Endothrix
Endothrix
Endothrix (pronunciation: en-doh-thriks) is a term used in the field of dermatology and mycology to describe a type of fungal infection where the fungus grows within the hair shaft.
Etymology
The term 'Endothrix' is derived from the Greek words 'endo', meaning 'within', and 'thrix', meaning 'hair'.
Definition
Endothrix is a type of dermatophytosis, specifically a tinea capitis, where the fungal infection is characterized by the growth of the fungus inside the hair shaft. This is in contrast to Ectothrix, where the fungus grows on the outside of the hair shaft.
Symptoms
The symptoms of an Endothrix infection can include alopecia, scaling, and inflammation of the scalp. In severe cases, it can lead to kerion, a painful inflammatory reaction.
Diagnosis
Diagnosis of Endothrix is typically made through a combination of clinical examination and laboratory testing. The Wood's lamp examination may not be helpful as the infected hairs do not fluoresce. Microscopic examination of the infected hairs can reveal the presence of the fungus inside the hair shaft.
Treatment
Treatment of Endothrix typically involves the use of oral antifungal medications, such as griseofulvin or terbinafine. Topical antifungal treatments are generally not effective as they cannot penetrate the hair shaft to reach the fungus.
