Zygomycosis encompasses infections due to two distinct orders of fungi, Mucorales and Entomophthorales. With rare exception, Entomophthorales are restricted to tropical areas. By contrast, mucorales are ubiquitous opportunistic fungi, which play a crucial part in the natural decay process. In human pathology, they may be opportunistic agents and be responsible for rare infection called (Mucormycosis) zygomycosis. We report two cases of zygomycosis from Madhya Pradesh, Central India, one caused by Rhizopus oryzae in a diabetic patient and another caused by Rhizopus microsporus in an apparently healthy patient. The cases were diagnosed by direct microscopy, histopathological examination and culture. Both the patients were successfully treated with liposomal amphotericin B. Rhizopus microsporus is, for the first time reported from Madhya Pradesh, India, causing rhino-maxillary orbital zygomycosis.

A 54-year-old man who had been on the kidney donor register for 32 years received a kidney from a 9-year-old boy who had died of fulminant myocarditis. The post-operative course was poor, and hemodialysis was still needed after surgery. A kidney biopsy one hour after surgery showed a neutrophil-predominant inflammatory cell infiltrate localized to the peritubular capillaries (PTC) and acute tubular necrosis of the proximal tubule.

The incidence and prevalence of mucormycosis reached an all-time high during the COVID-19 pandemic due to excessive steroid use and other factors, leading to the coining of the term CAM (COVID Associated Mucormycosis). The diagnosis of mucormycosis is by a combination of histopathology and microbiological techniques, such as KOH mount and culture.

Background: Mucormycosis, is a rare yet potentially life-threatening fungal infection common in immunocompromised patients. Despite optimal care, mucormycosis in haemato-oncological patients often results in poor outcomes. This case series details the presentations and unique challenges faced during the management of patients with acute myeloid leukemia who developed rhino-cerebral mucormycosis.

Purpose: The primary objective was to evaluate the clinical response of refractory cases of fungal keratitis to topical 1% posaconazole therapy.
Methods: Prospective longitudinal non-randomized open label dual-cohort study of 70 eyes of refractory fungal keratitis, 35 were recruited as posaconazole treatment (PCZ) group for topical 1% posaconazole therapy and compared to 35 eyes on conventional antifungal therapy. Study parameters included demographic and treatment details, visual acuity, comprehensive slit-lamp biomicroscopy, clinical photography, ASOCT at recruitment and weekly (week 1, 2, 3 and 4 after treatment initiation).
