Ectopic sebaceous glands are rare esophageal findings. This report details two new cases diagnosed through endoscopic biopsy, highlighting this uncommon esophageal anomaly.
Area of Science:
- Gastroenterology
- Histopathology
- Ectodermal Dysplasia
Background:
- Ectopic sebaceous glands (ESGs) are typically found in tissues of ectodermal origin.
- Their occurrence within the esophagus is exceptionally rare, representing a significant anomaly.
Observation:
- This study presents two novel cases of ectopic sebaceous glands identified in the esophageal lining.
- Diagnosis was confirmed via endoscopic biopsy, a standard procedure for esophageal tissue examination.
Findings:
- The presence of ectopic sebaceous glands in the esophagus was definitively established in both reported cases.
- Histopathological analysis of biopsy samples confirmed the diagnosis, characterizing the aberrant glandular structures.
Implications:
- These findings contribute to the limited existing literature on esophageal ectopic sebaceous glands.
- Increased awareness may improve diagnostic rates for this rare esophageal condition, potentially impacting patient management.

Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine glands...
