Teratoma vs Seminoma
Ob leeg teratoma thiab seminoma yog cov kab mob qog nqaij hlav, uas qhia qee yam ntawm cov yam ntxwv zoo sib xws, tab sis lawv txawv ntau txoj hauv kev. Teratoma yog ib tug zoo-encapsulated qog muaj cov khoom tau los ntawm tag nrho peb txheej kab mob, tab sis seminoma tshwm sim los ntawm cov kab mob cell epithelium ntawm cov seminiferous tubules. Kab lus no taw qhia qhov sib txawv ntawm ob nqe lus no.
Teratoma
Raws li tau hais los saum no, nws yog cov qog zoo uas muaj cov khoom siv los ntawm tag nrho peb cov kab mob cell txheej. Nws yog cais raws li mature thiab tsis paub tab yam uas tom kawg yog malignant. Tag nrho cov teratomas nyob rau hauv cov neeg laus yog cov kab mob lom, sib piv rau cov menyuam yaus hnub nyoog qis dua 12 xyoo uas lawv coj zoo li benign neoplasm.
Vim nws raug suav hais tias yog qog nqaij hlav hauv lub cev, nws tshwm sim thaum yug los. Tab sis qee zaum cov qog tsis kuaj pom txog thaum muaj hnub nyoog laus. Alpha feto protein tuaj yeem nce siab ntau.
Microscopically, teratoma qhia kev sib txawv ntawm somatic thiab muaj cov ntsiab lus ntawm tag nrho peb txheej kab mob; endoderm, mesoderm thiab ectoderm. Nws yuav muaj lub hlwb, ua pa thiab plab hnyuv mucosa, pob txha mos, pob txha, tawv nqaij, hniav lossis plaub hau.
Nyob hauv fetus, lawv tsis txaus ntshai tab sis tsis tshua muaj peev xwm ua rau muaj kev cuam tshuam loj thiab vascular nyiag uas tuaj yeem ua rau lub plawv tsis ua haujlwm hauv fetus.
Kev tswj hwm suav nrog kev phais kom tiav ntawm cov qog. Rau malignant teratomas, chemotherapy yog muab tom qab kev phais.
Seminoma
Nws yog tus mob khees xaws tshaj plaws thiab kho tau zoo tshaj plaws hauv cov qog ntshav. Nws feem ntau tshwm sim los ntawm cov kab mob epithelium ntawm cov tubules seminiferous.50% ntawm cov kab mob qog nqaij hlav hauv cov qog nqaij hlav yog seminoma. Yog hais tias nws tshwm sim nyob rau hauv lub zes qe menyuam, nws yog hu ua dysgerminoma thaum, nyob rau hauv lub hauv paus paj hlwb, nws yog hu ua germinoma.
Clinically tus neeg mob nthuav tawm lub qe qe, qe qe atrophy, mob testicular thiab mob nraub qaum tom qab metastasis mus rau vertebra.
Kev tshawb nrhiav pom suav nrog qib siab ntawm alkaline phosphatase, nce tib neeg chorionic gonadotropin. Hauv classic seminoma, ntshav alpha feto protein tsis siab.
Macroscopically, nws zoo li fleshy thiab lobulated loj. Cov qog yog bulging los ntawm qhov chaw txiav thiab cov hemorrhagic tej zaum yuav pom.
Microscopically, classic seminoma yog tus cwj pwm los ntawm cov zes ntawm cov kab mob loj-ib puag ncig uas muaj cov cell nyias nyias, lub hauv paus nuclei, cov nucleoli tseem ceeb, thiab cov cytoplasm ntshiab uas muaj ntau glycogen, uas zoo li cov spermatocytes hauv seminiferous tubule.
Lwm yam muaj xws li cov spermatic seminoma uas ua los ntawm kev loj hlob ntawm cov qog hlwb, uas zoo li cov spermatocytes thib ob. Anaplastic seminoma yog ntau pleomorphic thiab muaj tus nqi siab dua ntawm cov duab mitotic.
Kev tswj hwm suav nrog inguinal orchidectomy hauv yuav luag txhua kis. Cov qog kuj qhia tau tias muaj kev cuam tshuam loj heev rau kev kho hluav taws xob thiab tshuaj khomob nrog kev muaj sia nyob zoo ntawm >90% thaum ntxov.
Qhov txawv ntawm Teratoma thiab Seminoma yog dab tsi?
• Teratoma yog ib lub qog zoo encapsulated muaj cov khoom los ntawm tag nrho peb cov kab mob cell txheej thaum seminoma yog muab los ntawm cov kab mob epithelium ntawm lub seminiferous tubules.
• Teratoma zoo encapsulated.
• Hauv teratomas, qhov sib txawv ntawm benign thiab malignant yog nyob rau hauv kev koom tes kom loj hlob ntawm cov ntaub so ntswg, qhov chaw, thiab hnub nyoog ntawm tus neeg mob thaum seminoma yog feem ntau kho tau thiab kho mob cancer nyob rau hauv thaum ntxov theem.
• Kev nce qib alpha feto protein ntau feem ntau cuam tshuam nrog teratoma.
• Kev tswj ntawm teratoma suav nrog kev phais tag nrho ntawm cov qog thaum nyob rau hauv seminoma inguinal orchidectomy yog xav tau nyob rau hauv yuav luag txhua kis.
