A Case of Lingual Thyroid Presenting with Severe Hematemesis in Pregnancy

Lingual thyroid is a rare anomaly with symptoms such as upper airway obstruction, dysphagia, or hypothyroidism. However, bleeding is a very rare manifestation. This report describes a case of lingual thyroid in women with 28 weeks of amenorrhea and hematemesis, and its course of diagnosis and treatment. The pathogenesis of lingual thyroid is unknown. Although ectopic lingual thyroid is usually not managed surgically, excision of ectopic lingual thyroid can be lifesaving when it is causing bleeding or airway obstruction. However, during pregnancy, surgery is the preferred mode of treatment.
