"PILUS" (hair) and "Nidus" (nest) 1 designates the basic condition although many pilonidal cysts may not contain hair and any hair present may originate from an extrinsic source. [jamanetwork.com]

This complex variant of the disease may stem from prolonged neglect of symptoms but also occurs despite appropriate treatment. TREATMENT Treatment of pilonidal disease depends on the presentation. [ncbi.nlm.nih.gov]

[…] for surgical treatment is for the cyst to be surgically excised (along with pilonidal sinus tracts). [en.wikipedia.org]

Medical literature contains many articles on etiology, pathology, diagnosis, and treatment. Pilonidal disease, although first described by Anderson 2 in 1847, drew little attention for nearly 100 years. [jamanetwork.com]

The etiology of pilonidal disease as a foreign body reaction is supported by histological examination. [ncbi.nlm.nih.gov]

EPIDEMIOLOGY An incidence of 26 cases per 100,000 people was calculated by Sondenaa and others in a study of 322 patients with pilonidal disease. 5 It is, however, more common in young adult men, a population with an incidence of 1.1%. 6 Men are thought [ncbi.nlm.nih.gov]

To prevent recurrences in this series, the authors attempted to flatten the natal cleft by deepithelializing the medial end of the flap and folding it under itself to fill in the wound defect. [ncbi.nlm.nih.gov]
