Lichen planus
☆ En els resultats de la Stiftung Warentest d'Alemanya de 2022, la satisfacció dels consumidors amb ModelDerm va ser només lleugerament inferior a la de les consultes de telemedicina de pagament.
Les lesions àmplies a les dues canyelles són atípiques. En aquest cas, solen ser més sospitades altres malalties al·lèrgiques cròniques (lichen simplex chronicus).

Lichen planus (LP) és una malaltia inflamatòria de llarga durada que afecta principalment els adults en els seus anys mitjans. Pot aparèixer a la pell o a les mucoses com la boca, la vagina, l'esòfag, la caixa de veu i el revestiment dels ulls. LP es presenta en diferents formes depenent de com es veuen les erupcions i on apareixen. Els estudis suggereixen que certs tipus de LP, com els que afecten l'esòfag o els ulls, poden no ser diagnosticats prou. Algunes formes de LP, com els tipus hipertròfics i erosius a la boca, poden ser especialment pesades i durar molt de temps. Altres factors com els medicaments o el contacte amb determinades substàncies poden desencadenar erupcions cutànies d'aspecte similar.
Lichen planus (LP) is a chronic inflammatory disorder that most often affects middle-aged adults. LP can involve the skin or mucous membranes including the oral, vulvovaginal, esophageal, laryngeal, and conjunctival mucosa. It has different variants based on the morphology of the lesions and the site of involvement. The literature suggests that certain presentations of the disease such as esophageal or ophthalmological involvement are underdiagnosed. The burden of the disease is higher in some variants including hypertrophic LP and erosive oral LP, which may have a more chronic pattern. LP can significantly affect the quality of life of patients as well. Drugs or contact allergens can cause lichenoid reactions as the main differential diagnosis of LP.

Lichen planus és una afecció de la pell marcada per cops i pegats de la part superior plana i porpra que poden causar picor intensa. Aquestes lesions cutànies poden ser angoixants, sobretot quan afecten greument la boca o els genitals. En casos greus, oral lichen planus fins i tot pot augmentar el risc de desenvolupar un tipus de càncer de pell. També pot afectar el cuir cabellut i les ungles. Tot i que es desconeix la causa de la majoria dels casos, alguns poden ser provocats per determinats medicaments o infecció per hepatitis C. El tractament normalment inclou cremes fortes per als casos localitzats i esteroides orals per als més estesos.
Lichen planus is a skin condition marked by purplish, flat-topped bumps and patches that can cause intense itching. These skin lesions can be distressing, especially when they affect the mouth or genitals severely. In severe cases, oral lichen planus may even increase the risk of developing a type of skin cancer. It can also affect the scalp and nails. While the cause of most cases is unknown, some may be triggered by certain medications or hepatitis C infection. Treatment typically involves strong creams for localized cases and oral steroids for more widespread ones.

Lichen planus és una afecció on el sistema immunitari provoca inflamació, donant lloc a marques distintives a la pell i les mucoses. Afecta al voltant del 5% dels adults, més sovint dones, i sol començar cap a l'edat mitjana. Fins a un 77% dels casos s'observa afectació oral, afectant majoritàriament la galta interna. Tot i que algunes persones poden no sentir cap símptoma, altres poden experimentar dolor i tenir problemes amb determinats aliments (per exemple, àcids, picants) o pasta de dents.
Lichen planus is an immune-mediated inflammatory condition leading to characteristic lesions on skin and mucous membranes. It presents in up to 5% of the general adult population with a female predilection (2:1); the onset is most commonly in middle age. Up to 77% of patients with lichen planus have oral disease, with buccal mucosa the most common subsite. The oral lesions may be asymptomatic, although a subset of patients have pain and difficulty tolerating certain foods (e.g., acidic, spicy) and toothpaste.

Per confirmar el diagnòstic de liquen pla cutani, es pot fer una biòpsia de pell. La immunofluorescència directa (DIF) pot ser útil en pacients amb lesions bulloses per diferenciar la malaltia d'una malaltia vesiculobulosa autoimmune.
