Inferior vena cava leiomyosarcoma with liver metastasis at presentation in a young male: A challenging diagnostic quandary

Leiomyosarcomas of vascular origin are very rare tumors, predominantly affecting the inferior vena cava (IVC). Although vascular leiomyosarcomas are slow-growing, their non-specific and late presentation results in delayed diagnosis which portends a very poor prognosis. Here we report a case of a 24-year-old man who presented with abdominal pain since 15 days and was found to have unresectable metastatic leiomyosarcoma of the inferior vena cava at initial diagnosis.

Giant cystosarcoma phyllodes tumor of prostate: case report of a rare entity.

Although glandular and stromal proliferations of prostate are very common in adult men, neoplastic proliferations of prostatic stroma are distinctly uncommon. These tumors are now grouped as Prostatic Stromal Proliferations of Uncertain Malignant Potential (PSPUMP). Phyllodes tumor of the prostate is a rare neoplasm in this group with cellular, sarcomatoid stroma and benign hyperplastic glands. It is a locally expansile tumor with clinical course varying from benign to aggressive. We report a case of a 45-year-old man presented with retention of urine and abdominal lump. On laparotomy it was a huge tumor of 4 kg and was histologicaly characterized by cellular pleomorphic stroma and hyperplastic epithelium. Immunohistochemistry demonstrated prostate specific antigen in the glands. It was diagnosed as cystosarcoma phyllodes tumor of prostate. This is extremely uncommon tumor similar in histology to that of breast and it's clinical course varies with the grade. The patient was without recurrence one year after surgery.
