A five month female was referred complaining of intermittent vomiting with protrusion of a sausage-like mass through the oral cavity. Esophageal endoscopy and esophagogram revealed a mass in the upper esophagus, which was diagnosed as a fibrovascular polyp. Under general anesthesia, the mass was grasped through the oral cavity with a forcep and ligated and excised at the base, where a stump arose from the posterior wall of the cervical esophagus. The pathology was confirmed as a fibrovascular polyp, which is a rare benign esophageal lesion occurring mostly in adult males, and has not been reported in infancy.

Colonic arteriovenous malformation (AVM) is one of the causes of lower gastrointestinal bleeding. Unlike small vascular ectasia or angiodysplasia, colonic AVM tends to be solitary, large in size, and identified endoscopically as flat or elevated bright red lesion. Herein, we report a case of non-solitary and small cecal AVMs which were removed by endoscopic biopsy. A 66-yr-old woman was referred for routine gastrointestinal cancer screening. She was suffering from diabetes, hypertension, end-stage renal disease, and anemia of chronic disease. On colonoscopic finding, three semi-pedunculated polyps, less than 5 mm in size, were noticed near to the appendiceal orifice. Since the lesions revealed normal-looking epithelium with converging folds on the cecal base, lesions were diagnosed as inflammatory polyps on gross finding. Three biopsies were taken from each lesion. Bleeding from the biopsied site ceased spontaneously. Histopathologic evaluation demonstrated intramucosal hemorrhage and dilated submucosal vessels which were consistent with polypoid colonic AVMs.

The hamartomatous polyps in Peutz-Jeghers syndrome may have malignant potential. To differentiate between hamartomatous and adenomas polyps, vascular characterization can be assessed using noninvasive procedures, such as contrast-enhanced ultrasound (CEUS). The neo-angiogenic characteristics of colorectal adenomas and carcinomas are expressed as an anarchic vascular pattern observed on CEUS. Using CEUS in a patient with Peutz-Jeghers syndrome, we describe for the first time the vascularization of a hamartomatous colonic polyp that exhibits a hierarchy branching pattern.

PURPOSE: To evaluate 12-month outcomes of anti-vascular endothelial growth factor (VEGF) therapy for polypoidal choroidal vasculopathy (PCV) with grape-like polyp clusters. METHODS: This retrospective observational study included 23 eyes of 23 patients who were newly diagnosed with PCV with grape-like polyp clusters, and who were subsequently treated with anti-VEGF monotherapy. The study compares the best-corrected visual acuity (BCVA) of the patients at diagnosis, at 3 months, and at 12 months after diagnosis. In addition, 12-month changes in BCVA values were compared between cases with subfoveal or juxtafoveal polyps and cases with extrafoveal polyps. RESULTS: The baseline, 3-month, and 12-month logarithm of the minimal angle of resolution BCVA was 0.62 ± 0.35, 0.50 ± 0.43, and 0.58 ± 0.48, respectively. Compared to the baseline, patient BCVA was not significantly different at 12 months after diagnosis (p = 0.764). Six eyes (26.1%) gained ≥0.2 logarithm of the minimal angle of resolution BCVA. In cases with subfoveal or juxtafoveal polyps, BCVA values at baseline and at 12 months after diagnosis were 0.66 ± 0.37 and 0.69 ± 0.53, respectively. In cases with extrafoveal polyps, the values were 0.54 ± 0.33 and 0.37 ± 0.31, respectively. Changes in BCVA values were significantly different between the two groups (p = 0.023). CONCLUSIONS: Although anti-VEGF therapy has favorable short-term efficacy for treating PCV with grape-like polyp clusters, long-term visual improvements are generally limited in the majority of afflicted eyes. The presence of subfoveal or juxtafoveal polyps may suggest unfavorable treatment outcomes.
