Primary jejunal amelanotic melanoma: case report and review of literature.

Abstract

Intussusception more commonly occurs in pediatrics but is a rare cause of bowel obstruction and gastrointestinal bleeding in adults. It typically occurs in adults due to a malignancy, which serves as a pathologic lead point. We present a case of a 64-year-old female with nausea, vomiting, and melena who was found to have intussusception associated with a primary jejunal amelanotic melanoma. Both intussusception and primary small bowel melanomas are rare causes of obstruction and bleeding. Intussusception occurring as a result of a primary small bowel amelanotic melanoma is exceedingly rare with very few reported cases. We provide a case report and review of the literature.
