Clinical guide
Full biopsy guidance in a concise, scannable format.
There are several dermatological presentations and considerations that warrant biopsy sampling. Some of the most common include:
When cancer-neoplasia is suspected (clinical lesions with obvious growths, nodules, chronic proliferative or ulcerative lesions).
When lesions are acute and severe and/or where drug reactions or autoimmune diseases are suspected (widespread or mucocutaneous erosive or ulcerative lesions).
When lesions fail to respond or progress in the face of appropriate therapy.
When therapy can be associated with higher incidence of adverse reactions and expense.
