“…Histopathologically, the MPC is characterized by the proliferation of round-to-ovoid spindle-shaped cells with eosinophilic cytoplasm arranged in a perivascular concentric pattern [ 3 , 4 , 15 ]. Some cases may exhibit blood vessels arranged in hemangiopericytoma-like patterns [ 15 ].…”

This report describes the case of a 29-year-old male who presented with painless swelling on the volar aspect of his right middle finger. The initial clinical impression was consistent with an epidermal inclusion cyst. A plain radiograph of the lesion revealed a circumscribed superficial nodular soft tissue mass confined to the dermis of the affected finger. Following surgical excision and subsequent histopathologic examination, the lesion was ultimately identified as a myopericytoma (MPC). The occurrence of MPCs in the finger is uncommon; thus, a high level of suspicion is required to consider it as one of the differential diagnoses for painless nodules in this anatomical location. Surgery serves as the primary method for treatment, and histopathologic evaluation plays a crucial role in confirming the diagnosis and ruling out malignancy.
