Pilonidal disease and hidradenitis.

Pilonidal disease and hidradenitis suppurativa are common problems that affect young adults. The surgical management of pilonidal disease should be tailored to the individual clinical presentation and its goal is the resolution of pilonidal disease with low recurrence and low morbidity. The clinical course of hidradenitis suppurativa is characterized by chronicity with frequent flare-ups followed by quiescent periods. Treatment for both conditions needs to be individualized to the clinical presentation.
