We present a 76 year old male with cutaneous malignant melanoma of the dorsal region, who underwent surgical excision and axillary lymph node dissection (pT2bpN3bM0), followed by adjuvant therapy with pembrolizumab for 1 year. Reassessment PET scan after immunotherapy showed a single hypermetabolic foci in the ascending colon. On colonoscopy, a 7mm sessile was found and excised by cold snare polypectomy. Histopathology revealed intestinal mucosa infiltrated by solid malignant neoplasia positive for SOX-10, HMB45, MelenA and S100, compatible with intestinal metastasis of malignant melanoma. Due to low performance status for further treatment, surveillance with PET was decided.
