SETTING Washington University School of Medicine pediatric dermatology clinics. Patients Of 93 patients younger than 18 years with photographically documented, clinically distinctive scalp nevi, 28 (30%) c...

pillow basalts, belonging to late cretaceous yüksekova complex are extensivelly exposed around elazıg in eastern turkey. this unit is a part of southeastern anatolian ophiolite belt and the southern branch of the neotethys. it represents the products of intra- oceanic subduction volcanism and mainly comprises pillow lavas, dykes and associated with sedimentary rocks. pillow lavas and feeder dyk...

Cirrhosis and hepatocellular carcinoma are the prototypic complications of chronic hepatitis C virus infection in the liver. However, hepatitis C virus also affects a variety of other organs that may lead to significant morbidity and mortality. Extrahepatic manifestations of hepatitis C infection include a multitude of disease processes affecting the small vessels, skin, kidneys, salivary gland...

OBJECTIVE To determine features of eyelid lesions most predictive of malignancy, and to design a key to assist general practitioners in the triaging of such lesions. DESIGN Prospective observational study. SETTING Department of Ophthalmology at Queen’s University in Kingston, Ont. PARTICIPANTS A total of 199 consecutive periocular lesions requiring biopsy or excision were included. MAIN...

BACKGROUND In melanoma, morphology-based classification systems have not been able to provide relevant information for selecting treatments for patients whose tumors have metastasized. The recent identification of causative genetic alterations has revealed mutations in signaling pathways that offer targets for therapy. Identifying morphologic surrogates that can identify patients whose tumors e...

Morphologic measurements of the femoral and tibial features of western population have been done in several studies, which provides the fundamental data for the design of total knee arthroplasty prosthesis used globally, including China. However, researches on anatomic and morphologic features of the knee in Chinese populations of both sexes have never been conducted. Our study was aimed at inv...

BACKGROUND/AIMS Brain and bone metastases are common in patients with lung cancer. The development of metastasis is associated with poor survival in lung cancer patients. Although tumor morphologic features on radiographs are routinely assessed for differentiation between benign and malignant lung nodules, they are not used to predict metastasis. We assessed morphologic features of pulmonary ad...

Chronic lymphocytic leukemia (CLL) and hairy cell leukemia (HCL) are two common chronic lymphoproliferative disorders, each having characteristic clinical, morphologic, and immunologic features. Phenotypically, CD5 reactivity in CLL and C D l l c (Leu-M5) reactivity in HCL have characterized these two leukemias among B-cell disorders. In this study, we report 14 cases of a novel chronic lymphop...
