Introduction Ectopic mammary tissue is consecuence of the incomplete involution of the mammary crest. The most frequent location is the axillary region and more common in women. Our gol was present the case of an infrequent pathology in its location. Materials and Method A case of a 39-year-old patient with a diagnosis of ectopic breast cancer in the left axillary region. Results We present the study and surgical resolution of a patient with ectopic breast cancer. Discussion Ectopic breast tissue occurs in 2-6% of the general population. This tissue undergoes pathophysiological changes similar to those of the normal breast, among which malignancy is found. The primary carcinoma of this tissue is infrequent and its most common manifestation is the palpable tumor. Conclussion The incidence of carcinoma in ectopic tissue is approximately 0.3% of all breast cancers. Treatment should follow the same recommendations as those for breast tumors with the same TNM stage.

Pleomorphic Adenoma of the Accessory Axillary Breast: A Rare Case Report

Pleomorphic adenoma (PA) is the most common tumor type in the salivary gland. PA is uncommon in the breast tissue. Only 73 cases of PA of the breast have been reported in the world literature. But no case in the accessory axillary breast has been reported so far. It is most commonly seen in postmenopausal women and is characterized by an admixture of epithelial and myoepithelial cells embedded in abundant myxomatous stroma. Its clinical and histologic appearance can be challenging and may lead to a misdiagnosis of invasive carcinoma. We report a case of pleomorphic adenoma (benign mixed tumor) of the accessory axillary breast, which is an extremely rare location for this tumor.

Sclerosing Adenosis in Axillary Supernumerary Breast: A Case Report

Swellings in the axilla especially in women are always viewed with suspicion owing to a large number of these being associated with breast carcinoma presenting as nodal metastasis. In a country like India, tuberculous lymphadenopathy is also amongst the first differentials. We present a case of a woman with left sided axillary swelling which on Fine Needle Aspiration Cytology (FNAC) turned out to be sclerosing adenosis of the accessory axillary breast. Accessory breasts may present as asymptomatic masses or cause symptoms such as pain or restriction of arm movements. Both benign and malignant tumors can arise in accessory breasts. So far cases of fibroadenoma and carcinoma breast have been reported but sclerosing adenosis has never been reported. Accessory breasts as mass in the axilla may prove to be a diagnostic challenge for surgeon. FNAC being an easy and accurate technique can be very helpful in differentiating such lesions.

Cáncer en mama axilar: revisión de la literatura a propósito de un caso / Axillary breast cancer: clinical case and literature review

El tejido mamario ectópico se desarrolla debido a la involución incompleta de la cresta mamaria, de localización más frecuente en la axila y más común en mujeres. Este tejido sufre cambios fisiopatológicos similares a los de la mama normal, entre los cuales se encuentra la malignización. El carcinoma primario de este tejido es infrecuente, y su manifestación más común es la masa palpable. Al igual que en la mama normal, la histología más frecuente del cáncer de mama ectópica es el Carcinoma Ductal Infiltrante y, por su localización atípica, suele diagnosticarse tardíamente, y tendría un curso más agresivo y de peor pronóstico, dado por la mayor cercanía a ganglios, piel y pared torácica. Debido a los pocos datos publicados, el diagnóstico y tratamiento no están bien establecidos, pero los esquemas disponibles son similares a los utilizados en el cáncer de mama normal. Se presenta el caso de una paciente de 41 años, con diagnóstico de cáncer de mama ectópica en la región axilar derecha, sin invasión a distancia, tratada con cirugía, quimioterapia y radioterapia, que evoluciona favorablemente, sin metástasis ni recidivas durante seguimiento.

Ectopic mammary tissue develops due to the incomplete involution of the mammary crest, which is more frequently located in the axilla and more common in women. This tissue undergoes pathophysiological changes similar to those of the normal breast, among which malignancy is found. The primary carcinoma of this tissue is infrequent and its most common manifestation is the palpable mass. As in the normal breast, the most frequent histology of ectopic breast cancer is the Infiltrating Ductal Carcinoma and, because of its atypical location, it is usually diagnosed late and it would have a more aggressive course and a worse prognosis, due to the greater proximity to lymph nodes, skin and chest wall. Because of the few published data, the diagnosis and treatment are not well established, but the available schemes are similar to those used in normal breast cancer. We present the case of a 41yearsold female patient with a diagnosis of ectopic breast cancer in the right axillary region, without distant invasion, treated with surgery, chemotherapy and radiotherapy, whoevolves favorably, without metastasis or relapses during follow-up.

Carcinoma en tejido mamario ectópico axilar con diferenciación neuroendocrina: reporte de un caso / Carcinoma in ectopic axillary breast tissue with neuroendocrine differentiation: case report

Presentar un caso de carcinoma en tejido mamario ectópico axilar. Paciente femenina de 38 años de edad, quien consultó por aumento de volumen y nódulo en región axilar de un año de evolución y punción aspiración por aguja fina previa no diagnóstica. En la evaluación se observó mamas axilares bilaterales, palpando en la derecha tumor duro de superficie irregular, se realizó mamografía, C y biopsia por aguja gruesa. Por el diagnóstico de la biopsia por aguja gruesa, se practicaron estudios de extensión y se trató con neoadyuvancia y cirugía. El estudio histopatológico de la pieza quirúrgica concluyó carcinoma ductal infiltrante con patrón neuroendocrino y metástasis en 2 de 18 ganglios, recibió adyuvancia y se mantiene libre de enfermedad

A case of female patient 38 years of age, who consulted for increased volume and axillary node in a year of evolution and prior non-diagnostic FNA. The evaluation noted bilateral axillary breasts, feeling hard lump on the right an irregular surface, we performed mammography, PAAF and core needle biopsy. For the diagnosis of the biopsy needle, extension studies were performed and treated with neoadjuvant therapy and surgery. Histopathological examination of the surgical specimen concluded infiltrating ductal carcinoma neuroendocrine pattern and metastatic in 2 of 18 nodes, received adjuvant therapy and remains free of disease

Surgical Excision of Accessory Axillary Breast Tissues

BACKGROUND: Accessory axillary breast tissue is present in approximately 2% to 6% of women, but receives little attention in the surgical literature. Furthermore, a carcinoma, as well as other pathologic changes, can arise within accessory axillary breast tissue. METHODS: Between January 1990 and December 1997 at our clinic, 83 patients underwent surgical removal of accessory axillary breast tissue. All the patients were female, and the ages ranged from 14 to 57 years, with a median of 33.8. The clinical characteristics, indications, and techniques of surgical removal, pathologic findings, and postoperative results were analyzed. RESULTS: The major clinical manifestations were axillary mass (95.2%), pain and/or tenderness (41%), and cyclic change of size (21.7%). In most patients, these symptoms appeared first during puberty (25.3%) and pregnancy (43.4%). On examination, the mass was in the right axilla in 35 patients (42.2%), the left axilla in 19 patients (22.9%) and both axillae in 29 patients (34.9%), and 3 patients had rudimentary accessory nipples. Surgical removal was performed for cosmetic problems (61.5%), clinical symptoms (21.7%), and suspicion of pathologic lesions (9.6%). The excised breast tissue varied in size from 2.5 cm to 14 cm with a median of 6.2 cm. The pathological findings demonstrated ductal dilatation in 21 patients (25.3%), chronic inflammation in 4 patients (4.8%), fibrocystic changes in 3 patients (3.6%) and lactating adenosis in 2 patients (2.4%). Postoperative complications developed in 8 patients (8.3%), and seroma was the most common. In our study, none of the patients experienced recurrence of disease, and 96.4% of the patients enjoyed cosmetically satisfying outcomes. CONCLUSIONS: In conclusion, from our experience, the treatment of choice for accessory axillary breast tissue is surgical removal, which eliminates the clinical symptoms and the aesthetical deformity and provides tissue to rule out any pathologic changes including malignancy. For cosmetically satisfying outcomes, a scar hidden from sight and balanced shapes of both axillae should be kept in mind during the operation.

Carcinoma of the axillary breast

Axillary breast is one of the varieties of polymastia which is characterized by the presence of more than 2 breasts. It may cause symptoms during pregnancy, lactation, or in the premenopausal period. Unless there are obvious symptoms of lactation or the assistance of further imaging studies such as mammography and breast ultrasound, the diagnosis is often confused with subcutaneous lipoma. The incidence of axillary breast cancer is low but it should be investigated and treated properly in view of another breast cancer in the embryonic milk-line. In this paper we reviewed 4 cases of axillary breast cancer and documented some articles regarding aberrant breast and carcinoma arising from it. It is suggested that subcutaneous nodules of uncertain origin around the periphery of the breast should be viewed with suspicion and treated properly.

A Case of Cerebriform Intradermal Melanocytic Nevus / 대한피부과학회지

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.

Accessory Axillary Breast Tissue / 대한피부과학회지

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.
