Two Case Reports of Angioleiomyoma of the Finger.

Angioleiomyoma in the extremities is a benign smooth muscle neoplasm arising from the small blood vessels of the muscle. It was first described in 1937 by AP Stout, who reviewed the literature on solitary cutaneous and subcutaneous leiomyomas and added 15 more cases from his own clinic-pathologic findings.

We found 40 articles about magnetic resonance imaging findings in angioleiomyoma using PubMed online. Many authors reported that angioleiomyomas showed different types of signal intensity on MRI.

There are very few reports about pathological and radiological correlation in angioleiomyomas. We report the pathological
and radiological correlation of 2 cases of angioleiomyoma in the finger seen in our hospital and observed on MRI using a microscopy coil.

A 72-year-old man came to our observation because of the presence of a mass on his left middle finger, which had been hurting for the recent two weeks. The mass was present for approximately 30 years without pain or increase in size.

On physical examination, the mass was slightly mobile, approximately 1 cm in size and located subcutaneously just adjacent to the radial side of distal phalanx of the left third finger. Overlaying skin was intact. Range of motion of the proximal and distal interphalangeal joints of the third finger was complete.

He had no history of trauma on the site of lesion. Radiograph of the finger showed an oval-shaped soft tissue mass lesion on the radial side of the distal phalanx.
