A Rare Presentation of Sclerosing-Type Rhabdomyosarcoma in an Underserved Patient: A Case Report

A man in his early 40s, with no previous medical history, presented to the emergency room with right leg swelling. It had started more than one month prior to the presentation, but the patient had not sought medical attention due to lack of insurance. He underwent an ultrasound, computed tomography (CT) scan, and magnetic resonance imaging (MRI). The studies revealed a mass in the right vastus medialis muscle. A biopsy revealed a high-grade rhabdomyosarcoma (RMS) with sclerosing features. The patient started treatment with vincristine, actinomycin D, and ifosfamide (VAI). He continued chemotherapy as an outpatient, but was lost to follow-up. He returned four months later with metastatic disease.
