[2],[3] Histopathologically, myopericytoma is characterized by a well-circumscribed, nodular proliferation with numerous thin-walled blood vessels and a concentric, perivascular arrangement of ovoid spindle-shaped cells with eosinophilic cytoplasm and vesicular nuclei in the dermis, subcutis, or soft tissues. Histopathological examination of the biopsy revealed spindle-shaped myoid-appearing cells in a concentric arrangement, associated with thin-walled vascular channels with no mitotic activity or cytologic atypia [Figure 2]a and [Figure 2]b. Immunohistochemically, although the perivascular cells were focally positive for CD34 and CD31 for SMA, desmin was negative [Figure 2]c. After correlating clinical and histopathological findings and the immunohistochemical pattern, we diagnosed this lesion as myopericytoma. Because of complaints of ongoing pain in her scalp, she was referred to plastic surgery for total excision. [4] We believe that this case will help other physicians to recognize this rare entity and to improve the understanding of myopericytoma which should be kept in mind in the differential diagnosis of nodular lesions.
