Juvenile ossifying fibroma (JOF) is a benign, bone-forming neoplasm occurring primarily in children and adolescents. JOF is an aggressive variant of ossifying fibroma of the jaw with a variable clinical behavior and a high tendency for recurrence. Early detection and prompt treatment are required to treat JOF successfully. This case report describes JOF in a 13-year-old girl presenting with a y...

Perivascular epithelioid cell tumor (PEC-oma) is a rare mesenchymal neoplasm. Literature reports more than 100 cases of PEC-oma, a third of which is of uterine or uterine retroperitoneum origin. The case of a 59-year-old woman presented here is, to the best of our knowledge, the first described fast uterine PEC-oma recurrence of the tumor of the gastrointestinal tract origin. In this text the a...

We report a case of a supratentorial primitive neuroectodermal tumor (PNET) that occurred 12 years after cranial irradiation for a grade II astrocytoma. Neuroimaging was unable to distinguish between a recurrence of the original neoplasm and the development of a new, distinct entity. Pathologic review assisted by immunohistochemical staining, however, revealed a high-grade PNET. Although rare, ...

Lymphoepithelioma-like carcinoma of the skin (LELCS) is a rare cutaneous neoplasm with microscopic similarities to non-cutaneous lymphoepitheliomatous malignancies, particularly undifferentiated carcinoma of the nasopharynx. It can be clinically and histologically confused with other benign and malignant tumors. If not adequately treated, recurrence and distant metastasis are probable. We prese...

Melanotic neuro-ectodermal tumor of infancy is very rare. A unique neoplasm of the formative years, it typically involves the face or cranium; possesses rapid, expansile growth; presents as a firm swelling and displays a high rate of recurrence. Its rarity and unique features make diagnosis and management quite challenging. This challenge is increased in resource-limited settings like ours and ...

Eccrine spiradenoma is a benign tumor of sweat gland origin. Malignant eccrine spiradenoma is a rare neoplasm which almost always arises from a pre-existing spiradenoma lesion. In this article, we present a patient with malignant eccrine spiradenoma of the auricula with a prior diagnosis as benign eccrine spiradenoma. Although malignant transformation is usually associated with aggressive behav...

BACKGROUND Ameloblastoma is a benign odontogenic tumour that may exhibit aggressive biological behaviour with local recurrence and metastasis following initial surgical resection. Surgery is the most acceptable modality of treatment, even if a biological approach is currently on study. We report a case of maxillary ameloblastoma with development of neck and brain metastases after repeated local...

Rhabdoid meningioma is a rare aggressive variant of meningioma, regarded as WHO Grade III type. Histologically and cytologically, it is distinctive type having abundant eosinophilic cytoplasm, cytoplasmic inclusion with eccentrically placed vesicular nuclei and prominent nucleoli. High recurrence rate and poor outcome are important features. Here, we are presenting a rare case of rhabdoid menin...

Myoepithelioma is a rare, benign salivary neoplasm, most frequently located in the salivary gland; extrasalivary cases most commonly occur in the palate. This tumor is prone to recurrence. We present a case of recurrent myoepithelioma in the nasal cavity with a palatal fistula treated both by a palatal approach and a piriform apertural approach. The combination of these approaches widens the su...
