Question
Primary site/Reportability--Breast: Is a “right nipple skin” biopsy that demonstrates squamous cell carcinoma reportable using a primary site of C500? See Discussion.



Discussion
In the 2011 SEER Manual Reportability Examples, example 3, it states a “biopsy-proven squamous cell carcinoma of the nipple” is reportable when the subsequent resection shows “no evidence of residual malignancy in the nipple epidermis.” However, this example does not specify the biopsy is from the nipple skin and the ICD-O-3 does not list nipple skin as a synonym for code C500.



Answer
Because the site is specifically stated to “skin” of nipple [C44.5], this case is not reportable.

If possible, you may wish to confirm the type of biopsy performed. If the biopsy was done by FNA or needle biopsy, the biopsy tissue should contain a full-thickness of skin and subcutaneous breast (nipple) tissue. If that is the case, this tumor would likely be a reportable squamous cell carcinoma of nipple [C50.0]. If, however, this was a punch biopsy it is more likely a non-reportable squamous cell carcinoma of the skin [C44.5].
