Inflammatory Pseudotumor of Lymph Node - A Case Report

Abstract

Inflammatory pseudotumor of lymph node is a rare disease with a chronic course. It is usually spontaneously recovered. Perinodal soft tissues are involved, thus clinically malignant condition is suspected. We report a case of inflammatory pseudotumor of cervical lymph node occurred in a 37-years old woman. We performed light microscopy, and immunohistochemical staining. Histologically, the component cells are mainly spindle shaped and form bundles and whorls, often giving rise to a storiform pattern. Variable inflammatory cells and Reed-Sternberg like cells are noted. The spindle cells show strong reactivity for vimentin and CD68. They do not express CD3, CD20, and CD21. Inflammatory pseudotumor of lymph node is a rare spindle cell lesion and sometimes is confused as other malignant conditions.
