Summary
Anorectal melanoma is a rare cancer with non-specific symptoms, making diagnosis challenging. Surgical treatment is key, but survival rates remain low, emphasizing the need for early detection and effective management strategies.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Anorectal melanoma is a rare and aggressive malignancy with non-specific clinical presentations.
- Current treatment strategies for anorectal melanoma are not well-established, contributing to its high lethality.
Observation:
- A 66-year-old male presented with rectal bleeding and pain, initially diagnosed as a rectal polyp.
- Histopathology confirmed anorectal malignant melanoma; staging revealed lung metastasis.
- The patient underwent local excision and lung metastasectomy, with no adjuvant therapy.
Findings:
- Malignant melanoma of the anorectum can be difficult to diagnose due to vague symptoms and potentially misleading histology.
- Surgery, particularly wide local excision with adjuvant radiotherapy, is the primary treatment modality.
- Abdominoperineal resection is reserved for extensive tumors involving the anal sphincter.
Implications:
- Early diagnosis and prompt surgical intervention are crucial for improving outcomes in anorectal melanoma.
- The overall 5-year survival rate for anorectal melanoma is less than 20%, significantly influenced by disease extent.
- Further research into optimal adjuvant therapies and treatment protocols is warranted to improve patient survival.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
