title: Case report: subcutaneous metastasis from small cell carcinoma of the prostate.
abstract: Pure primary small cell carcinoma of the prostate (SCCP) is an extremely rare entity. Natural history of this tumor is similar to that of the bronchogenic small cell carcinoma. Several theories of histogenesis have been proposed. Most widely accepted view is that SCCP arises from pluripotent stem cells of the prostate, which have the ability to differentiate into either epithelial or neuroendocrine type carcinomas. SCCP has an aggressive course, and a majority of patients have distant metastasis at presentation. Since it is a rare entity, no standard treatment regimen has been established. A case of primary pure SCCP with multiple subcutaneous metastases is presented.
