From: Spindle cell squamous cell carcinoma exhibiting prominent neutrophil phagocytosis: a case report
Histopathological findings of the biopsy specimen. A The polypoid mass was composed of loose granulation tissue with an ulcerated surface. B Atypical spindle cells with pleomorphic nuclei were scattered together with inflammatory cells within the edematous and fibrin-rich stroma. C No obvious neoplastic changes were observed in the covering squamous epithelium. D A portion of the atypical spindle cells showing atypical mitotic figures. E–G Neutrophil phagocytosis was frequently observed; some neutrophils lost their nuclei and appeared to be degraded (arrows). A–G hematoxylin and eosin staining; scale bars: 500 μm (A), 100 μm (B, C), and 20 μm (D–G)
