Squamous cell carcinoma of the urinary bladder
Diagnosis in short
LM DDx

metastatic squamous cell carcinoma (esp. squamous cell carcinoma of the uterine cervix), urothelial carcinoma with squamous differentiation,

condyloma acuminatum, squamous dysplasia
IHC p16 -ve/+ve
Site urinary bladder

Clinical history lived in areas with Schistosoma haematobium
Prevalence very rare

Squamous cell carcinoma of the urinary bladder, abbreviated SCC of the bladder, is a rare cancer of the urinary bladder.

Squamous differentiation in urothelial carcinoma is common and much more frequent than SCC of the bladder.

General

  • Strong association with Schistosoma haematobium.[1]
    • Common in areas with S. haematobium.
    • Uncommon in areas without S. haematobium.

Microscopic

Features:

DDx:

IHC

Features:

  • p16 -ve/+ve.
    • Not definite for separating from cervix - but suggestive: cervix ~86% +ve, bladder ~37% +ve.[2]
