Breast hamartoma is an uncommon breast tumor that accounts for approximately 4.8% of all benign breast masses. The pathogenesis is still poorly understood and breast hamartoma is not a well-known disorder, so its diagnosis is underestimated by clinicians and pathologists. This study was designed to present our experience with breast hamartoma, along with a literature review. We reviewed the demographic data, pathologic analyses and imaging and results of patients diagnosed with breast hamartoma between December 2003 and September 2013. In total, 27 cases of breast hamartoma operated in the Ankara University Medicine Faculty's Department of General Surgery were included in the study. All patients were female and the mean age was 41.8±10.8 years. The mean tumor size was 3.9±2.7 cm. Breast ultrasound was performed on all patients before surgery. The most common additional lesion was epithelial hyperplasia (22.2%). Furthermore, lobular carcinoma in situ was identified in one case and invasive ductal carcinoma was observed in another case. Immunohistochemical staining revealed myoid hamartoma in one case (3.7%). Breast hamartomas are rare benign lesions that may be underdiagnosed because of the categorization of hamartomas as fibroadenomas by pathologists. Pathologic examinations can show variability from one case to another. Thus, the true incidence may be higher than the literature indicates.

BACKGROUND: Hysterectomy might adversely affect pelvic floor functions and result in many different symptoms, such as urinary and anal incontinence, obstructed defecation, and constipation. OBJECTIVE: The aim of this prospective study was to evaluate the influence of hysterectomy on pelvic floor disorders. DESIGN: This was a prospective and longitudinal study. SETTINGS: The study was conducted at the Ankara University Department of Surgery and the Dr Zekai Tahir Burak Women’s Health Research and Education Hospital between September 2008 and March 2011. PATIENTS: The study was performed on patients who underwent hysterectomy for benign pathologies. MAIN OUTCOME MEASURES: A questionnaire about urinary incontinence (International Continence Society scoring), anal incontinence, constipation, and obstructed defecation (Rome criteria and constipation severity score), along with an extensive obstetric history, was administered preoperatively and postoperatively annually for 4 years. RESULTS: Patients (N = 327) who had completed each of the 4 annual postoperative follow-ups were included in this study. Compared with the preoperative observations, the occurrence of each symptom was significantly increased at each of the follow-up years (p < 0.001). Over the 4 postoperative years, the frequencies for constipation (n = 245) were 7.8%, 8.2%, 8.6%, and 5.3%; those for obstructed defecation (n = 269) were 4.5%, 5.2%, 4.1%, and 3.0%; those for anal incontinence (n = 252) were 4.8%, 6.3%, 6.0%, and 5.2%, and those for urinary incontinence (n = 99) were 12.1%, 12.1%, 11.1%, and 13.1%. In addition, patients who had no preoperative symptom (n = 70) from any of the selected symptoms showed a postoperative occurrence of at least 1 of these symptoms of 15.8%, 14.3%, 11.4%, and 8.6% for the postoperative years 1, 2, 3, and 4. LIMITATIONS: Although the study had several limitations, no comparison with a control population was the most important one. CONCLUSIONS: Hysterectomy for benign gynecologic pathologies had a significant negative impact on pelvic floor functions in patients who had no previous symptoms.

Renal angiomyolipoma (AML) is a rare benign tumor of the kidney. Occasionally, it may extend into the renal vein or the inferior vena cava (IVC), but so far of pulmonary embolism in patients with renal AML was rarely reported. Here, a case of symptomatic pulmonary embolism secondary to AML that was placed IVC filter before the operation and then treated with radical nephrectomy is reported.This case highlights the rare possibility of renal vein and IVC involvement with symptomatic pulmonary fat embolism in renal AML, which may potentially result in fatal complications if not appropriately and cautiously managed with surgical intervention.

Adenoid cystic carcinoma (ACC) is an uncommon tumor of the breast, accounting for approximately 0.1% to 1% of all breast cancers. It is characterized by rare lymph node involvement and distant metastasis, and associated with a favorable prognosis with excellent survival, despite its triple-negative status. In the current state of knowledge, results of breast-conserving treatment with postoperative radiotherapy seem to be equivalent to mastectomy alone, with respect to survival for ACC of the breast. Due to its rarity, there is no consensus on optimal treatment for patients with ACC. Otherwise, the role of chemotherapy and hormonal therapy remains controversial. Further clinical studies are required to compare treatment options for ACC. But, a long-term follow-up is very important and mandatory for affected patients, due to the late onset of local relapse and occurrence of distant metastasis. Here, we report the case of a patient who presented with a palpable breast mass in the left breast that turned out to be an ACC of the breast.

Objective: Mastalgia is often ignored by physicians although it is the most common breast-related complaint among women. The effectiveness of exercise therapy for mastalgia is unclear. The aim of this study is to investigate the effects of exercise on mastalgia. Methods: A randomized controlled trial was conducted with twenty women with complaints of mastalgia fulfilling the inclusion and exclusion criteria. Patients were randomly assigned to the control group and to the exercise group. Sports brassiere, refraining from caffeine- and methylxanthine-containing foods, and simple analgesics were recommended for two groups. In the exercise group, an exercise program was conducted three times a week for 6 weeks. Participants in both groups were evaluated for breast pain and using the Short-Form Health Survey (SF-36) questionnaire before and six weeks after study. Serum cytokine levels were also collected and analyzed. Results: No significant differences were detected with respect to age, body mass index, menopausal status, psychiatric condition, and existence of unexplained pain syndromes between the groups. Total breast pain scores were similar in both groups. The sensory component of breast pain questionnaire and visual analogue scale values significantly improved via exercise in only exercise group (p = 0.012 and p = 0.016). There was no significant difference between groups in serum levels of cytokines. SF-36 subscale scores for general health and social functioning significantly improved in the control group and scores for role physical, bodily pain, and social functioning improved in exercise group. Conclusions: Based on our preliminary findings, exercise treatment is beneficial for patients with mastalgia and it can be suggested by clinicians.
