Popis: Psoriasis of the external auditory canal (PsEAC) is often under-recognized. The aims of this study were to assess the prevalence of PsEAC, its association with a particular psoriasis subtype and its impact on quality of life (QoL). A prospective study was carried out in two Spanish university hospitals, enrolling consecutive patients who attended a consultation for psoriasis. The clinical features of psoriasis and PsEAC were recorded and the Dermatology Life Quality Index (DLQI) and Itch Numerical Rating Scale (Itch-NRS) were distributed to patients. Overall, 188 of 1000 patients (18.8%) included in the study had PsEAC, which was associated with severity of psoriasis, presence of inverse psoriasis and involvement of the scalp, nails and genitals, but not with obesity or psoriatic arthritis. PsEAC was the main reason for consultation in 27 patients, with itching being the main symptom. In this study, PsEAC had a prevalence of 18.8%. The occurrence of PsEAC was associated with poorer QoL, as measured by DLQI and Itch-NRS.
