title: [Crow-Fukase syndrome (POEMS syndrome) and osseous mastocytosis secondary to Castleman's angiofollicular lymphoid hyperplasia].
abstract: In a case of Crow-Fukase (POEMS) syndrome there was a chronic, progressive, and eventually lethal polyradiculoneuropathy. In addition, adenomegaly, oedema and pleural effusions, gonadic atrophy, serum monoclonal IgA, and skin pigmentation were present. Plain x-rays and CT scan of the pelvis and lower vertebrae showed multiple poorly defined lesions. At postmortem there was no myeloma and a bone mastocytosis was found. In addition, next to T11, there was an abdominal nodule, 2 cm in diameter, with histological characteristics of Castleman's angiofollicular lymphoid hyperplasia. Immunohistochemical studies showed that plasmocytes of this lesion secreted polyclonal immunoglobulins with a high prevalence of IgA. Thus, the primary interest of this case lies in the association of bone mastocytosis with a POEMS syndrome. Also, one single localisation of Castleman angiofollicular lymphoid hyperplasia was found, assumed to be in this case the cause of the POEMS syndrome. Therefore, a minute and benign hyperplasic lesion, which was only discovered at autopsy, secreted the protein responsible for the symptoms and signs, and eventually the patient's death.
