We report a rare case of sarcoidosis-lymphoma syndrome with vertebral bone destruction. A 63-year-old woman was previously diagnosed as sarcoidosis by supraclavicular lymph node biopsy, and came to our hospital complaining of back pain. Both serum angiotensin-converting enzyme and lysozyme level had been continuously elevated. Magnetic resonance imaging revealed lumbar vertebral bone destruction. Histopathologic examination of lumbar vertebral tumor obtained by CT-guided biopsy revealed non-caseating epithelioid granuloma with CD 68 (+), AE1/AE3 (-), and no malignant cells. She was admitted to our hospital again for dyspnea and pancytopenia. We diagnosed active sarcoidosis and administered oral 30mg prednisolone daily. One month later, prednisolone became ineffective. Flow cytometry of tumor cells obtained from the gastric ulcer floor showed CD 5 (+), CD 20 (+), K chain monoclonality and we diagnosed B-cell non Hodgkin's lymphoma. She was treated by eight cycles of CHOP plus rituximab chemotherapy and achieved complete response. FDG uptake of the entire body decreased, whereas MRI revealed residual mass in the vertebrae. Sarcoidosis had been diagnosed for two and half years before lymphoma developed. Bone destruction is very rare and sarcoidosis is rarely the cause. This is quite an unusual case presenting histologically proved epithelioid granuloma and vertebral destruction in sarcoidosis-lymphoma syndrome.
