Purpose To investigate the clinical and pathological features of inflammatory fibroid polyps ( IFPs) and to discuss its diag-nosis, differential diagnosis and treatment. Methods Clinicopathological data of 14 cases of IFPs were collected and analyzed retro-spectively. Results Most of the 14 cases were found to have submucosal polyps of the digestive tract protruding growing into the cavi-ty. Perivascular onion skinning which formed by spindle fibrocytes around vascular proliferation and eosinophilic inflammatory infiltrates were present as the characteristic feature of lesions. ABC results demonstrated that the lesions showed fibroblastic, myofibroblastic and dendritic cell signs. Conclusions IFPs are rare, benign tumors that can arise throughout the digestive tract, with unique histological changes in pathology. Surgical excision or endoscopic removal is the main treatment.

Objective To investigate the expression of KLF4 in cervical carcinoma and its significance. Methods Immunohistochemistry and tissue microarray were used to examine the expression of KLF4 in 39 cases of carcinoma, 30 cases of normal cervical epithelial tissues and 28 cases of cervical cancer in situ. Results Moderate to strong nuclear staining for KLF4 was found in normal tissues and cervical cancer in situ. Interestingly, KLF4 expression was lost in 16 (P<0.05) of 39 carcinoma cases. However, KLF4 expression was not associated with clinicopathologic parameters, including tumor stage and differentiation. Conclusion Our observations indicate that KLF4 may function as a tumor suppressor in the pathogenesis of cervical cancer.
