Qhov Tseem Ceeb Qhov txawv - Thymoma vs Thymic Carcinoma
Lub caj pas thymus yog lub luag haujlwm rau kev tsim cov T lymphocytes thaum menyuam yaus. Neoplasms ntawm thymus caj pas tshwm sim los ntawm nws cov epithelial hlwb hu ua thymomas. Ntawm qhov tod tes, thymic carcinomas yog cov qog nqaij hlav malignant tshwm sim los ntawm cov hlwb epithelial ntawm lub caj pas thymus. Raws li txoj cai, thymic carcinomas yog qhov tseem ceeb ntawm cov kab mob malignant ntawm thymomas. Yog li, qhov sib txawv tseem ceeb ntawm thymoma thiab thymic carcinoma yog thymomas yog cov neoplasms ntawm thymus caj pas tshwm sim los ntawm nws cov epithelial hlwb thaum thymic carcinomas yog qhov tseem ceeb ntawm cov kab mob phem ntawm cov thymomas.
Thymoma yog dab tsi?
Neoplasms ntawm thymus caj pas tshwm sim los ntawm nws cov hlwb epithelial hu ua thymomas. Cov qog no cov yam ntxwv muaj benign tsis paub tab T lymphocytes. Muaj peb lub ntsiab histological ntau yam ntawm thymomas li,
- Cov qog uas muaj cytologically benign thiab tsis-invasive
- Cov qog uas yog cytologically benign tab sis ntxeem tau lossis metastatic
- Cov qog uas yog cytologically malignant (thymic carcinoma)
Qhov tshwm sim ntawm thymomas yog siab ntawm cov neeg laus uas muaj hnub nyoog 40 xyoo. Lawv tsis tshua pom muaj menyuam yaus. Feem ntau ntawm thymomas tshwm sim nyob rau hauv lub anterior mediastinum. Lub caj dab, thyroid, thiab pulmonary hilus yog lwm qhov chaw uas tuaj yeem tau txais thymomas.

Morphology
Noninvasive thymomas feem ntau yog ua los ntawm kev sib xyaw ntawm medullary thiab cortical epithelial hlwb. Muaj ib qho tsis tseem ceeb thymocyte infiltration. Invasive thymomas feem ntau muaj cov hlwb cortical epithelial, thiab lawv nkag mus rau hauv cov qauv uas nyob ib sab los ntawm cov tshuaj ntsiav ntawm lub caj pas.
Tshuaj Kho Mob
Cov tsos mob feem ntau yog vim qhov cuam tshuam ntawm cov qauv uas nyob ib sab los ntawm qhov loj. Dysphagia, hnoos, mob hauv siab thiab hloov hauv lub suab yog qhov kev tsis txaus siab tshaj plaws. Muaj kev sib raug zoo ntawm myasthenia gravis thiab qhov tshwm sim ntawm thymomas. Muaj kev koom tes tseem ceeb nrog lwm cov kab mob autoimmune xws li Graves disease, Cushing syndrome, pernicious anemia, dermatomyositis, thiab polymyositis.
Thymomas raug kho los ntawm kev phais ntawm lub caj pas nrog cov kab mob neoplastic. Cov txheej txheem no hu ua thymectomy.
Tus kab mob Thymic yog dab tsi?
Thymic carcinomas yog cov qog nqaij hlav malignant tshwm sim los ntawm cov hlwb epithelial ntawm thymus caj pas. Cov no yog cev nqaij daim tawv nrog cov ciam teb tsis tu ncua, thiab lawv feem ntau metastasize rau qhov chaw nyob deb xws li lub ntsws. Squamous carcinomas thiab lymphoepithelioma yog hom cytological tshaj plaws ntawm thymic carcinomas. Cov kab mob EBV tau ntseeg tias ua lub luag haujlwm hauv kev ua haujlwm ntawm cov kab mob malignancies vim muaj EBV genome hauv cov hlwb malignant.

Ntxiv rau cov tsos mob ntawm tus kab mob thymoma, thymic carcinomas tuaj yeem muaj lwm cov tsos mob xws li poob phaus, tsis qab los noj mov, malaise thiab mob pob txha.
Kev tshawb nrhiav
Thymic carcinomas feem ntau yog kuaj pom los ntawm kev kuaj biopsies
Kev kho mob
Thymectomy thiab radiotherapy yog cov kev kho mob uas siv los tswj cov thymic carcinomas.
