Cutaneous melanoma is a common and aggressive neoplasm, and metastases to the gastrointestinal tract mainly affect the small intestine, colon, and stomach. Gallbladder metastasis is uncommon. We present a case of melanoma metastasis in the gallbladder in a 40-year-old man with a previous diagnosis of cutaneous melanoma in the dorsal region. The purpose of this article is to reinforce the importance of imaging exams, adding PET scan as another useful method in patients with melanoma in follow-up.
