ABSTRACT
Introducción: El fibroadenoma es una lesión bastante común en mama, pero su localización en la región vulvar es extremadamente rara, con alrededor de sesenta casos, descritos en la literatura. Se presenta como una masa unilateral, subcutánea y asintomática, de crecimiento insidioso. El tamaño de este tipo de lesión varía entre 1 y 12 cm en los casos reportados hasta la fecha. A pesar de ser infrecuentes, las tumoraciones a nivel vulvar continúan siendo importante motivo de consulta. La histogénesis de este tipo de lesiones ha sido tema de discusión en los últimos años, sobresalen dos teorías: la presencia de tejido mamario ectópico, y la degeneración tumoral de un grupo de glándulas similares a tejido mamario, descritas como componente habitual de la región. Objetivo: Aportar un diagnóstico diferencial polémico de tumores vulvares. Presentación del caso: Se presenta una paciente de 22 años con diagnóstico histopatológico de fibroadenoma de vulva. Se realiza exéresis de la lesión, la cual al examen macroscópico midió aproximadamente 15 cm en su eje longitudinal (la más grande reportada en la literatura). Conclusiones: A pesar de su baja frecuencia de presentación, el fibroadenoma de vulva es una entidad a tener en cuenta como diagnóstico diferencial de los tumores subcutáneos de localización vulvar(AU)
Introduction: Fibroadenoma is a fairly common lesion in the breast tissue, but its location in the vulvar region is extremely rare, with about 60 specific cases in the literature. It is presented as a unilateral, subcutaneous and asymptomatic mass, with insidious growth. The size of this type of lesion is between 1 and 12 cm in the cases reported to date. Despite being infrequent, vulvar tumors continue to be important reasons for medical consultation. The histogenesis of this type of lesions has been the subject of discussion in recent years; two theories stand out: the presence of ectopic breast tissue, and tumor degeneration of a group of glands similar to breast tissue described as a common component of the region. Objective: To providea polemic differencial diagnosis of vulvar tumors. Case presentation: We present a 22-year-old patient with histopathological diagnosis of vulvar fibroadenoma. Excision of the lesion was performed, which at the macroscopic examination measured approximately 15 cm in its longitudinal axis (the largest reported in the literature). Conclusions: Despite its low frequency of presentation, vulvar fibroadenoma needs to be considered as differencial diagnosis of vulvar tumors(AU)

ABSTRACT Ectopic breast tissue (EBT) occurs in 0.3-6% of females and is typically located in the axilla, but it can also be found in the vulva. Diagnosis often occurs when there are hormonal changes that influence growth and development of the tissue. Due to symptomatology and malignant potential of this ectopic tissue, excision is typically recommended. We present the case of a 31-year-old woman, gravida 1 para 1001, attended four weeks after a normal vaginal delivery for a painless vulvar mass. Incision, drainage and biopsy were performed, revealing ectopic breast tissue with lactational changes. Simple partial vulvectomy revealed fibrocystic and lactational changes in mammary tissue of the vulva without atypia or malignancy. Our case displays a rare finding of aberrant, lactating breast tissue presenting in a postpartum patient.
RESUMEN El tejido mamario ectópico (TME) ocurre en 0,3 a 6% de las mujeres y generalmente se localiza en la axila, pero también puede ser encontrado en la vulva. El diagnóstico a menudo ocurre cuando hay cambios hormonales que influyen en el crecimiento y desarrollo del tejido mamario. Generalmente, se recomienda la escisión debido a la sintomatología y al potencial maligno de este tejido ectópico. Presentamos el caso de una mujer de 31 años de edad, grávida 1 para 1001 que fue evaluada por una masa vulvar indolora cuatro semanas después de un parto vaginal. Se realizó incisión, drenaje y biopsia de la masa, obteniendo 30 mL de líquido lechoso. El resultado de la biopsia reveló tejido mamario ectópico con cambios de lactancia. La paciente fue sometida a vulvectomía parcial simple que mostró cambios fibroquísticos y de lactancia en el tejido mamario de la vulva, sin atipia ni malignidad. Nuestro caso es un hallazgo raro de tejido mamario aberrante en una paciente posparto.
ABSTRACT
Breast tissue expanders (TEs) with magnetic infusion ports are labeled “MR Unsafe.” Therefore, patients with these implants are typically prevented from undergoing magnetic resonance imaging (MRI). We report a patient with a total submuscular breast TE who inadvertently underwent an MRI exam. She subsequently developed expander exposure, requiring explantation and autologous reconstruction. The safety profile of TEs with magnetic ports and the use of MRI in patients with these implants is surprisingly controversial. Therefore, we present our case report, a systematic literature review, and propose procedural guidelines to help ensure the safety of patients with TEs with magnetic ports that need to undergo MRI exams.

OBJECTIVE: To observe the effect of acupuncture combined with medication (Rule Granule) on serum prolactin (PRL)，estradiol (E2) and progestone (P) contents and expressions of prolactin receptor (PRLR), estrogen receptor (ER) and progestrone receptor (PR) proteins in mammary gland (MG) tissues of MG hyperplasia (MGH) rats, so as to explore its mechanisms underlying improvement of MGH. METHODS: A total of 55 female SD rats were randomized into blank control group (n＝10), model group (n＝10), acupuncture group (n＝11), medication group (n＝10), and acupuncture plus medication group (n＝9). The MGH model was established by muscular injection of E2 benzoate(0.5 mg/kg, once daily for 20 days), followed by injection of P (5 mg/kg) into the lateral muscle of the hind-limb, once daily for 5 days, and the rats of the control group were treated by muscular injection of normal saline at the same site and in the same procedures. Acupoint group A composed of bilateral Tianzhong (SI 11), Ganshu (BL 18) and Zusanli (ST 36), and group B composed of Tanzhong (CV 17), and bilateral Wuyi (ST 15) and Hegu (LI 4) were alternatively punctured with filiform needles and stimulated swiftly by twirling the needle in each acupoint for 20－30 sec, once daily for 30 days. Rats of the medication group and acupuncture ＋medication group were treated by gavage of Rule Granule fluid containing Baishao (Paeonia Iactiflora Pall), Danggui (Angelica sinensis), etc. (1.5 mL/100 g for each rat) and those of the other groups treated by gavage of distilled water (1.5 mL/100 g). The treatment was given once daily for continuous 30 d. At the end of the experiments, the rats' abdominal aorta blood was collected for assaying the contents of serum PRL, E2 and P with ELISA, and the pathological changes of breast tissue (the left 2nd pairs) were observed under microscope after sectioning and H．E. staining. The expression of PRLR, ER and PR proteins in the breast tissue was detected by immunohistochemistry. RESULTS: After modeling, the hyperplasia of mammary gland in the model group was obvious; the serum PRL and E2 contents and the immunoactivities of PRLR, ER and PR were significantly increased (P0.05)．. CONCLUSION: Acupuncture, Rule Granule, and acupuncture combined with Rule Granule can improve hyperplasia of mammary gland in rats, which may be related to their effects in reducing serum PRL and E2 and breast ER, PR and PRLR expression levels, and in increasing serum P level. The therapeutic effects of acupuncture plus Rule Granule are better than those of simple acupuncture and simple Rule Granule.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of acupuncture combined withgranule on breast tissue, prolactin(PRL) and prolactin receptor (PRLR) expression in rats with mammary gland hyperplasia (MGH), and to explore its action mechanism to provide reference for clinical treatment of MGH.</p><p><b>METHODS</b>Fifty-five female SD rats were randomly divided into a blank group, a model group, an acupuncture group, a Rule granule group and a combination group. Except the blank group, the rats in the remaining groups were treated with combined stimulation of estrogenic and progestational hormone to establish MGH model. After model establishment, the rats in the acupuncture group were treated with acupuncture at Plan A of "Tianzong" (SI 11), "Ganshu" (BL 18), "Zusanli" (ST 36) and Plan B of "Wuyi" (ST 15), "Hegu" (LI 4), "Danzhong" (CV 17). Each plan was selected for one acupuncture treatment, and two plans were used alternately. The rats in the Rule granule group were treated with oral administration of granule, 3 mL per times. The rats in the combination group were treated with the samegranule, followed by acupuncture, once a day. After consecutive 30-day treatment, blood sample was collected from abdominal aorta; ELISA method was applied to measure the contents of PRL; the HE slice of mammary gland was observed under light microscope; the SABC immunohistochemical method was applied to measure the positive expression of PRLR.</p><p><b>RESULTS</b>The morphology of breast tissue in the model group was consistent with MGH. Compared with the blank group, the serum PRL and the expression of PRLR were increased significantly in the model group (both<0.01). Compared with the model group, the hyperplasia of mammary gland in each treatment group was improved, and serum PRL and expression of PRLR were significantly reduced (<0.05,<0.01), which were more significant in the combination group (both<0.05).</p><p><b>CONCLUSION</b>Acupuncture,granule and its combination could effectively treat MGH, which is likely to reduce the level of serum PRL and inhibit the binding of PRL to PRLR, as a result, the level of Eis indirectly inhibited, and the hyperplastic mammary gland is recovered. Compared with acupuncture orgranule, the combination of both has better overall efficacy.</p>
ABSTRACT
Objective To investigate the relationship between adenosine triphosphate-binding cassette superfamily G member 2 (ABCG2) mRNA and protein expressions and chemotherapeutic efficacy and drug resistance in breast cancer patients. Methods 24 patients with breast cancer were selected as study subjects, all patients were treated with anthracycline chemotherapy after chemotherapy, according to WHO criteria, the patients were divided into effective group, stable group and advanced group according to chemotherapy effect. The levels of ABCG2 mRNA and protein in the breast tissue were detected by qPCR and ELISA before and after chemotherapy. Results After chemotherapy, the total effective rate was 41.67%, 58.33% of patients still developed drug resistance. The expressions of ABCG2 mRNA and protein in patients after chemotherapy were significantly higher than those before chemotherapy (P<0.05). The expressions of ABCG2 mRNA and protein were significantly lower in the effective group than in the stable group and advanced group (P<0.05). The expressions of ABCG2 mRNA and protein in the stable group was significantly lower than that in the advanced group (P<0.05). Conclusion The expression level of ABCG2 was correlated with the chemotherapeutic efficacy and drug resistance of breast cancer patients. The higher the ABCG2 expression level, the stronger the ability of promoting the excretion of drugs, the more significant the drug resistance of tumor cells and the worsen the chemotherapy effect.
ABSTRACT
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.

Background: The aim of the current study is to evaluate the anti-tumor activity of saponins isolated from the roots of Momordica cymbalaria (MC) against dimethylbenz[a]anthracene (DMBA) induced rats. Methods: A steroidal saponin MC (SMC) was isolated from MC fenzl and purified by preparative high-performance liquid chromatography. Breast cancer was induced in 50-day-old female Sprague-Dawley rats by injecting DMBA (6 mg/kg intravenous) in three doses on day 50, 54, and 57. The rats were randomized into four groups; control, DMBA, SMC (100 mg/kg), and tamoxifen (6.6 mg/kg) to DMBA breast cancer rats. The tumor size, volume, hormonal, antioxidant, and whole mount parameters were estimated. Results: Mean tumor size and volume, luteinizing hormone, and progesterone with superoxide dismutases, catalase, and glutathione levels increased significantly (p<0.001); serum estradiol, follicle stimulating hormone with lipid peroxidation decreased significantly (p<0.001) in DMBA-induced breast cancer and vice versa in SMC and tamoxifen. Terminal end buds, terminal ducts, alveolar buds, and lobules decreased significantly (p<0.001) in DMBA-induced breast cancer whereas increased significantly in SMC and tamoxifen. Histological necrosis and hemorrhage along with focal desmoplastic reaction in DMBA-induced breast cancer; ductile elongation and hyperplasia of both ducts and alveoli were prominent, with increased secretory activity in SMC group. The results confirmed the chemopreventive effect of SMC and tamoxifen in DMBA-induced breast cancer. Conclusions: The SMC exhibited anti-tumor activity against mammary cancer, which may be due to its anti-estrogenic, antioxidant activity.

Aberrant breast tissue is a subset of accessory breast tissue, and it exhibits similar consistency to that of the adjacent normal breast tissue, but it lacks an associated nipple complex. It is a developmental anomaly defined as the persistence of breast tissue along the embryonic mammary line. Aberrant breast tissue is most commonly located in the axilla, though it may be present anywhere along the embryonic mammary line. We report here on an 11-year-old girl with aberrant breast tissue and acanthosis nigricans. She had tender masses that became noticeable with the onset of menarche and mottled hyperpigmentation on both axillae. The histopathologic finding of the lesion revealed the typical features of aberrant breast tissue with acanthosis nigricans.

Nos últimos três anos foram realizadas 30.000 mamografias no Departamento de Diagnóstico por Imagem da Universidade Federal de São Paulo/Escola Paulista de Medicina, sendo que em 0,23% delas foi observado tecido mamário acessório. Relatamos um caso de paciente de 44 anos de idade, feminina, que apresentava nódulo endurecido, aderido ao subcutâneo, em topografia inframamária à direita. À ultra-sonografia observou-se imagem nodular sólida hipoecogênica, com contornos irregulares, medindo 1,4 cm. À ressonância magnética visualizou-se curva de realce tipo II (platô). Após biópsia, foi diagnosticado denocarcinoma mamário. O carcinoma nas mamas acessórias costuma apresentar aspecto histopatológico indiferenciado e disseminação mais precoce, determinando pior prognóstico. Por este motivo, é de fundamental importância sua detecção nos estágios iniciais, permitindo, dessa forma, a instituição precoce do tratamento e possibilitando maiores chances de cura.
Over the last three years 30,000 mammograms were performed in the Department of Diagnostic Imaging of Universidade Federal de São Paulo/Escola Paulista de Medicina. Accessory breast tissue was observed in 0.23% of the individuals. We report a case of a 44-year-old woman presenting a hard nodule adhered to the subcutaneous tissue in right inframammary topography. At ultrasonography, a hypoechogenic solid nodule with irregular contour measuring 1.4 cm was observed. Magnetic resonance imaging showed type II (plateau) dynamic curve. Breast adenocarcinoma was subsequently diagnosed by biopsy. Accessory breast carcinomas generally present with an ill-defined histopathological aspectand early dissemination. Early detection is essential to begin treatment in the initial stages, with better chances of cure.

Fibroadenoma is a rare lesion of the vulva. It has been proposed that the origin of the tissue is either ectopic breast tissue or vulvar mammary-like glands (MLG). We report a case of vulvar fibroadenoma in a 33-year-old woman with a right vulvar mass presenting clinically as vulvar cyst. The cut surface of the tumor showed a white and homogenous appearance that was 2.5 cm in maximum dimension. Microscopically, the lesion was well-circumscribed but non-encapsulated. It revealed nodular, glandular and stromal proliferation, consistent with fibroadenoma of breast. Immunohistochemical staining for the estrogen receptor and progesteron receptor revealed nuclear positivity in the epithelium. Smooth muscle actin confirmed the presence of a myoepithelial cell layer. Staining for pancytokeratin showed epithelial cytoplasmic positivity.

Accessory breast tissue of the axilla is one of the varieties of supernumerary breast tissue, which is observed after puberty. The tissue is capable of developing identical pathophysiologic changes as normal breast tissue. The pathologic findings of the accessory breast tissue were classified as normal breast tissue, cystic disease, chronic mastitis, atypical ductal hyperplasia, and fibroadenoma. Among these, the fibroadenoma is relatively uncommon. We have experienced a case of fibroadenoma arising in the accessory breast tissue of the axilla. A 28-year-old woman had a 8-month history of 1.5x1.3cm and 1.1x1.2cm sized firm nodules, deeply located in subcutaneous tissue on the left axilla. The size of the lesion was constant. However, she complained of mild tenderness at every premenstrual period. The histopathologic finding of the lesion revealed the typical features of fibroadenoma with accessory breast tissue.

As a consequence of the incomplete resolution of embryologic mammary ridges, ectopic breast tissue can be present anywhere along the "milk line", including the axillary region. Aberrant breast tissue can develop with any disease that affects the normal breast, including a breast carcinoma. A carcinoma of aberrant breast tissue is rare, but should still be investigated and treated properly with respect to other breast cancers in the embryonic milk-line. Herein is reported our recent experience of a carcinoma originating from aberrant breast tissue in the right axilla. An abnormal nodule around the periphery of the normal breast should be suspected as a breast carcinoma and differential diagnosis and properly treated.

Ectopic breast tissue may be seen along a diagonal line drawn from axilla to groin and it is rare with only a few reports in the world. There is a relatively frequent occurrence of ectopic breast tissue close to the breast or in the axilla, but the vulvar location is rare. We experienced a case of ectopic breast tissue in the vulva and reported it with brief review of literatures.

Accessory breast tissue is a developmental anomaly defined as persistence of breast tissue along the embryonic mammary line in the mid-thoracic region. Rarely, an abnormally located remnant of the line persists and develops into completely formed mammary glands. A 61-year-old woman presented with a pedunculated mass on the mid-lower abdomen, below the umbilicus. She detected a pea-sized nodule a few decades ago and it gradually enlarged since 1 year ago. There was no pigmented prominence resembling a nipple. Histological finding revealed lobules of the breast forming islands of glandular tissue. We believe this is an unusual case of accessory breast tissue mimicking soft fibroma as a pedunculated mass.

Accessory axillary breast tissue has received little attention in the surgical literature although it is not an uncommon kind of aberrant breast tissue. Twenty-six patients who have been treated with an exicision of accessory breast tissue from January 1988 to June 1995 at the Department of Surgery, College of Medicine, Soonchunhyang University were analyzed retrospectively. The age of the patients ranged from 18 to 58 years, median age, 34 years. All were female including two postmenopausal females. We observed a palpable mass in the left axillae in 6 patients, in the right axillae in 8 patients and in the both axilla in 12 patients. Of the 41 masses of 26 patients, 19 masses were located on tne anterior axillary line, 20 masses on the midlle axillary line and 2 masses on the posterior axillary line. The size of the accessory breast tissue ranged from 0.5 to 8cm, with a median of 3.4cm. The presenting symptoms were mass in all cases, pain in 12 cases, growing mass in 4 cases and redness in one case. Histological diagnosis of total 41 masses revealed 28 normal breast tissue, 9 fibrocystic disease, 1 ductal ectasia, 1 fibroadenoma, 1 fibrocystic disease with ductal ectasia and 1 infiltrating ductal carcinoma. There were no typical clinical characteristics for differential diagnosis preoperatively. Of a total of 38 excisional operations, 4 complications developed (two hematoma, one wound infection and one skin tag). The postoperative hospital stay ranged from 1 to 17 days. The accessory breast tissue might be regarded as a more important disease than before, because various pathologic changes could occur in it including malignant change. Early diagnosis and correct excision are usually recommended.

Cerebriform intradermal melanocytic nevus is a cause of cutis veticis gyrata, a morphologic term which describes the hypertrophy and folding of the skin, typically occurring on the scslp, to present a gyrate or cerebriform appearance. We report a 37-year-old woman with a 17 x 22cm soft, convoluted mass over most of the occipital, parietal, and temporal scalp. At birth, she had a small brownish macide on the occipital scalp that enlarged to form this extensive lesion. Histologically, nests of nevus cells were shown in the upper and the mid dermis.

We have experienced a case of the more unusual form of supernumerary breast tissue which is characterized by the presence of aberrant gland tissue alone. The case was a 30-year-old female patient in puerperium with bilateral axillary masses of seven years duration. Gentle pressure over the right-sided one caused milk to exude from a skin pore. Histopathologic findings of the tumors revealed the lobules of the breast forming islands of glandular tissue.
