Agradecemos especialmente el comentario de Prof Dra Isabella Doche. Dermat\u00f3loga- Tric\u00f3loga, experta en tricoscopia. <\/strong><\/p>\n

CASE A<\/strong>
\nThis is a case of chronic lichen simplex. In trichoscopy the most prominent finding is the proximal trichorrhexis nodosa (PTN) due to frequent scratching. The essential abnormality of TN is the formation of nodes along the hair shafts through which breakage occurs. In PTN, broken hairs have similar length and show a whitish tip due to the cortical damage which can be better appreciated in trichoscopy with higher magnification. Dischromia and scales can also be found as a result of local inflammation and trauma. There main differential is trichotillomania. However, in this condition the nodes are absent and the hairs are broken at different lengths. In this case antipruritic medications and topical steroids may be beneficial. <\/p>\n

Traducci\u00f3n:<\/i> Este es un caso de liquen simple cr\u00f3nico. En la tricoscopia, el hallazgo m\u00e1s prominente es la trichorrhexis nodosa proximal (PTN) debido al rascado frecuente. La anormalidad esencial de la TN es la formaci\u00f3n de n\u00f3dulos a lo largo del tallo del cabello a trav\u00e9s del cual se produce la rotura. En la PTN, los pelos rotos tienen una longitud similar y presentan una punta blanquecina debido al da\u00f1o cortical que puede apreciarse mejor en la tricoscopia con mayor aumento. La discrom\u00eda y las escamas tambi\u00e9n se pueden encontrar como resultado de la inflamaci\u00f3n y el trauma local. Su principal diferencial es la tricotiloman\u00eda. Sin embargo, en esta condici\u00f3n los ganglios est\u00e1n ausentes y los pelos est\u00e1n rotos a diferentes longitudes. En este caso, los medicamentos antipruriginosos y los esteroides t\u00f3picos pueden ser beneficiosos.<\/p>\n

CASE B <\/strong>
\nPressure-induced alopecia is a patchy alopecia that occurs after local traumas or a prolonged immobile state of the scalp. Although most cases are nonscarring and complete hair regrowth occurs, some may lead to scarring lesions. Hair loss is due to hypoxia changes in certain areas of the scalp, caused by pressure. The main differential is alopecia areata and the clinical history is fundamental to make a correct diagnosis. In this case, topical minoxidil may help the hair regrowth. <\/p>\n

Traducci\u00f3n:<\/i> La alopecia inducida por presi\u00f3n es una alopecia irregular que ocurre despu\u00e9s de traumas locales o un estado inm\u00f3vil prolongado del cuero cabelludo. Aunque la mayor\u00eda de los casos no dejan cicatrices y se produce un recrecimiento completo del vello, algunos pueden conducir a lesiones con cicatrices. La p\u00e9rdida de cabello se debe a cambios de hipoxia en ciertas \u00e1reas del cuero cabelludo, causados por la presi\u00f3n. El principal diferencial es la alopecia areata y la historia cl\u00ednica es fundamental para hacer un diagn\u00f3stico correcto. En este caso, el minoxidil t\u00f3pico puede ayudar a que el vello vuelva a crecer.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
