Glomangiosarcoma of the hypothenar eminence : a case report

Abstract Glomangiosarcoma is an exceptionally rare soft tissue tumor. It tends to appear as a painful nodule located in the subcutaneous tissue. There are only two cases described on the hand before instead of the benign glomus tumor is usually located at this level. Histochemically the glomangiosarcoma shows features that remind a benign glomus tumor, except for the malignant glomus tumor arising de novo. This neoplasm is considered a low grade malignant tumor with tendency to local recurrence, though metastasis have been reported. We report the case of a 36 year- old -woman with a glomangiosarcoma in a glomus tumor in the hypotenar eminence. The treatment was a local complete excision and there was no signs of recurrence after 18 months.
