a 22-year-old man presented with exertional dyspnea commencing one month prior to his admission. echocardiography revealed a non-homogenous mass, and the pathology examination of the pericardial biopsy was compatible with angiosarcoma.

lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. some studies show that less than 1% of lipomas were ossified. we describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. to the best of the authors' knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and h...

Sarcomatoid squamous cell carcinomas are extremely rare, high grade, aggressive variant of penile cancers. Sarcomatoid carcinoma are biphasic neoplasms with a combination of both sarcomatoid components and carcinomatous elements. These neoplasms are very rare in the urogenital system. We report a 53-year-old male presented with an ulcerated lesion on the glans penis. The rarity of this case rei...
