Abstract
Malignant melanoma is an aggressive neoplasm with a high tendency to metastasize. Gastrointestinal metastases, although described in the literature, are infrequent. We present the case of a 51-year-old male patient with a surfcial spreading melanoma stage IIIc with BRAF mutation who presented a gallbladder outgrowth lesion, compatible with a polyp. A signifcant growth of the lesion was observed in subsequent TC studies and a laparoscopic cholecystectomy was performed. The anatomopathological study of the specimen confrmed the diagnosis of gallbladder metastasis due to epithelioid and spindle cell malignant melanoma. The presence of a gallbladder lesion in the context of a patient diagnosed with melanoma should establish the diagnostic suspicion of metastasis, and an early extension study and laparoscopic cholecystectomy should be considered. The palliative surgical approach to avoid hepatobiliary symptomatology can be considered.
