Atypical carcinoid tumour of the larynx treated with CO2 laser excision: case report.
A case of atypical laryngeal carcinoid tumour of the right aryepiglottic fold is described in a 56-year-old female. The patient presented a 4-year history of dysphagia, occasional dyspnoea and pain originating in the right tonsillar fossa and radiating to the ear. A sessile, submucosal neoplasm of about 1 cm in diameter and apparently benign appearance was detected endoscopically in the supraglottic region. An excisional biopsy was collected by CO2 laser during direct microlaryngoscopy from which a diagnosis of atypical carcinoid tumour of the larynx was made, and later confirmed by histochemical and immunohistochemical staining. Post-operative course was uneventful, with return to a normal diet per os on the first post-operative day. Histopathological evaluation of the excised specimen revealed the presence of a neoplasm in proximity of the surgical margins, which were not, however, directly involved by the tumour. The close endoscopic follow-up was, nonetheless, implemented in order to promptly detect any evidence of relapse of the disease. After 18 months, a lesion, suspected of being a recurrence, was found, in the site of the original tumour. CO2 laser excision was again carried out, this time allowing for wider margins on the surgical resection. The post-operative diagnosis confirmed the clinical hypothesis of recurrence of atypical carcinoid tumour. The patient is presently alive and free from disease 7 years after the second endoscopic procedure. The difficult aspects of clinical and histopathological diagnoses, the surgical treatment as well as endoscopic and instrumental follow-up of this rare condition are discussed.
