Background:Myopericytoma (MPC) is term that describe a rare group of perivascular tumours of soft tissue and show a range of histological growth patterns. Only a few cases describing MPC have been reported. Aims: To document and investigate the clinical and histopathological characteristics and differential diagnosis of myopericytoma. Patients/methods: The present study reports a unique case of myopericytomas found in the 2nd and 3rd inter-toe spaces of a 54-year-old patient. Results: a 54 year old female patient, presents in our department for a painless mass on the dorsal surface of the right forefoot of progressive installation over 2 years.The mass was firm, non pulsatile and mobile, with no sign of inflammation, evolving in a context of conservation of the general state. The X-ray of the right forefoot did not reveal any notable bone abnormality. An MRI was subsequently performed, which objectified an infiltrating tumor mass of probable sarcomatous origin. The mass was excised surgically, and a pathological and immunohistochemical examination was performed afterward, the diagnosis of myopericytoma was confirmed. No recurrence was found in the follow-up of 12 months. Conclusions: MPC is a rare and mostly benign tumor that presents as spindle cells in a concentric perivascular growth model with an immunohistochemical staining positive for smooth muscle actin. Local recurrences and rarely metastases may occur in atypical and malignant neoplasms.
