pediatric mediastinal tumors and include thymic cysts, hyperplasia, carcinoma, thymoma and thymolipoma (1). Thymomas are rare tumors of the thymic epithelium with a broad spectrum of morphological and clinical features; they comprise about 1% of mediastinal tumors. Familial occurrence of these tumors has been rarely reported (2-4). We report an unusual familial occurrence of three cases of thym...

Most contain a clear jelly like fluid. These cysts are extramural and share the common muscular wall of the oesophagus [2]. The oesophageal duplication cysts are commonly asymptomatic. If gastric mucosa persists it...

Paraesophageal bronchogenic cyst was one of common mediastinal congenital cystic lesions of foregut origin. Because of an intimate embryologic relationship with the esophagus, they were usually found intramural (intramural esophageal bronchogenic cysts) with the local esophageal mucosa being intact and the paraesophageal bronchogenic cysts were rarely communicated with esophageal lumen. We repo...

are usually expressed in the form of a cystic mass in the neck. Anomalies of the second branchial cleft account for approximately 95% of all branchial cleft cyst (1). Congenital abnormalities of the branchial apparatus can result in various abnormal conditions of the neck including cyst, sinus, or fistulae. The number of cysts is more common than sinuses and fistulae combined. Moreover the anom...

Most mediastinal tumours and cysts follow a definite pattern due to their site of origin and the effect upon neighbouring structures of their enlargement. A small number deviate from the usual picture, and it was felt that the examination of a large series might disclose enough of these variants to enable some contribution to be made to the basic aetiology and diagnosis of these tumours. The pr...

Duplication cysts of the mediastinum are not common. Morrison (1958) includes six in a series of 332 mediastinal cysts and tumours; in his Table 1 (which includes his own series) 15 gastric and enterogenous cysts were found in a total of 1,055 published cases of mediastinal cysts and tumours, an incidence of 1 5 %. Although cases have been described (Mixter and Clifford, 1929; Gross, Neuhauser ...

Esophageal duplication cyst is a rare congenital anomaly. They can be associated with other congenital anomalies, such as spinal abnormalities, and tracheoesophageal fistulas. In adults, almost of the patients with esophageal duplication cyst is asymptomatic and accidentally diagnosed by chest X-ray or computed tomography. However, cysts may become symptomatic owing to complications such as eso...
