RESUMO
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.

A report on compression of the median nerve in distal forearm and wrist by an accessory muscle (the palmaris bitendinous) is described. Its position, deep to the palmaris longus, and distal insertion on the deep surface of the superficial aponeurosis were similar to palmaris profundus. Nevertheless, both its tendinous-musculo-tendinous structure and the origin from the dorsal epimysium of the palmaris longus muscle belly were unlike palmaris profundus.

One of the most important parameters for success in free tissue transfer to the head and neck are a proper and careful recipient vessel dissection and meticulous vascular microanastomotic technique. The principle that govern vessel positioning in the head and neck are more complex than those used in extremity free flap transfers. In this report the vascular selection as well as technical details are discussed, based on the literature data and our own experience in 20 patients.
