Malignant melanoma of the rectum: a case report
Malignant melanoma of the rectum: a case report
Published: December 2009
Abstract
Introduction
Anorectal melanoma represents an unusual but important presentation of rectal malignancy. There have only been a few cases reported and the optimum management for this condition is still undecided, however, prompt diagnosis is essential. We have outlined current treatment options.
Case presentation
We report a case of malignant melanoma of the rectum in a 55-year-old Caucasian man presenting as an emergency with rectal bleeding. Biopsies were taken of the fleshy mass found on digital examination, which confirmed malignant melanoma. No distant metastases were found. He underwent an abdominoperineal resection. We report the surgical management of this rare and aggressive malignancy.
Conclusion
Treatment options for this condition are divergent. Surgical management varies from wide local excision to abdominoperineal resection. Clinical awareness in both medical and surgical clinics is required for prompt diagnosis and treatment.
Introduction
In this patient, an emergency presentation of rectal bleeding led to an unusual diagnosis. Rectal bleeding is a common presentation of rectal malignancy. An uncommon form of this is malignant melanoma, attributing to only 1% of all rectal malignancies. Due to the aggressive nature of this disease, an early diagnosis and prompt treatment are essential.
