Carcinoma of duodenal bulb arising from the Brunner's gland

Gastroenterologia Japonica
M ItsunoH Watanabe


A 75-year-old man was diagnosed as having a sessile tumor measuring 1.4 x 1.0 cm in size in the duodenal bulb after upper gastroduodenal series. The biopsy specimens revealed a proliferation of the adenomatous glands showing an acinar structure with papillary infolding; type III mucus, which is characteristic of Brunner's glands. Antral glands and mucus neck cells of the fundic glands were also observed in the adenomatous glands by concanavalin A staining. Thus, it was clear that the tumor had originated from the Brunner's glands. Three years and four months later, the sessile tumor had developed into a fungating ulcerated tumor via a polypoid form. The biopsy specimens revealed a papillary adenocarcinoma with foci of undifferentiated carcinoma. Retrospectively, the adenomatous glands in the biopsy taken from the sessile tumor should have been regarded as low grade carcinoma. Therefore, we propose that when a polyp or tumor shows an increase in size or change in macroscopic appearance, surgery should be considered.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
