[Inflammatory fibroid polyp: a report of three cases including an oesophageal tumor].

We report three different cases in location with an original occurrence in the oesophagus. The gross appearance showed polypoid pedonculated masses with a whitish cut surface, arising from the submucosa. On microscopic examination, the tumor consisted of spindle cell dispersed in a loose fibromyxoid stroma containing numerous blood vessels and inflammatory cells with abundant eosinophils. At immunohistochemistry, the cells were strongly positive for CD34. Inflammatory fibroid polyp is a rare benign lesion of the gastro-intestinal tract. The pathogenesis of this lesion remains throat and unclear. Diagnosis on biopsy is difficult with various histologic pattern and because the inflammatory fibroid polyp share common pathologic features with digestive spindle cells tumor.
