RESUMO
Uterine cervical squamous cell carcinoma (SCC) with reactive multinucleated giant cells (MGC) is extremely rare. Here we present the case of a 49-year-old woman treated with radical hysterectomy, bilateral adnexectomy and lymph node dissection. Histologically, the cervical tumor was diagnosed as nonkeratinizing SCC of pT1b1N0M0, with negative surgical margin. Many MGC including osteoclast-like giant cells with immunohistochemical expression of cluster of differentiation 204, a marker for the M2 macrophage, were present around the tumor nests. The patient received postoperative radiation therapy and achieved 22 months of disease-free survival after the surgery. M2 macrophages promote aggressiveness of the carcinoma and it is suggested that SCC of the cervix with reactive MGC might have poor prognosis; however, our case paradoxically showed a favorable course. From literature review of six cases, including our case, the effect of MGC-reaction may vary with respect to other factors, such as age, cancer stage or histological type.
