“…The presence of popular lesion along embryonic mammary ridge, showing acanthosis and basal layer pigmentation in the microscopic examination were highly suggestive for the lesion to be supernumerary nipple and characteristic histopathological features of syringomatous adenoma were evident as previously described. In contrast to case of syringomatous adenoma in the supernumerary breast [5] that showed normal breast ducto tubular structures intimate to neoplastic lesion, no evidence of glandular components or normal breast tissue was identified in our patient.…”

“…Low-grade mammary malignancies including tubular carcinoma or lowgrade adenosquamous carcinoma and primary skin tumor such as microcystic adnexal carcinoma should be differentiated from syringomatous adenoma. [5] In particular, cases such as our case both primary breast lesions and cutaneous neoplasms should be considered in the differential diagnosis. The clinical history and presence of benign breast structures in supernumerary breast tissue are helpful diagnostic features.…”

“…While the most common site is the axillary area [2], ectopic breast tissues can also be found in the scapula, thigh, and labia majora [3]. These accessory breast tissues may consist of one or any combinations of the nipple, areola, and breast parenchyma [7] and can undergo physiologic changes such as swelling, tenderness, and secretion during puberty, pregnancy, and lactation, as is the case with normal breasts [8]. Accessory breast tissue can also undergo pathologic changes both benign and malignant from fibroadenoma and [9] intraductal papilloma [10] to carcinoma formation.…”

Background: During embryogenesis, bilateral thickening of ectoderm from anterior axillary folds to inguinal folds, called mammary ridges or milk lines, develops into breast tissues. Only a pair in the pectoral area is spared from regression and continuously develops into normal breasts. Accessory breasts can result if the regression process is incomplete. These ectopic breasts can change physiologically and pathologically similar to normal breasts. Unsurprisingly, they are capable of turning malignant. Reported cases show the most common area for accessory breast cancer to be the axillary area. We report a rare case of accessory breast cancer over the costal ridge. Case presentation: We present the case of a 51-year-old Asian woman who complained of an enlarged mass lower to her left breast developed over the period of 3 months while on contraceptive pills. Unaware that the mass could be an accessory breast, the primary doctor had prescribed oral contraceptives. After our patient had noticed that the mass was obviously growing, she decided to consult a surgeon as the mass continued to grow. Expected to be benign, the mass was investigated by ultrasonography and then excised surgically. A pathology report identified the mass to be a carcinoma of the ectopic breast tissue. However, sentinel lymph node biopsy showed no nodal metastasis of all four lymph nodes. Following surgery, she received chemotherapy, radiation, and antihormonal treatment. After 2 years of postoperative follow up, she remained free of disease. Conclusions: This patient was diagnosed as having accessory breast cancer which presented with a subcutaneous mass. As this condition is exceptionally rare but curable by early treatments, we recommend surgeons to consider potential malignancy when patients present with a subcutaneous mass.

“…A number of different neoplasms, both benign and malignant, have been found in axillary breast tissue. The most common of these tumors reported in the literature is a fibroadenoma, and there are scattered case reports of other tumors including phyllodes tumor and mammary carcinoma [8]. …”

Nipple adenoma arising from axillary accessory breast: a case report

Nipple adenoma is a relatively rare benign breast neoplasm, and cases of the disease arising from the axillary accessory breast have very seldom been reported in the English literature. We report a case of nipple adenoma arising from axillary accessory breast including clinical and pathological findings. An 82-year-old woman presented with the complaint of a small painful mass in the right axilla. Physical examination confirmed a well-defined eczematous crusted mass that was 8 mm in size. The diagnosis of nipple adenoma was made from an excisional specimen on the basis of characteristic histological findings. Microscopic structural features included a compact proliferation of small tubules lined by epithelial and myoepithelial cells, and the merging of glandular epithelial cells of the adenoma into squamous epithelial cells in the superficial epidermal layer. Because clinically nipple adenoma may resemble Paget’s disease and pathologically can be misinterpreted as tubular carcinoma, the correct identification of nipple adenoma is an important factor in the differential diagnosis for axillary tumor neoplasms.Virtual slidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1186821489769063
