A CASE OF ESOPHAGEAL VERRUCOUS CARCINOMA HISTOPATHOLOGICALLY DIAGNOSED AFTER ESD

Abstract

In a 75-year-old male, EGD revealed a 2-cm, white, flattened, elevated lesion without iodine staining in the mid-thoracic esophagus. Although histopathological examination of the biopsy tissue revealed papilloma, superficial esophageal cancer could not be completely ruled out. ESD was performed as a diagnostic treatment. Pathological examination of the resected specimen revealed squamous cell carcinoma with a depth of pT1a-EP, which was consistent with verrucous carcinoma. Four years after the ESD, the patient is still being followed up without recurrence.
