Abstract:: Ectopic thymic tissue is an unusual finding that is generally asymptomatic. We present a case series of five pediatric patients with cervical ectopic thymuses. In two patients, the ectopic thymic tissue was symptomatic, and in three patients it was an incidental finding. We highlight the need to include this anomaly on the differential diagnosis for a pediatric neck mass. We also propose observation, rather than surgical excision, as the treatment of choice for asymptomatic cervical ectopic thymus.

CONTEXT: Neuroglial ectopia has been defined as a mass composed of differentiated neuroectodermal tissue isolated from the spinal canal or cranial cavity and remains rare. This lesion has to be considered in the differential diagnosis among newborn infants with classical symptoms of respiratory distress, neck mass and feeding difficulties. We present a rare case of extensive parapharyngeal and skull base neuroglial ectopia in 6-month-old girl who presented respiratory and feeding obstruction at birth. CASE REPORT: A six-month-old girl who presented upper respiratory and feeding obstruction at birth and was using tracheostomy and gastrostomy tubes was referred to our institution. Complete surgical excision of the mass consisted of a transcervical-transparotid approach with extension to the infratemporal fossa by means of a lateral transzygomatic incision, allowing preservation of all vital neurovascular structures. The anatomopathological examination showed a solid mass with nests of neural tissue, with some neurons embedded in poorly encapsulated fibrovascular stroma, without mitotic areas, and with presence of functioning choroid plexus in the immunohistochemistry assay. Neurovascular function was preserved, thus allowing postoperative decannulation and oral feeding. Despite the large size of the mass, the child has completed one year and six months of follow-up without complications or recurrence. Neuroglial ectopia needs to be considered in diagnosing airway obstruction among newborns. Surgical treatment is the best choice and should be performed on clinically stable patients. An algorithm to guide the differential diagnosis and improve the treatment was proposed.

A 55-year-old woman had a right-sided neck mass overlying the angle of the mandible, which proved to be a chemodectoma. The occurrence, differential diagnosis, and relatively high frequency of incorrect preoperative diagnosis of carotid body tumors is reviewed. The essential role of angiography to substantiate the diagnosis is discussed.

Branchial Anomalies

Branchial cleft anomalies are an important differential diagnosis in congenital neck masses in infants. The third and fourth branchial anomalies are rare branchial cleft anomalies, which are hard to differentiate. We report here an uncommon case of the fourth branchial anomaly that was presented as an asymptomatic neck mass in a neonate.

Masson’s tumor, also known as intravascular papillary endothelial hyperplasia (IPEH), is a rare, benign vascular tumor characterized by the proliferation of endothelial cells with papillary formations. Differential diagnosis between IPEH and angiosarcoma is important because both have microscopic similarity. Herein, we report a rare case of IPEH on the right lateral neck of a 50-year-old female presenting with a neck mass, which was completely removed without complication.

A 64-year-old man presented with gross painless hematuria.Cystoscopy revealed a submucosal bladder neck mass coveredby normal urothelium. During transurethral resection, the patientdeveloped hemodynamic crisis including sinus bradycardia.Histopathologic examination revealed a primary bladder compositeparaganglioma-ganglioneuroma (CPG). The patient underwentpartial cystectomy and is symptom-free after one year. BladderCPGs are extremely rare neoplasms that may result in lifethreateningcatecholamine secretion, especially during tumourmanipulation. These tumours require complete surgical excisionand should be included in the differential diagnosis of any solitarybladder mass covered by normal urothelium, especially whenthere is a history of hypertension or micturition attacks.

Recent Origin

Cervical lymphangioma is rare among adults. Thirty-two patients with cervical lymphangioma were treated at the Mayo Clinic between 1950 and 1982. The records of these patients were reviewed to investigate the clinical and pathologic behavior of this lesion in persons more than 16 years of age. The lesions were seen in all decades of adult life and equally in men and women. Most lesions presented as a rapidly enlarging, asymptomatic mass. The anterior triangle of the neck was involved nearly as often as the posterior triangle, and right-sided locations predominated (72%). Histopathologic differentiation of the lesions into simplex, cavernous, and cystic lymphangiomas was not helpful in predicting clinical behavior. Surgical excision is the treatment of choice. The lesions may intimately involve the carotid sheath or adjacent nerves. Recurrence in 21% of the 28 patients on whom follow-up data were available mostly represented incomplete excision. Lymphangioma should be included in the differential diagnosis of a large asymptomatic neck mass of recent origin in the adult.
