A 33-year-old man presented with a lump at the right side of chest wall of 4 months duration which started bleeding suddenly from an ulcer at its center. Examination revealed a globular ulcerated mass 2 cm in diameter, on the anterior axillary fold, with adherent clot at its center. No regional lymphadenopathy was noted. Wide local excision with 2 cm margin was done. Biopsy report revealed malignant small round-cell tumor. Immunohistochemistry showed it to be cytokeratin-20-positive and S100-negative, suggesting the diagnosis of Merkel cell carcinoma. The patient did not receive any other adjuvant therapy. He is being followed-up for the last 4 years and has shown no features of recurrence so far.
