It has been reported that Demodex mites play a role in the pathogenesis of rosacea, acne vulgaris, perioral dermatitis, seborrhoeic dermatitis, micropapular-pruritic dermatitis, and blepharitis. Methods used for diagnostic purposes included cyanoacrylic adhesives, comedone extractor, cellophane tape preparations, skin scraping, punch biopsy and standardized surface skin biopsy. This study is a retrospective work. The aim of the present retrospective study was the investigation of the incidence of Demodex mites using histopathological examination of skin biopsy specimens of keratinized cysts, fungal spores, tricholemmal cysts, nevi, dermatitis, fibrosis, carcinoma and inflammation of the scalp. Fifty-nine biopsy specimens were examined histologically after staining with hematoxylen-eosin. Demodex mites (i.e., tricholemmal cyst, dermatitis, sebaceous cyst, carcinoma, keratose cysts, nevi, fungal spores) were found in 9 (15.3%) of them. It was concluded that since this parasite is found in pathological cases of the scalp, the possible role of Demodex in the pathogenesis of such diseases should also be evaluated.

Is it acne or is it not? When this question arises, we can presume that we have crossed the boundaries of "acneiform eruptions" of the face. Although acne may be considered a condition fairly easy to diagnose, it is not rare for the practicing dermatologist or the general physician to wonder when faced with an acneiform eruption before establishing a diagnosis. In this review, we address facial acneiform eruptions in children and in adults, including perioral dermatitis, granulomatous periorificial dermatitis, nevus comedonicus, acne cosmetica, rosacea, demodicosis, folliculitis, acneiform presentation of cutaneous lymphomas, and drug-induced [epidermal growth factor receptor (EGFR) inhibitors, steroids, etc.] acneiform eruptions, along with their diagnosis and therapeutic approaches. The major distinguishing factor in acneiform eruptions is that, in contrast to acne, there are no comedones (whiteheads or blackheads).
