Objective:
To report an extremely rare and interesting case of a woman who developed a laryngeal stone.
Case Report:
A 44-year-old woman was referred to our ENT clinic complaining of dyspnoea and stridor. She had been treated for chest problems for approximately 30 years. On examination, she had a large, spiky, subglottic lesion compromising the airway. A laryngeal computed tomography scan and histopathological and biochemical examination showed the lesion to be a calcium phosphate stone. Review of the literature from the past 50 years, using several search engines, revealed no similar cases.
Conclusion:
To the author's knowledge, this is a unique case of a stone that developed in the subglottis. This rare entity was the cause of long-standing chest problems unresponsive to medical treatment. The patient recovered completely from all her symptoms after removal of the laryngolith.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
