INTRODUCTION With the improved quality and widespread availability of diagnostic abdominal imaging, incidental intra-abdominal lesions (incidentalomas) are being increasingly identified. Our objective was to characterize the clinical features of asymptomatic patients with incidentally discovered pancreatic lesions and to assess the accuracy of preoperative radiologic diagnosis against the final...

BACKGROUND The objective of this study was to determine whether acute histologic chorioamnionitis is associated with adverse neonatal outcomes in late preterm infants who were born after preterm PROM. METHODOLOGY/PRINCIPAL FINDINGS The relationship between the presence of acute histologic chorioamnionitis and adverse neonatal outcome was examined in patients with preterm PROM who delivered si...

Osteosarcoma is the most common primary tumor of bone, yet its absolute incidence among malignant tumors is low. Within its strict histologic definition, osteosarcoma comprises a family of lesions with considerable diversity in histologic features and grade. Its prognosis is dependent not only on these parameters but also on its anatomic site. It may occur inside the bones (in the intramedullar...

Determination of hormone receptors is of utmost importance in planning therapy in patients with breast cancer. The aim of the study was to assess the expression of estrogen (ER) and progesterone (PR) receptors in ductal invasive breast carcinoma not otherwise specified (NOS) according to patient menopausal state and tumor histopathology. The study included 549 patients treated at University Dep...

primary sarcomas of the kidney are exceptional. among renal sarcomas, leiomyosarcoma is the most common histologic subtype amounting to 50-60% of all cases. the tumor usually arises from either the renal capsule or smooth muscle tissue in the renal pelvic wall. in this paper, we report a patient with leiomyosarcoma of the kidney presented with non-specific abdominal pain and a palpable mass. hi...

stereologic methods are used to abtain quantitative information about 3-dimensional structures from histologic sections. the aim of the present study was using new and unbiased stereologic techniques to investigate changes in volume and number of glomeruli after chronic lead acetate intoxication both quantitatively and in 3-dimensional spaces.lead is one of the heavy metals that has adverse eff...

PURPOSE Mandibular condylar hyperplasia (CH) is a rare entity that causes overdevelopment of the mandible, creating functional and esthetic problems. The aim of this article was to describe demographic and clinical characteristics of CH, analyze histopathologic features and their association with scintigraphic and clinical findings, and evaluate esthetic and functional results after treatment b...

STUDY OBJECTIVE To determine the diagnostic yield of histologic specimens obtained by postmortem transbronchial biopsy (TBB) in patients with acute respiratory failure requiring mechanical ventilation. DESIGN Standard postmortem histologic examination of lung tissue specimens. SETTING An urban university-affiliated hospital. PATIENTS OR PARTICIPANTS Thirty patients with diffuse pulmonary ...

Early phases of polycythemia vera, essential thrombocythemia, and primary myelofibrosis (PMF) can be difficult to distinguish by morphologic studies alone because they share many morphologic characteristics. Histologic criteria according to the 2008 World Health Organization (WHO) classification are part of the myeloproliferative neoplasia (MPN) diagnosis. Our aim was to assess the reproducibil...
