title: Sarcoidosis and agnogenic myeloid metaplasia.
abstract: Agnogenic myeloid metaplasia (AMM) was recognized 3 years after a diagnosis of sarcoidosis in a 45-year-old man. This is the second reported instance of that association, and the 15th reported case in which systemic granulomata have been associated with a myeloproliferative disorder (MPD). In the client population at risk, this connection would be expected to occur by chance once in 1700 years. Therefore, it is unlikely that the association is fortuitous. Systemic granulomata may represent an immunologic response to antigens of neoplastic origin in MPD.
