Question:
Reportability--Skin: Is a "basal cell carcinoma of the skin of the lip with focal skin appendage differentiation" reportable?
Discussion:
Answer:
The histology code for basal cell carcinoma with skin appendage differentiation is 8098/3. Basal cell carcinomas (8090-8110) are not reportable to SEER. Skin appendage tumors are not reportable to SEER unless stated to be carcinoma or stated to be malignant.
According to our pathologist consultant, basal cell carcinoma with focal skin appendage differentiation is basal cell carcinoma which exhibits adnexal (appendage) features, but it is still basal cell carcinoma.
The case example above is not reportable to SEER.
