adenocarcinoma of the rectum with cutaneous metastases

cutaneous metastases of rectal carcinoma is a rare event. it occurs in fewer than 4% of all patients with rectal cancer. when present, it typically signifies a disseminated disease with a poor prognosis. early detection and proper diagnosis of metastatic rectal cancer can significantly alter treatment and prognosis. we report a 70-year-old male who underwent rectal resection with permanent colostomy for rectal adenocarcinoma since seven years. the patient recently developed multiple skin nodules, mainly in his face, scalp, and upper trunk, associated with itching. fine needle aspiration cytology from a face nodule was done which revealed metastatic adenocarcinoma associated with severe inflammation. cutaneous metastasis of rectal adenocarcinoma is an unusual event that presents mainly in the form of skin nodules and could be the first sign of metastasis. early diagnosis of cutaneous metastasis in these patients is important because it can alter treatment and prognosis.
