Solitary radial head metastasis with wrist drop: a rare presentation of metastatic prostate cancer.

The fact that a prostate carcinoma metastasizes to the skeleton is well known. The metastatic deposits are generally multiple and osteoblastic. Moreover, these involve the axial skeleton or the proximal part of long bones. A pure osteolytic metastasis from a prostate carcinoma is extremely rare. This is believed to be the 1st case report of a osteolytic solitary radial head metastasis from a prostate carcinoma in a 60-year-old male. The rare clinical presentation of wrist drop, the absence of metastases at any other site, and a significant decrease in the size of lesion on follow-up in response to hormonal therapy are of interest in this case. The rare clinical presentation of a common malignancy (prostate carcinoma) is reported with a brief review of the literature.
