Abstract

Many opportunistic infections occur in febrile neutropenic patients after chemotherapy. When lung masses are found in febrile neutropenic patients the first things that come to mind are tumor metastasis and yeast infections. Lung abscess that presents with the appearance of a mass is a very rare situation.

This paper presents a febrile neutropenic patient with an abscess caused by ESBL (-) E.coli with mass appearance similar to fungal ball and tumor metastasis. After antimicrobial treatment and 52 days after surgical intervention the patient was discharged.

We wish to draw attention to the fact that in patients with lung mass lesions and febrile neutropenia, fungal balls, tumor metastasis and abscesses have a similar appearance in the early period.
