Abstract
We present a case of a 44 year-old man with histiocytic sarcoma arising from the rectum. Histiocytic sarcoma is a rare type of malignant lymphoma, comprising less than 0.5% of all non-Hodgkin's lymphomas (NHLs). In this case, the tumor was a polypoid mass, measuring 2.5 x 2 cm. On microscopic examination, it was composed of many bizarre multinucleated cells and sheets of xanthomatous histiocytes. There were also areas with spindle cells arranged in a storiform pattern. Extensive metastases to regional lymph nodes were found, and combined adjuvant chemotherapy was administered after complete resection.
