(B) Wall of blood vessel is invaded by broad irregular fungal hyphae of Mucor confirming angioinvasion. (C) Gomori Methenamine Silver (GMS) (400x) stain highlighting the fungal hyphae. (D) KOH mount (400x) showing broad hyaline pauciseptate hyphae with right angled branching suggestive of mucormycosis.
