| Abstract |
Introduction Myopericytomas are rare, slow-growing benign peri- intravascular tumors. These are commonly found within the subcutaneous soft tissues of the lower extremities, represented with similar morphology and typical immunohistochemically profile. In MRI, these enhancing tumors are highly vascularized and well-defined. We are reporting a case involving the foot, focusing on the clinical, histopathologic, and radiologic characteristics. Methods Report of a case and literature review. Results A 51-year-old lady with increasing pain on the plantar side of the right foot without local alterations but tenderness between 1st and 2nd metatarsals was consulted in June 2018. The MRI showed a well-circumscribed, hypoechoic mass of 10 x 15 mm at plantar base of the 1st metatarsal with contact to medial part of flexor hallucis brevis tendon, which was compatible with an arteriovenous malformation. An angiology council rather spoke for a solid tumor with good perfusion. The total surgical excision of a well-circumscribed, easily bleeding mass was performed through a medial extended mid foot approach. The anatomopathological examination showed a rare benign intravascular myopericytoma, localized in a vein with a typical immunohistochemically pattern. Conclusion Myopericytoma is a rare benign, peri- intravascular soft-tissue tumor usually found in the lower extremities. Clinical presentation is unspecific and to rule out other malign tumors a total surgical excision is justified. Diagnostic imaging criteria are defined as a solid, hypervascular marked by intravenous gadolinium-contrast enhancement soft-tissue neoformation. An anatompathological examination including specific immunohistochemically analysis is essential for correct diagnosis. Histological findings are peri- or intravascular myoid-spindle cell proliferation accompanied by numerous blood vessels. Differential histopathological diagnosis shows a big variety. |
