A myopericytoma (MP) is an exceedingly rare perivascular tumor of unknown etiology. Given their potential for mimicry and malignancy, MP tumors pose a unique challenge for surgeons and may be overlooked on differential diagnosis. We present a case report of an otherwise healthy 33-year-old right-hand dominant male who presented to our outpatient clinic with a 2-month history of painless swelling and erythema of the pulp of his left index finger. Subsequent plain film X-ray showed near-complete bony destruction of his distal phalanx. Pathological evaluation of an incisional biopsy showed a benign variant of MP. The lesion was treated by excision with tumor shelling, and there was no evidence of recurrence 81 days postoperatively. A systematic literature review of the management and outcome of all known cases of hand and wrist MP is presented.

Review
BACKGROUND
Myopericytoma is a perivascular tumor of the skin and subcutaneous tissue of the extremities, it is a rare finding in the head and neck, and even rarer is its deep location.
METHODS
A 38-year-old woman presented with a slowly growing mass at the right carotid triangle. Contrast-enhanced CT scan revealed a moderately enhancing mass. At surgery, the tumor was firmly attached to the common carotid artery, making it necessary to excise a small portion of the vessel wall.
RESULTS
The histopathologic report was myopericytoma. The postoperative course was uneventful, without tumor recurrence.
CONCLUSION
The very few deep located myopericytomas at the head and neck region show a predilection to appear near the great neck vessels with a possibility to require vascular repair, or at the parotid space where they can be multicentric. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2479-E2482, 2016.
