Objective:
The purpose of this study was to review the sonographic findings of various axillary masses other than lymph nodes in correlation with other imaging and pathologic findings.
Methods:
From a sonographic database, we collected interesting cases of axillary masses with pathologic or other imaging corroboration from the last 10 years.
Results:
Images of various soft tissue masses were reviewed. They included masses associated with accessory breasts (fibroadenomas, hamartomas, fat necrosis, and cancer arising from axillary breasts), other soft tissue masses (lipomas, schwannomas, hemangiomas, fibromatosis, epidermoid cysts, and malignant fibrous histiocytomas), and complications presenting as masses after axillary lymph node dissection (seromas, hematomas, suture granulomas, pseudoaneurysms, and lymphangiectasia).
Conclusions:
Awareness of the characteristic sonographic findings of various disease entities that cause axillary masses will help in the correct diagnosis of axillary masses.

Assessing Body Temperature - Axilla
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
