scarring baldness
Last reviewed 01/2018
Scarring alopecia is characterised by follicular destruction and replacement of the interfollicular epidermis by atrophic skin.
Most common dermatoses which cause scarring:
- chronic discoid lupus erythematosus
- lichen planus
- lichen sclerosus
- localised scleroderma - morphoea
Others:
- neoplasms - basal cell carcinoma, squamous cell carcinoma, adnexal (arising from the hair follicles) and metastatic (eg. breast)
- infections - fungal eg. Tinea capitis; bacterial eg. staphylococcal folliculitis
- mechanical trauma, burns, exposure to chemicals, irradiation
- developmental defects - aplasia cutis, epidermal naevi, epidermolysis bullae, Darier's disease
