Outcomes of high-risk breast lesions diagnosed using image-guided core needle biopsy: results from a multicenter retrospective study.

PURPOSE: The clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions. METHODS: This retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson's chi-squared test, the Fisher-Freeman-Halton test, and Fisher's exact test were used for the statistical analyses. RESULTS: The overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes. CONCLUSION: ADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision.

Granulomatous Mastitis: A Clinical and Diagnostic Dilemma.

OBJECTIVE: Granulomatous mastitis (GM) is a challenging inflammatory disorder of the breast. In this study we aimed to present the detailed clinical and morphological features of GM cases, diagnostic clues for specific and idiopathic etiologies, the difficulties in evaluating trucut biopsies, and the results of different therapeutic approaches. MATERIAL AND METHOD: We retrospectively analysed the clinical, radiological and morphological features of 114 GM cases diagnosed with fine needle aspiration, and trucut, incisional, and excisional biopsy. RESULTS: The mean age was 35.8. Only eight cases were older than 45 years. Bilateral involvement was observed in 4 (3.5%) cases. The most common clinical symptoms were breast mass/abscesses, tenderness, and skin changes. Microbiological culture was positive in 4 cases for gram-positive bacteria. Only 3 cases showed a positive tuberculin/PCR test for tuberculosis. The major USG finding was a hypoechoic well-defined or ill-defined mass/abscess; MRI finding was heterogeneous non-mass contrast enhancement. Cases diagnosed with cytology (35 cases) did not have breast malignancy either in their history or clinical follow up period. Fine needle aspiration cytology materials revealed epitheloid granulomas mixed with neutrophils, lymphocytes accompanied by giant cells, and suppurative necrosis. Histopathological reevaluation of 65 trucut/incisional/ excisional biopsies revealed granuloma formation in 65 (100%), Langhans type giant cells in 59 (90.7%), microabscess formation in 41 (63%), caseous necrosis in 1 (1.5%), neutrophilic cysts in 30 (46.1%), eosinophilic infiltration in 48 (73.8%), interlobular inflammation in 14 (21.5%), fat necrosis in 5 (7.6%), ductal ectasia in 6 (9.2%), and lactational changes in 4 (6.1%) cases. Granulomas were lobulocentric in 58 cases, foreign body type/fat necrosis-related in 6 case, and periductular in 1 case. Cystic neutrophilic granulomatous mastitis was observed in one case. We also evaluated the histochemical stains of these 65 biopsies. Only one sample was positive for acido-resistant bacilli (ARB) by the EZN method and one sample was positive for gram-positive bacilli by gram stain. CONCLUSION: Small, superficial trucut biopsies may cause difficulties in determining the etiology and differential diagnosis of granulomatous mastitis. For optimal management and timing the appropriate therapy, the ideal biopsy procedure, special stains, and a multidisciplinary team consisting of the surgeon, pathologist, and radiologist are the most important issues.

Morgagni hernia in an adult: atypical presentation and diagnostic difficulties.

Foramen of Morgagni hernias are rare diaphragmatic hernias, usually occurring on the right and located in the anterior mediastinum. Adult patients diagnosed with a foramen of Morgagni hernia are usually asymptomatic and associated with obesity, trauma or other causes of increased intraabdominal pressure. Plain pulmonary roentgenogram, radiological studies of the gastrointestinal system with contrast material, computerized tomography and magnetic resonance imaging studies are helpful in diagnosis. In this article, a 78-year-old female case with a Morgagni hernia incidentally diagnosed on chest X-ray is presented.

Serum insulin like growth factor-1 (IGF-1) and insulin like growth factor binding protein-3 (IGFBP-3) levels in liver cirrhosis.

BACKGROUND/AIMS: Impaired growth hormone-insulin like growth factor system in hepatic cirrhosis leads to cirrhosis-related complications. In this study, we aimed to investigate whether serum levels of insulin like growth factor-1 and insulin like growth factor binding protein-3 are related to the level of hepatic dysfunction, clinical grade, and etiologic factors of the disease in patients with liver cirrhosis. METHODS: Forty-two patients with liver cirrhosis who were diagnosed by means of clinical findings, endoscopy, imaging studies, or histopathology were enrolled in the study. An age- and sex-matched control group was comprised of 37 healthy controls with no signs of liver disease by clinical or laboratory findings. The demographic features (age, sex, height, and weight) and serum levels of liver function tests, urea, creatinine, sodium, potassium, insulin like growth factor-1, and insulin like growth factor binding protein- 3 and hemogram values were recorded for each individual. The patients were grouped according to Child Pugh classification and etiology. RESULTS: Insulin like growth factor-1 and insulin like growth factor binding protein-3 levels were significantly lower in the cirrhotic group in comparison to the control group (p<0.005). A statistically significant decrease in levels of insulin like growth factor-1 and insulin like growth factor binding protein-3 was correlated with the degree of liver dysfunction, namely, lowest decrease in Child Pugh class A and highest decrease in class C. With respect to etiology, insulin like growth factor- 1 levels of alcohol-related liver cirrhosis were significantly lower than those of hepatitis B- related cirrhosis. There was no relation between insulin like growth factor binding protein-3 level and etiology. In the cirrhotic group, insulin like growth factor- 1 level was positively correlated with serum albumin and negatively correlated with serum creatinine and sodium levels and spleen size. Likewise, insulin like growth factor binding protein-3 level was positively correlated with serum albumin. There was a negative correlation between insulin like growth factor binding protein-3 level and serum bilirubin and spleen size. CONCLUSIONS: Insulin like growth factor-1 and insulin like growth factor binding protein-3 levels are related to the level of clinical impairment and were independent of the etiology. They may serve as novel markers of hepatocellular dysfunction.
