Abstract

Striated muscle hamartoma (SMH) is an uncommon benign lesion, that is usually congenital, polypoid, and primarily located on the head and neck. The key histopathologic sign is the existence of individualized fascicles of striated muscle affecting the dermis and subcutaneous fat tissue. Here we report the case of a newborn girl with an SMH, who presented with a congenital infiltrated plaque on her chin without any other associations.
