Barre-Masson Tumor

Barre Masonic Tumor

Barr Masonic tumor (BMTS) is a rare tumor that originates from the squamous epithelium of the apical zone of the allantois and placenta or the lining of the blood vessels of the umbilical cord and other nodes of the embryonic membranes. Develops mainly in the first half of pregnancy. More often observed in girls.

The morphological signs of the tumor are varied: cysts, various types of polyps, solid poorly differentiated areas of the mucous membrane, giant cells, areas of narrowing of the lumen of the cervical canal with papillomatous growth. Massive areas of neoplasia can fill the entire lumen of the cervix, then the last stages of pregnancy and childbirth occur as spontaneous abortions, accompanied by bleeding.

The incidence of BSMO is 0.19 cases per 1,000

Barre-Masson oncological disease, in honor of the French scientists who studied it.

**Barre - Massano disease**, or barium colitis disease **Barre**. Discovered by French doctors Barre (1879-1972) and Masson (1890-1840), described in 1911. Bulimia (a constant feeling of hunger) is the cause of the transition from bulimia to psychogenic stage bulimia and further to dementia with barium stomach disease or barium diarrhea. Barium disease Antestrodan is also known as interventional disease or psychogenic bulimia, along with barium disease of the stomach. The first is a psychogenic eating disorder, which begins when someone begins to eat abnormally large amounts of food and reaches an alarming quality of eating. The result is usually a desire to get rid of nausea and hypersensitive appetite. Typically, this problem suddenly ceases to exist after stopping the use of psychoactive substances. The causes of bilination or nausea are unknown. Billing is an intestinal infection caused by the Coxsackie virus, causing stomach pain and muscle pain.
