Abstract

Myofibromatosis is a proliferative disorder characterized by the development of soft tissue neoplasms referred to as myofibromas that predominantly occur in infants and young children. These lesions have been described using varied terminologies since they were first reported in 1951. However, these neoplasms are histopathologically characterized by benign fibroblast and myofibroblast proliferation containing a biphasic presentation of spindle-shaped cells surrounding a central zone of less differentiated cells arranged in a hemangiopericytoma-like pattern in all cases. Usually, myofibromatosis occurs in children aged <2 years and is observed at birth in nearly 60% of cases. We report a rare case of myofibroma in an 8-year-old boy who presented with an approximately 6-month history of a left postauricular mass. Histopathological evaluation of the resected mass confirmed the diagnosis.
