Double esophageal duplication cysts, with ectopic gastric mucosa: a case report.

Zhang Z, Jin F, Wu H, Tan S, Tian Z, Cui Y - J Cardiothorac Surg (2013)

Bottom Line: The small (1-cm) esophageal cyst was left untreated based on a "wait-and-see" policy.This finding was consistent with a diagnosis of EDC, with ectopic gastric mucosa.The respiratory tract symptoms resolved immediately after the operation.

ABSTRACT
Esophageal duplication cyst (EDC) is a congenital malformation of the posterior primitive foregut, which mainly occurs in the thoracic esophagus. Here, we describe a 3-year-old Han Chinese boy afflicted with intermittent fever of acute onset and dry cough. Thoracic computed tomography revealed an 10 cm × 5.4 cm × 5.8 cm oval-shaped, cyst-like tumor located in the extrapleural space, extending along the right paravertebral gutter and compressing the trachea forward. An additional small-sized, oval-shaped cyst was identified in the posterior mediastinum, between the esophagus and the spinal column, at the T1 level. During open thoracotomy, under general anesthesia, an opaque, thick-walled, esophageal cyst was revealed not to be in communication with the esophageal lumen or the trachea. This cyst was subsequently resected in an en bloc manner. The small (1-cm) esophageal cyst was left untreated based on a "wait-and-see" policy. Histological analysis showed that the resected cyst was walled by hyperplastic, fibrous tissues and locally lined with gastric mucosa inherent glands. This finding was consistent with a diagnosis of EDC, with ectopic gastric mucosa. The respiratory tract symptoms resolved immediately after the operation. Computed tomography obtained at the 6-month follow-up showed that no disease, residual or recurrence, was present after the resection of the large-sized cyst, and the small-sized cyst remained unchanged in size.

Figure 4: Pathology of the resected large-sized esophageal duplication cyst. Histology revealed esophageal duplication cyst with ectopic gastric mucosa (hematoxylin-eosin, 400×).

Mentions: Gross pathology of the resected specimen showed a grayish cystic mass, with a 0.3-cm-thick wall, lined with brownish, rough epithelial-like tissue. Histological analysis of the resected esophageal cyst revealed that the cyst wall was composed of hyperplastic fibers and lined with stratified squamous epithelium, containing gastric mucosal simple columnar epithelium (Figure 4). The disease was then histologically diagnosed as EDC with ectopic gastric mucosa.
