Purpose: This study aims to analyze Heart Rate Variability(HRV) in women with fibroadenoma compared with non-fibroadenoma women. Methods: We studied 82 patients visiting Kang-Nam Kyung-Hee Korean Hospital Medical Examination Center from January, 2010 to November, 2011. The subjects were categorized in two groups, fibroadenoma group(n=16) and non-fibroadenoma group (n=66). We investigated the difference of HRV between two groups. Results: The square root of the mean squared difference of successive NNs (RMSSD) in fibroadenoma group is significantly lower than non-fibroadenoma group. LF/HF ratio in fibroadenoma group is significantly higher than non-fibroadenoma group. There was no significant difference in low frequency(LF) and high frequency (HF). However, normalized LF in fibroadenoma group is significantly higher than non-fibroadenoma group. In addition, normalized HF in fibroadenoma group is significantly lower than non-fibroadenoma group. Conclusions: Fibroadenoma group is related to autonomic nerve imbalances that is assumed by psychological problems.

Fibroadenoma are one of the most common benign tumors of the breast in young women. Fibroadenoma may be associated with fibrocystic change, proliferative epithelial changes, and extremely rarely with carcinoma. We report here two cases of malignancy arising from a breast fibroadenoma. The patients were 19 and 51 years old and presented with a lump of recent onset. A 19-year-old female patient was diagnosed with mass excision at another hospital, and re-excision was performed at the hospital. Ultrasonography and cytologic examination revealed fibroadenoma and malignancy in a 51-year-old female patient, who was treated with wide excision. The pathological report of the two cases was revealed as DCIS in a fibroadenoma. Because carcinoma arising within a fibroadenoma is so rare, there are few reports of its characteristics or guidelines for treatment. Careful analysis of the unusual carcinoma arising within a fibroadenoma of the breast led to appropriate diagnosis and treatment of various types of lesions. Herein, we report two cases of DCIS arising within a fibroadenoma of the breast and provide a review of the literature.

Phylloides tumor is very similar to giant fibroadenoma in that they have benign appearance in breast radiologic image. Fibroadenoma has no malignant potential, but phylloides tumor is locally recurrent, invasive and may occasionally metastasize. It thus appears that evaluation of the differential point of the two tumor groups by radiologic study is very important. We retrospectively compared sonographic findings of 6 cases of phylloides tumor with those of 4 cases of fibroadenoma, which proved pathologically in Yeungnam University Hospital from 1984 to 1986. The mean age of the patients were 31.8 years old(from 14 to 41 years old) in phylloides tumor and 28.8 years old (from 17 to 40 years old) in giant fibroadenoma, respectively. The viewpoints of this analysis were size, shape and contour of the masses, internal echo pattern, posterior enhancement, and especially the existence of peripheral cyst or septal band echo. We found that diffenentiation of these two tumors by sonography was difficult. But peripheral cyst was found only in phylloides tumor and septal band echo was found largely in giant fibroadenoma. Although the existence of peripheral cyst or septal band echo in the breast mass was not pathognomonic findings, we suggest that the existence of septal band echo is preferential finding to fibroadenoma, and peripheral cyst is preferential finding to phylloides tumor.

Primary breast lesions diagnosed by fine needle aspiration cytology, confirmed by histologic examination were analyzed by morphometry to evaluate the difference between benign and malignant lesions, and the methods obtaining the sample. four size factors and 5 form factors were evaluated in 22 fibroadenomas and 20 carcinomas by image analyzer(Zeiss Ibas 2000) using the H-E stained slides. Nuclear size was significantly larger in the carcinoma cells than fibroadenoma cells both in the cytology and biopsy specimens, but the form factors were not significantly different. Both fibroadencma and carcinoma cells were significantly larger in cytologic smear than histologic section. The cells in the cytology were more regular and round than those in histology, but not statistically significant. Fibroadenomas having cellular proliferation and atypism exhibited larger size and more irregular nuclei than non-proliferative fibroadenoma, but not statistically significant. Therefore nuclear morphometric analysis can be a helpful method to diagnose the questionable breast lesions and is a method appropriate for use as a quality control procedure in the fine needle aspiration cytology.

Spontaneous infarction of fibroadenoma of the breast is very uncommon and may lead to difficulties in clinical and pathological diagnosis. Most reported cases occured in young women during pregnancy or lactation. This report describes imprint cytologic features of an infarcted fibroadenoma in a 19-year-old young woman without evidence of pregnancy. The smears revealed many individually scattered degenerated or necrotic epithelial or spindle stromai cells and naked nuclei on dirty necrotic background. A few sheets of cohesive uniform epithelial cells and a few fragments of stromal cells were also present. Most of the epithelial cells had pyknotic and hyperchromatic nuclei, however, cellular atypism such as pleomorphism, prominent nucleoli or mitosis were not present. Though the necrotic ductular and glandular outline of this case may bear a superficial resemblance to adenocarcinoma, obvious cytologic atypia or mitosis, even in the necrotic areas were not present.

This study was performed in order to evaluate the accuracy and the usefulness of the fine needle aspiration cytology (FNAC) on the breast lesions, to compare the FNAC findings between fibroadenoma and fibrocystic disease, and to determine the accuracy of cytologic Black's nuclear grading. The subjects in this study were 110 cases of FNAC, later confirmed by biopsy, between January 1988 and December 1991. The results are as follows ; 1 Comparison between the results of the FNAC and the histologic findings revealed that FNAC had a sensitivity of 96.6%, a specificity of 100%, a false negative rate of 3.4% a false positive rate of 0.0%, and an overall diagnostic accuracy of 98.2%. 2 Semi-quantitative evaluation of epithelial celluarity, stroma, and naked nuclei in the smears of aspirate showed high celluarity in 56.7% of the aspirates from fibroadenoma and in 0% of those from fibrocystic disease. Abundant stroma was found in 46.7% of the fibroadenoma and none of fibrocystic disease. Numerous naked nuclei were found in 60% of the fibroadenoma and 4.5% of the fibrocystic disease. The overall diagnostic accuracy was 98% 3. In order to determine the accuracy of Black's nuclear grading of FNAC on breast carcinoma, we retrospectively studied 38 cases of ductal carcinomas diagnosed by FNAC with subsequent histologic confirmation. The concordance rate with histology was 94.7%. These results suggest that FNAC of breast is a diagnostically accurate method, and provide for the preoperative differential diagnosis between fibroadenoma and fibrocystic disease. Our results also suggest that the evaluation of nuclear grading of FNAC can predict clinical outcome and decide the way of management of breast cancer.

Most tumors are believed to overexpress several receptors, and small peptides targeting these receptors were developed for diagnosis and tumor therapy during past decade. Here we report that fibroadenoma can be visualized by bladder cancer specific peptide. A 9-mer bladder cancer specific peptide, which was discovered from the phage display method, was synthesized by peptide synthesizer, and additional tyrosine was conjugated at the N-terminal for radioiodination (Y-BP). Y-BP was radiolabeled with $^{131/124}I$ using Iodogen tube. The rat treated with N-butyl-N-(4-hydroxybutyl)nitrosamine for 8 weeks was allowed to grow until large size tumor was developed under axilla. The tumor model was microPET imaged sequentially using [$^{18}F$]FDG and radioiodinated $^{124}I-Y-BP$. The tumor was excised and examined by immunostaining studies. Radioiodinated $^{124}I-Y-BP$ was purified using fast protein liquid chromatography (FPLC) in > 90% radiochemical purity. The whole tumor was well visualized by [$^{18}F$]FDG with several intense focal uptake within tumor. The tumor was also clearly seen with $^{124}I-Y-BP$ at 4 h post-injection, and to our surprise the tumor uptake of $^{124}I-Y-BP$ lasted up to three days. The tumor was diagnosed histologically as a fibroadenoma derived from mammary gland. In conclusion, the bladder cancer specific peptide showed the good potential as a new radiotracer for the detection of breast fibroadenoma.

Ectopic breast tissue, which results from incomplete regression of the mammary line during embryogenesis, is observed in 0.2%-6% of the population. Carcinoma development in ectopic breast tissue, especially in the abdominal or chest wall, is rare. Here we present the unusual case of a 38-year-old woman with invasive ductal carcinoma in the ectopic breast tissue on the left side of the chest wall and concurrent fibroadenoma in the ectopic breast tissue on the right side. We also describe the US and MR findings of these masses.

Background: Around 200,000 breast disorders are annually diagnosed all over the world. Fibrocystic changes are the most common breast disorder and fibroadenoma is the most prevalent benign breast tumor. The present study aimed to determine the spectrum, type and prevalence of breast masses in women referred to Shiraz University of Medical Sciences between 2004 and 2012. Materials and Methods: A cross-sectional study was conducted on the diagnostic reports data. Results: A total of 640 samples were studied. Most 57.3% of masses were detected in the left breast, 65%, 28.2% and 6.1% of cases presenting with benign, malignant, and inflammatory lesions, respectively. Among all the samples the most prevalent diagnosis (37.7%) was fibroadenoma and fibrocystic lesions (17%). 174 samples (96% of the malignant cases) were invasive. 6.5% of the benign, and 37% of the malignant cases occurred in post menopause women and the differences were statistically significant. Among those with malignant tumors lymph nodes were involved in 25.6% of menopausal women and 44.2% of non-menopausal ones, and the difference was statistically significant. Conclusions: Regular clinical breast examination beside mammographic follow-ups, especially during menopause, should be carried out as a priority and a national organized program should be designed for screening breast disorders.

Adenomyoepithelioma is an uncommon benign tumor of the breast. We present the fine needle aspiration cytologic features of adenomyoepithelioma in a 23 year-old Korean women, initially diagnosed as fibroadenoma. Aspiration cytologic findings of the left breast mass revealed high cellularity, small to medium sized, less cohesive epithelial clusters, rich naked cells and amorphous materials on background. The epithelial cells were round and uniform with no cytologic atypia or mitosis. Myoeplthelial cells were conspicuous with peripheral rimming along the epithelial clusters. Small amount of fibrotic stromal tissues were observed. Distinguishing features from typical fibroadenoma are less tight epithelial clusters, dyscohesive epithelial cell aggregates, more abundant naked cells and scant stromal tissue fragments.
