Tinea capitis with kerion complicated by keloid formation in a 34-year-old man: A case report

A kerion, also known as a dermatophyte, is a type of inflammatory tinea capitis caused by an exaggerated immune response to a fungal ringworm infection primarily affecting the scalp. A keloid is an abnormal scar tissue proliferation occurring at the site of tissue injury or spontaneously. It occurs more commonly in darker-skinned individuals. The coexistence of kerion and keloid is rare. This case involves a 34-year-old man who presented with a four-year history of scalp swelling, itching, and occasional fluid discharge. There is a history of keloids in multiple parts of the body. Examination revealed multiple keloids on the scalp alongside a purulent, oozing rash with satellite nodules. Skin scraping for KOH microscopy was positive for fungal spores and hyphae. This case highlights the rare complication of keloid formation in kerion which can hinder effective treatment of the underlying fungal infection.
