[Ankylosing hyperostosis Forestier, simulating a neoplasm of the larynx].

Relevance: Forestier syndrome, despite its appearance as an independent disease in the 60s of the last century, remains as difficult to diagnose. This is due to a number of factors: age group, late treatment, insufficient knowledge of pathology. The timely detection of pathology is complicated by the similarity of the clinical picture in the early stages of its manifestation with a number of orthopedic diseases.

Objective: To present a description of the clinical observation of Forestier syndrome.

Material And Methods: The material for this work was a clinical case of a person who applied to the Loginov Moscow Clinical Scientific Center with a directional oncological diagnosis of the larynx and a preemptively installed tracheostomy.

Results: The patient underwent surgical treatment in the form of removal of overgrown bone osteophytes of the thoracic spine with simultaneous disappearance of symptoms of the disease.

Conclusion: This clinical observation clearly demonstrates the need for a comprehensive analysis of the clinical situation as a whole with a careful assessment of all factors that can influence it and the process of forming a diagnosis. Knowledge of conditions that can mimic a tumor lesion is extremely important for oncologists of all specialties. This allows you to avoid an erroneous diagnosis and choosing the wrong, possibly crippling treatment tactics. It should also be remembered that the oncological diagnosis is based, first of all, on morphological confirmation of the tumor process with a detailed assessment of the data of all additional imaging research methods.
