Discoid Lupus Erythematosus leading to Squamous Cell Carcinoma.

DLE/CCLE is a benign disorder of skin, most frequently involving face and characterised by well defined , red scaly patches of variable size which heal with atrophy, scarring & pigmentary changes. The histology is characteristic. Squamous cell carcinoma and less commonly basal cell carcinoma occasionally occur in scars of DLE particularly over scalp,ears.lips & nose. In one study by Millard et al the incidence was 3.3% among 120 white patients with CCLE We report a case of squamous cell carcinoma (SCC) developing over lesions of disseminated DLE other than scalp and lip in an Indian patient. A 40-year-old male patient came with a large erythematous ulcerated plaque over dorsum of left foot of size 5cm x 4 cm in size , over it he had 56 cauliflower like masses. Histopathological examination showed presence of keratin pearls suggestive of squamous cell carcinoma.
