Abstract

Two cases of large intestinal submucosal lipomas with atypical features are described. These atypical features consist of cellular fibrosis, atypical hyperchromatic nuclei, and increased mitotic activity, with the occasional presence of atypical mitoses. They were associated with ulceration and appeared to be reactive in nature. The major importance lies in distinguishing these lesions from truly sarcomatous tumors.

摘要

本文描述了两例具有非典型特征的大肠黏膜下脂肪瘤。这些非典型特征包括细胞纤维化、非典型深染核以及有丝分裂活性增加，偶尔还可见非典型有丝分裂。它们与溃疡相关，似乎本质上是反应性的。主要重点在于将这些病变与真正的肉瘤性肿瘤区分开来。
