Description
Summary:A 49-year-old female from China was referred to our hospital after endocervical polypectomy. Twenty years before admission, after the birth of her first child, an intrauterine device (IUD) had been inserted due to the one-child policy in China. She had noticed abnormal vaginal bleeding with a foul smell 3 years before admission. Then the IUD was removed and a polyp was found at the IUD contact site. Two months before admission, endocervical polypectomy was performed. Lymphoma was suspected by histological examination and she was referred to our hospital. Further examination confirmed the diagnosis of primary uterine diffuse large B-cell lymphoma (DLBCL). Subsequently, a combination of three cycles of R-CHOP regimen and involved-field radiation therapy was performed, followed by maintenance therapy with five cycles of rituximab. She has remained in complete remission for over 1 year. This case suggests that chronic inflammation induced by prolonged IUD insertion may contribute to the development of primary uterine lymphoma. To the best of our knowledge, this is the first reported case of DLBCL associated with prolonged IUD insertion.
