Summary
Perianal squamous cell carcinoma, even with superficial external sphincter involvement, can be successfully treated with surgical resection alone. This approach achieved a complete cure without recurrence or functional deficits one year post-surgery.
Area of Science:
- Oncology
- Surgical Oncology
- Gastroenterology
Background:
- Perianal squamous cell carcinoma (PSCC) is a rare malignancy often misdiagnosed.
- Standard treatment for early-stage PSCC (T1-T2, N0) typically avoids sphincter involvement.
Observation:
- A 45-year-old male presented with PSCC.
- Intraoperative findings revealed superficial external anal sphincter fiber involvement, contrary to initial imaging.
- A portion of the involved sphincter was excised for complete tumor removal.
Findings:
- The T2N0 perianal lesion was completely resected surgically.
- The patient experienced no recurrence or functional deficits one year after surgery.
Implications:
- Surgical resection may be a viable option for select PSCC cases with superficial sphincter involvement.
- This case challenges the strict contraindication of sphincter involvement in surgical management of PSCC.
- Further research can explore expanded surgical criteria for PSCC treatment.

01:25Assessment of the Rectum and Anus
671
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
