Signs and Symptoms
Common Signs and Symptoms of Malignant Anal Melanoma
Malignant anal melanoma, a rare type of cancer, can manifest in various ways. The symptoms may be similar to those of other conditions, making it essential to seek medical attention if you experience any unusual signs.
- Bleeding: Bleeding from the anus or rectum is often the first sign of malignant anal melanoma [2][3]. This bleeding may be minor at first and can be mistaken for hemorrhoids.
- Pain: Pain in the anal area, either constant or occasional, can also indicate the presence of this cancer [4][7].
- Mass or growth: A mass or growth in the anal canal is another possible symptom [1].
- Anal itching: Anal itching (pruritus) may be a sign of malignant anal melanoma, although it's not always present [9].
Other Possible Symptoms
In some cases, people with malignant anal melanoma may experience:
- Pain or pressure in the anal area
- Unusual discharges from the anus
- A lump near the anus
It's essential to note that these symptoms can also be caused by noncancerous conditions. If you're experiencing any of these signs, consult a doctor for proper evaluation and diagnosis.

Diagnostic Tests
Diagnostic Tests for Malignant Anal Melanoma
Malignant anal melanoma can be challenging to diagnose due to its unclear presentation. However, various diagnostic tests can help identify the condition and determine its stage.
- Imaging tests: Imaging tests such as CT scans, MRI, and PET scans may be done to help find cancer, learn how far cancer has spread, or check if cancer has spread to other parts of the body [1].
- Digital rectal exam (DRE): A DRE is a common test for people with anal cancer. During this exam, a healthcare professional inserts a gloved, lubricated finger into your anus to feel the anal canal and rectum for growths or other signs of cancer [2].
- Biopsy: A biopsy involves taking a piece of tissue from the affected area for examination under a microscope. This is essential for diagnosing anorectal melanoma [3].
- Colonoscopy: Colonoscopy combined with biopsy and subsequent pathological examination can accurately diagnose primary anorectal melanoma [4].
- Histopathological examination: Histopathological examination of tissue samples from the affected area can help confirm the diagnosis of malignant anal melanoma [5].
Other diagnostic tests
In addition to these tests, other procedures may be used to diagnose and stage malignant anal melanoma. These include:
- Physical exam: A comprehensive physical exam will include checking for signs of disease, such as lumps or anything else that seems unusual [6].
- Medical history: Your medical history and any previous diagnoses can also provide valuable information in diagnosing malignant anal melanoma [7].
It's essential to note that an early diagnosis of malignant anal melanoma can greatly improve the chances of successful therapy. If you suspect you have this condition, consult a healthcare professional for proper evaluation and treatment.

Treatment
Differential Diagnosis
The differential diagnosis of malignant anal melanoma can be challenging due to its rarity and nonspecific symptoms. According to various medical sources, the following conditions are often considered in the differential diagnosis:
- Hemorrhoids [4]
- Rectal polyps [2]
- Colorectal cancer [4]
- Anal fissures or fistulas [7]
- Chancroid or other sexually transmitted infections [7]
- Condyloma acuminatum (genital warts) [7]
- Neuroendocrine neoplasms, gastrointestinal stromal tumors (GIST), paragangliomas, and melanocytic nevi [9]
It's worth noting that the diagnosis of malignant anal melanoma is often delayed due to its rarity and nonspecific symptoms. A thorough medical history, physical examination, and diagnostic tests such as proctosigmoidoscopy may be necessary to establish a definitive diagnosis.
