Follicular dendritic cell sarcoma. Clinicopathologic analysis of 17 cases suggesting a malignant potential higher than currently recognized.

Abstract

Follicular dendritic cell sarcoma exhibits distinctive histologic features that permit its presumptive recognition, but a firm diagnosis requires confirmation with special studies. Because it has a significant recurrent and metastatic potential (the latter risk having been previously underestimated), it should be viewed as an intermediate grade malignancy. An intraabdominal location is associated with a particularly aggressive clinical course.
