Two adolescent boys presented with acute acneiform eruptions in the setting of recent dupilumab administration. Subsequent investigation via direct scraping pustules revealed live Demodex mite colonization face. These patients represent a population not commonly associated folliculitis, and we theorize their baseline commensal may have increased as consequence dupilumab-induced, focused immunom...

ated, he proposed that the life cycle of D. folliculorum mites was about 14.5 days. He also demonstrated that all life stages of these mites were negatively phototaxic, that is they were more mobile in a dark environment and relatively inert when bright light was shone on them. However, until optimal in vitro culture techniques and conditions allow Demodex proliferation in the laboratory, the t...

Demodex mites may induce inflammatory cutaneous reactions such as papulopustular rosacea and demodex folliculitis; both may lead to post inflammatory pigmentation. A 59-year-old man presented with an asymptomatic, hyperpigmented plaque on his face. Histological and clinical findings displayed Riehl-like facial pigmentation. Multiple demodex mites at the follicular infundibulum in the biopsy mat...

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...

BACKGROUND Granulomatous rosacea is a rare chronic inflammatory skin disease with an unknown origin. The role of Demodex follicularum in its pathogenesis is currently proved. CASE PRESENTATION We report a case of a 54-year-old Moroccan man with a 3-month history of erythematous, nonpruritic papules on the lateral side around the eyes. Dermoscopy and histology confirmed the diagnosis of granul...

The mite Demodexfolliculorum, which is currently evoking interest amongst ophthalmologists throughout the world, has been thoroughly described in detail by Coston (i967), Smith and McCulloch (I969), and English (I969). Mites and ticks, in contradistinction to the other arachnids have fused segments, giving a characteristic morphological appearance. Accordingly, the adult type of Demodex follicu...

Rosacea is a chronic inflammatory skin condition that predominantly affects the skin of the face and the eyes. Several factors are associated with the onset and persistence of the condition, including an altered immune response in the skin and elevated levels of Demodex mites. Alterations in the immune response include elevated levels of LL-37 in rosacea skin, increased expression of TLR-2 and ...

Demodex mites share a commensal relationship with humans, and they asymptomatically parasitize the pilosebaceous follicles of humans. In healthy skin, the density of the mites is normally low, and this low density does not cause skin diseases. When the density of these mites increases, they induce facial skin diseases. We describe a 27-year-old male who presented in our outpatient department wi...
