<unk>  is a term used in dermatology to refer to "upward spreading" of melanocytes into the epidermis. It is uncommon and a possible indication of a precancerous or cancerous condition. Cells display<unk>  growth when they invade the upper epidermis from below. Squamous cell carcinoma, melanoma in situ,<unk>  Bowen disease and other carcinomas can all display<unk>  growth. A<unk>  growth pattern with upward growth of the melanocytes, so they are no longer confined to the basal layer, is considered pathognomonic for melanoma by some pathologists.
