Acral Myxoinflammatory Fibroblastic Sarcoma: Report of a Case and Treatment with Mohs Micrographic Surgery.

Acral myxoinflammatory fibroblastic sarcoma (AMFS) represents a low-grade sarcoma with a high rate of local recurrence that commonly affects the distal extremities. The lesion often presents as a painless mass in the hands or feet. There is no formal standardized treatment protocol for this tumor, but wide surgical excision, with or without adjuvant radiation therapy, is the conventional treatment. We report a case of a patient with an AMFS treated with Mohs micrographic surgery (MMS) without recurrence. Because of the propensity of this tumor to involve acral sites where tissue conservation is important, MMS might be an alternative treatment modality for this rare entity.
