Hidden Agony: Foot Pain Linked to Pet Hair Splinter

Abstract

Cutaneous pili migrans is a rare and interesting dermatological condition characterized by embedding a hair or its fragment in the epidermis or superficial dermis, sometimes leading to pain and a serpiginous rash. We present a 28-year-old male who came to the clinic concerned about the sudden onset of pain in his foot over 10 hours. Upon meticulous physical examination, we found a white hair embedded in the skin of the fifth toe of his left foot, which the patient immediately recognized as hair from his dog. Upon removal of the hair, the pain immediately resolved. We believe our case represents the first reported case in Panama, the second in Latin America, and the second associated with dog hair. We anticipate that more cases related to animal hairs will be reported in the coming years due to the increasing popularity of pets in this century.
