OBJECTIVE To determine the presentation, pathologic features, treatment outcome, and prognosis of mucoepidermoid carcinoma of the parotid gland in children. DESIGN Retrospective clinical and histopathologic study with institutional review board approval. SETTING Tertiary pediatric medical center. PATIENTS Seven children (4 girls and 3 boys) presented with mucoepidermoid carcinoma of the p...
Introduction: Rhabdomyosarcoma is the most frequently occurring intrusive soft tissue sarcoma in the pediatric age group. Orbit is the most common location for a pediatric rhabdomyosarcoma, but it can occur in the oral cavity, pharynx, face and neck in the descending order of incidence. Rhabdomyosarcoma in the ear is extremely rare. Case Report: A 5-year-old girl prese...
BACKGROUND AND PURPOSE Thyroglossal duct cyst remnants (TGDC) are a common midline neck mass that is mostly encountered in childhood. Enlargement after an upper respiratory tract infection or, rarely, cancer within TGDC, is a well-documented phenomenon. In the pediatric population, it rarely presents a diagnostic quandary. However, in an adult population, especially one treated for head and nec...
Introduction: Papillary thyroid carcinoma (PTC) constitutes 75–85% of all thyroid cancers. PTC usually presents as a subtle, commonly slow-growing, painless thyroid mass or a solitary nodule in the neck. This presentation of a cystic neck lump, without the presence of a thyroid nodule, may imitate the course of a benign disease, thus delaying diagnosis and proper treatment. Case Report: Thr...
Pilomatricoma, although rare, is the second most frequent benign skin tumor in childhood. It is a hard, painless, slowly progressing subcutaneous tumor that is commonly located in the head-neck region, especially periorbital, and in the upper extremities. Histopathologic characteristics are distinctive. In this study, we performed a retrospective review of the records of our pediatric patients ...
Pediatric neck masses comprise a wide spectrum of entities, benign and malignant. The role of imaging is to characterize these lesions, in order to better determine which can be expectantly managed and which require immediate intervention. An important consideration in the pediatric population is ionizing radiation; while X-ray and CT can be useful, radiation can have harmful effects, particula...
BACKGROUND The thymus develops from the third pharyngeal pouch and descends from the neck into the anterior-superior mediastinum. Thus, it is possible to have thymic remnants in the neck, which most often present as a cervical mass during childhood. One type of cystic thymic remnant is the thymopharyngeal duct cyst, a remnant of one of the paired tracts of embryological thymic descent. Thymopha...
Introduction: Extracranial meningioma is a rare tumor which is located in middle ear, temporal bone, sinonasal cavity, oral cavity, parotid gland and soft tissue of head and neck. Case Report: The case of the present study was a 67-year-old male patient who referred with pain complaint during flexion of neck from 5 years ago and palpable mass in posterior neck triangle from 2 years ago. Con...
Head and neck trauma in pediatric population differs from adult cases due to the immature cranio-cervical stability resulting from the weak neck musculature and large head to neck proportion. These cases also have drawn attention due to concomitant severe damage to the regional vascular structures such as carotid artery [1,2]. In some cases, especially with skull base fractures and cervical ver...
