A type of neoplasia deadlier than gastric adenocarcinoma? Report of a case of primary gastric squamous cell carcinoma

Abstract

BACKGROUND: Primary gastric squamous cell carcinoma is an extremely rare malignancy with few case reports reported so far in the current medical literature. Its incidence varies between 0.04 and 0.07% of all gastric malignancies with a male predominance in the sixth decade of life. It has been found that this type of malignancy has a more aggressive behavior and associated poorer prognosis, when compared to gastric adenocarcinoma. Thus, the most appropriate management of this kind of neoplasia is still debatable due to the small number of reported cases. CASE PRESENTATION: We report the case of a 66-year-old man who underwent total gastrectomy with D2 lymphadenectomy for an ulcerative lesion in the fundus of the stomach that turned out to be primary gastric squamous cell carcinoma. CONCLUSIONS: Upon confirmation of this specific malignancy, the affected patients should be enrolled in strict follow-up protocols after curative surgery, since the risk for metastasis is high. Physicians should maintain high clinical suspicion in order to diagnose these tumors at an early stage, along with the need to rule out any other possible primary sites of squamous malignancy.
