Unusual association of orbital tumour and rhino-orbital-cerebral mucormycosis.

In developing tropical countries, rhino-orbital-cerebral mucormycosis has been a cause of severe morbidity and mortality during the COVID-19 pandemic. Classically, it develops as an aggressive angioinvasive destruction of nasal, orbital and cerebral involvement. Blindness is a major disabling complication. The association of mucor in cancer is linked with immunosuppression caused by radiation and/or chemotherapy. In this case report, we tried to explore the diverse possibilities of neck swelling, nasal discharge, ocular swelling and dimness of vision in a teenage boy. Rhabdomyosarcoma is a rare tumour of the soft tissue, connective tissue or bone. This type of unusual association or coexistence of rhabdomyosarcoma with mucormycetes is rarely seen in literature.
