ABSTRACT
Abstract: The aim of the study was to identify Bacillus species from the Demodex folliculorum of patients with topical steroidinduced facial rosaceiform dermatitis. Of the 75 patients examined, 20% had clinical spinulosis, while 18.66% had dermoscopic features of Demodex: follicular plugs and tails. Of the 17.33% positive patients identified upon microscopy for Demodex, samples for bacterial culture were plated on trypticase soy Colombia agar. Identification was performed by microorganisms grown method mass spectrometry. We identified a strain of Bacillus cereus.

Background: Rosacea fulminans is a rare condition, characterized by a sudden onset of papulopustules, cysts, edema, and draining sinuses usually confined to the facial area. It is often accompanied by low-grade fever, myalgias and leukocytosis. Patients usually have a background of mild rosacea. We report two male patients aged 29 and 54 years, presenting with rosacea fulminans and ocular involvement, triggered by the use of topical steroids. Both responded to systemic treatment with corticosteroids, isotretinoin and metronidazole. Rosacea fulminans should be considered as a variant of rosacea that includes papulopustular, ocular, phymatous and erythematotelangiectatic types.
