Solitary Submandibular Schwannoma Mimicking a Salivary Gland Tumor in a Child.

Tumors occurring in the submandibular space are infrequent among pediatric patients, and benign peripheral nerve tumors in this region are exceptionally rare. This study describes the uncommon occurrence of a schwannoma in the submandibular space in a child and describes its management. A 7-year-old child presented with a gradually enlarging swelling over a 7-month period in the submandibular region, clinically resembling a salivary gland tumor. There were no associated marginal mandibular, lingual, or hypoglossal nerve palsy. The mass was excised completely, and histopathological examination revealed it to be a schwannoma. It is appropriate to consider benign peripheral nerve tumors, such as schwannoma, in the differential diagnosis of submandibular space tumors in children.

Double-Staged Sleeve Resection of Laryngotracheal Tumor of Papillary and Follicular Thyroid Carcinoma.

Advanced thyroid carcinoma involving the upper aerodigestive tract confers a poor prognosis mainly due to airway complications. The management of thyroid carcinoma with infiltration to the aerodigestive tract has been widely discussed with no consensus regarding the best surgical technique. Complete surgical resection is the aim of the surgery. However, it has high morbidity if the postsurgical care is compromised, which will lead to airway obstruction, bleeding, infection, and anastomotic dehiscence. In our center, complete resection was achieved through cricotracheal window resection with partial closure and tracheostomy tube insertion. This procedure was chosen due to the time-sensitive nature of surgery in these patients with airway compromise and postoperative limitation of intensive care unit (ICU) bed availability. In our case series, we present six cases of papillary and follicular thyroid carcinoma complicated with intraluminal laryngotracheal infiltration and discuss its management and outcome.

Extracardiac Rhabdomyoma Mimicking Plunging Ranula.

Histopathologically adult extracardiac rhabdomyoma is a benign tumour of mature striated muscle. It is a slow- growing tumour with predilection to occur in head and neck region. They appear mainly as a solitary lesion, and about 15% of them can be multicentric. A 56-year-old man presented to us with the floor of mouth swelling persisted for one year and the right neck swelling for three years mimicking a plunging ranula. Radiological imaging revealed enhancing mass at the floor of mouth and submandibular region. The mass represented a nonvascular benign tumour. Subsequently, the patient underwent excision of the mass via transcervical and transoral method. Histopathological examination revealed adult type of extracardiac rhabdomyoma. Adult type of extracardiac rhabdomyoma should be considered in the differential diagnosis for the head and neck masses. A complete excision will reduce the risk of recurrence.
