Question
MP/H Rules/Histology--Skin: How is the histology coded for “infiltrative carcinoma with ductal alterations compatible with squamoid eccrine ductal carcinoma” of the skin?

Discussion


Answer
Code the histology to 8413/3 [eccrine adenocarcinoma]. This is the most specific code available for this diagnosis.

According to our expert pathologist advisor, “The adnexal glands in the skin, sweat (eccrine) glands and apocrine glands, all have ducts which connect the business portion of each gland to the skin surface. Some of the adnexal tumors have features of differentiation which appear to be duct-like, hence the designation 'ductal.'"

In addition, "The 'squamoid' simply indicates some degree of squamous differentiation, but doesn't alter the usefulness of [code 8413/3] because we have no way of coding anything more specific in this case anyway."
