Osteosarcomas are highly malignant neoplasms of bone that are challenging to diagnose. These neoplasms often show atypical behavior. In the initial phase they may present as nondescript bony swellings with an indolent growth rate, only to become overtly aggressive and malignant towards the later phase of the disease. Similarly, the histological growth pattern of this neoplasm can be quite diver...

Abstract The growth pattern of the Polish phytosaur Parasuchus cf. arenaceus and aetosaur Stagonolepis olenkae (both Krasiejów; Norian) was studied. Results were compared to published data other members these two groups a new sample German (Heslach; Nicrosaurus sp. All three herein studied taxa display lamellar-zonal bone consisting predominately parallel-fibred tissue on average low moderate v...

Adamantinoma of the long bones is a low-grade, slow-growing, primary malignant bone tumor composed of epithelial cells in a fi brous or osteofi brous stroma.1,2 It has a wide range of histological patterns.3-18 Despite the considerable range of each histologic pattern, most current studies have shown that long bone adamantinoma appears to be of an epithelial nature. The tibial lesion’s name com...

Malignant pleural mesothelioma (MPM) is an increasingly prevalent tumour. The death rate associated with MPM is predicted to peak in the next 10 years, although radiologists and clinicians will be encountering cases for the next few decades. Contrast-enhanced CT is an established technique for evaluating suspected malignant pleural disease, but MPM can be reliably diagnosed only by histological...

Background: Focal segmental glomerulosclerosis (FSGS) is a pattern of injury and it has five histological subtypes with varying prognosis therapeutic response. Our aim was to study the primary FSGS in our population along their clinicopathological characteristics.Methods: This 2-year retrospective, single centre cohort, observational study. All adult patients were identified.Results: There 51 F...
