Howell-Jolly body – Wikipedia
A Howell-Jolly body is a cytopathological finding of basophilic nuclear remnants in circulating erythrocytes. During maturation in the bone marrow, late erythroblasts normally expel their nuclei; but, in some cases, a small portion of DNA remains. Its presence usually signifies a damaged or absent spleen, because a healthy spleen would normally filter this type of red blood cell. The Howell-Jolly body is named after William Henry Howell and Justin Marie Jolly.

What is the Howell-Jolly body? – Stanford Medicine 25
His thesis was on the origin of fibrin in blood coagulation. During his work on coagulation, Howell began to observe how granules stained like nuclei. He went on to describe larger granules that would later be described as Howell’s nuclear particles. (7) Justin Marie Jolly was born in 1870 in Melun, now a Paris suburb, obtaining his doctorate in 1898 at the University of Paris. During his work, Jolly refined and detailed many of Howell’s descriptions. He described …

Howell-Jolly bodies are nuclear remnants found in red blood cells (erythrocytes) under various pathological states. They most commonly present in patients with absent or impaired function of the spleen; this is because one of the spleen’s functions is to filter deranged blood cells and remove the intracellular inclusions left by the erythrocyte precursors. William Howell and Justin Jolly in the early 1900s first discovered Howell-Jolly bodies in the early 1900s.[1]

62 In what conditions are Howell-Jolly bodies found? Howell-Jolly bodies are nuclear remnants that are found in the RBCs of patients with reduced or absent splenic function (e.g., sickle cell disease, heterotaxy) and in patients with megaloblastic anemias. They are occasionally present in the RBCs of premature infants. These remnants are part of the process of normal RBC maturation but are typically removed by a normal spleen. Howell-Jolly bodies are dense, dark, and perfectly round, and …

What are Howell-Jolly Bodies? Howell-Jolly bodies are round, smooth, almost pyknotic, dark purple bodies ranging in size from 0.5 to 1.0 micron in diameter. Located eccentrically, usually only one Howell-Jolly body occurs in a mature or nucleated erythrocyte. Occasionally, two or more Howell-Jolly bodies per cell may be found.

A Howell-Jolly body is a cytopathological finding of basophilic nuclear remnants (clusters of DNA) in circulating erythrocytes. During maturation in the bone marrow, late erythroblasts normally expel their nuclei; but, in some cases, a small portion of DNA remains. What are Howell-Jolly bodies composed of? These RBC inclusions contain DNA.

Howell jolly bodies. Inclusions within red blood cells composed of denatured hemoglobin. They are formed as a result of oxidative damage or mutations (i.e G6PD) Macrophages in the spleen remove the denatured hemoglobin giving rise to the classic bite cells (see below) Nuclear (basophilic) inclusions within RBCs.
