A Rare Case of Cavernous Intramuscular Hemangioma of the Forearm.

Cavernous intramuscular hemangiomas are a part of a group of rare benign tumors. This case report outlines a unique instance involving a 72-year-old patient who sought medical advice at our department due to a progressively enlarging mass in the posterior aspect of her right forearm. Physical examination revealed a painless, mobile mass with no apparent skin abnormalities. Radiographs showed normal results, and an MRI raised suspicion of a fibrous tumor. A subsequent biopsy confirmed the diagnosis of cavernous hemangioma. The patient underwent a total excision procedure, resulting in favorable outcomes with no observed functional impairment or tumor recurrence over four years. This case is notable for its singularity, involving both the advanced age of the patient and the uncommon location of the tumor.
