Gandy–Gamna nodules

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.

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]

They can also be seen in atrial myxomas.

They are named after Charles Gandy and Carlos Gamna.
