Acne solaris a form of acne that appears and relapses after sun exposure, is almost always itchy and is preferably localized on the upper anterior chest, the deltoid regions and the shoulders. The use of greasy or oily sun protectors helps in the obstructions of the follicular openings, which is seen in the tissue sections, presumably initiated by sun irradiation causing initially hyperkeratosis. The essential lesion is a small hemispheric or conic erythematous papule which may show a yellow point in its top. True comedos are not seen and compression after punction provokes the appearance of a yellow mass-essentially keratinic and sebaceous. The usual treatment of acne vulgaris is useful specially if a topical corticosteroid is associated. The systemic use of corticosteroids usually worsens the disease.

A single method to stain Malassezia furfur and Corynebacterium minutissimum in scales.

The scales are collected by pressing small pieces of scotch tape (about 4 cm length and 2 cm width) onto the lesions and following withdrawal the furfuraceous scales will remain on the glue side. These pieces are then immersed for some minutes in lactophenol-cotton blue stain. Following absorption of the stain the scales are washed in current water to remove the excess of blue stain, dried with filter paper, dehydrated via passage in two bottles containing absolute alcohol and then placed in xylene in a centrifugation tube. The xylene dissolves the scotch tape glue and the scales fall free in the tube. After centrifugation and decantation the scales concentrated on the bottom of the tube are collected with a platinum-loop, placed in Canada balsam on a microscopy slide and closed with a cover slip. The preparations are then ready to be submitted to microscopic examination. Other stains may also be used instead of lactophenol-cotton blue. This method is simple, easily performed, and offers good conditions to study these fungi as well as being useful for the diagnosis of the diseases that they cause.
