Micro-pituitary chromophobe adenoma of two cases
28 deaths. Autopsy, the light microscope, found pituitary adenoma, but not before his death in patients with clinical manifestations of pituitary adenoma pituitary gland biopsy,MBTシューズ 販売店, giant check: oval, diameter lcm, both surface and cut surface showed no abnormal endoscopic, anterior pituitary Central see a cells, and round, incomplete fibrous capsule and surrounding tissue is separated from the smaller diameter of lmm cells, form similar, less cytoplasm, slightly addicted to alkaline, the cell state is unclear, from the more dense arrangement of film, part a tendency to form glands, edge round or oval, fine chromatin, nuclear membrane clearly and meager, small nucleolus, no mitotic figures; interstitial less abundant sinus-like capillaries. PAS staining of a orange G, light gray-blue stained these cells for the pathological diagnosis; pituitary chromophobe down microadenomas 2t male, 34 years old. Suffering from malignant histiocytosis with pulmonary edema, brain herniation and in August 30,vibram five fingers singapore, 1984 death. Autopsy, the microscope found that urea pituitary tumor,mbt zapatos, but no pituitary adenoma patients with the symptoms before death. Preserved the basic with the cases of pituitary pathology l, differences are (1) than patients with adenoma size l large, its diameter is 2mm; (2) in the mixed chromophobe cell is still a small amount of large, clear state of eosinophil cells ; (3) PAS staining of a orange G, was pulled blue chromophobe, eosinophil-positive (orange). Pathological diagnosis was chromophobe t pituitary microadenomas. Zhuang Wenhua Li feather fan. One hundred and eleven,,, t this discussion were two down with pituitary chromophobe adenoma of the microscopic features: tumor cells form small polygonal and more consistent. Moderate amount of cytoplasm,tory burch outlet, lightly stained, state is unclear, the nuclear medium round or oval, thin and uniform chromatin, thin nuclear membrane, nucleolus small or unclear,tory burch shoes, edge split rare. Histologically, the tumors generally can be divided into three subtypes, namely; diffuse, sinus gap type and papillary type, which diffuse the most common to large areas of tumor cells characterized by closely arranged, for example l, Example 2 are meet this type, and tumor cells have the tendency to form glandular. Chromophobe pituitary adenoma on the cell eat to the sex is still not conclusive, that this case is purely a chromophobe adenoma of the pituitary adenoma without clinical symptoms, but also gradually being valued by the people. Schochet 1558 cases in adults such as autopsy, found pituitary adenoma were 193 patients there. Most of these tumors are smaller, which diameter <10mm were two cases of paper called microadenomas, in 2ram tumor diameter less than a typical micro-adenoma. Clinical experience shows that: the smaller the effect of surgery of pituitary adenoma size as possible. In recent years, with early diagnosis of pituitary microadenomas the growing importance of pituitary adenoma diagnosis of small or micro-level has been the constant increase. Such as through the cavernous sinus contrast between the observed small pituitary adenoma characteristics of x-ray. Contribute to its diagnosis, especially for the pituitary gland or to the back side next to the growth of micro-adenomas more accurate. In addition, by observing the pituitary CT images, it also shows the characteristics of a reliable diagnostic indication of microadenomas. But the tiny micro-morphological changes of pituitary adenoma have little effect, the diagnosis more difficult. |
