CONTEXT Pancreatic cystic lesions are increasingly recognized and comprise different pathological entities. The management of these lesions is challenging, because of inadequate preoperative histological diagnosis. Among this family of lesions, mature cystic teratomas are an extremely rare finding. CASE REPORT We present the case of a 61-year-old man with a mature cystic teratoma of the pancr...

Cystic lymphangioma of the colon (CLC) is a rare benign lesion that is usually asymptomatic and found incidentally during colonoscopy. Limitations in the conventional noninvasive diagnostic techniques have led to surgical resection of these lesions for diagnostic confirmation. Classic endoscopic ultrasound (EUS) findings of colonic cystic lymphangioma are submucosal anechoic cystic spaces with ...

Abdominal echo revealed biliary tracts dilatation; ERCP revealed amorphous filling defect inside the dilated CBD, a cystic tumor in the left lobe communicated with bile duct was disclosed by MRI/MRCP. He received left lobectomy and microscopic findings proved h...

Decompression is considered an effective treatment for odontogenic cystic lesions in the jaw. A variety of decompression devices are successfully used for the treatment of keratocystic odontogenic tumors, radicular cysts, dentigerous cysts, and ameloblastoma. The purpose of these devices is to keep an opening between the cystic lesion and the oral environment during treatment. The aim of this r...

A 4-year-old Japanese boy presented with cystic lesions on the ventral midline of the penis from birth.
