Trichophyton violaceum remains the most common etiological agent of adult TC in Tunisia. Microsporum canis is rising rapidly most notably due to the high frequency of asymptomatic carriage by domestic animals [corrected].

The objective was to determine the demographic characteristics, the clinical features, the immuno-histological findings and response to treatment of childhood linear IgA bullous dermatosis (LABD) in Tunisia. We collected all the cases of auto-immune bullous diseases of childhood, diagnosed from January 1987 to December 2006. Based on clinical, histological, and immunofluorescent features, we identified 25 cases of LABD. Sixteen male and nine female children with a mean age of 7.5 years were identified. Clinical manifestations were characterized by a vesiculo-bullous eruption in all cases associated with mucous membrane involvement in two cases. Dapsone was the main therapy in 19 cases, associated with systemic corticosteroids in eight cases. Exclusive antibiotic therapy was successful in five cases. Sixteen of those patients had resolution of disease after a mean period of 15 months and eight patients had severe clinical presentation and required a prolonged follow-up. Childhood LABD is the most frequent bullous dermatosis in Tunisia. The majority of our patients responded rapidly to dapsone treatment and were stabilized for long time. Our cases were characterized by a minimal mucosal involvement and favorable outcome. Treatment with antibiotherapy was interesting. Erythromycin and oxacillin may be considered as an alternative therapy.

Clinicians should be aware of the ability of captopril to induce LPP.

Acetaminophen is a widely used analgesic drug. Its adverse reactions are rare but severe. An 89-year-old man developed an indurated edematous and erythematous plaque on his left arm 1 day after acetaminophen ingestion. Cellulitis was suspected and antibiotictherapy was started but there was no improvement of the rash; there was a spectacular extension of the lesion with occurrence of flaccid vesicles and blisters in the affected sites. The diagnosis of generalized-bullous-fixed drug eruption induced by acetaminophen was considered especially with a reported history of a previous milder reaction occurring in the same site. Acetaminophen was withdrawn and the rash improved significantly. According to the Naranjo probability scale, the eruption experienced by the patient was probably due to acetaminophen. Clinicians should be aware of the ability of acetaminophen to induce fixed drug eruption that may clinically take several aspects and may be misdiagnosed.
