Case 292

Surgical Pathology Case


CLINICAL INFORMATION
	A 75-year-old male with significant past medical history of chronic obstructive pulmonary disease, coronary artery disease, benign prostatic hypertrophy, hyperlipidemia, splenomegaly, lymphadenopathies, anemia, and exposure to asbestos. Recently he developed symptoms of worsening sharp abdominal pain, right-sided and severe. CMPs, amylase-lipase, and electrolytes were all normal. CT scan revealed bilateral pulmonary masses, diffuse bilateral nodular pleural thickening, mediastinal hilar lymphadenopathy, mass lesions in the liver, possible T11 vertebral body involvement, and splenomegaly. A liver biopsy showed prominent necrosis with histiocytic reaction. Few atypical cells were noted, but immunostains failed to prove the natures of these cells. Therefore, a systemic metastatic tumor is highly suspicious, but an infectious process cannot totally be ruled out.
