Infected Thyroglossal Duct Cyst in a Neonate: A Report of a Rare Case.

BACKGROUND Thyroglossal duct cysts are the most common congenital cervical anomalies, often presenting as midline neck cysts. The mean age of presentation of pediatric thyroglossal duct cysts varies between 5 and 9 years old, with rare cases younger than 1 year old. This case report details a rare case of an infected thyroglossal duct cyst presenting during the neonatal period as an upper airway obstruction. CASE REPORT A 3-week-old neonate born full-term with no complications during pregnancy or labor presented with a 5-day history of worsening nasal congestion and upper airway obstruction after an upper respiratory infection. Physical examination revealed a large midline neck mass measuring 3.1×4.2×3.2 cm abutting the hyoid with internal echogenicity consistent with a thyroglossal duct cyst, causing posterior tongue compression of the airway and airway distress. The patient was emergently taken to the operating room for incision and drainage, where she underwent a difficult intubation due to superior-posterior tongue displacement and global supraglottic edema. She was discharged on postoperative day 5 on a course of Augmentin after cultures grew methicillin-sensitive Staphylococcus aureus. The patient had no further complications, with successful excision using a Sistrunk procedure 6 months later. CONCLUSIONS Pediatric thyroglossal duct cysts most often present as an asymptomatic midline neck mass, with rare sequelae of infection and upper airway obstruction. This case report highlights the pathophysiology and presenting symptomology of thyroglossal duct cysts, explores the rarity of infected thyroglossal duct cysts in neonates, and reviews the current literature on management strategies for these patients.

Superior Vena Cava Syndrome in an Infant: A Case of Delayed Diagnosis.

This case presents an infant boy with neonatal respiratory distress and sepsis, who was eventually diagnosed with and treated for superior vena cava (SVC) syndrome after three months of fluctuating head and neck edema. While SVC syndrome is uncommon in pediatrics and is usually caused by malignancy-associated external compression, the growing use of central venous catheters in these patients makes catheter-related thrombosis a potential cause of this serious complication. This case of delayed diagnosis highlights the importance of investigating SVC syndrome as a potential cause of respiratory distress and edema in any patient with a history of central venous catheter placement or similar procedures.

Balloon dilation causing tracheal rupture: Endoscopic management and literature review.

A 72-year-old female with a history of idiopathic subglottic tracheal stenosis suffered tracheal rupture during endoscopic balloon dilation. The defect measured 7.5 cm in length, through which the mediastinum was visualized. An 80 × 20-mm silicone-covered tracheobronchial stent was deployed over the defect. The patient was extubated subsequent to intraoperative computed tomography demonstrating minimal air escape. Postoperatively, the patient saw no further complications and was discharged 3 days later. The stent was removed 80 days postoperatively revealing healed trachea. Tracheal rupture is a potential risk of balloon dilation, and the list of possible complications is extensive and morbid. Although traditional repair requires an open approach, endoscopic techniques are growing in description, and tracheal stenting was successful in this case. Laryngoscope, 126:2774-2777, 2016.

Primary mucosal desmoplastic melanoma of the nasal vestibule: the second case.

Primary mucosal desmoplastic melanoma is an exceedingly rare, potentially devastating disease that is often initially misdiagnosed because of its deceptively benign presentation. We report what we believe is only the second case of mucosal desmoplastic melanoma arising from the nasal vestibule. The patient, a 62-year-old woman, presented with an obstructive, enlarging mass in the nasal cavity. The tumor, which was initially believed to be benign, was excised, but it recurred 12 months postoperatively. The recurrence was excised, but 4 years later, the patient experienced a second recurrence; in this case, the tumor had invaded the cribriform plate and extended to the anterior cranial fossa. The tumor subsequently metastasized to the dura mater, which led to the patient's death. We review the distinction between conventional mucosal melanoma and mucosal desmoplastic melanoma, and we discuss the ways in which the behavior of a desmoplastic melanoma can point to the diagnosis. Because a diagnosis can be difficult to establish, we stress the importance of maintaining a high index of suspicion when evaluating pathologic and immunohistochemical findings in a patient with a recurrent mucosal nasal mass.
