Amongst the various cystic lesions of oral cavity, Lymphoepithelial cyst (LEC) is a rare lesion that presents as an asymptomatic submucosal mass and usually discovered during routine examinations. Most common site occurence floor mouth but tonsillar involvement seems to be very rare. Pathogenesis involves excessive accumulation desquamated epithelial lining in crypt. This results dilated obstru...

OBJECTIVES We report two cases of infants found to have congenital omental cystic lesion with torsion and ovarian cyst treated by laparoscopy-assisted surgery (LAS). METHODS A laparoscope was inserted by an open method. The intra-abdominal pressure was maintained at 8 mm Hg. We diagnosed the cystic lesions with torsion. At aspirator was used to aspirate the cystic content and remove the cyst....

Retroperitoneal cystic lymphangiomas are rare tumors of the lymphatic system. These tumors usually present in childhood and are often diagnosed incidentally with imaging procedures. Although benign, they can grow to large sizes and become symptomatic due to their compressive effects. They can cause diagnostic dilemmas with other retroperitoneal cystic tumors including those arising from the liv...

Teratomas are characterized by containing tissue from all three germinal cell layers. Occasionally, somatic type malignancies develop within a mature cystic teratoma. We reported here a rare case of enteric type adenocarcinoma, with associated dysplastic epithelial precursor lesion, arising within a mature cystic teratoma in the retroperitoneum of a 30-year-old woman status post vaginal deliver...

Desmoid tumors, also called deep or aggressive fibromatosis, are uncommon mesenchymal tumors characterized by proliferation of fibroblasts in an abundant collagen extracellular matrix. They rarely involve the pancreas, and the diagnosis is difficult to make if they do. Only eleven cases have previously been reported involving the pancreas in a review of the literature. In these reported cases, ...

We report two cases of cystic neoplasm of the liver with mucinous epithelium in which both ovarian-like stroma and bile duct communication were absent. The first case was a 41-year-old woman. She underwent right trisegmentectomy due to a multilocular cystic lesion, 15 cm in diameter, with papillary nodular components in the medial segment and right lobe. Histologically, arborizing papillae were...

Subcutaneous bronchogenic cysts have been described rarely, particularly among adolescents. Only a few reports have described the ultrasonographic features of bronchogenic cysts, characterizing them as nonspecific cystic masses with or without internal echogenic foci or debris. Therefore, it is hard to differentiate subcutaneous bronchogenic cysts from other subcutaneous cystic tumors ultrasono...

BACKGROUND Cavernous malformations (CMs) in the cerebellopontine angle (CPA) are rare, and most of such CMs reported to date are solid and extend from the internal auditory canal into the CPA. In contrast, cystic CMs that arise in the CPA and do not involve the internal auditory canal and dura of the skull base are extremely rare. CASE PRESENTATION A 50-year-old man presented with vertigo and...
