Abstract:
We treated a 78-year-old Japanese man with gastric diffuse large B cell lymphoma. The patient received three courses of chemotherapy and involved-field local radiation therapy to the stomach. Three years after chemotherapy, the patient become sick with anorexia and pancytopenia. He was cachexic, however, levels of vitamin B12, folate, zinc, and copper were normal. His bone marrow revealed focal eosinophilic deposit characterized by mixture of vivid atrophic fatty cells, which was pathologically diagnosed as gelatinous bone marrow. The patient's gelatinous marrow was characterized by CD68-stained vivid atrophic fatty tissue. We found that this finding is a possible alternative marker for gelatinous marrow.

Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts—...
Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
