Case in brief
A 51-year-old male presented with pneumothorax, leading to the diagnosis of sporadic lymphangioleiomyomatosis (LAM). High-resolution CT scans revealed multiple thin-walled cysts in both lungs. The diagnosis was supported by a history of renal angiomyolipoma and histopathologic findings, including positive immunohistochemical staining for HMB-45 and α-smooth muscle actin. The case highlights the need for accurate diagnosis and management.
Diagnostic / clinical pearl
Clinicians should consider sporadic lymphangioleiomyomatosis in the differential diagnosis of cystic lung disease in men, despite its rarity.
Why it matters
This case emphasizes the importance of early radiologic recognition and histopathologic confirmation for effective management of LAM.
