Abstract
Aim: Pilonidal disease (PD) is a chronic inflammatory disease involving inverse recurrent suppuration, much like hidradenitis suppurativa (HS). The pathology of both conditions has been described as the follicular occlusion tetrade and share various common histological and immunohistochemical characteristics. The prevalence of HS in the general population is 2.10%.1 Studies using diverse cohorts provide estimates of PD in 4.6%–30% of patients with HS.
We aimed to find the prevalence of HS amongst patients with PD at our clinic.
Method: Using validated screening questions, we systematically screened all patients for HS when presenting with chronic PD in our clinic. HS patients were identified based on outbreaks of ‘boils’ during the last 6 months in predefined areas and further graded with a minimum of two boils giving a sensitivity of 90%, a specificity of 97% a positive predictive value of 96%.1,2
Results: A total of 191 patients (male 152) with pilonidal disease were screened. Of these 15 patients (7.8% [95% CI 4.6–12.3]) were found positive for HS (10 male). The lesions most frequently affected the groin (66.6% [95% CI 40.7–86.6]), the genitalia (53.3% [95% CI 28.6–76.8]) and the armpits (46% [95% CI 23.2–71.3]). Patient categories of PD and PD+HS were comparable in terms of gender distribution (p = 0.19), BMI (p = 0.18), smoking status (p = 0.21) and degree of pilosity (p = 0.58). PD+HS patients were, however, significantly older (28 years vs. 24, p = 0.016) than patients with PD alone, but with similar disease duration (36 months vs. 18 months, p = 0.11).
Conclusion: We found a higher prevalence of hidradenitis suppurativa in patients with pilonidal disease compared to the general population. Patients with PD+HS present later than the average pilonidal patient. Longitudinal studies are warranted.
