Lichen planus papules khaus yuav luag tas li.

Tom qab ntawd cov papules liab doog thiab muab txoj kev mus rau ib tug residual pigmentation nws cov xim txawv ntawm lub teeb xim av mus rau xiav, txawm dub. Peb tab tom tham txog pigmentogenic lichen planus

2 / Mucous lichen planus

Nws yog kwv yees hais txog ib nrab ntawm cov neeg mob uas cutaneous lichen planus muaj mucosal kev koom tes cuam ​​tshuam. Lichen planus tseem tuaj yeem cuam tshuam tsuas yog cov mucous daim nyias nyias uas tsis muaj daim tawv nqaij koom nrog hauv ¼ ntawm cov neeg mob.

2.A/ Lichen txoj kev npaj buccal

Qhov ncauj lichen planus suav nrog cov ntaub ntawv kho mob hauv qab no: reticulate, erosive, thiab atrophic. Qhov chaw nyiam yog cov mucosa lossis tus nplaig.

2.Aa / Reticulated buccal lichen planus

Reticulate lesions feem ntau yog tsis muaj tsos mob (tsis kub, khaus…) thiab ob sab ntawm ob sab sab hauv ntawm lub puab tsaig. Lawv tsim ib lub network dawb hauv " nplooj fern ".

2.Ab/ Lichen plan buccal érosif

Erosive lichen planus yog tus cwj pwm los ntawm eroded thiab mob mucous cheeb tsam nrog ntse ciam teb, npog nrog pseudomembranes, nyob rau hauv keeb kwm liab, seb puas los yog tsis txuam nrog reticulated lichenian network. Nws zaum nyiam nyob rau ntawm sab hauv ntawm lub puab tsaig, tus nplaig thiab cov pos hniav.

2.Ac/Lichen npaj atrophique

Atrophic daim ntawv (cov mucous daim nyias nyias nyias ntawm thaj chaw ntawm lichen) tau yooj yim pom ntawm cov pos hniav uas ua rau khaus thaum txhuam hniav thiab sab nraum qab ntawm tus nplaig, ua rau depapillation, ua rau tus nplaig rhiab heev rau cov khoom noj ntsim..

2.B / Qhov chaw mos lichen planus

Lichen planus kev koom tes ntawm genitalia yog heev rarer tshaj qhov ncauj kev koom tes.

• erosive vulvitis, thiab tej zaum ib tug reticulate network nyob ib ncig ntawm qhov txhab;

• erosive vaginitis;

• erosive sheet gingivitis, txawm tias tsis cuam tshuam nrog lwm cov kab mob ntawm qhov ncauj lichen.

3. Kev koom tes nrog Phanereal (plaub hau, ntsia hlau, plaub hau)

3.A / Cov plaub hau lichen planus: follicular lichen planus

Cov plaub hau puas tuaj yeem tshwm sim thaum muaj kev sib kis ntawm cutaneous lichen planus, nyob rau hauv daim ntawv ntawm me me acuminate crusty cov ntsiab lus nyob nruab nrab ntawm cov plaub hau, peb hais txog spinulosic lichen.

3.B / Lichen planus ntawm cov plaub hau: lichen planus pilaris

Nyob rau saum tawv taub hau, lichen planus yog characterized los ntawm thaj chaw ntawm alopecia (chaw tsis muaj plaub hau) caws pliav (cov tawv taub hau yog dawb thiab atrophic).

Lub syndrome Lassueur-Graham-Little koom nrog kev tawm tsam ntawm tawv taub hau, spinulosic lichen, nrog rau lub caij nplooj zeeg ntawm axillary thiab pubic plaub hau.

3. C / Lichen planus ntawm cov ntsia hlau: ntsia thawv lichen planus

Cov ntsia hlau feem ntau cuam tshuam thaum mob hnyav thiab diffuse planar lichen. Feem ntau muaj ib thinning ntawm tus ntsia thawv ntsiav tshuaj nyiam ua rau cov ntiv taw loj. Nail lichen planus tuaj yeem nce mus kev puas tsuaj thiab irreversible pterygium-zoo li qhov txhab (tus ntsia thawv raug rhuav tshem thiab hloov ntawm daim tawv nqaij).
