See discussion. Discussion The 2011 SEER Manual Reportability Examples (example 3) 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 Since the site is specifically stated to be "skin" of nipple, 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 full-thickness of skin and subcutaneous breast (nipple) tissue, and this tumor would likely be a reportable squamous cell ca of nipple (C500). If, however, this was a punch biopsy, it is more likely a non-reportable skin cancer.
