1. As proposed by Schürmann & MacMahon (1933), we suggest that two types of malignant nephrosclerosis exist. 2. In the type called primary malignant nephrosclerosis, renal vascular lesions precede hypertension. 3. In the second type, called secondary malignant nephrosclerosis, renal vascular lesions are considered to be the consequence of malignant hypertension.

background the most common soft tissue tumors during infancy and childhood are vascular lesions. although the vast majority of these lesions have typical clinical features with no need for any further exam, but sometimes atypical superficial or deeply located lesions require complementary studies to be diagnosed and classified. in that way it is also very important to exclude very less common m...

PURPOSE We aimed to determine the apparent diffusion coefficients (ADCs) of focal breast lesions on diffusion-weighted magnetic resonance imaging (DW-MRI) and to evaluate whether ADC measurement can be used to characterize lesions as benign or malignant. MATERIALS AND METHODS Fifty-one patients between the ages of 18-79 years (mean age, 48.5 years) with 51 histopathologically verified breast ...

BACKGROUND Cancer of the cervix is the most common malignancy in women of childbearing age in Zambia. It is known to be associated with HIV infection and oncogenic strains of HPV. However, there are few studies of penile lesions as a predictor of malignant and premalignant cervical lesions in female partners. OBJECTIVES The aim of the study was to determine the association between men with pe...

desmoplastic fibroma (df) is a rare and locally aggressive intraosseous tumor with unknown etiology. the mandible is the common site of involvement in the maxillofacial region. however, it is believed that df can arise in any bone of the body. a wide age distribution has been reported for df occurrence, extending from birth to the sixth decade of life, with a peak incidence at 10 to 19 years of...

OBJECTIVE The purpose of this study was to present the MRI and CT findings of solitary spinal bone lesions (SSBLs) with the aims of aiding the differential diagnoses of malignant tumors and benign lesions, and proposing a diagnostic strategy for obscure SSBLs. METHODS The authors retrospectively reviewed the imaging findings of 19 patients with an obscure SSBL on MRI at our hospital from Janu...

zosteriform metastasis is a rare clinical distribution from spreading neoplasms of every organ to the skin. tumors most often arise from a n internal o r hematologic malignancy. w e report a 69-year-old man, a known case of malignant melanoma of the left heel. in this case, multiple red-brown metastatic nodules appeared four months after diagnosis. distribution of metastatic lesions resembled a...

In one-hundred-thirty-nine ROIs the following mean ADC values were found when fitting intensities of all bvalues (29 cysts/ 17 benign/ 24 malignant/ 69 healthy; 2.63±0.37, 1.47±0.21, 0.99±0.18, and 1.85±0.20 mm2/s). Significant ADC differences were found for all types by ANOVA (p<.05). Lowest ADC was found for malignant lesions. Malignant and benign tumors were differentiated with 96% sensitivi...
