Background: Tinea capitis (TC) is a common dermatophyte infection of the scalp that can also involve the eyebrows and eyelashes.
Aim: This study aimed to find the causative fungus responsible for TC in Botswana and determine its association with the clinical types of TC.
Methods: Samples for potassium hydroxide 10% mounts and fungal cultures were collected in a microbiology laboratory at the National Health Laboratory, Gaborone, Botswana. Dermasel agar and Sabouraud dextrose agar were inoculated with the samples. Lactophenol cotton blue mounts were prepared from the culture-positive samples to study the morphological characteristics.
Results: Trichophyton violaceum was found to be the predominant causative organism of TC. Trichophyton tonsurans was isolated from one patient. Both are anthropophilic species.
Conclusion: TC was found to be most common in those aged 1-15 years (81%). Of 17 patients in this age group, 16 were younger than 10 years old and one was 14 years old. T. violaceum was the most common dermatophyte species isolated.

Objectives: This study aimed to determine the prevalence, clinical, and epidemiological features of tinea capitis (TC) in schoolchildren in Mahajanga city, north-west Madagascar, to identify the etiological dermatophyte species by morphological, proteomic and molecular approaches and ultimately to analyze the risk factors promoting TC in the studied region.
Methods: A survey was conducted in a randomly selected primary school. Symptomatic schoolchildren with signs resembling TC were sampled by scraping and sterile swabbing after examination of the scalp with a Wood's lamp.

Background: Dermatophytosis caused by Nannizzia gypsea are considered rare. The clinical picture is indistinguishable from that produced by other dermatophytes, but, being this a geophilic fungus, it can cause more inflammatory disease.
Methods: Retrospective study.

Introduction: Although the diagnosis of tinea capitis is mainly microbiological, the risk of evolution towards cicatricial alopecia in the most severe cases requires empirical treatment based on physical examination and complementary examinations.
Methods: Two patients were evaluated by physical examination, cutaneous ultrasound and microbiological examination.
Results: Ultrasound showed follicular widening and increased vascularization in Doppler mode.

Objectives: Tinea capitis remains a common fungal infection in children worldwide. Species identification is critical for determining the source of infection and reducing transmission. In conventional methods, macro- and microscopic analysis is time-consuming and results in slow fungal growth or low specificity.

Background: Although cutaneous mycoses are a global public health problem, very few data are available in the Democratic Republic of Congo (DRC).
Objectives: This study aimed to describe the retrospective clinical epidemiology of dermatomycosis and their associated risk factors in dermatological consultations in Kinshasa, DRC.
Methods: A retrospective study based on the medical records of patients seen in the departments of dermatology of 2 major hospitals in Kinshasa from March 2000 to August 2023 was carried out.
