Invasion of the thoracic duct by postlaryngectomy stomal recurrence: a case report

BACKGROUND: Postlaryngectomy stomal recurrence can infiltrate the adjacent tissues of tracheal stoma. However, to the best of our knowledge, there is no report about postlaryngectomy stomal recurrence invading the thoracic duct with intra-mass accumulation of chylous fluid. CASE PRESENTATION: Our patient was a 52-year-old Han man who presented with a cystic-solid mass on the left side of the tracheal stoma after total laryngectomy. A diagnosis of postlaryngectomy stomal recurrence was confirmed by fine-needle aspiration and surgical dissection of the parastomal mass. CONCLUSIONS: In the case of parastomal masses in a total laryngectomized patient, the rare differential diagnosis of postlaryngectomy stomal recurrence invading the thoracic duct with intra-mass accumulation of chylous fluid should be considered a possibility.
