Giant thoracic mass: an unusual presentation of primary pulmonary Hodgkin's lymphoma

SUMMARY Primary pulmonary Hodgkin’s lymphoma (PPHL) is rare. PPHL without peripheral lymphadenopathy or hepatosplenomegaly is exceptionally uncommon. We present a 61-year-old woman believed to have a solitary intrapulmonary fibrous tumour on a CT and a CT-guided biopsy, until surgical excision. Histopathology and immunohistochemistry of the excised mass confirmed PPHL. PPHL is a very rare differential diagnosis of large solitary intrapulmonary masses. A CT-guided biopsy is recommended, as it can be diagnostic, reserving excision for cases where the diagnosis remains in doubt.
