sudoriferous (glands)
sweat glands; located in epidermis; secretes sweat
Tic douloureux

LESION: papule
solid or cystic raised spot on the skin that is less than 1cm in diameter (mosquito bite)

SKIN CANCER: basal cell carcinoma
Most common skin cancer, and the least dangerous bc does not metastasize. The bottom layer of the epidermis is the basal cell layer, and cells in this layer are the ones that become cancerous. Most basal cell cancers occur on skin that is regularly exposed to sunlight or other ultraviolet radiation.
SKIN CANCER: squamous cell carcinoma
Responds well to surgical removal but can metastasize to lymph glands if neglected. Squamous cell carcinoma is an uncontrolled growth of abmornal cells arising in the squamous cells, which compose most of the skin’s upper layers.
SKIN CANCER: malignant melanoma
Least common skin cancer, but the most deadly. Metastasizes quickly and is fatal if neglected. These cancerous growths develop when unrepaired DNA damage to skin cells (most often caused by ultraviolet radiation from sunshine or tanning beds) triggers mutations that lead the skin cells to multiply rapidly and form malignant tumors. The tumors originate in the pigment-producing melanocytes in the basal layer of the epidermis.
