Melanoma of Unknown Primary Origin: A Case Report and Literature Review

Puntos clave

Metastatic melanoma can occur without a known primary lesion, posing unique challenges in management.
Recognition of melanoma of unknown primary origin is essential for effective treatment strategies in stage IV cases.
Treatment typically involves systemic therapies similar to those for other metastatic melanoma types, such as immune checkpoint inhibitors.
Standardized management protocols can optimize patient outcomes, indicating the need for prompt intervention.

Resumen

MUP is an uncommon and challenging presentation of metastatic melanoma. Its pathogenesis remains unclear, although several theories, including immune-mediated regression of the primary lesion, have been proposed. MUP should be staged as stage IV disease and treated with the same systemic therapies used for stage IV MKP, including immune checkpoint inhibitors and targeted agents. Prompt recognition and standardized management are crucial to optimizing outcomes in this subset of patients.
