This 'hairy' lymphocyte comes from a person suffering from an active infection (without any malignant disease). The granula identify it as a T or an NK cell.

Reticulocyte staining. Characteristic HbH cell in a case of α-thalassaemia. Today, blood films are no longer investigated for HbH cells. Instead,
α-thalassaemias are diagnosed by molecular genetic tests.

A remarkably high and conspicuous number of megakaryocytes (->) is visible in the bone marrow histology (Giemsa stain) of a patient with CML.

Bone marrow histology (Giemsa stain) showing two Hodgkin cells (H). These giant cells have an oval, non-lobulated nucleus and at least one nucleolus. Reed-Sternberg cells (RS) have a lobulated nucleus with several nucleoli. Both cell types are characteristic of Hodgkin's disease and express the same surface marker CD30, which is otherwise found on activated lymphocytes.

Bone marrow histology (Giemsa stain) of a patient showing an infiltrating Hodgkin's lymphoma on the left side. On the right side normal haematopoietic tissue can be seen.

Howell-Jolly bodies in the cell adjacent to the granulocyte, spherocytes, polychromasia, and a single erythroblast in a case of auto-immune haemolytic anaemia (AIHA). (Howell-Jolly bodies are DNA remnants. Polychromatic cells still contain RNA.)

An apparent Howell-Jolly body, caused by contaminated microscope oil, can be identified as an artefact by the fact that it moves independently over time.

Round residual nucleus of purple-brown colour, circular, not refactive, eccentrically placed, frequently associated with acanthocytes, target cells or Pappenheimer bodies. Incidence: post splenectomy, severe anaemia with intact spleen function, e.g. pernicious anaemia, MDS
