Mediastinal ganglioneuroma is infrequently encountered in childhood. The posterior mediastinal ganglioneuroma which extended the contralateral thorax was very rare. A 4-year-old boy had a ganglioneuroma which involved bilateral thorax and encased the aorta and azygous vein and the ganglioneuroma was successfully extirpated by two-staged operations.; left thoracotomy first right thoracotomy 10days later.

Ganglioneuroma is a well-differentiated, benign tumor of the sympathetic nervous system. These tumors belong to a family of neoplasm that exhibit a wide range of differentiation, with neuroblastoma at one end and ganglioneuroma at the other. Because it share morphologic features with other both benign and malignant neural tumors, accurate preoperative diagnosis is often difficult. Nonetheless, it is critical for proper management. Fine needle aspiration cytology (FNAC) in the diagnosis of the ganglioneuroma has been a little documented. We describe a case of mediastinal ganglioneuroma in a 33-month-old girl. The diagnosis was suggested on FNAC and was confirmed by histopathologic examination later.

Ganglioneuroma of the gastrointestinal tract is a rare tumor that consists of ganglion cells, nerve fibers, and supporting cells of the enteric nervous system. Ganglioneuromas are usually associated with genetic disorders such as the multiple endocrine neoplasia syndrome or neurofibromatosis. Ganglioneuromas of the gastrointestinal tract predominantly involve the colon and rectum, and reports about duodenal ganglioneuromas are few. Herein, we report a case of duodenal ganglioneuroma treated with endoscopic resection. A 56-year-old female patient visited our hospital because of a subepithelial tumor in the second portion of the duodenum. She had no remarkable medical or family history and revealed no history of genetic disorders. Endoscopic ultrasonography and abdominal computed tomography revealed a tumor located mainly in the submucosal layer, without any regional lymph node involvement. Endoscopic resection of the lesion was performed, and the pathological examination confirmed a duodenal ganglioneuroma.

Ganglioneuromas are a fully differentiated tumor that contains no immature elements. The majority of sanglioneuromas are diagnosed in patients older than 10 years and are most often located in the posterior mediastinum, followed by the retroperitoneum. The location of these tumors in the parapharyngeal region is extremely uncommon and there are only a few reports on the cytologic appearance of the tumor. We report a case of ganglioneuroma presenting in a parapharyngeal location in a 4 year-old boy, diagnosed by fine needle aspiration cytology. The smears revealed scattered large oval to polygonal cells with voluminous, granular cytoplasms. The nuclei were one to two in number and had a prominent nucleolus. Clusters of benign spindle-shaped cells were also present.

Ganglioneuroma (GN) is a rare benign tumor of neural crest origin usually found in the abdomen, but may occasionally present at uncommon sites including the cervical, lumbar, or sacral spine. However, GNs of thoracic spine are extremely rare. In this report, we describe a 12-year-old girl with giant GN in the thoracic spine, who underwent successful resection (T1-4 level) of the tumor. Histopathological examination confirmed the diagnosis. GN should be considered in the differential diagnosis of any paraspinal mass. A high index of suspicion and correlation of clinico-radiological findings is necessary in differentiating a large benign tumor from a malignant growth. Complete surgical excision is the treatment of choice; however tumor size and location need to be considered for the surgical approach (one-step or multiple surgeries). Close follow-up after surgery is mandatory.

Purpose: Ganglioneuromas are well-differentiated tumors derived from neuroectodermal neural crest cells. Although these tumors can occur anywhere along the sympathetic chain from the base of the skull to the pelvic cavity, they usually develop in the posterior mediastinum and retroperitoneum these tumors are rarely found in the cervical region. Method: We report the case of a 16-year-old male patient with neurofibromatosis type 1 who was admitted because of a palpable mass centrally located on the left side of the neck. A preoperative contrast-enhanced neck computed tomography image showed a low-density homogeneous mass on the parapharyngeal space along with marked displacement of the trachea and carotid vessels. Round and soft masses were also detected on both axillae. Results: The patient subsequently underwent complete excision of the neck mass via the transcervical approach. The mass was smooth and well encapsulated between the sternocleidomastoid muscle and the trachea. Further, the mass appeared to arise from the cervical sympathetic chain, which was preserved during surgery. Both the axillary masses were also excised. The histopathological findings were ganglioneuroma for the neck mass and neurofibroma for both the axillary masses. Conclusion: Cervical ganglioneuromas are rare tumors that present as enlarging parapharyngeal cervical masses in the oropharynx or neck. To our knowledge, a case of cervical ganglioneuroma associated with neurofibromatosis type 1 has never been reported. In patients with neurofibromatosis, multiple tumors may develop, and therefore periodic clinical and radiological follow-up is recommended. Further, repeated imaging analysis should be performed if the presence of another tumor is suspected.

Harlequin syndrome is a rare disorder of the sympathetic nervous system characterized by unilateral facial flushing and sweating. Although its etiology is unknown, this syndrome appears to be a dysfunction of the autonomic nervous system. To the best of our knowledge, thus far, very few reports on perioperative Harlequin syndrome after thoracic surgery have been published in the thoracic surgical literature. Here, we present the case of a 6-year-old patient who developed this unusual syndrome following the resection of a posterior mediastinal mass.

Ganglioneuroma (GN) is benign neurogenic tumor arising from ganglia of the sympathetic nervous system. They are mostly found at posterior mediastinum, retroperitoneum, and adrenal gland, whereas only 1-5% occurred in the cervical region. GN usually present as a single, painless and slow-growing mass, but multiple cervical occurrences are extremely rare. An 80-year-old woman came to our clinic complained of posterior neck mass for three years. We performed surgical excision, and it was finally diagnosed as GN. We report the unique and rare disease entity with a brief literature review.

거대세포종은 늑골에서 드물게 발생할 수 있으며, 후중격에서 발생한 종괴로 나타난 늑골의 거대세포종은 지금까지 4 예가 보고되었다. 38세 남자의 늑골에서 발생하여 후중격 종괴로 보인 거대세포종 1 예를 문헌 고찰과 함께 보고한다. 흉부 전산화 단층 촬영에서 우측 후상부 중격의 대부분을 차지하는, 경계가 명확한 다분엽성의 종괴가 우측 3번 늑골과 흉추를 침범하고 있었다. 임상적으로는 후중격에서 발생한 신경절신경종 혹은 그와 동반된 악성 변화를 의심하였다. 그러나 육안적으로 종괴는 우측 3번 늑골에서 발생하여 늑골 바깥쪽으로 성장하는 모습을 보였고, 현미경적으로 균일하게 산재된 다핵 거대 세포와 단핵 기질 세포로 구성되어 있어 늑골에서 발생한 거대세포종에 합당하였다. 거대세포종의 치료를 위해서는 재발과 전이의 가능성을 고려하여 광범위한 수술적 절제와 술후 방사선 치료를 고려해야 한다. 후중격 신경절신경종은 수술적 절제만으로 치료가 가능한 종양이므로, 거대세포종과 반드시 감별해야 한다.

Neurogenic tumors of the mediastinum may have an intraspinal component connected by a narrowed segment of tumor in the intervertebral foramen, then have symptoms of back pain,lower extremity tingling sensation. CT scan or MRI demonstrated a Dumbbell-shaped mass density compressing spinal canal, enlargement of the foramen, erosion of bone, and intervertebral widening. We report the analysis of the 18 cases of neurogenic tumors on posterior mediastinum and Dumbbell type tumors are 3 cases among the 18 cases. The neurilemmomas were 12 cases[67%], the ganglioneuroma were 5 cases[28%], and neuroblastoma was one case[5%]. The successful removal was done in all cases, a standard thoracotomy and laminectomy was done in Dumbbell type tumors.There was no postoperative neurological complications.
