Laryngeal neuroma in a MEN-2B paediatric patient

Multiple endocrine neoplasia type 2B (MEN-2B) syndrome is a genetic disorder that predisposes to the development of tumours in the mouth, eyes and endocrine glands. It is associated with mucosal neuromas; however, laryngeal mucosal neuromas are very rare. We describe an adolescent with MEN-2B who presented with dysphonia, nocturnal stridor and exertional dyspnoea following a total thyroidectomy for an invasive medullary thyroid carcinoma with right recurrent laryngeal nerve sacrifice.Following initial assessment, laryngeal stroboscopy was performed, followed by a microlaryngobronchoscopy under general anaesthetic. A lesion was identified on the left vocal process that underwent debulking. Histopathological findings were consistent with mucosal neuromas.Laryngeal neuromas are rare in the context of MEN-2B and can pose significant diagnostic challenges, particularly in a patient with other airway pathologies. An awareness of different clinical features of MEN-2B is important to consider in differential diagnoses, and biopsy and histopathological analysis are essential for diagnostic purposes.
