Abstract

A previously healthy 17-year-old male presented for evaluation of a left medial elbow soft tissue mass with associated burning radiating pain down into his volar forearm. He had reported slight increase in size of the mass over the past couple of months. The patient was initially evaluated by ultrasound and then by MRI. Patient underwent total surgical excision of the mass, which was submitted for histopathological evaluation. Pathology identified the mass as a 3.0 × 1.7 × 1.5 cm high-grade tumor with negative surgical margins that was surrounded by an intact capsule measuring less than 0.1 cm. Immunohistochemistry revealed S-100 protein, which was diffusely and strongly positive. To establish a wide negative margin, the patient underwent tumor bed re-excision.
