A 42-year-old woman undergoes appendectomy for acute appendicitis. Her postoperative course is complicated by wound erythema and edema on postoperative day 5. Vital signs show HR 88 bpm, BP 128/76 mmHg, temp 37.2°C. The incision site appears pink and soft without purulent drainage. Wound culture remains negative. Microscopy demonstrates proliferating capillaries, fibroblasts, and loose extracellular matrix with minimal collagen deposition. Which tissue type best describes these histologic findings?
- A)Dysplastic epithelium with loss of maturation
- B)Granulation tissue rich in type III collagen and new blood vesselsGABARITO
- C)Caseous necrosis with acellular cheese like debris
- D)Keloid tissue with disorganized type I collagen extending beyond the wound margins
- E)Fibrinoid necrosis due to plasma protein leakage into vessel walls

Granulation tissue is the hallmark of early wound healing and consists of newly formed capillaries, proliferating fibroblasts, inflammatory cells, and loose extracellular matrix rich in type III collagen. Around day 3 to 5 after surgery this pink granular tiss... Ver explicação completa e trilha adaptativa →
