Axillary lymphadenopathy is distinguished by an increase in volume or changes in the morphology of the axillary lymph nodes. It can be detected through palpation during a physical examination or through changes in imaging tests. On a mammogram (MMG), normal lymph nodes typically appear oval or reniform with a radiolucent center representing ...
A lymph node is small, capsulated lymphoid organ that is present along the lymphatic system. It is composed of cortex and medulla. The cortex is also divided into outer cortex and inner cortex (also known as the paracortex). The outer cortex is composed of follicles of B cells so that it is called the B-cell zone.
However, inguinal lymph nodes of up to 15 mm and cervical lymph nodes of up to 20 mm are generally normal in children up to age 8–12. [ 38 ] Lymphadenopathy of more than 1.5–2 cm increases the risk of cancer or granulomatous disease as the cause rather than only inflammation or infection .
This typically occurs in the cortex without disrupting the lymph node capsule. [1] The follicles are pathologically polymorphous , are often contrasting and varying in size and shape. [ 2 ] Follicular hyperplasia is distinguished from follicular lymphoma in its polyclonality and lack of bcl-2 protein expression, whereas follicular lymphoma is ...
A lymph node is divided into compartments called nodules (or lobules), each consisting of a region of cortex with combined follicle B cells, a paracortex of T cells, and a part of the nodule in the medulla. [17] The substance of a lymph node is divided into the outer cortex and the inner medulla. [4]
There are many factors to consider when diagnosing a malignant lump. Trouble swallowing or speaking, swollen cervical lymph nodes or a firm, immobile nodule are more indicative of malignancy, whereas a family history of autoimmune disease or goiter, thyroid hormonal dysfunction or a soft, painful nodule are more indicative of benignancy.

Ultrasound examination is usually adequate in evaluating primary tumours and cervical lymph nodes. Preoperative cross-sectional imaging with CT or MRI is indicated if there is a concern for local invasion that may alter the patient's staging as well as surgical approach (Figs. 4, 55 and 6)6) .
