Pilonidal Cyst

The purpose of this registry is to collect real-world information on patients treated with Urinary Bladder Matrix (UBM) products. The study will evaluate patient characteristics, treatment patterns, and clinical outcomes to better understand how UBM products are used in routine clinical practice and the outcomes experienced by patients over time.

The goal of this randomized clinical trial is to test the topical drug clascoterone in patients with pilonidal disease, which is a common, benign skin condition of the gluteal cleft. The main questions it aims to answer are: * Does clascoterone improve the severity of pilonidal disease as scored by a physician? * Does clascoterone improve patient symptoms due to pilonidal disease? * Does clascoterone improve the inflammation seen under the microscope in pilonidal disease removed at surgery Participants will apply clascoterone or a placebo cream to the diseased area for 3 months. They will be assessed every 4 weeks for disease severity assessed by a physician viewing patient photos and a symptom-based survey. Researchers will compare participants who received clascoterone treatment to those who received placebo.

The goal of this observational study is to describe the impact of recurrence on the quality of life of patients treated with radical surgery and laser therapy. The secondary objective is to describe in patients treated with radical surgery and laser treatment : * Intensity of pain and discomfort * Duration of nursing care since surgery * Duration of inactivity since intervention
