A skin biopsy (most often a shave biopsy is sufficient) may be necessary to confirm the diagnosis and is often required to determine the histologic subtype of BCC. A punch biopsy may be used to obtain a thick specimen, especially when the clinical suspicion of a BCC is still present after shave biopsy results are negative. (See Workup.)
