Sažetak
Moniletrix is an uncommon genodermatosis characterized by hair shaft structure alterations that show a periodic variation in thickness and result in hair fragility and alopecia. The disease is transmitted in an autosomic dominant pattern, with high penetrance, variable expression and seems to be caused by mutation of a gene on chromosome 12q. A23-year-old male patient is described who presented from infancy hair problems and went bald in his teens. The disease started in the first year of life. The mother noted that his hair was fine, brittle and sparse. On examination of the scalp the hair was light brown, 6-10 mm in length, thin, dray and fractured easily. The skin of the vortex on palpation resulted rough with follicular papules. Similar papules were present on the elbows and knees. The eyebrows were thinned laterally, while axillary and pubic hair was also sparse. The general condition of the patient was good, and laboratory investigations were normal. Standard light microscopic examination of the hair showed a more or less regular variation in shift thickness. Family history revealed absence of consanguinity, but the patient mother had similar hair structure alterations. Biopsy of the patients scalp revealed a normal epidermis with normal follicles and no reduction of the sebaceous and sweat glands. The differential diagnosis includes pseudomonilethrix and other shaft abnormality which may be sporadic or inherited. Many drugs were administered without valuable improvement. At present the patient is taking etretinate and a mild amelioration is visible.
