Gandy–Gamna nodules

Gandy–Gamna nodules or Gandy-Gamna bodies, sometimes known as Gamna-Gandy bodies or Gamna-Gandy nodules, are small yellow-brown, brown, or rust-colored foci found in the spleen in patients with splenomegaly due to portal hypertension,[1] as well as sickle cell disease. They consist of fibrous tissue with haemosiderin and calcium deposits, and probably form due to scarring at sites of small perivascular haemorrhages.[2] They are visible on MRI scanning due to the presence of haemosiderin.[3]

Micrograph of the spleen showing darkly stained, spheroid Gamna-Gandy bodies (arrows) outside the vessel wall at the center. Also shown is diffusely scattered, brown, granular hemosiderin pigment (arrowheads), indicating previous hemorrhage (hematoxylin & eosin staining, 40x magnification).
Gandy–Gamna nodules may also be seen in chronic pulmonary congestion.

They can also be seen in atrial myxomas.

They are named after Charles Gandy and Carlos Gamna.
