BACKGROUND: Skin picking disorder (SPD) is classified as a primary psychodermatologic disorder, in which lesions are self-induced. It is frequently encountered by dermatologists, but the management is still a source of discomfort for the majority.
OBJECTIVES: The first objective is to determine the characteristics of the SPD patients in our centre: the demographics, the psychiatric comorbidities, clinical and histopathological characteristics of SPD patients, treatments and follow-up. The second objective is to demonstrate the need for education in the dermatologic community.
METHODS: We retrieved and described cases of SPD from January 2011 to December 2022. All inpatients were evaluated at the Centre Hospitalier Universitaire de Québec - Université Laval. Qualitative and quantitative data on SPD were collected.
RESULTS: The sample comprised 83 patients, with a mean age of 62 years, and a bimodal distribution. 63.8% were female and lesions were most frequently described as excoriations (27%). Physicians observed picking from multiple body sites, the most common being upper extremities. Only 11% of patients were biopsied. Psychiatric comorbidities were frequent, especially personality traits and disorders (19.2%), and substance-related and addictive disorders (16.8%). Wide variety of treatments were prescribed, including local and supportive care. Only 41% of the sample had medical follow-ups.
CONCLUSIONS: This large-scale retrospective assessment of patients diagnosed with SPD broadens the scope of a frequent disorder in dermatology, showing older age patients, unexpected psychiatric comorbidities and inadequate continuity of care. Results highlight the need for a collaborative approach and for frequent reassessments of these patients.
