An unusual morphologic evolution of Paget's disease of bone
Abstract:
A patient with early Paget's disease of bone was treated for 12 months with calcitonin and 10 months with etidronate. During this time the cortex of each diseased bone showed a progressive 2- to 3-fold increase in thickness. Lytic areas regressed and the new bone appeared radiographically very compact. No bowing deformity developed in 3 years of observation. This form of morphologic evolution differs markedly from those previously reported during treatment. For this patient, treatment was instituted very early during the course of the disease and moderately high doses of vitamin D were given during part of the treatment course. Observation of a larger number of patients will be needed to determine whether these factors actually modified the treatment outcome.

Bone Remodeling
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Osteoclasts in Bone Remodeling
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
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...
