Palpable pediatric thyroid abnormalities – diagnostic pitfalls necessitate a high index of clinical suspicion: a case report
A 12-year-old girl presented with a 4 year history of an enlarged, firm thyroid gland. On exam, her thyroid was firm and fixed and an enlarged cervical lymph node was palpable as well. Though a thyroid ultrasound prior to referral was read as thyroiditis, clinical suspicion for thyroid carcinoma mandated continued investigation. The diagnosis of papillary thyroid cancer was established and her workup revealed lymph node metastases as well as a tremendous burden of pulmonary metastases. Pediatric thyroid cancer is extremely rare, but often presents with aggressive disease. Palpable thyroid abnormalities in an individual under 20-years-old should be viewed with suspicion and should be thoroughly investigated to rule out malignancy even in the face of negative diagnostic procedures. Though pediatric papillary thyroid cancer often presents with loco-regional and even distant metastatic disease, mortality rates in follow-up for as long as 20 years are very favorable
Prognostic Factors and Survival in Pediatric and Adolescent Liposarcoma
Purpose. Liposarcoma is extremely rare in the pediatric population. To identify prognostic factors and determine treatment outcomes, we reviewed our institutional experience with pediatric liposarcoma. Methods. We retrospectively reviewed all pediatric patients (age < 22 years) with confirmed liposarcoma treated at Memorial Sloan-Kettering Cancer Center. Histologic subtype, tumor location, margin status, recurrence, and adjuvant therapy were analyzed and correlated with overall survival. Results. Thirtyfour patients (56% male) with a median age of 18.1 years were identified. Twenty-two (65%) had peripheral tumors and 12 (35%) had centrally located tumors. Histologically, 29 (85%) tumors were low grade, and 5 (15%) were high grade pleomorphic. Eleven (32%) had recurrent disease, 9 patients with central tumors and 2 patients with peripheral lesions. Eight deaths occurred, all in patients with central disease. Five-year overall survival was 78%, with a median follow-up time of 5.4 years (range, 0.3-30.3 years). Tumor grade (P = .003), histologic subtype (P = .01), and primary location (P < .001) all correlated with survival, as did stage (P < .001) and margin status (P = .001). Conclusions. Central location of the primary tumor, high tumor grade, and positive surgical margins are strongly correlated with poor survival in pediatric patients with liposarcoma
Gastric volvulus following left pneumonectomy in an adolescent patient
Gastric volvulus is a rare post-pneumonectomy complication. Although it has been described previously, published cases are limited to an older patient population. We report the youngest case of postpneumonectomy gastric volvulus to date, occurring in an 18-year-old male with a history of inflammatory myofibroblastic pseudotumor who underwent left intrapericardial pneumonectomy, and presented 13 years later with chronic intermittent mesenteroaxial gastric volvulus. While postpneumonectomy gastric volvulus is a rare occurrence, it should remain in the differential diagnosis in postoperative thoracic surgical patients presenting with chest pain

Desmoid Tumors in the Pediatric Population
Desmoid tumors are benign soft tissue tumors associated with locally aggressive growth and high rates of morbidity, but they do not metastasize via lymphatic or hematogenous routes. While most of the data on desmoid tumors originates in the adult literature, many of the findings have been applied to the management of pediatric patients. This article discusses the epidemiology, etiology, clinical presentation, pathology, and treatment of this rare tumor in the pediatric population and includes a literature review of the most recent large series of pediatric patients with desmoid tumors
