A 62-year-old woman had been diagnosed as BCC of the scalp 3 years ago treated with curettage and cautery at that time. After 2 years of treatment a new ulcer appeared at the site of previous treatment and within one year a rodent ulcer with a rolled up irregular border of about 7 cm diameter was established. Incisional biopsy proved ulcerative BCC.
A 52-year-old man complained a very itchy skin lesion on the front of the ankle of his left foot. The itching was paroxysmal and severe. On examination, there was a well-defined, thickened and hyperpigmented large plaque with exaggerated skin lines spreading across the front of the ankle region.

This 2-year-old baby presented with multiple erythematous patches covered with yellow crusts that spread quickly within 3 days to involve the periorificial areas around the mouth and nose.

This 32-year-old woman presented with multiple red painful and tender nodules on both legs of two weeks duration. The lesions were distributed bilaterally and symmetrically on both shins. It was the first episode suffered by the patient. She had no systemic symptoms and no associated condition that may predispose to erythema nodosum.
This 20-year-old female presented with asymptomatic whitish plaques covered the entire dorsal surface of the tongue of many months duration associated with multiple transverse fissures radiating from a longitudinal central deeper groove of many years duration.There was no associated systemic disease.
