Abstract:
A 44-year-old male was followed-up with esophagogastroduodenoscopy due to an esophageal submucosal tumor. On the lesser curvature of the gastric low body, a 0.5 cm sized round elevated lesion with hyperemia was noticed. Two pieces of biopsy were taken from this lesion for histopathologic examination. Histology showed Langerhans cell infiltration. Immunohistochemical staining was positive for CD1a antigen, which confirmed the diagnosis of Langerhans cell histiocytosis. There was no evidence of other organ involvement. The lesions spontaneously disappeared 4 months later without any treatment. We report a very rare case of gastric Langerhans cell histiocytosis.
