The effect of polycystic ovarian syndrome on fibrocystic breast changes in postmenopausal women.

Background: Fibrocystic breast changes (FCCs) are benign lesions thought to be caused by an increased estrogen-to-progesterone ratio. One of the most common endocrinopathies that increases this ratio is polycystic ovarian syndrome (PCOS). Although nonproliferative FCCs do not increase the risk of breast cancer, they can make mammographic detection of malignancy in postmenopausal women more difficult. The aim of this study was to investigate the effects of PCOS on the development of postmenopausal FCCs. Methods: This retrospective cohort study used the TriNetX research network to identify two cohorts of postmenopausal women (Z78.0) older than 45, without a prior diagnosis of FCCs (N60.1) or hormone replacement therapy (Z79.890). One cohort included a diagnosis of PCOS (E28.2). The cohorts were balanced for age, race, ethnicity, and hormonally relevant comorbidities. The cohorts were then evaluated for the development of FCCs after menopause. Results: Postmenopausal patients with PCOS were 52% more likely to develop FCCs than those without PCOS (2.2% vs. 1.4%, relative risk 1.52, 95% confidence interval 1.05, 2.22, P = 0.03). Conclusion: Postmenopausal women with PCOS have a higher risk of developing FCCs. Further studies are needed to improve the differentiation of benign FCCs from malignant lesions on imaging for postmenopausal women with PCOS who develop FCCs.

Statin Therapy and Pancreatitis: A Multi-Institutional Retrospective Analysis.

INTRODUCTION:  Acute pancreatitis is a serious condition that has numerous etiologies and often requires hospital admission due to its high mortality rates. Statins are used worldwide to reduce the risk of cardiovascular disease. Some studies have shown an association between long-term statin use and acute pancreatitis. However, other studies have shown no effect or even postulated a mild protective effect. Due to conflicting information in the medical literature, the relationship between statins and acute pancreatitis remains unclear. The current study uses the TriNetX global research database to further investigate the impact of statin use on the development of acute pancreatitis over a five-year period. METHODS:  Two cohorts were created using the TriNetX global research database. One group consisted of patients not taking statins, while the other group included patients taking any statins. Patients in both groups were required to be between the ages of 40 and 75 and had normal low-density lipoprotein cholesterol (LDL) (≤200 mg/dl) and triglyceride (≤150 mg/dl) levels. Patients were matched for age, gender, race, and comorbidities. The statin group was then compared to the no-statin group and measured for the outcome of the incidence of acute pancreatitis and the frequency of episodes within the first five years of statin use. Patients who experienced any acute pancreatitis episode before starting statin therapy or before meeting inclusion criteria were excluded from the study. RESULTS:  Patients on statin therapy were significantly more likely to develop acute pancreatitis compared to patients not taking statin therapy (risk ratio 1.332, 95% CI: 1.242-1.429, P<0.0001). However, the statin group had a lower mean number of pancreatitis episodes than the no-statin group (4.6 vs. 5.3, P=0.043). CONCLUSION:  The results from this large global dataset support the previously established idea that prolonged use of statins is associated with an increased risk of pancreatitis. Clinicians should strongly consider statin-induced pancreatitis when other common etiologies have been ruled out.

Rare Primary Malignant Melanoma of the Breast Presenting as a Solitary Breast Mass in a 43-Year-Old Male.

Primary malignant melanoma of the breast (PMMB) is an extremely rare lesion that carries a poor prognosis. Therefore, it is crucial to examine the patient's medical history, clinical presentation, and histopathology considering this diagnosis. The rarity of this lesion has made it difficult to identify classic presentations or specific treatment guidelines. Staining for specific biomarkers can be helpful for diagnosis in the absence of melanin pigment on histology. Additional molecular studies to determine gene status can also be useful for targeted immunotherapy and increased survival time for patients. In this paper, we introduce a rare case of PMMB without skin involvement presenting as a solitary breast mass in a male and explore the radiology, histology, evaluation, and treatment options.

Mucocele-Like Lesion of the Breast.

Mucocele-like lesions (MLLs) of the breast are rare neoplasms characterized by dilated, mucin-filled epithelial ducts or cysts that can rupture and expel their contents into the surrounding stroma. They are frequently associated with atypia, dysplastic change, and, more recently, pre-malignant and malignant conditions like atypical ductal hyperplasia, ductal carcinoma, invasive carcinoma, or mucinous carcinoma. The malignant potential of MLLs is often challenging to determine from the initial histologic evaluation of a core-needle biopsy due to copious mucin and low cellularity. Therefore, at initial presentation, MLLs should be surgically excised and thoroughly evaluated for malignancy. In this paper, we present a rare case of an MLL and explore the radiology, histology, carcinogenic potential, diagnostic evaluation, and suggested management of the condition.

An Interesting Imaging Presentation of a Common Benign Entity: Fibrocystic Changes in a Postmenopausal Patient.

Fibrocystic changes (FCCs) are common, often benign, breast lesions characterized by adenosis, fibrosis, and cyst formation. These changes are believed to be associated with fluctuating hormone levels and are predominantly found in premenopausal women due to higher levels of estrogen. Certain conditions that cause hormonal imbalances, such as polycystic ovarian syndrome, have also been associated with an increased risk of FCCs. FCCs can occur in postmenopausal women on hormonal replacement therapy but are otherwise extremely rare. Although this condition is primarily considered benign, complex cysts presenting in a rare demographic warrant further evaluation beyond screening mammograms to exclude the possibility of malignancy. In this paper, we present the case of new FCCs in a postmenopausal woman and explore the radiology, histology, carcinogenic potential, treatment options, and potential contributing factors of the condition.
