Question


Histology--Penis: What is the histology code of a glans penis primary with the final diagnosis squamous cell carcinoma, verrucous type? See Discussion.



Discussion


Penile mass excision shows final diagnosis of squamous cell carcinoma, verrucous type. Subsequent partial penectomy has a final diagnosis of squamous cell carcinoma, verrucous type and the summary cancer data lists Histologic Type: Verrucous carcinoma.

Both the final diagnosis and summary cancer data indicate a histology code of 8051/3 (squamous cell carcinoma, verrucous type / verrucous carcinoma). However, this site and histology combination triggers edit IFN4911. Edit documentation indicates that for sites C600-C609 (all penile sites) use histology code 8051 and do not use 8054.

Review of the 2018 ICD-O-3 Histology Updates table does not indicate these terms are synonymous.



Answer


Code squamous cell carcinoma, verrucous type of the penis as verrucous carcinoma (8051/3).  In WHO Classification of Tumors of the Male Urinary System and Male Genital Organs, 4th edition, tumors of the penis, verrucous carcinoma is described as an extremely differentiated keratinizing papillomatous and acanthotic neoplasm; it accounts for 2-3% of penile squamous cell carcinomas.

The coding of condylomatous carcinoma and warty carcinoma changed from 8051/3 to 8054/3 in 2018 for penile sites only in the 2018 ICD-O-3 New Codes, Behaviors, and Terms-Updated 8/22/18.
