Primary tracheal tumors are a rare disease, accounting for 0.89% of primary lung tumors. In particular, tracheal leiomyomas have been reported to account for about 1% of primary tracheal tumors and are an extremely rare disease. Leiomyomas most frequently arise in the uterus or alimentary tract and rarely occur in the head and neck region. We report on a case of subglottic leiomyoma of the trachea.
A 64-year-old woman presented with dyspnea. Laryngeal fiberoscopy and computed tomography (CT) showed a subglottic tumor. After tracheostomy, we reached a diagnosis of leiomyoma based on laryngoscopic biopsy findings. The tumors were removed via a laryngofissure and no recurrence was seen after the operation. The histopathological diagnosis was a leiomyoma. At the time of writing, more than 4 years have passed since the surgery, without recurrence. We had exenterated the subglottic tracheal leiomyoma safely.
Because it is important to choose the surgical procedure according to the size of the lesion and the pedicle, together with the site of tracheal leiomyomas, we present our case with some discussion and a review of the relevant literature.
