Volatile alkyl nitrites, colloquially known as "poppers," are commonly inhaled by men who have sex with men (MSM) for their psychoactive and muscle-relaxing effects. They have been reported to cause either allergic contact Dermatitis® (ACD) or irritant contact Dermatitis® (ICD), termed "poppers Dermatitis®." We searched PubMed, Embase, and Web of Science to understand the patient population, clinical presentation, diagnosis, and clinical course of poppers Dermatitis®. Our search returned 13 articles detailing 18 patients total. Most patient cases were male (n = 13/15; 87%), of whom 5 were MSM. The reports on the remaining 8 men did not disclose their sexual behaviors. The chemicals deemed responsible for adverse cutaneous side effects included amyl nitrite (6/18; 33%), butyl nitrite (3/18; 167%), isobutyl nitrite (2/18; 11%), and an unspecified alkyl nitrite (7/18, 39%). The most common diagnosis was ICD (10/18; 56%). Only 3 patients underwent alkyl nitrite patch testing, with 2 testing positive for ACD. The most commonly involved anatomic sites were perinasal (13/18; 72%) and perioral regions (10/18; 56%). Rash morphology has been described as yellow crusting, impetigo-like, eczematous, vesicular, edematous, and erythematous. Ulceration can occur with direct skin contact to concentrated nitrite solution. Poppers Dermatitis® was often self-limited with complete resolution. Dermatologists should consider poppers Dermatitis® in those presenting with a characteristic midfacial rash, especially in MSM.
