Benignus adenoma. Májdaganat
Egyforma, egyenl? Utóbbiban sürübb területek, vonalszer?
Benignus follikuláros leziokban is el? Esetenként nagy, orsó alakú Lavomax és prosztatitis is jelen lehetnek, melyek vagy reaktiv stroma sejtek, vagy cystikus elfajulás területét övez?
A pajzsmirigyrák megelőzésének lehetőségei A pajzsmirigy apró kis egységekből áll, amelyeket follikulusoknak neveznek.
Fokális Hürthle sejte elváltozás is jel lehet. Amennyiben mikrofollikulus kevés van és csak fokalis atypiát látunk, még sejtgazdag preparatum esetén helyesebb a léziot benignusnak nevezni.
Májdaganat
Ilyen esetekben a beteg követése természetesen elengedhetetlen. A microbiopsy from a nodular goitre.
A thick fragment in which round 3D follicles are separated by collagenous stroma. Orangiophilic colloid is visible inside some follicles whose contours are round.
Where thinner a monolayer arrangement can be identified.

Bland thyrocytes in a microfollicular arrangement. A monolayered sheet of bland thyrocytes with bland chromatin and moderate amount of pale, delicate cytoplasm.
In the upper corner a follicle lined by similar cells is observed. Bare nuclei and microfollicles. Few microfollicles lined by uniform cells with delicate cytoplasm, round nuclei with fine chromatin and surrounded by bare nuclei MGG. A very low power view of a cellular lesion.
A very lower power view of a MGG stained smear from a follicular lesion.
It is very cellular, colloid is not visible and the cells are arranged in sheets, follicles or lie singly. At this magnification no commitment can benignus adenoma made as whether it is benign, suspicious or malignant.
At high power the cells are uniform. A microfollicular pattern of regular, uniform thyroid cells exhibiting some "flaring" at their surface, usually seen in functioning cells; they are also monolayered and no reowding is observed. A trabecular arrangement. The same cells may exhibit a trabecular arrangement; in benignus adenoma case the minimal degree of anisonucleosis is well within normal limits.
Anisonucleosis variability in the volume but not the shape of nuclei is of very little significance in all endocrine glands and is certainly not a criteria benignus adenoma malignancy MGG.
Bland, less cohesive thyrocytes. Nuclear detail is better seen in Papanicolaou stain: chromatin is fine and small chromocentres can be seen. Nuclear membrane is regular and thin while cytoplasm is delicate and transparent.

A cellular aspirate at low benignus adenoma. A medium power view of a microfollicular adenoma MGG. At this magnification lack of background colloid, uniformity of cells and microfollicular pattern are obvious. In the absence of nuclear atypia, crowding or papillary architecture these lesions are classified differently either as follicular lesion, cytologically benign, Thy3 or follicular lesion - indeterminate.
In benignus adenoma cases the physician must know that criteria to predict a well differentiated follicular carcinoma are only histological following excision of the lesion to search for capsular or vascular benignus adenoma. However an benignus adenoma surgical approach will result in many benign lesions being excised.
The cells are uniform and arranged in follicles. The same lesion at higher power confirms lack of nuclear atypia and a dominant microfollicular pattern.

Bare nuclei are seen in the background, a feature which is reassuring as it is usually associated with benign lesions. A microfollicular pattern: A microfollicular pattern. A microfollicular pattern MGG ; cells appear uniform and no crowding is observed, however few discohesive cells maintain their cytoplasm.
Citologiailag benignus follikuláris leziók:
A stromal fragment with mesenchymal nuclei. At MGG stroma is pinkish and fibrillary with mesenchymal cells appearing as elongated and usually hyperchromatic nuclei; the thyroid cells maintain a follicular architecture and are not arranged perpendicularly to the stroma as expected in a papillary lesion.
A monolayered sheet of bland thyrocytes. A sheet of monoyared bland thyrocytes surrounded by smaller follicles and bare nuclei. A microfollicular arrangement.
Bland follicles and bare nuclei. Follikuláris adenoma Benignus daganat, szolid egyszeri göb formájában jelenik meg, amelynek átmér?
Májdaganat Májdaganat — a máj leggyakoribb daganata az áttét. A májat érintő egyéb elsősorban a gyomor — és bélrendszer daganatok áttétjei húszszor gyakoribbak, mint az benignus adenoma májból kiinduló daganatok. A máj betegségei lehetnek az egész májat érintő ún. A máj daganatai gócos betegségek, melyek közül jó- és rosszindulatú elváltozásokat különböztetnek meg. A jóindulatú daganatok nagyon gyakoriak: nőkben gyakrabban jelentkeznek, többségük kialakulása fogamzásgátlók szedésével hozható összefüggésbe.
Klasszifikáció prognosztikai jelent?
