The pathologic characteristics of the gum quality cell lump

From out of the nerve Pei layer derivation since then of the gum quality cell have the star polygon gum the quality cell, little Tu gum quality cell and room to take care of film cell etc., they can take place tumor, and produce the gum quality of various each kind type from here lump.Currently, the clinical pathologic classification of gum quality lump hasn't completely unified and a little bit extensively apply of have 2 kinds:①The classification method that Bailey and Cushing(1926) put forward.This kind of classification the method organize according to the different nerve embryo, certainly homologous tumor type name, predicts that the patient has after preparing to the clinical doctor certain help, but it neglected an of tumor to change characteristic, also not the occurrence and development of the treating of ability dynamic state gum quality lump.②The classification method that Svien and Kernohan(1949) put forward.This classification method is divided into 5 sets: all gum quality lumps, namely the star polygon cell lump, room tube film lump, little Tu cell lump, the nerve-star polygon cell lump and become nerve tube cell lump.In addition to becoming the nerve tube cell lump, other personal set according to it bad change the degree is again divided into this tumor that urges cell formation the Ⅰ and Ⅱ , Ⅲ and Ⅳ is four classes.This advantage that urges to categorize a method is more simple, the weakness is some tumors can not also make sure that they are basically to come from that each cell and have some another tumor to only have a malignant form now, the ratings then has no actual meaning.These two kinds of classification methods, all extensively apply in the world currently in clinical.
In 1977, gear hygiene organization the assigning name to of central nervous system system tumor put forward to propose with classification and make the nerve skin being divided into 6 types organization tumor, namely the ① star polygon cell lump;②Little Tu gum quality cell lump;③The room takes care of film and grain cluster tumor;④Loose fruit body cell lump;⑤Nerve dollar tumor;⑥The low mark turns and embryo tumor, include into the gum quality cell lump and the nerve take care of cell lump etc..
There are two high peaks on the outbreak age of gum quality lump, on being 7~13 years old, with become the nerve absolute being tube cell lump, the cerebellum star polygon cell lump, see the nerve gum quality lump and loose fruit originally lump for much see;Another is 25~45 years old, with the brain star polygon cell lump, multiformity become the gum quality cell lump and little Tu anti- the United States to aid the dynasty cell lump for much see.The gum quality lump of different type has respectively of good hair part.The adult star polygon cell lump is seen to brain hemisphere more, while the child is seen to the cerebellum hemisphere cerebellum Yin more a department is become nerve tube the cell lump deliver part so much, little Tu gum quality cell lump much hair at the brain hemisphere deep department inside the white quality, the room takes care of film lump and grain cluster nipple-like in shape lump much occurrence at brain the indoor etc..
