Histopathological Spectrum of Oral Mucormycosis: A Comprehensive Review

Oral mucormycosis, a life-threatening opportunistic fungal infection caused by Mucorales species, frequently involves the oral cavity as an extension of rhinocerebral disease, particularly in immunocompromised patients. This review elucidates its histopathologic hallmarks—broad, aseptate hyphae with right-angle branching, angioinvasion, and pauciseptate morphology, distinguishing it from mimics like aspergillosis. Amid rising incidence post-COVID-19, especially in diabetics, histopathology remains the gold standard for diagnosis, guiding aggressive debridement and amphotericin B therapy to improve survival from
