Thyroid glands from 160 patients, aged 11 to 95 years, without known thyroid disease, collected from medicolegal autopsies, were sectioned at 3-5 mm slices and microscopically examined for occult disease. The glands were normal in 57.9%, while nodules were observed in 16.8% and adenomas in 10.6% of the cases. Carcinomas were found in 12 cases (7.7%) and(More)
A case of intrauterine fetal death with rupture of a hemangioma in the umbilical cord is presented. Hemangiomas are uncommon tumors of the umbilical cord, and their clinical significance is not entirely clear, but associations with polyhydramnios, fetal disseminated intravascular coagulation, and fetal hydrops have been described. In a high proportion of(More)
The diagnosis of papillary carcinoma of the thyroid is based on the two morphological features that best characterize this tumor, the papillae and the nuclear changes. However, both the architectural and cytological hallmarks may be encountered in other conditions such as multinodular goiter, Grave's disease, thyroiditis and hyperplastic areas of follicular(More)
Purpose: To compare the damage caused by vibrating guidewire manipulation and conventional guidewire manipulation of soft coronary wires in normal sheep coronary arteries. Methods: Using an intact sheep model the two methods of passing a coronary guidewire down a normal coronary artery under fluoroscopic screening control were studied. The resulting(More)
AIM To compare the expression of anti-apoptotic protein bcl-2 and tissue proliferation Ki-67 antigen in tissues of human papillary thyroid carcinoma (PTC) and papillary thyroid microcarcinoma (PTMC). METHODS Bcl-2 protein expression in PTC and PTMC has been evaluated by immunohistochemical analysis. RESULTS Bcl-2 protein was observed in normal thyroid(More)
Cysts that involve the esophagus, account for 10 to 15% of all primary masses of the mediastinum and, although rare, are probably the second most common benign esophageal tumor, with leiomyoma being by far the most usual [1, 2]. Esophageal cysts are classified according to their embryological site of origin, into inclusion cysts (lined by squamous or(More)
Giant hemangioma of infancy is a rare and extensive variant of the hemangiomas, that occurs in newborns and infants and is often complicated by life-threatening events. We describe herein an unusual case of a giant hemangioma in a female infant. At the age of 45 days she was admitted to the hospital because of increasing respiratory distress and distented(More)
INTRODUCTION Male breast cancer is rare compared to its female counterpart representing less than 1% of cancer in men. Moreover, mucinous carcinoma of the male breast is an extremely rare histological subtype of malignancy. Paget's disease of the nipple is rarely observed in males. CASE REPORT Herein, we describe a unique case of an 86 years old man with(More)
Dermatofibrosarcoma protuberans (DFSP) usually occurs in adults, however it can also occur in infancy and childhood. Diagnosis of DFSP in children is quite difficult given the rarity of the tumor and its variegated appearance. The behavior of this neoplasm is of borderline or intermediate malignancy with a high rate of recurrence but limited metastatic(More)
