Answer

Clinicopathologic types of BCC, each of which has a distinct biologic behavior, include the following:

  • Nodular: Cystic, pigmented, keratotic; the most common type of BCC; usually presents as a round, pearly, flesh-colored papule with telangiectases

  • Infiltrative: Tumor infiltrates the dermis in thin strands between collagen fibers, making tumor margins less clinically apparent

  • Micronodular: Not prone to ulceration; may appear yellow-white when stretched, is firm to the touch, and may have a seemingly well-defined border

  • Morpheaform: Appears as a white or yellow, waxy, sclerotic plaque that rarely ulcerates; is flat or slightly depressed, fibrotic, and firm

  • Superficial: Seen mostly on the upper trunk or shoulders; appears clinically as an erythematous, well-circumscribed patch or plaque, often with a whitish scale
