“…9 cases arose within vessels showing an attachment to the vascular wall. (18)(19)(20) and in 3 cases lesion developed secondary to trauma or previous scar. Histologically these lesions were well circumscribed, with exception of 4 cases that had ill defined border and an infiltrative pattern.…”

“…Woollard et al described a case where a benign myopericytoma arose intravascularly in the superficial arch of a 63-year-old man [10]. The gross appearance demonstrated a spherical swelling of the vessel wall, while histology revealed endothelial cells surrounded by undifferentiated smooth muscle cells.…”

Myopericytomas belong to a benign group of tumors consisting of perivascular myopericytes or pericytes with a characteristic myoid differentiation pattern. The tumor is histologically and radiographically heterogenous, similar to superficial myofibromas. We report on a case of a myopericytoma arising in the hypothenar eminence of a 58-year-old man with a history of over 15 years of ulnar-sided and midcarpal wrist pain. Decision was made to excise the mass after it had increased in size by over 50 % over a 10-year period. Excision of the mass led to remarkable relief of his symptoms in the hypothenar as well as midcarpal regions. Consideration of this rare perivascular tumor should be included in patients with slow-growing benign appearing masses within the subcutaneous tissues of the hand.

“…It is described only in case reports in the orthopaedic literature [1,12] and was delineated as a distinct entity by pathologists in the 1990s [4]. Most perivascular tumors had been divided into either glomus tumors or hemangiopericytomas previously [9].…”

A 36-year-old right-hand-dominant woman presented with a 2-month history of intermittent sharp stabbing pain in the left palm. She denied any history of distinct trauma or infection in the area. She was active as a college Frisbee coach and played golf recreationally. Severe pain occurred only when playing Frisbee or golf or during handshaking. The patient denied pain at night. On inspection of the hand, there was no visible mass or deformity. Physical examination of the hand revealed firmness in the palm at the base of the third metacarpal. This area was locally tender to palpation, and pressure applied to this area reproduced the patient's painful symptoms. There were no skin changes overlying the affected area. Motor and sensory function were preserved in median, radial, and ulnar nerves. Twopoint discrimination was preserved distally at the fingertips. The patient had full range of motion at the wrist and in the metacarpophalangeal joints and interphalangeal joints of all digits. Tinel's sign was negative at the wrist, and Allen's test revealed patency of the radial and ulnar arteries.We initially obtained plain radiographs of the affected hand. These films were interpreted as normal. Subsequently, MRI was performed to better characterize the location and nature of the mass (Figs.
