Intraneural angioleiomyoma of the median nerve presenting as a forearm mass: A case report

Özet

Angioleiomyoma is a solitary form of leiomyoma which is typicallyencountered in the subcutis. They are mostly seen in lower extremities, and the upper extremity is the second most common location for these lesions. There are onlya few reports about the presence of an angioleiomyoma within a peripheral nerve in the upper extremity. Here we report a 56-year-old male patient who was referred to our clinic after an attempt was made for removal of a forearm mass at another institution. The lesion was encased within the median nerve and there was an unusual hypervascularity around the tumor with numerous vessels entering the lesion. Removal of the tumor without apparent damage to nerve fascicles was possible. Histopathological examination of the excision material revealed an intraneural angioleiomyoma. Following surgery, the patient was free of any functional deficits and no evidence of recurrence was observed at one year follow-up. There is no data regarding recurrence in intraneural lesions due to the lack of a large series. It would not be wrong to recommend spare grossly uninvolved fascicles if the nerve in question is not expendable.
