Necrobiosis

Necrobiotic disorders are characterized by presence of necrobiotic granuloma on histopathology. Necrobiotic granuloma is described as aggregation of histiocytes around a central area of altered collagen and elastic fibers. Such a granuloma is typically arranged in a palisaded pattern.[2]
It is associated with necrobiosis lipoidica and granuloma annulare.
Necrobiosis differs from apoptosis, which kills a damaged cell to protect the body from harm.
