Three patients with AIDS had an intensely pruritic eosinophilic pustular folliculitis associated with abundant Pityrosporum yeasts in the follicles, demonstrated by direct microscopy. The excellent response to ketoconazole treatment suggests a possible pathogenic role for Pityrosporum.
A sterile pustular skin eruption was observed in 17 of 3,541 newborn infants examined over a period of 30 months. The skin eruption was always present at birth and fulfilled the clinical criteria of transient neonatal pustular melanosis (TNPM). However, some days after birth, all of them but 1 developed skin lesions typical of erythema toxicum neonatorum (ETN). Histological examination of 11 biopsies obtained at the age of 1 day showed intracorneal neutrophilic pustules in 4 and subcorneal intraepidermic eosinophilic pustules in 7. On the basis of our findings and a literature review we consider that a clear-cut differentiation between TNPM and ETN is not always possible. We propose the name sterile transient neonatal pustulosis to unify these conditions.

We think that the incidence of this condition is higher than is reported. Because near all published cases had been published by the same authors who are familiarized and possess a high suspicion rate of this condition.

Two cases of sporothricosis originating from the same geographical area (Province of Barcelona) are described, including the circumstances of infection and the isolation of a wild strain of Sporothrix schenckii at the same locality. This finding could classify this particular area as a zone of interest in the epidemiological and ecological study of the mediterranean sporothricosis.
