It is distinguished by its concentric layering of spindle shaped myoid appearing cells perivascularly. These cells diagnostically stain positive to alpha smooth-muscle actin and rarely positive to desmin stain. This case study reviews the presentation of a 56-year-old male with a slow-growing, pre-tibial lesion developing over a 7–8 year period. This lesion was asymptomatic and demonstrated vascular involvement on ultrasound scan. This lesion measured 19 × 15 × 9 mm histologically and contained bland spindle cells surrounding vessels that interestingly stained positive to both alpha smooth-muscle actin and desmin. The histological findings in correlation to clinical presentation and imaging led to a diagnosis of MPC.","claims":[{"public_id":"cl_81838ccf7c52ad4bf5aefad73f966c50","status":"active","text":"A
