Primary glomangioma of the esophagus mimicking esophageal papilloma.
Diseases of the Esophagus, 19 (3).
We report a case of glomangioma of the esophagus in a 28-year-old woman who presented with a 3-year history of vague discomfort, pain and heat in the neck. At initial gross examination, the tumor mimicked an esophageal papilloma. The resected esophageal specimen contained a polypoid, whitish-gray mass, which measured 3 cm in maximum diameter. Microscopically the tumor consisted of loose fibrovascular stroma heavily infiltrated with mononuclear inflammatory cells and covered with focally hyperkeratotic, parakeratotic and acanthotic squamous epithelium without atypia. In the deeper area immediately above the true muscular layer of the esophageal wall, microscopical examination revealed the neoplasm consisting of numerous, small-to-medium branched vessels covered by regular endothelium and filled with erythrocytes. The loose stroma around the vessels contained poorly circumscribed nests of small, round to oval cells with a uniform appearance. Immunohistochemically, the tumor cells were immunoreactive for smooth muscle actin and vimentin and non-immunoreactive for CD34, CD117, desmin, pan-cytokeratin, synaptophisin, neuron-specific enolase and S-100 protein. Despite its bland histology, the infiltrative growth pattern was suggestive of aggressive behavior; thus, an appropriate clinical follow-up was recommended. An accurate diagnosis and an understanding of the behavior of these rare tumors, especially in an unusual location, are crucial to their management and clinical outcome.
