Case Report: Chest-Wall Lump Yields a Surprising Diagnosis

To the Editor: A 17-year-old patient presented with a solitary lump over the right chest wall of three years' duration. The patient reported that the lump was causing discomfort during contact sports and had an unattractive appearance. Clinical examination revealed a nontender, firm, and side-to-side mobile subcutaneous lump obliquely overlying the right anterolateral chest wall (Figure 1). Ultrasonography revealed a nonspecific solid heterogeneous mass measuring 76 mm × 26 mm × 18 mm. A punch biopsy result was inconclusive. Chest radiography and computed tomography were not considered practical imaging tools for this patient, and magnetic resonance imaging was not readily accessible. The patient was scheduled for an incisional biopsy under local anesthesia, with the option of excising the whole lump to avoid multiple procedures.
