Staining: HE

Organ: Lymph node

Description:

It’s obvious that this is a lymph node, however the normal architecture is absent. The lymph node is filled by the tumor cells, which have destroyed the normal structure of the lymph node. The tumor cells themselves show only mild atypia/pleiomorphism. They resemble centrocytes and are therefore centrocytic or centrocytoid.

Diagnosis: Chronic lymphocytic leukaemia

Causes:

  • Not well known

Theory:

The most frequent adult leukaemia.

Overview. No follicles, no cortex, no medulla, no sinuses.
Nice-looking cells.
