Tinea capitis due to Microsporum canis in infants
Mycopathologia
|May 30, 1984
Abstract:
Three cases of scalp involvement by M. canis in infants are briefly reported. The first was a 2-month-old female with a few erythematous spots on the scalp, the second an 8-month-old male with lesions resembling seborrhoeic dermatitis and the third an 11-month-old male having areas of folliculitis of a kerion type. The father of the second case was found to have a tinea barbae infection due to the same fungus. Stray kittens were the most probable source of infection in all these cases.
Insights
Microsporum canis (M. canis) fungal infections can affect infant scalps, presenting as diverse lesions. Stray kittens are the likely source of these pediatric dermatophyte infections.
Area of Science:
- Dermatology
- Mycology
- Pediatrics
Background:
- Tinea capitis, a fungal infection of the scalp, is common in children.
- Microsporum canis (M. canis) is a significant zoophilic dermatophyte causing scalp infections.
- Early diagnosis and source identification are crucial for managing pediatric dermatophytosis.
Observation:
- Three infants presented with M. canis scalp infections.
- Lesions varied from erythematous spots to seborrhoeic dermatitis-like and kerion-type folliculitis.
- One infant's father had a co-existing tinea barbae due to M. canis.
Findings:
- M. canis was identified as the causative agent in all three infant cases.
- Clinical presentation of M. canis infections in infants can be diverse.
- Zoonotic transmission from stray kittens is the probable infection source.
Implications:
- Highlights the importance of considering M. canis in infant scalp lesions.
- Emphasizes the role of pets, particularly stray kittens, in pediatric dermatophyte transmission.
- Suggests the need for prompt investigation of potential animal reservoirs in pediatric tinea capitis cases.
