MRCP revision battle 50.3: Seborrhoeic dermatitis

Seborrhoeic dermatitis, AKA seborrhoeic eczema, is a skin condition characterised by dandruff and sometimes dry, erythematous flakey skin.

It is associated with a fungus called Malassezia furfur (previously known as Pityrosporum ovale).  However, it is not contagious.

Treatment is with ketoconazole 2% shampoo and anti-fungal cream.

Severe forms of seborrhoeic dermatitis are associated with Parkinson's disease and HIV.

Complications include otitis externa and blepharitis.

Now for some hair loss...
