Overview

Case report reveals recurrence of chest wall abscess misdiagnosed as sebaceous cyst, suggesting careful diagnosis is essential.

Key Points

  • To present a case of an anterior chest wall pilonidal sinus misdiagnosed as a recurrent abscess and discuss diagnostic challenges.
  • Reported a 24-year-old man with a 3-year history of a recurrent chest wall lesion.
  • Utilized MRI and CT to assess the lesion, followed by surgical debridement and histopathological examination.
  • Conducted a nearly two-year follow-up to monitor healing and recurrence.
  • Confirmed diagnosis of pilonidal sinus with a robust foreign body giant cell reaction and chronic inflammation on histopathology.
  • After complete resection, smooth healing was observed during follow-up, with no recurrence reported.
