Intramuscular myxoma of the biceps brachii muscle: a case report

Lina Pankratjevaite et al. J Surg Case Rep. .

Abstract

Intramuscular myxoma (IM) is a rare benign tumour. It may occur at any age but most commonly occurs among older women. The preoperative diagnosis of IM is complicated. The diagnosis can only be definitively established by histopathological examination. The treatment of choice is radical surgical excision. We report a case of a 41-year-old woman with an IM of the biceps brachii muscle.

Keywords: benign; biceps brachii; intramuscular; myxoma; tumour.
