Interviews July 2009
Dr Belinda Welsh discusses the causes and clinical features of a variety of bullous skin rashes. Belinda discusses distinguishing features such as blister location, presence of mucosal involvement or whether the blisters are tense and intact (indicating dermal blistering) or fragile (indicating superficial blistering). Most presentations to GPs will be the result of infection, topical contact reaction, insect bites or drug reactions. However, if common conditions such as these are excluded, then often histology and immunofluoresence is required for diagnosis. (Belinda discussed the techniques for biopsy for both histology and immunofluorescence). Early referral to a dermatologist is recommended for Immunobullous disorders and serious non immunobullous diosorders such as porphyria cutanea tarda.

Skin and systemic disease
Dr Adriene Lee discusses the association between skin problems and systemic disease. Adrienne discusses skin conditions such as generalised pruritis, cutaneous vasculitis and erythema that may be an indicator of an underlying systemic condition; skin conditions that are much more rare but have an association with occult malignancy; and typical skin manifestations of connective tissue disorders.

Difficult to diagnose and aggressive BCCs
Dr Steven Tomas discusses the features and management of subtypes of BCCs that have a more aggressive course.‘Infiltrative’ , ‘micronodular’ and ‘morphoeic’ BCCs can infiltrate widely and deeply with relatively little change in the overlying skin surface. Assessing the margins of the lesion histologically can bedifficult increases the chance of incomplete resection and recurrence. Recurrent or residual disease is more difficult to treat, and itself has higher recurrence and incomplete removal rates. These tumours require carefully planned, aggressive treatment to cure.
