Metastatic amelanotic melanoma with occult primary masquerading as sarcoma

Malignant melanoma with occult primary is extremely rare. It is found that survival is almost same or even better than the melanomas with known primary site. Surgeons should have a high index of suspicion when a patient presents like sarcoma which bleeds profusely when planning for excision. Here, is an unusual case of young adult which presented initially with granulomatous lymphandenitis in axilla with primary suspicion of tuberculosis, later turning out to be sarcoma on FNAC and MRI. On immunochemistry (IHC), the final diagnosis of amelanotic melanoma was made and further workup did not show up any primary site of origin.
