Accessory Structures of the Skin: Hair Growth and Types

Accessory Structures of the Skin: Hair Growth and Types

Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Accessory Structures of the Skin: Hair and Hair Follicles

Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Summary

A severe fungal infection of the scalp, Kerion celsi, in a child was successfully treated. This case highlights the zoonotic transmission of Trichophyton mentagrophytes from pet guinea pigs, a common source of dermatophytosis.

Area of Science:

Mycology
Dermatology
Zoonotic Diseases

Background:

Dermatophytoses are superficial fungal infections impacting skin and appendages.
Tinea capitis, a fungal infection of the scalp, can manifest severely as Kerion celsi.
Zoonotic transmission of dermatophytes from animals to humans is a significant public health concern.

Observation:

A clinical case report details a 7-year-old girl presenting with Kerion celsi.
The patient exhibited painful, edematous, crusty scalp lesions and alopecia.
Samples from the patient's scalp and mother's arm revealed Trichophyton mentagrophytes.

Findings:

The patient's infection was diagnosed as Kerion celsi, a severe form of Tinea capitis.
Cultures confirmed Trichophyton mentagrophytes in both the patient and her mother.
The family's pet guinea pig was identified as the likely source of infection.

Implications:

This case underscores the importance of considering zoonotic sources, specifically pet guinea pigs, in pediatric dermatophytosis.
Prompt diagnosis and appropriate treatment, including surgical intervention and antifungal therapy, are crucial for managing severe Tinea capitis.
Public health awareness regarding the prevalence of Trichophyton mentagrophytes in guinea pigs and its transmission potential is essential.
