In addition, larger masses can stretch the overlying breast tissue leading to nipple retraction, chest wall fixation, and in advanced cases, ulceration from pressure necrosis. [ 6 ] Phyllodes tumors can grow to a variety of sizes, ranging from 0.8 to 40 cm, with the average tumor growing to between 4 and 8 cm. [ 7 ] Their growth can be slow ...
Usual ductal hyperplasia (UDH) is a benign lesion of the breast wherein cells look very similar to normal. It is a spectrum of changes that can range from minimal stratification of cells to proliferations that are just short of atypical ductal hyperplasia .
Traditional methods of evaluating breast masses include radiological assessments (e.g. mammography, ultrasound, MRI) and pathologic analyses (e.g. fine-needle aspiration cytology, core biopsy). [10] During early work-up stages to evaluate suspicion of a breast mass—such as mammography imaging due to a palpable mass—triple test score was ...
FNAC can be performed under palpation guidance (i.e., the clinician can feel the lesion) on a mass in superficial regions like the neck, thyroid or breast; FNAC may be assisted by ultrasound or CAT scan for sampling of deep-seated lesions within the body that cannot be localized via palpation. FNAC is widely used in many countries, but success ...
Medullary breast carcinoma is a rare type of breast cancer [1] that is characterized as a relatively circumscribed tumor [2] with pushing, rather than infiltrating, margins. It is histologically characterized as poorly differentiated cells with abundant cytoplasm and pleomorphic high grade vesicular nuclei. [ 3 ]
Anatomical pathology (Commonwealth) or anatomic pathology (U.S.) is a medical specialty that is concerned with the diagnosis of disease based on the macroscopic, microscopic, biochemical, immunologic and molecular examination of organs and tissues.
Comedocarcinoma is a kind of breast cancer that demonstrates comedonecrosis, which is the central necrosis [1] of cancer cells within involved ducts. Comedocarcinomas are usually non-infiltrating and intraductal tumors, characterized as a comedo -type, high- grade ductal carcinoma in situ (DCIS).
Although tubular carcinoma has been considered a special-type tumor, [a] recent trend has been to classify it as a low-grade, invasive NOS carcinoma because there is a continuous spectrum from pure tubular carcinomas to mixed NOS [b] carcinomas with tubular features, depending on the percentage of the lesion that displays tubular features.
