Abstract
Myopericytoma is a rare, slow-growing benign neoplasm that usually manifests in soft tissues, commonly affecting the lower extremities. Here, we present a case report of a 55-year-old male patient with hypertension and epilepsy, with no history of trauma, who complained of a well-circumscribed, reddish mass located on the fourth finger of his left hand. It was painless, but caused mechanical discomfort due to the mass. The mass had been growing slowly for approximately 6 months. Both ultrasound and soft tissue magnetic resonance imaging (MRI) showed a solid, oval, nodular tumor with marked vascularity on the flexor surface of the fourth finger of his left hand. The lesion was surgically excised, and histopathological evaluation identified it as a myopericytoma.
The objective of this article is to report an unusual presentation of this tumor and provide a review of the available literature.
