Gland Attenuation, a Novel Morphological Feature of Colorectal Cancer: Evidence for an Epithelial-Mesenchymal Transition.

Ann Coloproctol 2018 Aug 31;34(4):187-196. Epub 2018 Aug 31.

Department of Pathology, Eulji University School of Medicine, Daejeon, Korea.

Purpose: Along the invasive margin, colorectal cancer may show distinctive morphologic changes characterized by an asymmetrically attenuating tumor gland with loss of polarity. The author coined the term 'gland attenuation (GA)' for these peculiar changes. The aims of this study were to compare the immunoreactivity of the epithelial-mesenchymal transition (EMT) markers E-cadherin and β-catenin and thus determine whether EMTs occurs at tumor budding (TB) or GA sites and to assess the association of TB and/or GA levels with clinicopathological parameters and prognosis.

Toxocara canis Mimicking a Metastatic Omental Mass from Sigmoid Colon Cancer: A Case Report.

Ann Coloproctol 2018 Jun 30;34(3):160-163. Epub 2018 Jun 30.

Department of General Surgery, Gyeongsang National University Hospital, Gyeongsang National University School of Medicine, Jinju, Korea.

Toxocara canis is an important roundworm of canids and a fearsome animal parasite of humans. Human infections can lead to syndromes called visceral larva migrans (VLM), ocular larva migrans, neurotoxocariasis, and covert toxocariasis. VLM is most commonly diagnosed in children younger than 8 years of age, but adult cases are relatively frequent among those infected by ingesting the raw tissue of paratenic hosts in East Asia.
