Foreign body inclusions in colonic polyps are rarely reported in the literature and we present a case of tomato seed inclusion in an adenomatous polyp.

A 52-year-old woman with a history of rectal bleeding was admitted to our hospital. Colonoscopy revealed two polypoid lesions: A pedunculated one, with a diameter of 1.2 cm and a sessile one with a 1 cm diameter, located at 35 cm from the anal verge. Both lesions were histologically diagnosed as tubular adenomas with moderate epithelial dysplasia (LGD-low grade dysplasia).

In the pedunculated adenoma, the macroscopic examination of the specimen revealed a whitish round-oval area of 2-3 mm in diameter, superficially on the sagittal section.

Microscopically, we noticed an oval structure limited by a clear-cut membrane, with a fuzzy aspect, which included some spiral tubes filled with numerous eosinophilic, erythrocyte-like inclusions [Figure 1] and [Figure 2].

The image resembles a parasite but the parasitological examination did not certify a specific pathogen. Trying to identify vegetal aspects, we included some seeds in paraffin and we noticed an identical microscopical aspect when analyzing tomato seeds (Lycopersicon esculentum) [Figure 3].

   Discussion Top

The case we present shows a foreign body with pseudo-parasitic or pseudoparasitic features turning out to be a vegetal body included in the superficial area of an adenomatous colonic polyp. In literature only a few cases with foreign body inclusions in colonic polyps were described, namely silk suture and parasitic larvae. [1],[2] Other reports in literature, that link colonic polyps to seeds, are cases of radiological findings in which corn kernels and linseeds mimic multiple polyposis. [3],[4] Velanovich [5] described a case of vegetable seed surrounded by inflammatory tissue, mimicking a 4 mm colonic polyp in a 54-year-old female patient with hematochezia but histological pictures of the lesion were not presented.
