Triple negative breast cancer originating from a cystic lesion

Malignant neoplasm diagnosed after radiological evaluation of a simple breast cyst is rare. This report described the case of a young patient with an initial simple cystic lesion, whom, in 18-month follow-up examinations, showed a change in the imaging pattern of the cyst, and underwent biopsy, where a triple negative carcinoma was identified. In addition, the diagnosis occurred during pregnancy, which makes the present report even rarer.

The ultrasonographic features of fibrocystic breast disease / 中国医师杂志

Objective:To investigate the routine ultrasonographic findings of fibrinous breast disease lesions , and to provide the basis for the differential diagnosis of fibrocystic breast disease lesions and breast cancer.Methods:The two-dimensional ultrasonography , color doppler flow and elastography of 166 lesions in 144 patients with fibrocystic breast disease confirmed by pathology in Peking University Shenzhen Hospital from January 2015 to February 2021 were retrospectively analyzed.Results:The ultrasonographic characteristics of fibrocystic breast disease lesions were as follows: 74.1%(123/166) lesions were hypoechoic, 57.2%(95/166)lesions were irregular, 49.4%(82/166) lesions were incomplete, 90.4%(150/166) lesions were parallel, 25.9%(43/166) lesions showed small cysts, 24.1%(40/166) lesions showed coarse calcification or fine calcification, 65.1%(108/166) lesions showed no change in posterior echo, 90.4%(150/166) blood flow was poor. The elastography score of 98.2%(162/166) lesions was 2-3 points.Conclusions:The ultrasonographic features of fibrocystic breast tumor are hypoechoic, irregular shape, incomplete edge, with fine or coarse calcification, which are easy to be misdiagnosed as breast malignant tumor. However, the former is characterized by parallel growth, small cyst in the interior, no change in posterior echo, lack of blood supply and soft texture, which provide important basis for clinical differential diagnosis.

Family history of breast cancer and risk of benign breast diseases: an integrative literature review

Introduction: Some benign breast diseases (BBD) can determine an increased risk of developing breast cancer. Environmental factors related to lifestyle and family history of breast cancer may be associated with BBD development. However, the effect of family history of breast cancer on the risk of benign breast diseases is still unclear. Objective: To evaluate the association between family history of breast cancer and benign breast diseases. Methods: This is an integrative review that selected observational studies in different databases to analyze the association between BBD and family history of breast cancer, considering the different classification criteria for both benign diseases and family history. All studies were published between 1977 and 2016. A total of 13 studies were selected, among which ten are case-control and case-cohort studies; and three are cohort studies. Most studies received high or moderate quality classification according to the Newcastle-Ottawa assessment scale. Results: Family history of breast cancer was associated with the development of proliferative lesions and the presence of atypia, and it was more closely related to the development of benign diseases in young women, with a tendency to decrease with advancing age. Conclusion: Studies suggest there may be an association between family history of breast cancer and benign breast diseases; nevertheless, no statistically significant results were found in many case-control studies, and more robust prospective research is necessary to further clarify this association.

TREATMENT OF GIANT JUVENILE FIBROADENOMA: RESULT AFTER MINIMALLY INVASIVE APPROACH WITHOUT RECONSTRUCTIVE SURGERY / Tratamento do fibroadenoma gigante juvenil: abordagem minimamente invasiva sem cirurgia reconstrutora

Fibroadenomas are common benign tumors of the female breast. Those that present as rapidly growing breast tumors exceeding 5 cm in diameter or 500 g in weight in young female patients are commonly classified as giant juvenile fibroadenomas. These tumors are rare, and due to their excessive growth, they are usually enucleated to clarify a malignant origin, to differentiate from phyllodes tumor and to prevent persisting deformities of the breast. This report details the surgical approach to this clinical problem in a 14-year-old female with functional preservation of the breast and a good esthetic result.

Fibroadenomas são tumores benignos comuns da mama feminina. Aqueles que apresentam rápido crescimento excedendo a 5 centímetros de diâmetro ou que pesam mais que 500 gramas em mulheres jovens são classificados como fibroadenomas gigantes juvenis. Estes tumores são raros e, devido seu excessivo crescimento, são comumente enucleados para descartar uma origem maligna, diferenciar de tumores filóides e para evitar deformidades da mama. Este relato de caso detalha uma abordagem cirúrgica em uma adolescente de 14 anos com preservação da mama e bom resultado estético

Observation on lower-reinforcing and upper-reducing acupuncture method for hyperplasia of mammary gland and its influence on estradiol and progesterone / 针灸推拿医学（英文版）

Objective:To observe the clinical effect of lower-reinforcing and upper-reducing acupuncture method for hyperplasia of mammary gland (HMG) and its influence on estradiol (E2) and progesterone (P).Methods:A randomized,single-blinded and controlled trial was conducted.A total of 124 cases conforming to the inclusion criteria were randomized by random number table into a treatment group and a control group,with 62 cases in each group.Patients in both groups received acupuncture therapy at the same acupoints,while patients in the treatment group received lower-reinforcing and upper-reducing method,and patients in the control group received even reinforcing-reducing manipulation.The treatment started around 10 d before menstruation and was conducted every other day.Patients received 5 treatments in each menstruation cycle for consecutive 3 cycles.The levels of E2,P and E2/P and clinical efficacy were measured before and after treatment.Results:After treatment,the breast lump size,pain intensity and concomitant symptoms score in both groups were substantially lower than those before treatment,showing statistical significances (all P＜0.01),and the improvement in the treatment group was higher than that in the control group,and the between-group comparisons showed statistical significances (all P＜0.01).After treatment,the overall effective rate was 91.9％ in the treatment group,higher than 72.6％ in the control group,and the between-group comparison showed a statistical significance (P＜0.01).After treatment,levels of E2,P and E2/P value showed no statistical significance when compared with those before treatment in the two groups (all P＞0.05).Conclusion:Lower-reinforcing and upper-reducing acupuncture method can effectively alleviate clinical symptoms and signs in HMG patients,and produce a better effect than even reinforcing-reducing manipulation.The majority of HMG patients' E2,P level and E2/P value were not beyond the normal ranges;therefore,acupuncture showed no substantial influence on E2 and P levels and E2/P value.

Mastopatía diabética: a propósito de un caso clínico / Diabetic mastopathy: a clinical case

La mastopatía diabética es una lesión fibroinflamatoria de la mama muy infrecuente, que característicamente se presenta en mujeres premenopáusicas y está fuertemente asociada a diabetes mellitus tipo I. La patogénesis es desconocida, sin embargo, histopatológicamente se ha observado una reacción en el tejido conectivo similar al de algunas enfermedades autoinmunes. La clínica y exámenes complementarios pueden ser sugerentes de neoplasia, por lo que se requiere estudio histopatológico para establecer el diagnóstico definitivo.

Diabetic mastopathy is a very infrequent fibro-inflammatory lesion generally found in pre-menopausal women and is strongly associated with type 1 diabetes mellitus. Its pathogenesis is unknown; however its histopathology shows a connective tissue reaction similar to that of some auto-immune diseases. Its clinical presentation and complementary tests may suggest neoplasm, thus definitive diagnosis requires a histopathological study.

Metaplastic Carcinoma with Chondroid Differentiation Arising in Microglandular Adenosis

Microglandular adenosis (MGA) of the breast is a rare, benign proliferative lesion but with a significant rate of associated carcinoma. Herein, we report an unusual case of metaplastic carcinoma with chondroid differentiation associated with typical MGA. Histologically, MGA showed a direct transition to metaplastic carcinoma without an intervening atypical MGA or ductal carcinoma in situ component. The immunohistochemical profile of the metaplastic carcinoma was mostly similar to that of MGA. In both areas, all the epithelial cells were positive for S-100 protein, but negative for estrogen receptor, progesterone receptor, HER2/neu, and epidermal growth factor receptor. An increase in the Ki-67 and p53 labelling index was observed from MGA to invasive carcinoma. To the best of our knowledge, this is the first case of metaplastic carcinoma with chondroid differentiation arising in MGA in Korea. This case supports the hypothesis that a subset of MGA may be a non-obligate morphologic precursor of breast carcinoma, especially the triple-negative subtype.

Therapeutic Observation of Mild Moxibustion for Hyperplasia of Mammary Glands in Female College Students of Different Constitutions / 上海针灸杂志

ObjectiveTo explore which body constitution responds the best in the treatment of hyperplasia of mammary glands with mild moxibustion, by differentiating the constitution following the self-rating scale for theClassification of Body Constitution of Traditional Chinese Medicine.MethodTotally 118 patients were intervened by mild moxibustion, majorly at Jianjing (GB21), but assisted by other points according to the nine constitution types (moderate, qi deficiency, blood stagnation, phlegm-dampness, qi stagnation, damp-heat, yin-deficiency, yang-deficiency, and specific constitutions). The mammary lump, pain in breast, and complicated symptoms were observed before and after intervention by following the self-comparison rules.ResultThere were no significant changes in mammary lumps in the 9 constitution types (P>0.05); the phlegm-dampness, qi-deficiency, blood stagnation, qi stagnation, and yang-deficiency constitutions showed significant improvements in the evaluation of breast pain and complicated symptoms (P0.05).ConclusionMild moxibustion can significantly improve the symptoms in some constitutions, but it seems that dry mild moxibustion is impossible to reverse the organic lesions and its efficacy is rather limited.

Therapeutic Observation of Paired Needling plus Tuina for Small Breast Disease / 上海针灸杂志

ObjectiveTo observe the clinical efficacy of paired needling plus tuina in treating small breast disease.MethodBy following the randomized controlled method, 60 patients with small breast disease were divided into a treatment group (intervened by paired needling plus tuina) of 30 cases and a control group (intervened by treatment device for mammary glands) of 30 cases, 15 sessions as a treatment course, for 2 courses in total. The chest circumference was used to evaluate the therapeutic efficacy.Result There was no significant inter-group difference in comparing the chest circumference after the first treatment course(P>0.05), while the difference was statistically significant after 2 treatment courses(P<0.05).ConclusionPaired needling plus seven-step tuina can produce a significant stable long-standing therapeutic efficacy in treating small breast disease.

Value of ultrasonography in diagnosis and differential diagnosis of breast sclerosing adenosis / 中华超声影像学杂志

Objective To investigate the value of color Doppler ultrasonography in diagnosis and differential diagnosis of breast sclerosing adenosis (SA).Methods Preoperative sonography in 32 SA,99 invasive ductal carcinoma(IDC),51 ductal carcinoma in situ(DCIS) and 64 fibroadenoma(FA) confirmed by pathology were retrospectively analyzed.Results The average age of SA group was younger than IDC and DCIS groups',but older than FA group's (P ＜0.05).The focal maximum diameter of SA group was the smallest among all(P ＜0.05).All the SA sonograms showed solid hypoechoic lesions,with spiculate margin was less than IDC group and larger than DCIS and FA groups (P ＜0.05).Similar ultrasonic characteristics,such as irregular shape,unclear border,acoustic halos were seen in SA and DCIS groups (P ＞0.05),while IDC group showed the highest rate and FA group had the least(P ＜0.05).SA masses' uneven internal echo,calcification,posterior acoustic attenuation was higher than FA group(P ＜0.05),but less than IDC and DCIS groups(P ＞0.05).Meanwhile,A/T ratios(≥0.7) were higher than DCIS and FA groups,but less than IDC group(P ＞0.05).In addition,SA group had a similar detection rate of the internal blood flow with FA group(P ＞0.05),but less than the IDC and DCIS groups(P ＜0.05).Conelusions Ultrasonography has a significant clinical value in diagnosis and differential breast sclerosing adenosis.

Value of contrast-enhanced ultrasound in the diagnosis of the local adenosis of breast / 中华超声影像学杂志

Objective To analyse appearances of contrast-enhanced ultrasound(CEUS) of breast local adenosis,and to explore the value of CEUS in the diagnosis of the local adenosis of breast.Methods The data of conventional ultrasound and CEUS of local adenosis of breast in 110 cases confirmed by operation and pathology were analysed.The enhancement patterns,border of the lesion,time-intensity curve were evaluated respectively.Results Totally 151 lesions were detected by conventional ultrasound in 110 cases,61 lesions were diagnosed by conventional ultrasound for adenopathy or adenosis tumor,the diagnosis coincidence rate was 40.4％ (61/151).By CEUS,106 lesions were diagnosed as adenopathy or adenosis tumor,the diagnosis coincidence rate was 70.2 ％ (106/151),higher than that of conventional ultrasound.The features of CEUS include:In contrast perfusion time to peak,103 lesions inhomogeneously enhanced in whole or in part (68.2 ％).The enhancement degree of 121 lesions (80.1 ％) were moderate enhancement or slightly high enhancement,a few lesions (11.9％,18/151) showed significantly enhanced,and very few lesions (7.9 ％,12/151) for low enhancement.In contrast perfusion peak,107 (70.9 ％) lesions had less clear boundary,no envelope,and had a certain continuity with the surrounding background breast tissue,in which 5 lesions were showed significantly increased in size by CEUS comparison with conventional ultrasound,and the boundary of 4 lesions was shaped like the burr,no regularity after enhancing.The boundary of 29.1％ (44/151) of the lesion was clear.In the lesions with moderate enhancement or slightly high enhancement,the time-intensity curve mainly displayed same washin and same wash out (60/151,39.7 ％) and fast washin and fast wash-out (65/151,43.0％).Conclusions CEUS image of focal breast adenosis has certain characteristics.CEUS can provide more evidences in diagnosis and differential diagnosis of breast adenosis,which can help to improve diagnostic confidence.

Objetivo: Determinar la importancia y utilidad del ultrasonido mamario como método de imagen complementario en pacientes con mamas densas, ACR 3 y 4. Materiales y métodos: Estudio observacional longitudinal de tipo prospectivo. Se evaluaron 483 pacientes femeninas que asistieron a la Clínica de Mamas (San Cristóbal, Estado Táchira) durante el periodo de febrero de 2010 a febrero de 2011 con mamas densas en mamografía, sin hallazgo clínico ni radiológico, con evaluación ultrasonográfica complementaria y posterior estudio histopatológico según grado de sospecha de lesión por categorización BI-RADS. Resultados: La edad promedio de las pacientes fue de 45,15 años, menarquía a los 12,57 años y mamas densas ACR 3, la mayoría sin antecedentes de cáncer de mama ni uso de terapia de reemplazo hormonal. Se diagnosticaron 304 lesiones ocultas, el 10,8% con características ultrasonográficas de sospecha y el 2,2% con hallazgos histopatológicos de malignidad. Conclusiones: Se demuestra la importancia del ultrasonido como método complementario de rastreo en pacientes con mama densa.

Objective: To determine the importance and usefulness of breast ultrasounds as supplementary imaging method in patients with dense breasts, ACR 3 and 4. Materials and methods: Prospective observational longitudinal type study. We evaluated 483 female patients in the Clínica de Mama (San Cristobal, Tachira Ste.) from February 2010 to February 2011 with dense breasts in mammography without clinical or radiological findings, with additional ultrasonographic evaluation and a histopathological study according to the degree of lesion suspicion by BIRADS categorization. Results: The average age of the patients was 45.15 years, The menarche age was 12.57 years and ACR 3 breasts. Most patients did not have a background of breast cancer, nor did they use hormone replacement therapy. 304 hidden lesions were diagnosed, 10.8% with suspicious ultrasonographic features and 2.2% with histopathological malignancy findings. Conclusions: The importance of the ultrasound as a complementary screening method is proven in patients with dense breasts.

Invasive Breast Carcinoma Arising in Microglandular Adenosis: Two Case Reports / 한국유방암학회지

Microglandular adenosis (MGA) is a rare benign disease that shows an infiltrative growth pattern of small glands, and it may progress to include atypia and carcinoma. Here we report two cases of breast carcinoma arising in MGA. Case 1 was a 44-year-old woman with a previous history of ductal carcinoma in situ in her right breast. During a follow-up, a 1.8 cm mass-like lesion was found in her left breast. An excisional biopsy suggested that the lesion was breast carcinoma. Case 2 was a 57-year-old woman with a 2.9 cm mass in her right breast. A core needle biopsy of the lesion suggested invasive carcinoma. Both patients underwent modified radical mastectomy with sentinel lymph node biopsy. Both tumors lacked a myoepithelial cell layer and stained positively for S-100, lysozyme, and alpha1-antitrypsin, which is typical of MGA. Both cases showed invasive carcinoma arising in MGA.

MR Imaging Features of Fibrocystic Breast Disease / 实用放射学杂志

Objective To analyze the MRI features of fibrocystic breast disease (FBD). Methods 39 patients with pathologically proven FBD were retrospectively reviewed. The imaging protocol consisted of pro-contrast imagings and bilateral breast volume im-aging for breast assessme NT(VIBRANT). MRI features were interpreted based on the morphologic and enhancement kinetic de-scriptors defined on ACR DIRADS-MRI lexicon. Results There were 3 types on ACR BI-RADS-MRI lexicon in FBD,including 13 focal mass-type showing malignant enhancement kinetic pattern mostly;15 cyst-type with non-enhancement or mild enhance-ment,of them,1 case with periductal mastiffs showing strong enhancement and rapid up-slope and wash-out mimicking a breast cancer. 6 non-mass type usually showing benign enhancement kinetic pattern. In 5 patients,MRI did not show definite abnormal evi-dence. Conclusion MRI is of significant value in diagnosing FBD.

Columnar Cell Lesions in Fibrocystic Change of the Breast: The Incidence and Relationship with Microcalcifications

BACKGROUND: Columnar cell lesions (CCLs) are characterized by the presence of columnar epithelial cells lining the terminal duct lobular units of the breast and frequently found in biopsies for microcalcifications. Their incidence and relationship with other lesions and the locations of microcalcifications have not been established. METHODS: We reviewed 1,038 cases of fibrocystic change (FCC) for the degrees of CCLs and ductal proliferative change (PC) and the locations of microcalcifications. RESULTS: Among 1,038 FCC cases, CCLs were found in 18.9%, columnar cell change (CCC) in 12.5%, columnar cell hyperplasia (CCH) in 5.3% and flat epithelial atypia (FEA) in 1.1%. CCLs were found in 14.2%, 28.8%, and 40.0% of non-PC (NPC), proliferative disease (PD) without atypia and PD with atypia, respectively. Microcalcifications were found in 33.5%, 56.2%, 61.8%, and 81.8% of caese without CCLs, with CCC, CCH and FEA, respectively. Their locations were in NPC in 66.3% of the cases, PD in 14.8% of the cases or both areas in 18.8% of FCC. CONCLUSIONS: The incidence of CCLs increased according to the degree of PD without positive correlation between the degree of CCLs and PD. The frequency of microcalcifications increased according to the degree of CCLs but was statistically insignificant. There is a possibility that a needle biopsy targeting a microcalcification area might leave additional PD around the targeted area because microcalcifications were found more frequently in NPC than PD area.

Infrared Radiation Temperature Comparison on Body Surface of Points Between Healthy People and Patients with Hyperplasia of Mammary Glands / 针灸推拿医学（英文版）

Objective: To compare the difference of infrared radiation temperature on body surface of points between healthy people and patients with hyperplasia of mammary glands. Method: The thermaCATMT P30 infrared thermal imaging system was selected to measure the infrared radiation temperature on body surface of eight points in four meridians in 74 patients with hyperplasia of mammary glands and 63 healthy people. Results: The infrared radiation temperatures on body surface of right Youmen (KI 21) in cases with hyperplasia of mammary glands were significantly higher than the healthy people (P=0.009), and the infrared radiation temperatures on left Youmen (KI 21) and other points had no significant difference with healthy people (P>0.05). Conclusion: The infrared radiation temperatures on body surface of right Youmen (KI 21) have significant differences with healthy people. This might occur because of the pathogenesis of hyperplasia of mammary glands and of the specificity of the point Youmen (KI 21).

Epidemiology of 10 000 mammary gland disease cases in Yangquan city / 肿瘤研究与临床
