The macrocystic variant of serous cystadenomas of the pancreas has only recently been described. We present a case of a 40 year-old female, who presented with vague indigestion. The cyst was unilocular, and was lined by simple cuboidal, ciliated serous type epithelium. Fine needle aspiration, immunohistochemical, light microscopic, and electron microscopic studies are discussed.

A 36 year old man developed slowly progressive unilateral visual loss due to a cystic lesion of the intraorbital optic nerve. Pathologically the lesion was an epithelium lined cyst entirely within the atrophic nerve. The cyst lining consisted of columnar epithelium partly pseudostratified and ciliated with evidence of mucin secretion, and was immunoactive for cytokeratin but not glial fibrillar...

Duplication cyst of the stomach is a rare congenital malformation, typically diagnosed in the first year of life. In most adult cases the cyst remains asymptomatic, but patients may present with abdominal symptoms including epigastric discomfort or pain. We present a case of a 65-year-old male with an asymptomatic gastric tumor diagnosed incidentally during initial workup of his esophageal aden...

A 33-year-old man had dizziness for 3 days without provoking factors. Head CT demonstrated a mass in the left lateral anterior cranial fossa with calcification and cystic degeneration (figure 1, A–C). MRI showed an irregularly shaped mass with mixed signal and slight marginal enhancement (figure 1, D–F). He underwent mass resection with no recurrent dizziness during 12 months’ follow-up. On pat...

Gastric duplication cysts (GDC) lined with pseudostratified columnar ciliated epithelium (PCCE) are uncommon lesions that stem from a foregut developmental malformation. The clinical and radiological diagnosis is usually difficult. Definitive diagnosis can be established by histopathological examination. In this study, we report a rare case of a peri-gastric mass that was operated and reported ...

Bronchogenic cysts are congenital foregut malformations thought to develop due to abnormal budding of tracheal diverticulumand proximal bronchial structures during embryologic development. The cyst is lined by ciliated pseudostratified columnar epithelium and the wall contains cartilage and layers of smooth muscle. These lesions most commonly are seen in the mediastinum, lung, or pleural spaces...

A mediastinal Mullerian cyst was initially reported as a new category of congenital cyst by Hattori, et al. in 2005. We treated a 53-year-old female referred to us with a posterior mediastinal tumor found at the Th5 prevertebral level by chest-computed tomography during a medical check-up. She had a history of mediastinal teratoma, which was removed at the age of 35. Chest magnetic resonance im...
