Fibroadenoma of the breast is a benign tumor composed of a biplastic proliferation of both stromal and epithelial components. [ 12 ] [ 13 ] This biplasia can be arranged in two growth patterns: pericanalicular (stromal proliferation around epithelial structures) and intracanalicular (stromal proliferation compressing the epithelial structures ...
When horizontal x-ray beams, commonly used in lateral projections, are used to image the breast, the fluid inside the cysts, such as milk of calcium, is imaged tangentially. [2] This technique often produces linear or curvilinear patterns of calcification. In some cases, a semilunar shape may appear, which is why this sign is called "teacup sign."
Pseudoangiomatous stromal hyperplasia (PASH) is an overgrowth of myofibroblastic cells in the breast. It has an appearance similar to fibroadenomatoid changes. [1] The diagnostic significance is currently uncertain, but it appears to be benign. There have been cases of PASH diagnosed where the tumors co-exist with breast cancer.
Papillomatosis of the breast (PB) is a rare, benign, epitheliosis-like lesion, i.e. an overgrowth of the cells lining the ducts of glands that resembles a papilla (i.e. small rounded protuberance) or nipple-like nodule/tumor. PB tumors develop in the apocrine glands of the breast.
Ultrasound-guided biopsies have also been shown to decrease re-excision and mastectomy rates in breast cancer. A recent study found 100% ultrasound localization with negative margins obtained in both non-palpable and palpable lesions at initial procedure. In line with this, intraoperative ultrasound guided breast conserving surgery is being ...
The prognosis of phyllodes tumor is good with an overall 87% 10-year survival rate. [5] After wide-margin surgical excision, 98.7% of benign phyllodes tumors and 80% of borderline were cured. [25] In rare cases where the tumor has metastasized, the prognosis is poor. [5] This most commonly occurs in cases of malignant grade phyllodes tumor. [5]
A breast mass, also known as a breast lump, is a localized swelling that feels different from the surrounding tissue. [1] Breast pain , nipple discharge , or skin changes may be present. [ 1 ] Concerning findings include masses that are hard, do not move easily, are of an irregular shape, or are firmly attached to surrounding tissue.
The microscopic appearance of a nipple adenoma can be mistaken for carcinoma. [1] Other conditions that have similar symptoms and signs as nipple adenoma include Paget's disease of the breast, other intraductal papillomas, ductal carcinoma in situ (DCIS), syringomatous adenoma of the nipple and subareolar sclerosing duct hyperplasia.
