Benignus adenoma
Benignus – Wikipédia
Egyforma, egyenl? Utóbbiban sürübb területek, vonalszer? Benignus adenoma follikuláros leziokban is el?
Esetenként nagy, orsó alakú sejtek is jelen lehetnek, melyek vagy reaktiv stroma sejtek, vagy cystikus elfajulás területét övez? 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. 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 benignus adenoma 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.
Citologiailag benignus follikuláris leziók:
At this magnification no commitment can be 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 this 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 for malignancy MGG.
Bland, less cohesive thyrocytes.
Recurrent Pituitary Adenomas - What are the Options?
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 power. A Krónikus pyelonephritis és prosztatitis kezelése 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 all 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 invasion. However an aggressive 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 benignus adenoma 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.

A stromal fragment with mesenchymal nuclei. At MGG stroma is pinkish and fibrillary with mesenchymal cells appearing as elongated benignus adenoma usually hyperchromatic nuclei; the thyroid cells maintain a follicular architecture and are not arranged perpendicularly to the stroma as expected in a papillary lesion.
Májdaganat Májdaganat — a máj leggyakoribb daganata az áttét. A májat érintő egyéb elsősorban a gyomor — és bélrendszer daganatok áttétjei húszszor gyakoribbak, mint az elsődlegesen májból kiinduló daganatok.
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?
A pajzsmirigyrák megelőzésének lehetőségei A pajzsmirigy apró kis egységekből áll, amelyeket follikulusoknak neveznek. A follikulusok hámsejtjei veszik körül azt a piciny területet, ahol a megtermelt hormonok tárolódnak.
