Langhansa Struma

**Langhans struma** Langhans strumas belong to the category of epithelial tumors of the mediastinum. These neoplasms do not resemble ordinary epithelial tissue and are of ectodermal origin. The name of this tumor comes from the name of the scientist David Langhans, and is currently considered synonymous with the term langhasamidatoraxia. The history of the disease, for the most part, is marked by increased attention of pediatric surgeons in the 50-60s of the 20th century, there were pronounced cases of their prevalence due to previous treatment of thyroid cancer with radioactive iodine.

Langhans-like tumors of the mediastinum are a fairly rare category of neoplasms of the mediastinal space, their frequency is 0.8-2% of all tumor processes in this localization. Men and women are equally susceptible to developing LCHOS.

The average age of patients was 30-40 years, while acute forms of the disease were often encountered in children and adolescents. Based on this, it can be assumed that the exogenous type of tumors predominates. Symptoms of the disease: painful sensations of varying intensity are noted in the sternum and above the shoulder girdle, pressure and compression are felt in the neck, brachialgia and intercostal pain. Inspiratory dyspnea is also often detected. With a sharp attack of pericardial syndrome, paradoxical breathing with whistling and noise is observed. Frequent symptoms of the pathology are changes in blood pressure and arrhythmia. Discharge of blood from the mouth and nose is a very rare occurrence, most likely associated with a traumatic effect on the tumor nodes. Paracervical pain and difficulty swallowing, compression of the esophagus and trachea are accompanied by severe cough and dysphagia. The course of Langhans struma is often accompanied by ectopic production of thyroid hormones. It is worth noting that it can replace functioning tissue without causing destructive changes. Local indicators of active inflammation are the appearance of cough with sputum, wheezing and bronchospasm. Conversely, LCHOS without signs of inflammation is often not accompanied by hormonally active processes or their unhealthy dynamics. Adults suffer from this disease much less frequently than children and adolescents. It should be clarified that from the first days of the appearance of LCHOS, blood and urine indicators indicate a clear inflammatory picture. Serum eosinophil levels exceed 1%.
