# Co-Existing Fungi: An Unforeseen Combo Creating a Dilemma in Diagnostic Morale

## TL;DR

This paper discusses a rare case where a patient had both mucormycosis and aspergillus infections, leading to a misdiagnosis.

## Contribution

The novelty lies in reporting a co-infection of mucormycosis and aspergillus in an immunocompromised cancer patient.

## Key findings

- The patient was initially misdiagnosed with aspergillus infection.
- Pulmonary mucormycosis was later identified alongside aspergillus.
- The case highlights diagnostic challenges in immunocompromised individuals.

## Abstract

Mucormycosis is a rare fungal infection belonging to Mucorales order fungi. Rhino-cerebral form is more noted in patients with diabetes mellitus, but pulmonary mucormycosis is a rare manifestation with hematological malignancy, malignant tumors, and transplant recipient patients. Aspergillus species are also known to cause allergic bronchopulmonary aspergillosis, aspergilloma, chronic pulmonary aspergillosis, and invasive aspergillosis in immunocompromised individuals. We report a case of pulmonary mucormycosis superimposed with aspergillus infection presenting in an immunocompromised patient with metastatic prostate cancer on chemotherapy, initially misdiagnosed as aspergillus infection.
