Skin Lesions

Multifocal Basal Cell Carcinoma

This lesion is deeply invasive and can be seen to extend beyond the border of the ulceration. This could also be classed as a multi-focal BCC; the difference is often not clinically apparent, and is only determined on histology.

Features

These lesions are usually of the nodular type, but display many focci of malignancy, as opposed to a solitary nodule in one region. See Figure 1. In practice, this type of BCC is often clinically indistinguishable from that of a Morphoeic/Sclerotic type BCC.
