Granular cell tumor is an infrequent, predominantly benign tumor originating from Schwann cells. Granular cell tumor of the breast (GCTB) can simulate breast malignant carcinoma on the clinical assessment. We herein present a rare case of GCTB which recurred in the contralateral breast. We believe the contrast-enhanced ultrasound (CEUS) findings of GCTB have never been described. The high similarity of breast malignant carcinoma makes its differential diagnosis difficult on the clinical and radiological features. In this report, we present the CEUS findings from a rare case of GCTB, explore the possible value of CEUS in differential diagnosis between benign breast lesions and malignant ones, and briefly review the literature.

Introduction:The aim of the current study was to evaluate the association of spironolactone and arterial stiffness and composite cardiovascular disease (CVD, including coronary heart disease, congestive heart failure and ischemic stroke) in hypertensive patients.Material and methods:Baseline data were collected and arterial stiffness was presented by carotid-femoral pulse wave velocity (cf-PWV) using applanation tonometry. Serum levels of fasting plasma glucose, total cholesterol, C-reactive protein and creatinine were measured using an automatic biochemistry analyzer. Plasma aldosterone concentration and plasma renin activity were determined by radioimmunoassay. The associations of spironolactone and arterial stiffness and composite CVD were evaluated.Results:Compared to patients without spironolactone (n = 274), those with spironolactone (n = 170) were older and more likely to have diabetes and chronic heart failure. No differences in antihypertensive medications used were observed except for spironolactone. Mean number of antihypertensive medications used was significantly higher in the spironolactone group (2.6 ±0.8 vs. 2.2 ±0.6). Compared to patients without spironolactone, those with spironolactone had significantly lower cf-PWV (9.4 ±1.8 vs. 10.1 ±2.2 m/s). After adjustment for covariates, spironolactone was still associated with 10% lower risk of arterial stiffness, with a 95% confidence interval (CI) of 0.85-0.97. In patients without arterial stiffness, after adjustment for covariates, no significant association of spironolactone and composite CVD was observed. However, in patients with increased arterial stiffness, after adjustment for covariates, spironolactone was still independently associated with 11% lower risk of composite CVD (95% CI: 0.83-0.97).Conclusions:Spironolactone treatment is independently associated with lower cf-PWV and lower prevalence of composite CVD in patients with increased arterial stiffness.

INTRODUCTION:The current study aimed to evaluate the association of anti-hyperuricemia treatment and prevalent cardiovascular disease (CVD) in hypertensive patients.MATERIAL AND METHODS:Primary hypertensive patients with hyperuricemia were enrolled. All participants were separated into two groups: anti-hyperuricemia and control groups (without anti-hyperuricemia treatment). Comparisons of prevalent CVD including coronary heart disease, ischemic stroke and heart failure were made and the associations of anti-hyperuricemia treatment and prevalent CVD were analyzed.RESULTS:Compared to the anti-hyperuricemia group, patients in the control group had significantly higher serum C-reactive protein (10.6 ±2.8 vs. 7.4 ±1.2 mg/dl) and uric acid (UA) levels (438 ±33 vs. 379 ±64 µmol/l), and were more likely to receive β-blockers (34.2% vs. 31.1%) and calcium channel blockers (49.2% vs. 43.4%). The prevalence of ischemic stroke was higher in the control group (15.8% vs. 11.3%). Compared to other groups, blood pressure was significantly higher in patients in the 4th quartile serum UA level group. In the unadjusted model, anti-hyperuricemia treatment was significantly associated with a reduced odds ratio (OR) of composite CVD. After adjusting for potential covariates, OR of anti-hyperuricemia treatment for composite CVD was 0.89 with a 95% confidence interval (IC) of 0.82-0.98. Associations of anti-hyperuricemia treatment and ischemic stroke were also significant with OR = 0.93 and 95% CI: 0.88-0.99, while associations of anti-hyperuricemia with coronary heart disease and heart failure attenuated into insignificance after adjusting for covariates.CONCLUSIONS:In hypertensive patients with hyperuricemia, anti-hyperuricemia treatment was associated with lower odds of prevalent CVD.
