What is tumour of benign epithelial tissue?

Tit shape tumour (Papilloma) by enclothe epithelial happening, the natural disposition outside be being shown to the surface grows, form a lot of hands to show appearance or tit shape are protuberant, can present cauliflower shape or villiform outward appearance. The root ministry of tumor constant narrower Cheng Di and normal organization are linked together.

Tumour of benign epithelial tissue

Tumour of 1. tit shape (Papilloma) by enclothe epithelial happening, the natural disposition outside be being shown to the surface grows, form a lot of hands to show appearance or tit shape are protuberant, can present cauliflower shape or villiform outward appearance. The root ministry of tumor constant narrower Cheng Di and normal organization are linked together. Below lens, each tit by the branch state that has blood-vessel its axle center is made character between connective tissue, the hyperplasia that its surface enclothes is epithelial differ because of genetic place and different, can be scale shape epithelial (columnar and graph 7-9) , epithelial or divide with a hyphen at the end of a line is epithelial. Bine of outer ear path, block and bladder and colonic tit shape tumour happen more easily evil change and form tit shape cancer, notable.

2. adenoma (Adenoma) is by gland the benign tumor that epithelial happening, see the point such as gland of gland of Yu Jia shape, ovarian, mammary gland, saliva and bowel more. The adenoma of mucous membrane gland submits polypous form more (graph 7-10) , the adenoma inside gland organ submits nodal form more, and often have coating, with all round normal tissue dividing line is clear. The gland body of adenoma and body of its origin gland are not only on the structure very similar, and often have certain exudation function. Different the gland body volume that adenoma depends on only outside this, configuration is more irregular, arrange more concentrated also. Happen at having the adenoma of the organ of flocculus and tracheal structure, its flocculus structure often is short of be like or not apparent, also form without conduit, reason cannot its secretion eduction.

According to the compositive composition of adenoma or configuration characteristic, can divide its the adenoma that it is bursa, fiber adenoma, polymorphous sex adenoma and polypous shape adenoma to wait for a type again.

(1) bursa adenoma (Cystadenoma) : Because adenoma organizes deposit of medium gland body secretion,be, gland antrum expands gradually and mutual be in harmony synthesizes bursa, the bursa antrum that size differs is seen on naked eye, get a name consequently. Bursa adenoma often happens at ovarian, also see gland of Yu Jia shape and pancreas occasionally. Ovarian bursa adenoma basically has two kinds of kinds: One kind is gland epithelial to bursa tit shape is shown to grow inside antrum, secrete size, reason calls adenoma of shape of serous sex tit (Serouspapillarycystadenoma) ; Another kind is secreted mucous, often be much room sex, bursa wall is much smoother, rare tit shape is proliferous, call adenoma of mucous sex bursa (Mucinouscystadenoma) . Adenoma of bursa of shape of serous sex tit happens more easily evil change, cancer of gland of bursa of fluidity of translate into oar (Serouscystadenocarcinoma) .

(2) fiber adenoma (Fibroadenoma) : Except gland epithelial hyperplasia forms gland body outside, still accompany hyperplasia of many fiber connective tissue at the same time, make the substance of tumour jointly. This tumour is the benign tumor with female common mammary gland.

(Tumour of 3) polymorphous sexual gland (Pleomorphicadenoma) reachs a variety of composition such as cartilage appearance organization to mix composition by gland organization, mucous appearance. Often happen at saliva gland, particularly common at parotid gland, added in the past say to mix tumour. Think this tumour is by parotid gland intercalary is in charge of commonly at present epithelial with flesh a kind of tumor that epithelial happening. Because dispersive flesh is epithelial between can appear mucous appearance matrix, can change be born to be organized for cartilage appearance, form polymorphous sex characteristic thereby. This tumour grows slow, but excision hind has a relapse more easily.

(Adenoma of 4) polypous shape (Polypousadenoma) happens at mucous membrane, submit polypous form, the base of a fruit and mucous membrane are linked together, see more at rectum (graph 7-10) , among them the surface submits tit form or villiform person evil change rate is higher. This tumour also sees at the place such as colonic, stomach, polyp of sex of the colonic much adenoma that send a gender often has familial transmissibility, not only canceration rate is very high, easily inchoate happening canceration.
