Pityriasis amiantacea - Case reports 25506575 NIH
Nisy zazalahy 14 taona niditra niaraka tamin’ny kirany matevina mavo teo amin’ny hodiny, indrindra ny eo anoloana sy tampony. Mena sy mivaloarika ireo faritra voakasika; misy volo very fa tsy misy takaitra. Ny fitsapana ho an'ny holatra dia ratsy.
A 14-year-old male patient presented with focal masses of thick, adherent, plate like, yellow-brown scales, attached to the hair shafts, predominantly affecting the fronto-parietal area and vertex of the scalp. The underlying scalp had thick, erythematous plaques with fine, non greasy, silvery-white scaling with noncicatricial alopecia. Potassium hydroxide examination of scales and hair and culture for fungus was negative.
Pityriasis amiantacea: a study of seven cases 27828657 NIH
The disease may be secondary to any skin condition that primarily affects the scalp, including seborrheic dermatitis. Its pathogenesis remains uncertain. We aim to analyze the epidemiological and clinical profiles of patients with pityriasis amiantacea to better understand treatment responses. We identified seven cases of pityriasis amiantacea and a female predominance in a sample of 63 pediatric patients with seborrheic dermatitis followed for an average of 20.4 months. We reported a mean age of 5.9 years. Five patients were female, with a mean age of 9 years. All patients were successfully treated with topic ketoconazole.
Ny Pityriasis amiantacea dia miteraka kirany matevina mamirapiratra amin'ny hodi-doha. Ireo kirany dia mihodina ary mamehy ny volo. Ny toe-javatra dia mety ho eo an-toerana na mandrakotra ny hodi-doha manontolo. Mety hiseho ny alopecia vonjimaika na ny alopecia ateraky ny fanesorana miverimberina ny volo miraikitra amin'ny kirany. Izy io dia aretina tsy fahita firy.
