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 ...
Phyllodes tumors are part of a group of breast diseases called cellular fibroepithelial lesions. [8] This term incorporates a spectrum of diseases ranging from a benign fibroadenoma to a malignant phyllodes tumor, with numerous variants in between. [14] They are classified by ICD-O, not by MeSH. [14]
A fibroepithelial neoplasm (or tumor) is a biphasic tumor. They consist of epithelial tissue, and stromal or mesenchymal tissue. They may be benign or malignant. [1] Examples include: Brenner tumor of the ovary; Fibroadenoma of the breast; Phyllodes tumor of the breast; Sometimes fibroepithelial polyps (FEPs) of the vulva may be misdiagnosed as ...
A breast tumor is an abnormal mass of tissue in the breast as a result of neoplasia. A breast neoplasm may be benign, as in fibroadenoma, or it may be malignant, in which case it is termed breast cancer. Either case commonly presents as a breast lump. Approximately 7% of breast lumps are fibroadenomas and 10% are breast cancer, the rest being ...
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."
Fibrocystic breast changes is a condition of the breasts where there may be pain, breast cysts, and breast masses. [1] The breasts may be described as "lumpy" or "doughy". [ 3 ] Symptoms may worsen during certain parts of the menstrual cycle due to hormonal stimulation. [ 1 ]
Benign tumors of bone can be similar macroscopically and require a combination of a clinical history with cytogenetic, molecular, and radiologic tests for diagnosis. [23] Three common forms of benign bone tumors with are giant cell tumor of bone, osteochondroma, and enchondroma; other forms of benign bone tumors exist but may be less prevalent.
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.
