Metastatic melanoma of the gallbladder: An unusual clinical presentation of acute cholecystitis

摘要

Metastatic disease from cutaneous melanoma can af-fect all organs of the body, and varies in its biological behavior and clinical presentation. We present the case of a 58-year-old man who arrived at our clinic with acute abdominal pain, which, after investigation, was diagnosed as acute cholecystitis. The patient under-went laparotomy and cholecystectomy. Two years ago, he underwent surgical removal of a primary cutaneous melanoma on his right upper back. Pathological exami-nation revealed the presence of malignant melanoma with a metastatic lesion of the gallbladder.
