瘤形

Methods We reported a case of PXA located in the cerebellum of a young adult in view of its extremely unusual location. Morphologic observation, immunohistochemical staining using DAKO EnVision system , histochemical stains including hematoxylin eosin and Gordon Sweet's reticulin methods were used.

采用免疫组织化学DAKOEnVison法、组织化学网质纤维染色和HE染色及形态学观察的方法，报道 1例极罕见于年轻人小脑的多形性黄色星形细胞瘤，探讨其临床病理特点。

Histologically, there were two patterns: purely epithelioid types (5 cases), among there were 2 cases consist of anglion cell or rhabdoid phenothype, mixed types with areas of spindle cells (4 cases).

深在型8例，浅在型1例，组织学，纯上皮样型5例，其中2例见节细胞样或横纹肌样瘤样区域，4例混合型伴有梭形细胞区。

Nutlets erect, semiovoid, adaxial aperture 2-layered, longitudinal, ringlike, abaxially convex, tuberculate, inside layer membranous; attachment scar basal, orbicular-triangular.

直立的小坚果，半卵形，正面的孔2层，长度，环形，背面凸面，具瘤，在膜层里面；附件痕基部，圆形三角形。

There were 2 components: uniform oval or spindled cells in diffuse sheets, and clusters or cords of epithelial cells occasionally forming glandular structures with small lumens.

瘤组织有两种成分：卵圆形或梭形细胞弥漫排列；上皮细胞排列成簇或成索，偶见小腺管形成。

Spindled zones blended imperceptibly into areas showing epithelial differentiation, in the form of glomeruloid glandular structures, sertoli-like tubules, and small glands, lined by cuboidal to columnar cells.

梭形细胞区与上皮样分化区互相掺杂，立方状或柱状瘤细胞排列成肾小球样腺管结构、支持细胞样小管结构和小腺管结构。

The tumors ranged from 5.5 to 20 cm and had a characteristic histologic appearance with irregular, sharply circumscribed nests and islands of bland-appearing spindled to focally epithelioid cells, surrounded by a cellular desmoplastic stroma.

这9例肿瘤大小为5.5至20cm，瘤组织特征性地表现为：温和的梭形细胞至灶性上皮样细胞排列成巢或成岛，这些细胞巢团界限相当清楚但不规则，周围间质细胞丰富、促纤维组织增生性。

Leaf sheaths glabrous or sparsely to densely pilose with tubercle-based hairs; leaf blades broadly linear, 5–20 × 0.5–1.5 cm, pubescent, rarely glabrescent, base rounded to subcordate, apex acute; ligule 1–2 mm. Racemes (2–)3–6 or more, mostly terminal, subdigitate, 2–9 cm; rachis internodes and pedicels broadly linear, triquetrous, ciliate on outer angle, shortly ciliate on inner angles.

叶鞘无毛或疏生在密被柔毛具基于小瘤毛；叶片宽线形， 5-20 * 0.5-1.5 厘米，短柔毛，很少脱落无毛，基部圆形到近心形，先端锐尖；叶舌外消旋体1-2毫米(2-)3-6或更多，主要末端，2-9厘米，subdigitate；轴节间和花梗宽线形，在外部角上三棱，纤毛，在内部角上不久纤毛。

Plants 20--50 cm tall; inflorescences concentrated into capitula, pedicels 0.5--2.5 mm; bracts and calyx lobes undulate at margin, not ciliate; seeds truncately tuberculate

植株20 --50厘米高；花序进头状，花梗0.5被集中--2.5毫米；苞片和萼裂片边缘波状，不具缘毛；种子截形具瘤 2 G。 cephalotes 膜苞石头花

The tumor cells are large in size, very pleomorphic, and have abundant, vacuolated to dense cytoplasm, and hyperpchromatic nuclei with irregular contours and prominent nucleoli.

瘤细胞个大，多形性明显，浆丰，胞浆从空泡状到致密，核深染，外形不规则，核仁明显。

Plant bearing squash having globose to ovoid fruit with variously striped gray and green and white warty rinds.

结有条纹的球形或卵形果实，有白色绿色或灰色的瘤。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
