RESUMO

Congenital cystic adenomatoid malformations of the fetal lung (CCAM) are rare embryonic developmental abnormalities. They are considered as benign hamartomatous or dysplastic lung tumors characterized by overgrowth of the terminal respiratory bronchioles at the expense of the saccular spaces. A minority of cases may not be identified by prenatal imaging techniques and the pulmonary lesions are recognized postnatally. Two cases of congenital cystic adenomatoid malformation of the fetal lung diagnosed in our institution during the last four years are reported. The ultrasonographic and pathologic findings of these cases are discussed.

RESUMO

Paraganglioma of the urinary bladder is a rare pathologic entity with no definitive histological, immunohistochemical or molecular features to determine its malignant potency. Malignancy is essentially determined by the presence of deep local invasion, invasion of adjacent structures, and lymph node or distant metastases. So far, up to 180 cases of paraganglioma have been reported, with less than 30 being malignant. We present a case of malignant paraganglioma of the urinary bladder in a 44-year-old woman. The patient's symptoms were painless hematuria and micturitional headache. The tumor presented the characteristic "zellballen" pattern of growth and immunohistochemically was positive for all neuroendocrine markers. The patient underwent partial cystectomy and the following two postoperative years were uneventful. The literature on paraganglioma of the urinary bladder, analyzing the histological, immunohistochemical and molecular characteristics, is reviewed.

RESUMO

AIM: To present the classification and diagnostic problems encountered between teratomas and other ovarian tumors as well as with other benign entities diagnosed and treated in our institution. METHODS: We analysed retrospectively the clinical and pathological characteristics of 87 teratomas examined in our hospital during the last ten years. RESULTS: Teratomas constituted 5% of all ovarian tumors. The age range was from 11-69 years old (median: 35). The most frequent symptom was lower abdominal pain in 68% of patients. A pelvic mass was noted in 3% of cases. A pregnancy was present in 3% of patients. In ten cases the tumors were bilateral. Tumor size ranged from 1-16 cm in diameter (median: 7.17 cm). The treatment consisted of cystectomy in 66% of the cases, oophorectomy in 23% or hysterectomy with both adnexa in 11% of cases. Fifty-seven cases presented with a histological diagnosis of mature teratoma, biphasic or triphasic type, three cases with monodermal teratoma, ten cases with ovarian neoplasms of mixed type, 15 cases with epidermal cysts, and two cases with benign cysts. Malignant changes within the teratomas were seen in 5% cases. CONCLUSION: Teratomas are common ovarian tumors at any age, especially during the reproductive age, with a low rate of complications and malignant transformation. The treatment should be based on patient age, fertility status, tumor size, the cystic or solid nature of the tumor and bilaterality.
