Extramedullary Plasmacytoma of the Pancreas: A Rare Entity

Extramedullary plasmacytomas are plasma cell neoplasms in organs other than the bone marrow. Most are found in the upper respiratory tract. Involvement of the pancreas is rare. We report a case of pancreatic plasmacytoma in association with advanced multiple myeloma

Metastatic squamous cell carcinoma to the colon arising from a mature cystic ovarian teratoma

Malignant transformation of a mature cystic teratoma is extremely rare, occurring in 0.17-2% of cases.1 The most common malignant degeneration is squamous cell carcinoma (SCC) arising from the ectoderm. Approximately half of all cases of SCC of the ovary are confined to the ovary at time diagnosis.1,2 Secondary to its absolute rarity and the relative infrequency of cases with metastatic spread the optimal treatment of advanced stage disease is unknown. Outcomes for locally advanced and widespread disease have historically been very poor. Ford and Timmons recently reported on a patient with stage IIC SCC arising in a mature cystic teratoma treated with multimodal therapy who has been free of disease for more than five years.3 Herein we report on a woman with stage IIIC SCC arising within a mature cystic teratoma treated with directed chemoradiation who subsequently developed metastatic SCC to the colon

Dilemmas in distinguishing between tumor and the posttraumatic lesion with surgical or pathologic correlation.

This article discusses the most common diagnostic dilemmas when trying to distinguish between tumor and sports injury or other trauma. Bone tumors frequently occur in the same young active patients who experience sports injuries. If the pain persists longer than expected, imaging studies should be obtained to prevent a delay in diagnosis or an inappropriate arthroscopy. A history of spontaneous fracture or a fracture after minor trauma should raise suspicion for underlying lesion as the cause. Occasionally necrosis and/or hemorrhage within a soft tissue sarcoma is so extensive that only a small cuff of viable tumor tissue is present
