Udaipur: Primary anorectal malignant melanoma, commonly referred to as “black pigment cancer,” is an extremely rare but aggressive form of cancer. It is often mistaken for common conditions such as haemorrhoids, skin tags or other anal disorders, which can delay diagnosis.

Recently, a 51-year-old patient was successfully treated at Geetanjali Hospital, Udaipur, under the leadership of Dr. Pankaj Gupta, HOD, Department of Gastroenterology; Dr. Ashish Jhaketia, Cancer Surgeon; and Dr. Kartikeya Mathur, Department of Gastroenterology.

The patient had been experiencing intermittent bleeding from the anus, burning and discomfort for nearly a year. Initial examination revealed a large, polyp-like suspicious mass measuring 5×8 cm in the anal region. Using an advanced minimally invasive technique, the mass was removed completely through the anal opening without the need for major surgery. The patient did not require hospitalisation and was discharged within a few hours.

Importantly, detailed investigations found no evidence of metastasis or spread of the cancer to other parts of the body.

According to the doctors, anorectal malignant melanoma has a high potential for rapid spread, making early detection extremely important. Advanced investigations such as MRI and CT scans are essential for accurate staging and assessment of the extent of the disease.

Surgery remains the primary treatment, generally involving complete removal of the affected area. In advanced cases, this may require creation of a permanent artificial opening for stool passage, connected to a lifelong colostomy bag. Chemotherapy and radiation therapy have a more limited supportive role in treatment.

Experts have urged people not to ignore symptoms such as anal bleeding, a lump, pain or persistent discomfort. Timely medical evaluation and accurate diagnosis can significantly improve the chances of effective treatment. Lack of awareness often leads patients to seek medical attention at a later stage, making treatment more challenging.

Doctors also emphasised the importance of regular follow-up and periodic investigations after treatment to detect any recurrence or spread of the disease at an early stage.

Greater public awareness about this rare but serious cancer can play an important role in ensuring early diagnosis and improving treatment outcomes.
