胃网膜软组织多形性透明变性血管扩张性肿瘤1例

A case of pleomorphic hyalinosis vasodilatation tumor of gastroomental soft tissue

多形性透明变性血管扩张性肿瘤(PHAT)是一种非常罕见的好发于结缔组织或其他软组织的行为不确定的低级别肉瘤。目前对PHAT报道甚少,且由于其罕见性,谱系尚未完全阐明。该研究旨在通过对1例发生在胃网膜软组织的PHAT临床资料、病理学特征、镜下形态及免疫组织化学染色结果进行观察和鉴别诊断,并结合相关文献进行回顾性分析,以提高对该病的进一步认识。

Pleomorphic hyalinizing angiectatic tumor(PHAT)is a very rare low-grade neoplasm of uncertain behavior which tends to occur in connective or other soft tissue.At present there are very few reports on it,and due to the rarity,its lineage has not been fully elucidated.The purpose of this study was to observe the clinical data,pathological general,microscopic morphology and immunohistochemical staining results of PHAT in one case of gastroomental soft tissue and to make differential diagnosis,and to retrospectively analyze the relevant literature to improve the further understanding of the disease.
