A. It must be excised with 1cm margins

B. Can be treated successfully with photodynamic therapy

C. Most often occurs on the scalp of men

D. Is a precursor of squamous carcinoma in situ

E. Most commonly affects the nipple

Question 42# In relation to basal cell carcinoma:
A. Metastasis never occurs
B. Is the most commonly occuring cancer of the lower lip
C. A 4mm margin on the face gives a cure rate of greater than 90%
D. Are never pigmented
E. Are familial in Gordon’s syndrome
A 4mm margin on the face gives a cure rate of greater than 90%. Metastasis is extremely rare, but reported. The commonest lower lip tumour is squamous carcinoma. Pigmented BCCs are a well-recognised subtype. BCCs are familial in Gorlin’s syndrome as an autosomal dominant trait, although up to a third are de novo mutations.

Can be treated successfully with photodynamic therapy. Photodynamic therapy consists of treatment with a photosensitizer such as 5- aminolevulinic acid, and the application of narrow wavelength light or a laser for activation and cellular destruction. It can be painful during photoactivation. It can be used on a range of malignant and premalignant skin conditions, especially actinic keratosis, Bowen’s disease (squamous carcinoma in situ) and BCC. The modality does not provide histopathological confirmation of clearance, but can yield cure rates in superficial lesions approaching those of surgical excision with excellent cosmesis. The commonest complication is hypopigmentation.
