Hyperplasia of mammary glands is a benign breast disease with disordered breast structure. Nowadays, the incidence rate of breast hyperplasia in women is increasing year by year, and the etiology is related to the imbalance of estrogen and progesterone in the body. The symptoms include breast pain, breast nodules, or nipple discharge, which can develop into breast cancer in the context of psychological pressure. Therefore, it is timely and effectively necessary for people to treat the symptoms. At present, traditional Chinese medicine(TCM) often treats breast hyperplasia by oral drug, external application, acupuncture, moxibustion, and massage, while western medicine often uses hormone therapy or surgery. TCM can regulate hormone levels to treat breast hyperplasia. Acupuncture, moxibustion, and other methods can stimulate acupoints to reduce breast lumps. However, since TCM is easy to produce hepatorenal toxicity after long-term use and simple external treatment is slow to take effect, rapid and effective treatment is difficult to be achieved. Although western medicine can inhibit the disease, it is easy to produce toxic and side effects if taken for a long time. In addition, surgery can only remove the focus and the recurrence rate is high. Some studies have found that the combination of oral and external use of TCM compounds has a significant effect, with mild toxic and side effects, few adverse reactions, and a low recurrence rate. Based on the relevant literature in recent years, this article reviewed the combination of oral and external treatment of TCM in the treatment of hyperplasia of mammary glands, discussed the effectiveness, clinical evaluation indexes, and mechanism, and pointed out the existing shortcomings to explore a comprehensive therapy worthy of clinical application.

Caused by endocrine disorder, hyperplasia of mammary glands(HMG) tends to occur in the young with increasing incidence, putting patients at the risk of cancer and threatening the health of women. Therefore, the prevention and treatment of HMG is attracting more and more attention. Amid the modernization of traditional Chinese medicine(TCM), many scholars have found that Chinese patent medicine has unique advantages and huge potential in treatment of endocrine disorder. Particularly, Chinese patent medicine with the function of blood-activating and mass-dissipating, such as Xiaojin Pills and Xiaozheng Pills, has been commonly used in clinical treatment of HMG, which features multiple targets, obvious efficacy, small side effect, and ease of taking and carrying around. Clinical studies have found that the combination of Chinese patent medicine with other medicine can not only improve the efficacy and relieve symptoms such as hyperplasia and pain but also reduce the toxic and side effects of western medicine. Therefore, based on precious pharmacological research and clinical research, this study reviewed the mechanisms of blood-activating mass-dissipating Chinese patent medicine alone and in combination with other medicine, such as regulating levels of in vivo hormones and receptors, promoting apoptosis, inhibiting angiogenesis, improving hemorheology indexes, enhancing immunity, and boosting antioxidant ability. In addition, limitations and problems were summarized. Thereby, this study is expected to lay a theoretical basis for the further study and clinical application of blood-activating mass-dissipating Chinese patent medicine alone or in combination with other medicine against HMG.

Objective: To investigate the histopathological and immunohistochemical characteristics of benign apocrine cystic papillary hyperplasia of the breast with loss of myoepithelial cell layer. Methods: The clinical data, histopathological features and immunohistochemical profile of patients with benign apocrine cystic papillary hyperplasia of breast with loss of myoepithelial cell layer from January 2016 to December 2021 were examined, in which six patients were identified. Results: All six patients were female, aged 36-61 years (median 46 years), who presented with a breast mass; three cases were from the left breast and three cases were from the right breast. Microscopic examination of all cases showed breast hyperplasia with apocrine cysts, accompanied by different degrees of micropapillary and papillary hyperplasia of apocrine cells. One case was associated with lobular carcinoma in situ, and one case was associated with apocrine ductal carcinoma in situ with intraductal dissemination in adenosis. Immunohistochemical staining of CK5/6, p63, SMA, SMMHC, Calponin and CD10 showed complete absence of myoepithelial cell layer surrounding ducts in apocrine cystic papillary hyperplasia. Conclusions: The myoepithelial cells of apocrine cystic papillary hyperplasia of the breast may undergo abnormal changes and may even be completely lost. The diagnosis should be comprehensively considered along with cytomorphological and histological features to avoid overdiagnosis.

Hidradenoma papilliferum is a rare benign cystic tumor that originates from apocrine glands or anogenital mammary glands. Here, we describe 2 cases of hidradenoma papilliferum of the anus. Two female patients aged 39 and 35 presented with perianal masses with hemorrhoids. The patients underwent hemorrhoidectomy and excision of the lesion. Histopathology confirmed the masses as hidradenoma papilliferum. The postoperative course was uneventful for both patients, and there were no recurrences after 18 and 12 months of follow-up, respectively. Proctologists should consider hidradenoma papilliferum in their differential diagnosis of benign anal tumors. Surgical excision is necessary for diagnosis and treatment of hidradenoma papilliferum.

PURPOSE: The activity of mammary stem cells (MaSCs) is essential to mammary growth, differentiation and regeneration in cycles of pregnancy, lactation, and involution. The capability to recruit the mammary gland through the cycles is attributed to stem cells. It was shown that the intraductal (i.duc) injection of pegylated liposomal doxorubicin (PLD) to multiparous FVB/N mice was associated with a significantly reduced outgrowth potential of mammary gland cells. We have explored i.duc PLD's effect on stem cell number and function in mouse mammary gland and aldehyde dehydrogenase (ALDH)'s availability as a mouse MaSC marker.METHODS: The total mammary epithelium was purified from 6 to 8-month-old FVB/N control and i.duc PLD-administered mice treated twice and analyzed by flow cytometry and limiting dilution cleared mammary fat pad transplants.RESULTS: There was no significant difference in the proportions of stem cell-enriched population (CD49(fhigh)CD24(med)) between control and i.duc PLD-treated groups. However, we found a significant reduction in the outgrowth potential of CD49(fhigh)CD24(med) and CD49(fhigh)CD24(med)ALDH(+) cells from i.duc PLD-treated mammary glands. We discovered that adding ALDH to CD49(fhigh)CD24(med) had the possibility of better marker selection for MaSC of mice.CONCLUSION: We present i.duc administration of PLD to reduce MaSC function, but not the number; and ALDH activity may add further selection of MaSCs to CD49f CD24 in mouse mammary glands. Screening of chemotherapeutic drugs or other natural products by this method of stem cell analysis may provide safe i.duc treatment in breast cancer.

Mammary lesions in sows can prevent suckling piglets from consuming colostrum that provides fundamental nutrients and protective immunity. Although mammary gross lesions are frequently found in sows at farms or slaughterhouses, with the exception of mastitis, they have received little research attention. In this study, we investigated mammary lesions observed in South Korean sows between 2015 and 2016. Mammary tissue samples of 82 sows showing gross lesions during meat inspection were histologically classified and immunohistochemical analysis was conducted to assess the expression of estrogen receptor (ER)-α, ER-β, and progesterone receptor (PR) for mammary hyperplastic lesions as well as that of cluster of differentiation (CD) 3, CD79a, interleukin (IL)-1α, IL-1β, IL-6, and IL-8 for mastitis. Furthermore, 20 swab samples were cultured, and the isolated bacteria were identified using polymerase chain reactions for 16S ribosomal RNA genes. The lesions were classified as hyperplasia, mastitis, or hyperplasia with mastitis. Immunohistochemistry results revealed that there was neither expression of ER-α nor of ER-β, but all examined hyperplastic samples expressed PR. In addition, there was a significant correlation between CD3 and IL-1β expressions, as well as between IL-1β and IL-6 expressions. Regarding the identity of the isolated bacteria, Pseudomonas spp. were most frequently detected. The results of this study have revealed the incidence and characteristics of porcine mammary lesions.

Buffalo mastitis is an important economic problem in southern Italy, causing qualitative/quantitative alterations in milk and resulting in economic losses due to the sub-clinical course and chronic evolution. We investigated 50 udders of slaughtered buffaloes and subjected them to effectual microbiological screening to evaluate macro and microscopic mammary gland changes, immune-characterize the cell infiltrates, and compare the degree of tissue inflammation with somatic cell counts. Numerous Gram-positive and Gram-negative bacteria were isolated from all samples, majority of which were environmental mastitis pathogens. Histological features referable to chronic mastitis were observed in 92% udders. Lymphocytes, plasma cells and macrophages were found to evolve into aggregates in 48% udders, which often organized to form tertiary lymphoid structures (TLSs). A predominance of interstitial CD8+ over CD4+ lymphocytes and, in TLSs, scattered CD8+ lymphocytes in the mantle cells and CD79+ lymphocytes in germinal centers, were evidenced. Environmental pathogens are known to persist and cause chronic inflammatory changes in buffaloes, where CD8+ lymphocytes play an important role by controlling the local immune response. Moreover, the TLSs evidenced here for the first time in buffalo mastitis, could play a role in maintaining immune responses against persistent antigens, thereby contributing in determining the chronic course of mastitis.

PURPOSE: Vesicle-associated membrane protein 8 (VAMP8) is a soluble N-ethylmaleimide-sensitive factor receptor protein that participates in autophagy by directly regulating autophagosome membrane fusion and has been reported to be involved in tumor progression. Nevertheless, the expression and prognostic value of VAMP8 in breast cancer (BC) remain unknown. This study aimed to evaluate the clinical significance and biological function of VAMP8 in BC. METHODS: A total of 112 BC samples and 30 normal mammary gland samples were collected. The expression of VAMP8 was assessed in both BC tissues and normal mammary gland tissues via a two-step immunohistochemical detection method. RESULTS: The expression of VAMP8 in BC tissues was significantly higher than that in normal breast tissues. Furthermore, increased VAMP8 expression was significantly correlated with tumor size (p=0.007), lymph node metastasis (p=0.024) and recurrence (p=0.001). Patients with high VAMP8 expression had significantly lower cumulative recurrence-free survival and overall survival (p < 0.001 for both) than patients with low VAMP8 expression. In multivariate logistic regression and Cox regression analyses, lymph node metastasis and VAMP8 expression were independent prognostic factors for BC. CONCLUSION: VAMP8 is significantly upregulated in human BC tissues and can thus be a practical and potentially effective surrogate marker for survival in BC patients.

BACKGROUND: Flap volume is an important factor for obtaining satisfactory symmetry in breast reconstruction with a transverse rectus abdominis myocutaneous (TRAM) free flap. We aimed to develop an easy and simple method to estimate flap volume. METHODS: We performed a preoperative estimation of the TRAM flap volume in five patients with breast cancer who underwent 2-stage breast reconstruction following an immediate tissue expander operation after a simple mastectomy. We measured the height and width of each flap zone using a ruler and measured the tissue thickness by ultrasound. The volume of each zone, approximated as a triangular or square prism, was then calculated. The zone volumes were summed to obtain the total calculated volume of the TRAM flap. We then determined the width of zone II, so that the calculated flap volume was equal to the required flap volume (1.2×1.05×the weight of the resected mastectomy tissue). The TRAM flap was transferred vertically so that zone III was located on the upper side, and zone II was trimmed in the sitting position after vascular anastomosis. We compared the estimated flap width of zone II (=X) with the actual flap width of zone II. RESULTS: X was similar to the actual measured width. Accurate volume replacement with the TRAM flap resulted in good symmetry in all cases. CONCLUSIONS: The volume of a free TRAM flap can be straightforwardly estimated preoperatively using the method presented here, with ultrasound, ruler, and simple calculations, and this technique may help reduced the time required for precise flap tailoring.

Ectopic breast tissue and male breast cancer are both very rare diseases with only a few reports in the literature. Here, we present the first case of ectopic male breast cancer in the perineum. The patient was a 70-year-old man with a palpable mass in the perineum. A wide local excision and inguinal lymph node dissection revealed invasive breast carcinoma of no special type involving the skin and subcutis, and inguinal lymph node metastases. Immunohistochemical staining showed that the tumor cells were strongly positive for estrogen and progesterone receptors and negative for human epidermal growth factor receptor 2. Moreover, no p53 overexpression was observed. Herein, the clinical and pathologic features, as well as a review of ectopic male breast cancer are discussed.
