Tell me about basal cell carcinoma using DEPSIM?
(description, epidemiology, pathophysiology, symptoms, investigation, management).
- skin cancer
- most common
- effects deepest cell layer of the epidermis.
- 90% present on the head and neck. 'pearly' papule with overlying telangiectasia. central ulceration, raised border. non-healing lesion that bleeds easily.
- shave or punch biopsy or full excision if ulcerated to investigate.
- Managed with surgical excision.
prognosis: these rarely metastase and invasion is local. carcinoma on nose more likely to spread.
