RESUMO
We report a case of a 41-year-old female with acrogeria. She was in good health except for the prominent atrophy over the hands and feet. On microscopic examination of a biopsy specimen from the atropl6c skin, elastic fibers were clumped and fragmented. Electronmicroscopy revealed amorphous and granulous pseudoelastin, which is presumed to be consistent with acrogeria. Our patient had acro-osteolysis and an extra chromosome in addition to the normal 23 pairs of chromosomes in one of 20 cells examined, which have been very rarely reported in the literature. Further studies are needed to find out whether this chromosomal aberration might contribute to the pathogenesis.

We report cases of two patients with acute generalized exanthematous pustulosis(AGEP). One patient had localized cutaneous infection and the other rhinoplasty. Both were being treated with ampicillin and developed intense erythemas followed by generalized subcorneal pustulation associated with fever and a neutrophilic leukocytosis. Histopathological findings were subcorneal spongiform pustules showing preponderance of polymorphonuclear leukocytes. Generalized pustular psoriasis, subcorneal pustular dermatosis, impetigo and pemphigus foliaceus should be differentiated from AGEP. The causative drug in both of our cases was ampicillin and fast resolution of pustules was observed with a low dosage of systemic steroid within 5 days.

Chronic dermatophyte infection rarely fails to respond to topical or systemic antifungal therapy. Such refractory condition relates to many factors and one of them is the decreased response of delayed type hypersensitivity. A plausible mechanism by which the delayed hypersensitivity response may cause dermatophyte inhibition has been proposed already. Our patient had skin rashes for 6 years. It was diagnosed as tinea corporis and treated with various systemic antifungal agents, such as griseofulvin, itraconazole, fluconazole, terbinafine and topical forms of econazole and terbinafine. But the skin lesions did not resolve completely and reaggravated frequently. Numerous verrucae planar were found on face, neck and both extremities. Trichophyton rubrum was identified by fungus culture study. Laboratory examination showed no response against multi-CMI test, DPCP sensitization and prick test for trichophytons. We challenged the therapy with the combined antifungal agents and immune stimulatory drugs. This case is thought to be a chronic dermatophyte infection due to the defects in the both cell mediated immunity and immediate type hypersensitivity which is crucial for the host defence mechanisms against fungal infection.
