Kerion celsi
A rare inflammatory and suppurating type of tinea capitis, a skin infection caused by Trichophyton or Microsporum fungi, that predominantly affects the scalp and that is characterized by the development of painful crusty lesions covered with follicular pustules and surrounded by erythematous alopecic areas, that can later evolve into abscesses and leave permanent cicatricial alopecia. Lesions can be associated with regional lymphadenopathy.
