Superficial basal cell carcinoma of the scalp mimicking seborrhoeic dermatitis

Nonsyndromic giant basal cell carcinoma with follicular differentiation and multifocal localized basal cell carcinoma

Basal cell carcinoma is the most common malignant tumor of the skin. The most important feature is its very slow growth rate. It takes many years to reach gigantic dimensions. Various syndromes have been defined in which basal cell carcinoma exists in multiple localizations in a single patient. A case of basal cell carcinoma with multiple localizations and gigantic dimensions which is not classified as a syndrome is described in this case report.

Large superficial Basal cell carcinoma arising in the scalp

Superficial basal cell carcinoma (sBCC), a rare sub-type of basal cell carcinoma, can frequently occur in younger patients. This cancer type preferentially develops on the trunk. However, other subtypes of BCC can occur in the head and neck, probably secondary to sunlight exposure. Especially, sBCC on the scalp has been rarely-reported, accounting for 0.7~0.8% of all sBCC cases. We report a case of 71-year-old female with a large sBCC of the scalp, an unusual site of sBCC.
