Tiña inflamatoria: querion de Celso.

Tinea capitis is defined as an infection or parasitism of the hair, scalp, eyebrows, and eyelashes. The clinical presentation is variable, depending on the type of hair invasion, the level of resistance, and the degree of host inflammatory response. The most severe reaction pattern is known as kerion Celsi, caused mainly by zoophilic dermatophytes, Microsporum canis and Trichophyton tonsurans. It begins as a dry ringworm, which later presents with erythema, inflammation, pustules, and honey-colored crusts, from which abundant pus drains. Due to this clinical appearance, it takes the name kerion, which means "honeycomb". It can be associated with regional lymphadenopathy, fever, malaise, local pain, and often resolves, leaving an area of scarring alopecia. Early diagnosis and timely treatment are important to avoid these sequelae. [ABSTRACT FROM AUTHOR]
