A 65-year-old @entity1 with @entity370 , accompanied by muscle nodules, noticed a painless and enlarged nodule in his forearm. MRI of the nodule showed that a star-shaped area of lower signal intensity was surrounded by an area of higher signal intensity. Histological examination showed @entity738 composed of @entity4843 cells and epithelioid cells. @entity370 was diagnosed. Eight months later, he was admitted to our hospital because of enlargement of the nodular region with @entity158 and @entity2693 . Marked uptake of 67Ga was observed in the right arm and leg. MRI revealed sarcoid nodules in these regions. An enlargement of the higher signal intensity area was observed in the right forearm nodule. We started administration of @entity617 . Forty days later, his symptoms had disappeared and the size of higher signal intensity area of the nodule had reduced dramatically. 67Ga scintigram and MRI were useful for diagnosis and monitoring during therapy in this @entity1 .
