Aspergillosis: An Unwanted Tenant of Lung Cavity in an Immunocompromised Host.

Immunocompromised status predisposes an individual to infection from bacteria, fungi, and viruses that are otherwise uncommon. The presence of carcinoma and the use of chemotherapy weakens one's immune system and leads to opportunistic infections of many kinds. Aspergilloma is a fungal ball that grows inside a primary cavitary lesion within the pulmonary parenchyma. Generally, immunocompromised individuals have severe and invasive infections from Aspergillus. Here, we present a case report of a female with breast carcinoma undergoing chemotherapy who previously had a lung abscess with Klebsiella. During her subsequent presentation, she was detected to have aspergilloma along with multi-drug-resistant organisms in the lung abscess along with metastasis of breast carcinoma and lung squamous cell carcinoma encapsulating the fungal ball.
