Tinea capitis (TC) is a disease caused by dermatophytes of the skin of the scalp with a propensity for attacking hair shafts and follicles. It occurs predominantly in pre-pubertal children aged between 3 and 7 years. It is reported more in boys than in girls within pre-pubertal age. Tinea capitis is the most seen pediatric dermatophyte. The aim of this study was to assess the histopathological features of BCCs among patients irradiated for tinea capitis and correlate them with the clinical course. METHODS AND RESULTS: The medical records and BCC biopsy specimens of individuals who were previously irradiated for tinea capitis were reviewed Tinea Capitis In tinea capitis caused by ectothrix infection (Microsporum canis), the hyphae and spores cover the outside surface of the hair shaft, which results in destruction of the cuticle

The prevalence of tinea capitis in adults is around 10% i Histology of tinea capitis. The causative organism determines the pattern of hair invasion. Endothrix infections - There is minimal epidermal response aside from mild hyperkeratosis (figure 1). The hyphae extend within the hair shaft and produce spores (figures 2, 3). This form is caused by Trichophyton tonsurans/violaceum In all patients the diagnosis was based on anamnesis, clinical appearance and histopathology examination. Tinea capitis was confirmed by identification of fungal hyphae and spores in culture of hair roots and scalp skin scrapings.
