Spontaneous Involution (Regression) of a Solitary Cutaneous Myofibroma in an adult patient: Case Report

Abstract:

Myofibromas are unusual benign tumors most commonly seen in infant children. Clinical involution of the tumor often occurs within the first few years of life. Solitary cutaneous myofibroma is the synonymous adult counterpart of infantile myofibromatosis. Although solitary myofibromas have been reported in patients of all ages, only the infantile variant is believed to regress spontaneously. There are only a few case reports of adolescent and young adult patients with regressing solitary lesions that have been described in the literature to date.¹

We report a 71-year-old male with spontaneous regression of solitary cutaneous myofibroma. The residual lesion was excised and to date has not recurred. This report describes the historical, clinical, and histopathological features of adult myofibromas and a novel manifestation that may guide future clinical considerations when approaching solitary tumors with regressive features.
