Cells seen in MI at 48 hours are: (A) polymorphs, (B) Fibroblasts, (C) Lymphocytes, (D) Macrophages
Answer is A. The microscopic appearance also undergoes a characteristic sequence of changes . Typical features of coagulative necrosis become detectable within 4 to 12 hours of infarction. "Wavy fibers" also can be present at the edges of an infarct. Light microscopic features in 1-3 days include: Coagulation necrosis with loss of nuclei and striations; interstitial infiltrate of neutrophils. (Robbins basic pathology,9th edition.pg no.380)
