Esophageal Pyogenic Granuloma: A Case Report and Review of the Literature

Pyogenic granuloma (PG) is a capillary hemangioma mainly found in the skin and oral mucosa, but rarely described in the esophagus. We report the case of a 66-year-old man who consulted for retrosternal pain. Endoscopic studies showed a 28-mm polypoid mass located at the distal esophageal mucosa. The patient underwent endoscopic resection, and the histopathological examination showed a neoplastic proliferation of small blood vessels growing in a lobular architecture, with edematous stroma and prominent inflammatory infiltrate. Special stains for fungus showed pseudohyphae compatible with Candida spp. Findings were consistent with those of an esophageal PG associated with Candida infection. This case is a reminder that PG can be found in the esophagus, can be associated with other entities such as Candida infection, and is one of the differential diagnoses of neoplastic vascular proliferations that may mimic malignancy. In addition, we reviewed previously reported cases of esophageal PG.

“…Histopathologically, pyogenic granuloma is a hemangioma characterized by a lobule-like growth of capillaries with enlarged vascular endothelial cells and inflammatory cell infiltration in the stroma. Granulation tissue may also be present; the main pathological differential diagnosis of pyogenic granuloma includes bacillary angiomatosis, Kaposi’s sarcoma, or inflammatory and/or hyperplastic polyps 1 3 .…”

“…

Lobular capillary hemangioma, known as pyogenic granuloma, is a benign vascular tumor that generally appears on the skin or in the oral cavity but rarely occurs in the gastrointestinal tract, where it can cause bleeding [1]. Although gastric pyogenic granuloma is rarely reported in the literature, (up to 2016, approximately 50 cases of gastrointestinal pyogenic granuloma in the English literature had been indexed on MEDLINE, including a few cases of gastric involvement), the actual incidence is probably higher [2,3]. The endoscopic appearance of pyogenic granuloma is usually a single polypoid lesion, smooth and ulcerated; the color ranges from bluish to reddish with a superficial white or opaque film covering.

Pyloric outflow obstructions can be caused by several types of lesions. When a thickened gastric wall and pyloric mass are detected, malignant neoplasia must be differentiated from chronic hypertrophic pyloric gastropathy. CT can characterize gastric tumors. However, based on the authors’ review of the literature, there is limited information about the CT findings of pyloric lesions. The purpose of this retrospective case series study was to assess the CT findings of canine pyloric lesions. The following CT parameters were recorded: anatomical area, involved area, lesion shape, growth patterns of wall thickening lesions, enhancement pattern of the lesion in the early and delayed phases, lymphomegaly, and pulmonary metastasis. Seventeen dogs were included in this study and had the following final diagnoses: hyperplasia (five dogs), adenoma (five dogs), adenocarcinoma (three dogs), gastrointestinal stromal tumor (GIST; two dogs), polyposis (one dog), and pyogenic granuloma (one dog). Hyperplasia, adenoma, and polyposis formed mass lesions that involved the mucosal layer. Lymphomegaly was detected in two Jack Russell terriers with hyperplasia; however, the causes were unknown because we did not perform biopsies. All adenocarcinomas formed wall‐thickened lesion that involved the outer layer, with lymphomegaly. All GISTs formed mass lesion that involved the outer layer. The pyogenic granulomas formed symmetric wall‐thickened lesion that involved the mucosal and outer layers. CT facilitated the characterization of canine pyloric lesions using contrast enhancement, based on the involved area and lesion shape. However, polyposis may require caution in diagnosis based on CT findings alone.
