Intraperitoneal metastatic malignant melanoma arising from small bowel…… A case report.

Abstract

Small bowel tumors are very rare. Melanoma in small intestine can be primary or metastatic. Metastatic malignant melanoma in small intestine can arise from skin, eyes, oropharynx, esophagus or ano rectal mucosa. Primary malignant melanomas of small intestine are very rare. In this case report, we are going to present primary malignant melanoma of small intestine, which has already metastasized by the time of presentation. A 60 year old male, presented to us with abdominal pain, vomiting and absolute constipation. On exploration, black colored mass of 5x5cm in distal ileum which was attached to posterior wall of urinary bladder on right side and whole of the gut from stomach to rectum was involved. The patient was thoroughly examined and investigated for cutaneous melanoma, but there was no such tumor present. So it was concluded that this patient had primary malignant melanoma arising from distal ileum.
