Establishing an Association between Polycystic Ovarian Syndrome and Pilonidal Disease in Adolescent Females

Study Objective: We sought to determine whether pilonidal disease (PD) is associated with polycystic ovarian syndrome (PCOS) in adoles-cent females.Design: Retrospective cohort studySetting: Urban tertiary children's hospitalParticipants: All girls aged 12 to 21 who received a diagnosis of PD and/or PCOS from 2012 to 2019Interventions: Treatment for PCOS and PD Main Outcome Measures: The variables analyzed included age, race/ethnicity, body mass index, age at menarche, tobacco use, payer status, treatment of PCOS and PD, and serum markers of hyperandrogenism and metabolic syndrome.Results: During the study period, 100,043 patients presented to an urban tertiary medical center. Of these patients, 966 were diagnosed with PD, and 219 were diagnosed with both PD and PCOS. Compared with patients with only PD, patients with both diagnoses had a higher body mass index (31.4 vs 27.4 kg/m2; P < .01) and were older (18.76 vs 18.30 years ; P = .003). The prevalence ratio for patients with PD having PCOS per the original Rotterdam criteria was 26.1 (CI, 22.0-31.0) and 28.7 (CI, 24.3-33.9) for having PCOS per the modified Rotterdam criteria. Patients with both diagnoses were less likely to receive intervention for PD (OR = 0.22; CI, 0.13-0.37; P < .001).Conclusions: Adolescent females diagnosed with PD are likely to demonstrate features of PCOS. PCOS treatment could positively alter the disease course of PD. As such, surgical providers should consider referring adolescent females with PD to endocrinologists, gynecologists, and adolescent medicine specialists for evaluation of PCOS.
