A case of pleomorphic hyalinosis vasodilatation tumor of gastroomental soft tissue
Pleomorphic hyalinizing angiectatic tumor(PHAT)is a very rare low-grade neoplasm of un-certain 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 ana-lyze the relevant literature to improve the further understanding of the disease.
