Question:
Reportability--Skin: Is an atypical smooth muscle cell proliferation of the skin reportable? See Discussion.
Discussion:
Example: Patient has left thigh skin excision with final diagnosis of atypical smooth muscle cell proliferation, inked peripheral margin is involved and inked deep margin is free of disease in the sections examined. See Comment.
Diagnosis comment states: The terminology regarding this lesion is controversial. Lesions with identical features are designated as leiomyosarcoma in the dermatopathology literature, whereas, the preferred classification in the soft tissue pathology is atypical intradermal smooth muscle neoplasm. Although the lesion appears predominantly dermal based, since the margin is involved, the lesion cannot be entirely evaluated, and therefore the final designation is deferred to the findings in the excisional specimen. (This slide was read by bone and soft tissue pathologist.)
There has been no excision of this tumor and, as a central registry, we have no access to the pathologist for clarification.
Is this skin case reportable based on the dermatopathology interpretation when further documentation is not available?
Answer:
Since you do not have the option of checking with the pathologist and no further information is available, do not report this case. The diagnosis is atypical smooth muscle cell proliferation of the skin, which is not reportable.
Registrars with access to the pathologist should querry the pathologist for clarification in this situation.
