Intramuscular myxoma of the hypothenar muscles

Abstract

Intramuscular myxomas of the hand are rare entities. Primarily found in the myocardium, these lesions also affect the bone and soft tissues in other parts of the body. This article describes a case of hypothenar muscles myxoma treated with local surgical excision after frozen section biopsy with tumor-free margins. Radiographic images of the axial and appendicular skeleton were negative for fibrous dysplasia, and endocrine studies were within normal limits. The 8-year follow-up period has been uneventful, with no complications. The patient is currently recurrence free, with normal intrinsic hand function.

Intramuscular myxoma of the left leg—Case report of the lesion observed for several years

“…In view of the fact that myxomas are benign neoplasms, which are not capable of forming distant metastases, and the percentage of local relapses of cellular myxoma is less than 10%, radical resection of the lesion is recommended. [17][18][19] So far, the available literature has described no case of distant metastases in a patient with a myxoma. However, there have been descriptions of relapses after non-radical resection.…”
