“…10,14,15,23 However, as noted in our study, patients may have no GI symptoms. Similar to findings in previous studies, 5,23-25 and contrary to expectations, most of the small-bowel melanoma metastases in our study were nonpigmented polypoid lesions, with or without ulceration and bleeding.…”

“…Unfortunately, the sensitivity of these imaging techniques does not exceed 60%-70%, suggesting that they provide inadequate preoperative information, apart from the detection of large lesions. 11 Their low sensitivity also helps to explain the discrepancy between autopsy results and pre-mortem GI fi ndings. 16 Our patient underwent MRE as well as CT scans.…”

Ileal Malignant Melanoma Causing Intussusception: Report of a Case

et al. 2007

Cutaneous malignant melanoma (MM) often metastasizes to the gastrointestinal (GI) tract; however, primary MM of the small intestine is a controversial diagnosis. We report the case of a 76-year-old woman found to have a primary MM in the ileum. After clinical evaluation, the radiological workup, which included magnetic resonance enteroclysis (MRE), revealed a large polypoid intraluminal tumor. She underwent laparotomy and the lesion was excised. Histological examination of the resected specimen revealed morphological and immunohistochemical characteristics of MM and a detailed postoperative examination failed to identify a primary lesion on the skin, anus, oculus, or any other site. The patient died of brain metastasis 6 months after surgery. According to our review of the literature, this is the first case of primary MM of the small intestine diagnosed with the help of MRE.

“…Surgical radical treatment should be the treatment of choice [1,2]. Unfortunately, metastatic involvement of the small bowel has a rather late presentation not only in melanoma cases but in other malignancies too [3,4].…”

Small bowel intussusception due to metastatic malignant melanoma. A case report

et al. 2004

View full text Add to dashboard Cite

Small bowel metastatic deposits attributed to malignant melanoma are found in 2-5% of patients with malignant melanoma of the skin. Ileo-ileo intussusception caused by metastatic melanoma is a very rare condition. The prognosis of metastatic melanoma is poor. We report a case of a cutaneous malignant melanoma which metastasised to the small bowel causing enteroenteric intussusception. This case refers to a 66-year-old male patient who underwent surgery for suspected enteric intussusception. This diagnosis was suggested by computer tomography scan. The patient had had previous surgery for a primary malignant melanoma in the eyelid of the right eye. Segmental intestinal resection with regional lymph node dissection and ileo-ileo anastomosis was performed. Metastatic melanoma in the gastrointestinal tract should be suspected in patients with history of melanoma of the skin and acute gastrointestinal symptoms. Immediate laparotomy and excision of the affected bowel segment is the appropriate treatment.
