Challenges in managing anorectal melanoma, a rare malignancy

Area of Science:

• Oncology
• Gastroenterology
• Dermatology

Background:

• Anorectal melanoma is a rare, aggressive malignancy.
• Diagnosis can be challenging due to nonspecific symptoms.

Observation:

• A 69-year-old woman presented with painful defecation, rectal bleeding, and an anal mass.
• Initial diagnosis considered hemorrhoids or polyps.
• Histopathology confirmed anorectal mucosal melanoma.

Findings:

• Surgery is the primary treatment, but complete resection is often difficult.
• High rates of local recurrence and distant metastasis are common.
• No locoregional or distant metastasis was found in this case.

Implications:

• Highlights the importance of considering anorectal melanoma in differential diagnoses.
• Emphasizes the need for a multidisciplinary approach in managing anorectal melanoma.
• Further research is needed for tailored treatment strategies.
