False aneurysm or pseudoaneurysm is usually a result of blunt trauma causing laceration of part of the vessel wall and extravasation of blood into surrounding tissue, followed by tamponade and clot formation. The wall of the pseudoaneurysm consists of perivascular fibrous tissue. Extracranial carotid artery pseudoaneurysms are relatively rare because trauma(More)
Melanotic neuroectodermal tumour of infancy (MNTI) is an uncommon tumour affecting predominantly the craniofacial bones of the newborn infants. The neural crest origin of the tumour has been confirmed. MNTI is generally accepted as a benign tumour despite of its rapid and locally infiltrative growth. Recurrence rate varies between 10% and 60%, and malignant(More)
INTRODUCTION The aim of this study was to determine the types, frequency, distribution, and demographic characteristics of salivary gland tumours in a large representative sample. PATIENTS AND METHODS We retrospectively analysed the medical records of 779 patients with tumours of the salivary glands surgically treated from 1985 to 2009 at a single(More)
Constitutional hemizygous inactivation of PTCH, the Shh signaling pathway gene that moderates the signal, manifests itself as nevoid basal cell carcinoma syndrome or Gorlin syndrome, a condition variably characterized by a number of developmental disorders and malformations, and by predisposition to some malignancies, basal cell carcinoma in particular.(More)
Primary tracheal tumors are extremely rare, and the majority of them are malignant. Inflammatory pseudotumor is a benign, tumorlike lesion, most likely of a reactive nature. Its basic morphologic characteristic is spindle cell (myoblasts and fibroblasts) proliferation with a variable number and type of inflammatory cells. A case of intratracheal(More)
Glandular odontogenic cyst (GOC), an unusual multilocular cystic lesion of jaws exhibiting the features of both botryoid odontogenic cyst and mucoepidermoid tumor has been reported recently as a new entity with uncertain histogenesis. The World Health Organization named GOC as an independent pathologic entity and classified it as a developmental odontogenic(More)
The authors present two cases of calcifying odontogenic cysts, which were confirmed by histological examination. In the first case the radiographic findings and clinical status did not indicate the presence of a calcifying odontogenic cyst. In the second case, differential diagnosis included COC. The histopathological findings showed that what appeared to(More)
Mucoepidermoid carcinoma of the larynx is very rare, with only a few individual cases or studies in small patient groups reported in the literature. Treatment modalities for this type of carcinoma are not uniform; in addition, errors in the recognition and pathologic diagnosis are not uncommon. During the period 1991-2000, 771 cases of malignant laryngeal(More)
The dilated odontome is the most severe form of the dens invaginatus (dens in dente), which is extremely rare in the mandible, especially in the molar region. A case is reported in a 28-year-old female with an unusual ringlike radiopaque appearance of the mandibular third right molar on panoramic x-ray. CT scan findings were suggestive that the intraosseous(More)
The aim of the study was to compare morphometric characteristics of different types and grades of breast cancer. Morphometric analysis was performed using the SFORM software (Vamstec, Zagreb) on the May-Grünwald-Giemsa stained fine needle aspiration cytology (FNAC) breast tissue specimens. The study included 42 patients diagnosed with breast carcinoma by(More)
