Haemangioma in an axillary lymph node
Screener. Grade 2 invasive carcinoma. This is one of the axillary sentinel nodes.
This is a good example of a large capillary haemangioma occupying much of the axillary lymph node. It could be mistaken for a metastatic deposit on imaging. It is of no clinical significance.
- A systematic review* of over 1000 axillary lymph nodes from 250 patients
from a busy breast unit showed nodal haemangiomas in only two. It was
suggested that there was an association with local malignancy. A more
common condition is more generalised nodal vascular dilatation which
affects all lymph nodes in a group whereas the haemangioma
(or haemangiomatoid as it is sometimes known) involves a single node.
