食管癌颈部巨大囊性淋巴结转移1例报道

临床上由恶性肿瘤淋巴结转移引发的颈部巨大囊性肿物十分少见,尤其是由食管癌引发的双侧颈部巨大囊性淋巴结转移更是罕见,因此极易将其诊断为良性肿物从而误诊误治。本文通过回顾一例以双侧颈部巨大囊性肿物为首发症状就诊后诊断为食管癌颈部囊性淋巴结转移的病例,反思及总结关于颈部囊性肿物的诊疗思路。

Ectopic thymus presenting as a solid submandibular neck mass in an infant: case report and review of literature.

Solid ectopic cervical thymus is an extremely uncommon etiology of a neck mass in an infant. It occurs in the line of descent of the thymus from the angle of the mandible to the superior mediastinum. Nine cases of ectopic cervical thymus in infants have been reported in the literature. Only two of nine cases were solid, the remaining seven were thymic cysts. A preoperative diagnosis is seldom considered and is often misdiagnosed as a possible malignancy or a lymph node. We present a case of a 2-month-old infant with an asymptomatic enlarging right neck mass. Patient underwent complete excision of the mass.     

Giant dermoid cyst of the neck can mimic a cystic hygroma: using MRI to differentiate cystic neck lesions

OBJECTIVE: To describe differential features of giant cervical dermoid cysts and other cystic lesions of the head and neck. METHODS: Case report including magnetic resonance imaging, surgical excision, pathologic examination and correlation. RESULTS: We report the case of a 15-year-old boy who presented for evaluation of a slowly enlarging doughy submental mass. Ultrasound showed some features consistent with a cystic hygroma and both sclerotherapy and surgical excision were discussed with the family. However, an unusual solid component on magnetic resonance imaging (MRI) mitigated toward surgical excision. At surgery, the cystic mass was excised and measured 9.5 cm x 5.5 cm x 4.0cm. Histology showed a giant dermoid cyst similar to those seen in the ovary. The solid component was a smooth spherical collection of inspissated sebum. CONCLUSIONS: The unique MRI characteristics of giant dermoid cysts can help to separate these rare lesions from more common cystic hygromas. Fine needle aspiration should be considered for questionable lesions before treatment with OK 432 or similar agents.     

Mature teratoma of the nasal vestibule: a case report

Teratomas are rare congenital neoplasms that arise from pluripotent cells. They consist of tissue from all three embryonic germ layers. According to most studies, teratomas of the head and neck account for only 2 to 9% of all cases. In this article, we report the first case of a teratoma of the nasal vestibule in a newborn. We also discuss methods of diagnosis and treatment of upper airway teratomas, and we include a brief review of the literature.     

Malignant cervical teratoma: report of a case in a newborn

Malignant cervical teratoma (MCT) usually appears in newborns as an enlarging mass of the neck that causes respiratory distress, requiring prompt airway control. We report a case of MCT in an infant electively delivered at 32 weeks to prevent airway impairment. At first, the preoperative diagnosis was hygroma of the neck, and a surgical excision was performed when the newborn was 9 days old. Diagnosis was benign extragonadic immature teratoma, but it was changed in MCT when cervical metastases appeared and the alpha-fetoprotein (AFP) level increased. Subsequent surgical procedures and chemotherapy were necessary. The child has been free from disease and healthy for 7 years since the last surgery. The preoperative diagnosis of MCT is difficult because of its rarity and non-specific clinical findings. Surgical excision is required for an adequate cure and airway repair; a long-term follow-up is mandatory to promptly treat any recurrence.     

Congenital laryngeal saccular cyst: report of a case in an infant

Respiratory obstruction and stridor in infants and children are not uncommon. A rare cause of these life-threatening symptoms is congenital saccular cyst. An accurate diagnosis of saccular cyst can be made by eliciting a good history, by endoscopic visualization of the lesion, and by computed tomography. Endoscopic excision is the preferred treatment for infants, whereas an external approach is reserved for older children. It can be difficult for anesthetists to intubate infants when the anatomy of the larynx is distorted, but the choice of tracheotomy for an infant has many drawbacks as well. We discuss the clinical presentation and management of a 3-month-old boy who was brought to us with a congenital laryngeal saccular cyst.
