Journal Title: Scholars Journal of Medical Case Reports - Year 2015, Vol 3, Issue 9
Abstract
Demodex is a common commensal mite of the pilosebaceous unit in human and animal (mammals). Alopecia is a loss of hair from the head or body and there are many type of hair loss with different symptoms and causes. This is a case report of a 30-year-old woman with hairless area in head. She had no families’ history of alopecia or autoimmune disease. There was no significant improvement after 1 year routine treatment for her alopecia. She had a domestic pet (Hamster) and she announced that her hamster has slept in her bedroom (her bed). We taken scales from hairless area and examined it under microscope and the hamster skin was also examined. In microscopic direct examination of her scalp observed many demodex in two species D. folliculorum and D. cricetuli and only D. cricetuli in her hamster. She was treated for demodexis and after about 2 months her hair re grown. The some common symptoms of demodicosis are: redness of skin, itch, loss of eyelashes and eyebrows. Demodexis may play a pathogenic role when they are in large numbers, or there is an immune suppression. In present case after a long time treatment by local and systemic corticosteroid therapy immune suppression was acquired and the hairless area developed. Therefore we can conclude the demodex cause to hairless in some condition. In some studies loss of eyelashes and eyebrows were reported due to demodex but there is any report about scalp hair loss. So this patient is a specific case of demodexis. Keywords: Demodex, pilosebaceous, aleopcia.
