Criteria for its diagnosis are presented and its nonsclerotic nature emphasized. Analysis of 174 consecutive BCCs referred for Mohs micrographic surgery showed the infiltrative subtype (29 tumors) to be significantly more destructive and difficult to treat than the more common nodular BCC. © Lippincott-Raven Publishers.
