A 7-year-old child from a rural area had long time contact with domestic animals presented with a boggy mass on the occipital scalp of one month duration. The mass was tender, crusted, studded with many pustules and associated with hair loss and suboccipital lymph nodes enlargement.
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. The following features are good clues to the diagnosis of impetigo contagiosum which commonly occurs in children:
A 17-year-old girl presented with brownish dirty warty papules of wide distribution on the axillae, trunk and neck of many years duration. Skin biopsy was consistent with Darier’s disease. Family history of similar condition was negative.
A 28-year-old man presented with an asymptomatic, solitary, firm, pink- brownish, dome-shaped nodule on the dorsum of the hand of many months duration.
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.
A 25-year-old man suffered skin whealing on friction, rubbing or stroking. The wheals last about 15-20 minutes and disappear. The presented photo shows classical linear wheals induced at consultation room by a blunt object.
A case of Darier’s disease diagnosed since 15 years ago. On examination a characteristic nail dystrophy was found in form of longitudinal white lines and longitudinal ridges of the nail plate run over the lunula to the free margin of the nail and end with triangular nicks in addition to subungual debris.
