscrotum. Resection of the IEC followed. Postoperative course was uneventful, with recession of the symptoms. In our opinion, IECs should be surgically removed, either when they are symptomatic or when they are asymptomatic, but of a diameter greater than 1 cm and without regression tendency.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

Cardiac calcified amorphous tumors are rare non-neoplastic intracavitary masses with unknown cause. A 60-year-old man presented with sustained ventricular tachycardia. Transthoracic echocardiography and contrast-enhanced angio-computed tomography demonstrated an expanding 73 × 40 mm sized calcified mass in the left ventricle. He underwent successful total removal of the mass and cryo-ablation at the normal myocardial border. Histopathological examination confirmed a diagnosis of cardiac calcified amorphous tumors. The postoperative course was uneventful, without ventricular tachycardia recurrence. To our knowledge, this is the first reported case of confirmed cardiac calcified amorphous tumors causing ventricular tachycardia and treated by surgical resection combined with cryo-ablation.

We describe a case of Urrets-Zavalia syndrome (UZS) in a healthy 56-year-old woman who underwent femtosecond-assisted phacoemulsification with intraocular lens implantation in both eyes. One month after an uneventful postoperative course in the left eye, the right eye was operated. Dilated pupil which was nonreactive to light appeared on day 21 postoperatively. This was discovered upon examination following anterior chamber inflammatory reaction which occurred 2 weeks following her surgery. Our case report emphasizes the importance and danger in developing UZS even if the reaction in the anterior chamber does not occur immediately after surgery. In addition, the importance of intraocular pressure follow-up in the period after UZS is acknowledged.
