    Area of Science:

    • Pulmonology
    • Oncology
    • Radiology

    Background:

    • Bleomycin is a chemotherapy agent used to treat various cancers, including squamous epitheliomas.
    • Pulmonary toxicity is a known, albeit infrequent, side effect of Bleomycin therapy.
    • Early identification of Bleomycin-induced lung injury is crucial for patient management.

    Purpose of the Study:

    • To investigate the incidence and characteristics of pulmonary fibrosis in patients treated with Bleomycin for squamous epitheliomas.
    • To correlate radiological findings with pathological changes observed in lung biopsies.
    • To discuss diagnostic challenges associated with these radiological findings.

    Main Methods:

    • Retrospective analysis of 25 patients treated with Bleomycin for squamous epitheliomas.
    • Review of radiological imaging (chest X-rays/CT scans) for evidence of interstitial changes.
    • Correlation of imaging findings with histopathological results from lung biopsies.
    • Clinical assessment of fibrosis reversibility.

    Main Results:

    • Six out of 25 patients developed pulmonary fibrosis (four irreversible, two reversible).
    • Radiological findings included linear interstitial shadows (five patients) and nodular shadowing (one patient).
    • Lung biopsies confirmed the pathological basis for the observed radiological changes.

    Conclusions:

    • Bleomycin can induce significant pulmonary fibrosis in a subset of patients with squamous epitheliomas.
    • Characteristic radiological patterns are associated with Bleomycin-induced lung injury.
    • Differential diagnosis of these findings requires careful consideration of treatment history and pathological correlation.
