BACKGROUND Few studies regarding oral lesions of children and adolescents were reported in the medical literature. The aim of this study was to determine the frequency of these lesions in patients from birth to 20 years old in Babol, Northern Iran. METHODS The slides of all cases of oral lesions in children and adolescents, between 1990 and 2012 were obtained from the pathology archives of Sh...

INTRODUCTION Pancreatic cysts are now being encountered by primary and specialty care physicians with ever increasing frequency due to the widespread use of high quality cross-sectional imaging (1,2). The majority of these cystic lesions are incidental asymptomatic findings, and therefore can present both diagnostic and therapeutic dilemmas. The differential diagnosis of cystic pancreatic lesio...

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. Examination of his genitalia revealed multilobulated, freely mobile, cystic papules, 2 ± 4 mm in diameter, on the ventral surface of the penis from the frenulum to the anus. These cysts were translucent and brown ± black in color (Fig. 1). One large cystic lesion was surgically removed for hi...

Calcifying cystic odontogenic tumor is an uncommon odontogenic neoplasm which is included in the heterogenous group of lesions under a broader description of Ghost cell odontogenic tumors. All these lesions have the presence of ghost cells as a common feature. Calcifying cystic odontogenic tumor is a unique lesion with variable biologic behaviour and found to occur with other odontogenic tumour...

Mediastinal lymphangioma is primarily a benign lesion and the majority of the cases are found incidentally. These lesions account for approximately 1% of all mediastinal tumors. Here we present a giant mediastinal cystic mass in a 35-year-old female who was presented with severe respiratory distress. On the plain chest radiography and CT scan, a massive left pleural effusion with large paraster...

Post-traumatic osseous cystic lesions are a rare complication in children. An aetiology of intramedullary fat seepage through the damaged bone cortex and its entrapment within the subperiosteum has been proposed. These lesions run a benign course and usually resolve spontaneously. The presence of fatty marrow gives it a distinct appearance which aids in its diagnosis and differentiation from ot...

Context Mucinous cystic neoplasms are cystic lesions of the pancreas with a relevant risk to progress to invasive cancer. Mucinous cystic neoplasms are characterized by the presence of an ovarian-like stroma and its almost exclusive occurrence in women. Case report Here we report the case of a 41-year old patient with a known cystic lesion that became symptomatic briefly after pregnancy. A panc...

the nodular thyroid diseas is one of the most common disturbances o the thyroid gland wheras malignant tumors are among the most unusual entities of it. not only differentiation of these two spectra but also the problems to achieve early diagnosis and treatment, have been a matter of concern, research, and controversy. two hundred patients were assessed at the cancer institute of imam khomeini ...

OBJECTIVES The majority of the pathologic structures which are seen in the oral and maxillofacial region are either cystic or tend to show cystic changes. They may have not specific clinical and radiographic findings. Therefore, it is difficult to differentiate these lesions preoperatively. For this purpose, in this research, the value of fine-needle aspiration cytology (FNAC) in preoperative d...
