Abstract

Basaloid squamous cell carcinoma of the esophagus is very rare. Further, polypoid type of esophageal cancer is also rare. We have recently treated a case of basaloid squamous cell carcinoma which presented as a 1.3-cm esophageal polyp. A 48-year-old woman was referred to our hospital because of a polypoid mass at 36 cm distance from the upper incisor on endoscopic examination, and the result of the biopsy was basaloid squamous cell carcinoma. The patient underwent Ivor Lewis operation with lymph node dissection. Two basaloid squamous cell carcinomas, of 1.3 and 0.4 cm, were diagnosed in the final pathologic examination. Regular periodic follow-up showed no evidence of recurrence or metastasis in the 5-month postoperative period.

The macroscopic view of the surgically resected specimen. a The macroscopic view of the surgically resected specimen shows a 1.3 × 1 cm polyp at 2 cm distance from the gastroesophageal junction. b Mapping of the surgically resected specimen reveals a 1.3 × 1 cm and a 0.4-cm basaloid squamous cell carcinoma (black color). Multiple separated dysplastic areas were noted (green color).

Microscopic examination of the resected specimen. a The tumor consists of basaloid cells showing oval to round nuclei with open pale chromatin features. Frequent mitotic figures are also noted (HE stain, ×200). b The tumor shows a solid growth pattern with a comedo-like necrosis structure (left lower portion) (HE stain, ×10).
