A squamous cell lung carcinoma with abscess-like distant metastasis

Area of Science:

• Oncology
• Pathology

Background:

• Squamous cell lung carcinoma is a common malignancy.
• Metastatic patterns can vary, but abscess formation is unusual.

Observation:

• A 55-year-old male presented with symptoms suggestive of infection, including fever, cough, hemoptysis, night sweats, chest and abdominal pain, and weight loss.
• Multiple abscess-like lesions rapidly developed in the lungs, liver, lymph nodes, bone, and subcutaneous tissue.
• Initial antimicrobial treatment was unsuccessful, and microbiological studies were negative.

Findings:

• Histopathological examination of abscess walls revealed metastatic squamous cell carcinoma.
• The lesions mimicked infectious abscesses, leading to a diagnostic challenge.

Implications:

• This case underscores the critical role of histopathology in diagnosing metastatic disease that presents atypically.
• It highlights the potential for squamous cell lung carcinoma to exhibit rapid, widespread metastasis with an unusual presentation mimicking infection.
