Color Doppler can help in distinguishing inflammatory lymph-nodes, which show increase in arborization of the hilar vessel, from non-enlarged or aspecific metastatic lymph-nodes, whose cortical sinusoids contain tumoral cells that stimulate the formation of characteristic transcapsular vessels.

Giant fibroadenomas of the breast Juvenile or giant fibroadenoma is a rare pathology usually presenting in adolescent and young girls 10—18 years old that is characterized by massive and rapid enlargement of an encapsulated mass .
Color Doppler ultrasonography for treatment response prediction and evaluation in breast cancer. Fibroadenoma is a common benign breast lesion and results from the excess proliferation of connective tissue.
Giant juvenile fibroadenoma of the breast: a clinical case.
Juvenile or giant fibroadenoma is a rare pathology usually presenting in adolescent and young girls 10—18 years old that is characterized by massive and rapid enlargement of an encapsulated mass . Number of vessels, blood-flow velocity, and intra-tumoral vessel resistance did not permit clear differentiation between malignant and benign tumors . The risk of malignant transformation is extremely low and has been reported to range around 0.
Malignant tumors have a tendency to show increased vascularization, but avascular tumors may be found as well as hypervascular benign tumors. They are benign lesions with minimal or no malignant potential.
The vessel architecture of malignant tumors is known from pathologic studies: In the first studies it was emphasized as signals were more numerous and stronger in breast tumors [1,2]. Phyllodes tumors are rare fibro-epithelial neoplasms; they may be classified as benign, borderline or malignant according to histological assessment of mitotic index, stromal hypercellularity and pleomorphism, and well circumscribed or invasive borders efografia.
Open in a separate window. Sometimes a thin echogenic rim pseudocapsule may be seen sonographically. Typically seen as a well-circumscribed, round to ovoid, or macrolobulated mass with generally uniform hypoechogenicity.
Phyllodes tumors Phyllodes tumors are rare fibro-epithelial neoplasms; they may be classified as fibroadnoma, borderline or malignant according to histological assessment of mitotic index, stromal hypercellularity and pleomorphism, and well circumscribed or invasive borders [6—8].
Associated Data Supplementary Materials mmc1. Thank you for updating your details. Color Doppler ultrasound is a valuable or sometimes problem-solving tool in a lot of breast ecografi and its usefulness also in the male breast is out of doubt [14,15].
Complicated cysts need to be distinguished from quite anechoic malignant lesions such as medullary carcinomas, metastases to the breast or intra-mammary metastatic lymph-nodes: These lesions are easily biopsied under ultrasound guidance.
It contains epithelium and has minimal malignant potential 8. Finroadenoma article Share article View ecoografia history. Although they can be located anywhere in the breast, there may be a predilection for the upper outer quadrant.
Evaluation of tumor response to neoadjuvant chemotherapy. Incidence decreases after 40 years 4. In complex cysts the demonstration of one or more fibrovascular stalks Fig.

Here below are presented examples where Color Doppler is valuable. US shows a complex mass A with rich vascularization B. Now we know that this is not true in all instances [3,4].
Color Doppler ultrasonography of the breast. In acute mastitis Color Doppler shows hyperemia in superficial cellulitis as well as around infected galactoceles or along infected ducts deeply in the breast. US scan reveals a hypoechoic mass A with rich vascularization B.
They usually occur in women between the ages of 10 and 40 years. Finally, Doppler is very useful for ultrasound-guided breast biopsy because permits to avoid the sampling of the most vascularized part of the lesion. Overlapping is not uncommon with some benign tumors that are hypervascular.
Giant juvenile fibroadenoma of the breast: a clinical case.
Abstract Has color Doppler a role in the evaluation of mammary lesions? Radiologia Diagnostica 1, Milan, Italy.
Epub Jan US shows intracystic mural nodule with fibrovascular stalk in the solid components histological analysis: Log in Sign up. A maximum diameter of 2. They are assumed to be aberrations of normal breast development ANDI or the product of hyperplastic processes, rather than fibroadenpma neoplasms. The incidence of metastases is strictly correlated to the degree of histologic aggressiveness.
Fibroadenomas can be stimulated by estrogen and progesterone. Journal List J Ultrasound v.
It fibroaeenoma the most common breast mass in the adolescent and young adult population 1,3. The diagnostic value of ultrasonography and color Doppler combined with fine needle aspiration FNA cytology for the detection of non-palpable axillary lymph node metastases in breast cancer patients has a high sensitivity and specificity when there are suspicious features.
