Poorly Differentiated Cervical Squamous Cell Carcinoma Resembling Giant Cell Carcinoma of the Lung: Extreme Morphology of This Tumor and Its Clinical Course

Abstract

Giant cell tumor is a highly aggressive tumor characterized by a marked proliferation of pleomorphic, bizarre giant cells usually observed in the lungs. The importance of histopathological imaging and the clinical course of this tumor are unknown. The objective of our report was to investigate whether these components affect treatment outcomes and prognosis compared to conventional cancers. A 40-year-old woman with cervical cancer showed leukocytosis and elevated granulocyte colony simulating factor (G-CSF). The patient underwent a radical abdominal hysterectomy. Pathology revealed a poorly differentiated squamous cell carcinoma of the cervix, similar to giant cell carcinoma. The patient recovered from the disease and is alive 37 months after concurrent chemoradiotherapy (CCRT). Leukocytosis and G-CSF were normalized after treatment. This was our second case of giant cell carcinoma of the cervix. Cumulative data on giant cell carcinoma are limited, thus we considered the prognostic significance of the presence of giant cell carcinoma in uterine carcinoma.
