Castleman's disease is a rare lymphoproliferative disorder.
Hyaline vascular Castleman's disease is the most common subtype.
Pleural involvement is uncommon.
Observation:
A 71-year-old male presented with a Castleman's pseudotumor (hyaline vascular type) in the left pleural cavity.
The pseudotumor was located above the apex of the left lung.
The patient had a history of postprimary pulmonary tuberculosis with tuberculous empyema and hematogenous dissemination.
Findings:
Histopathological examination confirmed the diagnosis of hyaline vascular Castleman's pseudotumor.
The pseudotumor's development was associated with underlying postprimary pulmonary tuberculosis.
Evidence of tuberculous empyema and hematogenous dissemination was noted.
Implications:
This case highlights an unusual presentation of Castleman's disease.
It underscores the importance of considering Castleman's disease in the differential diagnosis of pleural masses, especially in patients with a history of tuberculosis.
Management requires a multidisciplinary approach involving thoracic surgery, pulmonology, and pathology.
