Anal squamous cell carcinoma is the most common type of anal cancer.[1]
It is also known as anal squamous carcinoma and squamous cell carcinoma of the anus.
General
- Most common form of anal cancer.[1]
- Overall anal cancer uncommon.[1]
- Strong association with HPV.[2]
Risk factors:[3]
- Men who have sex with men.
- Immunosuppressed.
- HIV infection.
Microscopic
Features:
Anus Squamous Cell Carcinoma (Non Keratinizing) - (SKB)
Anus Squamous Cell Carcinoma (Non Keratinizing) - (SKB)
Anus Squamous Cell Carcinoma (Non Keratinizing or shall we say poorly keratinizing as there are squamatized nests focally at high power) - (SKB)
DDx:
- Anal gland adenocarcinoma.
- Poorly differentiated rectal adenocarcinoma.
IHC
Sign out
RECTUM, DISTAL, BIOPSY: - INVASIVE SQUAMOUS CELL CARCINOMA.
