Abstract:
Malignant melanoma is the most lethal skin cancer. While it represents about 5% of all cutaneous malignancies for men and women, melanoma accounts for the most skin cancer deaths. Symptomatic gastrointestinal involvement from primary malignant cutaneous melanoma is uncommon and represents only 1% to 4% of melanoma cases but is found in 60% of autopsies in patients who have had a primary cutaneous melanoma. We present a case of metastatic melanoma in a 61-year-old man with initial symptomatic cecal melanoma and subsequent jejunal involvement discovered during endoscopy.

Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...
