There are many unusual lesions of the anus, perianal area and some other organs around the proctos included.
Some local anal lesions, mainly post-operative complications, are difficult to treat. often unusual anal lesions are associated with general diseases, not easily cured.
First, we should study unusual and rare anal lesions, and second we must keep in mind to rule out some related lesions as specific infection, non-specific inflammatory bowel diseases and malignant or benign tumors.
I chose to present some lesions with my comments about diagnosis, how I do it, and care points.
1) A plastic surgical approach for a complexed proctos with combined lesions of usual hemorrhoidal syndrome.
2) Two cases of anal cloacogenic carcinoma with usual anal complaints.
3) Pruritus ani and some dermal lesions, malignant included.
4) Impaled trauma of the anus on an iron bar.
5) Reduction of incarcerated rectal prolapse.
6) Mucosal prolapse syndrome, acute hemorrhagic rectal ulcer, rectal cancer with peri-proctal abscess, perianal fistulae of tuberculosis, anal stricture and ulcer due to Crohn's disease.
7) Massive bleeding after usual hemorrhoidectomy of a patient with hemophilia A, anal symptoms owing to orthopedics, and a case of rectal leiomyosarcoma.
