Basal Cell Carcinoma
- most common of all skin cancers
- occurs in sun exposed areas, but only appear after many years, rarely metastasises; may present as a venous ulcer that cant heal
- most common area: face; danger areas: nose, ears eyes- Risk factors: sun exposure, radiotherapy, Gorlin’s syndrome
Types
nodular BCC
▪ Most common type on the face
▪ Small, shiny, skin coloured or pinkish lump
▪ Blood vessels cross its surface
▪ May have a central ulcer so its edges appear rolled
▪ Often bleeds spontaneously then seem to heal over
▪ Cystic BCC is soft, with jelly-like contents
▪ Rodent ulcer is an open sore
▪ Micronodular and microcystic types may infiltrate deeply

superficial BCC
▪ Tends to occur in younger patients
▪ Often multiple
▪ Upper trunk and shoulders, or anywhere
▪ Pink or red scaly irregular plaques
▪ Slowly grow over months or years
▪ Bleed or ulcerate easily
▪ Nodulocystic BCC may develop within superficial BCC

morphoeic BCC
▪ Also known as sclerosing BCC
▪ Usually found in mid-facial sites
▪ Skin-coloured, waxy, scar-like
▪ Prone to recur after treatment
▪ May infiltrate cutaneous nerves (perineural spread)
