A Case Report of Gastric Cancer Accompanied by Dermadrome Disappeared following Tumor Resection

Abstract

We reported a case of dermadrome acommpanied by gastric cancer. A 71-year-old man admitted for epigastralgia was found in Gastrointestinal scopy to have huge type 2 gastric cancer. Abdominal computed tomography showed multiple lymph nodes metastasis, necessitating neoadjuvant chemotherapy with CPT-11 and TS-1. The main tumor and metastatic lymph nodes shrunk dramatically in size, but severe refractory systemic erythema annulare was recognized during fourth course of chemotherapy. We considered dermadrome and conducted distal gastrectomy. Systemic erythema annulare gradually transformed into pigmentation with a crust, almost disappearing after surgery on postoperative day 27th. The man died due to multiple liver metastasis and peritonitis carcinomatosa. Skin lesion recurrence was not seen during the postoperative course.
