## Abstract

This case highlights the importance of thorough clinical examinations from head to toe and the early diagnosis of trichilemmal cysts. We present a case of an incidentally discovered trichilemmal cyst in a 72-year-old patient who presented with acute kidney injury secondary to a urinary tract infection. In rare instances, these cysts can transform into malignant lesions. Therefore, clinicians should be aware of the potential for malignancy when diagnosing and managing trichilemmal cysts.
