Anorectal malignant melanoma is a malignant tumor that develops in the skin around the anal canal, and the disease is highly malignant with a low incidence.
Anorectal malignant melanoma is produced by a large number of melanocytes subjected to local stimulation or other metabolic abnormalities leading to carcinoma, which metastasizes early and has a very poor prognosis. In the clinic, blood in stool, even fresh blood, is often seen, because the disease often appears in the anorectal area of the mass, the mass grows rapidly, easy to bleed, and may be accompanied by obvious pain in the anal area or generalized fever and other symptoms.
Clinically, the diagnosis of anorectal malignant melanoma is often confirmed through rectal diagnosis and histologic examination of pathology, and surgical radical treatment can be taken under the guidance of doctors after early diagnosis.
It is recommended that people should pay attention to rectal diagnosis and anoscopy in routine physical examination, so as to better detect anorectal related diseases early and realize early detection, early diagnosis and early treatment.
