Seventy patients with a clinical diagnosis of Malassezia folliculitis were studied, of which 48 were confirmed on finding unipolar budding yeastlike organisms on gramstained microscopy or histology specimens. The epidemiologic and clinical features of these 48 cases (M = 44; F = 4) were analyzed. The typical Singaporean patient with Malassezia folliculitis is a young man of mean age 22.2 years with erythematous follicular papules or pustules on the upper back, shoulders, upper chest, and sides of the back. Aggravating factors include heat and sweating. Excessive sebum production may be an important underlying factor.

Summary Fifty‐seven patients with a Dry, Glazed, Erythematous, Fissured, non‐pruritic or mildly pruritic palmar dermatitis are described. This condition was provisionally called dermatitis palmaris sicca. It appears unrelated to an allergic or irritant contact Dermatitis, and endogenous factors like Atopy, Xerosis, inherited susceptibility and Hormones, together with exogenous Factors, like Friction, and repeated hydration and Dessication, may be important to its aetiology. It runs a chronic course interrupted by episodes of painful fissuring. Exudation and Weeping, typical of other forms of hand Dermatitis, arc usually not seen. The histology shows features of a psoriasiform dermatitis. Response to topical corticosteroids is Poor, and simple emollients are useful For reducing its tendency to fissure. A close relationship to finger‐tip Eczema, dyskeratotic eczema and juvenile plantar dermatosis (or dermatitis plantaris sicca) is postulated.
