Question:
Reportability--Skin: Is this reportable? If so, what is the correct histology code? The pathology report says, " bx of 0.7 x 0.5 cm gray-pink papule on tan-pink skin of left inferior centra malar cheek revealed invasive SCC of skin, signet ring cell type, invading papillary dermis; LVI neg; "findings are diag of SCC exhibiting the rare signet ring histologic subtype"; deep margin positive for tumor but peripheral margins clear;".
Discussion:
Answer:
SCC of skin, signet ring cell type, is not reportable to SEER. SCC's of skin classifiable to 8050-8084 are not reportable to SEER. See page 11 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf
Signet ring is a rare histological variant of SCC and is coded to 8070/3 according to the WHO classification for skin tumors.
