Dispenzieri A. POEMS syndrome: Update on diagnosis, risk-stratification, and management. Am J Hematol 2023; 98:1934-1950.

Abstract
DISEASE OVERVIEW POEMS syndrome is a life-threatening condition due to an underlying plasma cell neoplasm. The major criteria for the syndrome are polyradiculoneuropathy, clonal plasma cell disorder, sclerotic bone lesions, elevated vascular endothelial growth factor, and the presence of Castleman disease. Minor features include organomegaly, endocrinopathy, characteristic skin changes, papilledema, extravascular volume overload, and thrombocytosis. DIAGNOSIS The diagnosis of POEMS syndrome is made with three of the major criteria, two of which must include polyradiculoneuropathy and clonal plasma cell disorder, and at least one of the minor criteria. RISK STRATIFICATION Because the pathogenesis of the syndrome is not well understood, risk stratification is limited to clinical phenotype rather than specific molecular markers. Risk factors include low serum albumin, age, pleural effusion, pulmonary hypertension, and reduced estimated glomerular filtration rate. RISK-ADAPTED THERAPY For those patients with a dominant plasmacytoma, first-line therapy is irradiation. Patients with diffuse sclerotic lesions or disseminated bone marrow involvement should receive systemic therapy. Corticosteroids are temporizing, but alkylators and lenalidomide are the mainstays of treatment, the former either in the form of low-dose conventional therapy or as high-dose conditioning for stem cell transplantation. Thalidomide and bortezomib also have activity, but their benefit needs to be weighed against their risk of exacerbating the peripheral neuropathy. Daratumumab combinations also appear promising based on case series. Prompt recognition and institution of both supportive care measures and therapy directed against the plasma cell result in the best outcomes.

Abstract
DISEASE OVERVIEW POEMS syndrome is a paraneoplastic syndrome due to an underlying plasma cell neoplasm. The major criteria for the syndrome are polyradiculoneuropathy, clonal plasma cell disorder (PCD), sclerotic bone lesions, elevated vascular endothelial growth factor, and the presence of Castleman disease. Minor features include organomegaly, endocrinopathy, characteristic skin changes, papilledema, extravascular volume overload, and thrombocytosis. DIAGNOSIS The diagnosis of POEMS syndrome is made with three of the major criteria, two of which must include polyradiculoneuropathy and clonal plasma cell disorder, and at least one of the minor criteria. RISK STRATIFICATION Because the pathogenesis of the syndrome is not well understood, risk stratification is limited to clinical phenotype rather than specific molecular markers. Risk factors include low serum albumin, age, pleural effusion, pulmonary hypertension, and reduced eGFR. RISK-ADAPTED THERAPY For those patients with a dominant plasmacytoma, first line therapy is irradiation. Patients with diffuse sclerotic lesions or disseminated bone marrow involvement and for those who have progression of their disease 3-6 months after completing radiation therapy should receive systemic therapy. Corticosteroids are temporizing, but alkylators are the mainstay of treatment, either in the form of low dose conventional therapy or high dose with stem cell transplantation. Lenalidomide shows promise with manageable toxicity. Thalidomide and bortezomib also have activity, but their benefit needs to be weighed against their risk of exacerbating the peripheral neuropathy. Prompt recognition and institution of both supportive care measures and therapy directed against the plasma cell result in the best outcomes.

Abstract
Castleman's disease (CD) is a rare, poorly understood lymphoproliferative disease. The spectrum of symptoms and course of disease are broad, but there is no large study describing the natural history of this disease. Basic clinic and laboratory data from the records of 113 patients with CD evaluated at the Mayo Clinic and University of Nebraska were abstracted. The impact of these variables on overall survival (OS) from time of diagnosis was evaluated. Sixty patients had multicentric disease. Of the patients with multicentric CD, 32% had criteria sufficient for a diagnosis of POEMS syndrome. For all patients, 2, 5, and 10-year OS was 92%, 76%, 59%, respectively. Most of the factors identified as risk factors for death on univariate analysis cosegregated with diagnostic criteria for POEMS syndrome, which supported the concept of four categories of CD, which are (along with their 5-year OS): (1) unicentric CD (91%); (2) multicentric CD associated with the osteosclerotic variant of POEMS syndrome (90%); (3); multicentric CD without POEMS syndrome (65%); and (4) multicentric CD with POEMS syndrome without osteosclerotic lesions (27%). We have demonstrated that CD represents a spectrum of disease that can be differentiated by simple prognostic factors that provide a framework for further study.

Abstract
POEMS syndrome is a rare paraneoplastic syndrome secondary to a plasma cell dyscrasia. Recognition of the complex of a combination of peripheral neuropathy, organomegaly, endocrinopathy, monoclonal plasmaproliferative disorder, skin changes, papilledema, extravascular volume overload (peripheral edema, pleural effusions, ascites), sclerotic bone lesions, thrombocytosis, Castleman disease is the first step in effectively managing the disease. A rise in the blood levels of vascular endothelial growth factor is usually confirmatory. More than 95% of patients will have monoclonal lambda sclerotic plasmacytoma(s) or bone marrow infiltration. In patients with a dominant sclerotic plasmacytoma, first line therapy should include radiation to the lesion. Retrospective analysis and personal experience would dictate that systemic therapy be considered for patients with diffuse sclerotic lesions or absence of any bone lesion and for those who have not demonstrated stabilization of their disease 3 to 6 months after completing radiation therapy. For those patients with diffuse disease, systemic therapy is indicated. Useful approaches include therapy with corticosteroids, low dose alkylator therapy, and high dose chemotherapy with peripheral blood stem cell transplant. Until the pathogenesis is fully understood, these are the mainstays of treatment for patients with POEMS syndrome. The role of anti-VEGF therapies, immune modulatory drugs, and proteasome inhibitors has not yet been defined, but drugs with known high rates of treatment related neuropathy should not be considered as first line therapy.

Abstract
Peripheral neuropathy is usually the presenting feature of POEMS syndrome. Approximately 50% of patients with POEMS syndrome are associated with osteosclerotic myeloma, a rare variant of multiple myeloma, and some with Castleman's disease, an unusual lymphoproliferative disorder. The multicentric plasma cell variant of Castleman's disease is usually associated with systemic disorders rather than its localized form of mediastinal lymphoid hyperplasia characterized by hyalinization of follicles and interfollicular vascular proliferation. We report a 48-year-old woman who presented with progressive sensorimotor demyelinating polyradiculoneuropathy, bilateral optic disc edema, hepatosplenomegaly, generalized lymphadenopathy, and skin changes. There was associated thrombocytosis, hypothyroidism, hypoparathyroidism, mixed osteolytic and osteosclerotic bone lesions, monoclonal gammopathy of IgG lambda type, and hyaline vascular type of Castleman's disease. This combination of POEMS syndrome, osteosclerotic myeloma with a hyaline vascular type of Castleman's disease is uncommon.

Abstract
Recent efforts to identify treatments for chronic diabetic complications have resulted in the discovery of a novel series of highly potent and selective 3-[(benzothiazol-2-yl)methyl]indole-N-alkanoic acid aldose reductase inhibitors. The lead candidate, 3-[(4,5,7-trifluorobenzothiazol-2-yl)methyl]indole-N-acetic acid (lidorestat, 9) inhibits aldose reductase with an IC(50) of 5 nM, while being 5400 times less active against aldehyde reductase, a related enzyme involved in the detoxification of reactive aldehydes. It lowers nerve and lens sorbitol levels with ED(50)'s of 1.9 and 4.5 mg/kg/d po, respectively, in the 5-day STZ-induced diabetic rat model. In a 3-month diabetic intervention model (1 month of diabetes followed by 2 months of drug treatment at 5 mg/kg/d po), it normalizes polyols and reduces the motor nerve conduction velocity deficit by 59% relative to diabetic controls. It has a favorable pharmacokinetic profile (F, 82%; t(1/2), 5.6 h; Vd, 0.694 L/kg) with good drug penetration in target tissues (C(max) in sciatic nerve and eye are 2.36 and 1.45 mug equiv/g, respectively, when dosed with [(14)C]lidorestat at 10 mg/kg po).

Abstract
The POEMS syndrome (coined to refer to polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes) remains poorly understood. Ambiguity exists over the features necessary to establish the diagnosis, treatment efficacy, and prognosis. We identified 99 patients with POEMS syndrome. Minimal criteria were a sensorimotor peripheral neuropathy and evidence of a monoclonal plasmaproliferative disorder. To distinguish POEMS from neuropathy associated with monoclonal gammopathy of undetermined significance, additional criteria were included: a bone lesion, Castleman disease, organomegaly (or lymphadenopathy), endocrinopathy, edema (peripheral edema, ascites, or effusions), and skin changes. The median age at presentation was 51 years; 63% were men. Median survival was 165 months. With the exception of fingernail clubbing (P =.03) and extravascular volume overload (P =.04), no presenting feature, including the number of presenting features, was predictive of survival. Response to therapy (P <.001) was predictive of survival. Pulmonary hypertension, renal failure, thrombotic events, and congestive heart failure were observed and appear to be part of the syndrome. In 18 patients (18%), new disease manifestations developed over time. More than 50% of patients had a response to radiation, and 22% to 50% had responses to prednisone and a combination of melphalan and prednisone, respectively. We conclude that the median survival of patients with POEMS syndrome is 165 months, independent of the number of syndrome features, bone lesions, or plasma cells at diagnosis. Additional features of the syndrome often develop, but the complications of classic multiple myeloma rarely develop.

Abstract
The pathogenic link between POEMS (polyneuropathy, organomegaly, endocrinopathy, M protein, skin changes, and various other clinical signs) syndrome and Castleman's disease is unclear. Roles for M protein in POEMS syndrome and cytokines in systemic manifestations of multicentric Castleman's disease have been suggested. Recently, pathogenic roles of cytokines in POEMS syndrome and Kaposi's sarcoma-associated herpesvirus (KSHV) in Castleman's disease have been reported. We report on a patient with KSHV-associated Castleman's disease with POEMS syndrome, and suggest a possible role of KSHV in initiating and linking these two diseases.

Other various clinical and biological features are reported: edema, cachexia, microangiopathic glomerulopathy, most rarely pulmonary hypertension, cutaneous necrosis. Thrombocytosis or polycythemia may be a prominent feature. POEMS syndrome is sometimes associated with lymphoproliferative disorder. Castelman-like disease is frequently observed as pathologic findings on lymph nodes. Distinction between POEMS syndrome and osteosclerotic myeloma is delicate. The rate of the monoclonal protein is modest-always less than 30 g/L-and is almost of the lambda light chain class. In contrast to multiple myeloma this syndrome is rarely associated with hypercalcemia, skeletal fracture, renal involvement and increasing of M component during evolution. Bone marrow plasmocytosis is usually less than 15% and the kinetic phenotype and genetic characteristics of the plasma cell remain those found in monoclonal gammopathy of undetermined significance. The pathophysiology of this syndrome remains largely unknown but overproduction of pro-inflammatory cytokines are reported, especially TNF alpha, IL-6 and IL-1 beta. Some clinical manifestations seem to be cytokine related. Polyneuropathy and cachexia are the main cause of death. A part corticosteroid and cure of solitary bone lesion, treatment is disappointing and survival is 60% at five years.

Abstract
The POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammapathy, and skin changes) syndrome is a rare variant of plasma cell dyscrasia with multisystemic manifestations. We present 4 cases with arterial symptoms typical of acute arterial obliteration (AAO) and review 9 similar cases in the literature. The clinical course of AAO was unusual and particularly severe when affecting the lower limbs; recurrent events required amputations. As demonstrated by angiographic and histologic studies, thrombotic and atheromatous lesions were the main pathologic features of AAO. Atherosclerotic risk factors were absent or moderate in 3 of our cases, and no cause of thrombosis other than the POEMS syndrome was found. A high production of cytokines was found in all cases, with elevated serum levels of interleukin-1 beta (9/9 samples), interleukin-6 (7/9 samples), and tumor necrosis factor-alpha (6/9 samples). We suggest that arterial manifestations should be added to the spectrum of manifestations of the POEMS syndrome. Cytokines may mediate the POEMS syndrome-associated AAO, as previously proposed for the other systemic manifestations of this disorder.

Abstract
Approximately 10% of patients with idiopathic peripheral neuropathy have an associated serum monoclonal gammopathy or M-protein. This represents six times the incidence of M-proteins found in the general population. In 5% of idiopathic peripheral neuropathy patients the M-protein is associated with an identifiable plasma cell dyscrasia. Sclerotic myeloma is particularly important to recognize because treatment may result in amelioration of the neuropathy and remission of the tumor. Patients with primary systemic amyloidosis often have preferential small fiber involvement with a dissociated sensory loss and autonomic dysfunction. The nerve root infiltration of lymphoproliferative disorders may simulate a polyradiculoneuropathy. In cases without an identifiable cause for the M-protein, referred to as monoclonal gammopathy of undetermined significance (MGUS), the pathophysiologic basis for the neuropathy is poorly defined in most cases. A role for M-proteins with antibody activity to myelin-associated glycoprotein is provocative. This review summarizes current knowledge of this important group of disorders.

Abstract
Castleman's disease is a rare clinicopathological entity characterized by multicentric angiofollicular lymph node hyperplasia. Peripheral neuropathy has infrequently been described in patients with Castleman's disease. A patient is described who presented initially with severe painful sensorimotor polyneuropathy of his lower limbs diagnosed as a plasma cell variant of Castleman's disease associated with features of POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M protein, and skin change). The patient was treated with plasmapheresis, immunosuppressive agents, and intensive rehabilitation. His functional status improved from being wheelchair bound to ambulating independently with crutches. Clinicians should be alert to the relationship of Castleman's disease and mixed polyneuropathy because physical improvement is possible with treatment. Also, the evaluation of patients presenting with peripheral neuropathy of unknown etiology and lymphadenopathy should include lymph node biopsy to rule out Castleman's disease.

Abstract
We report six patients affected by POEMS syndrome (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy, and Skin changes), a peculiar multiorgan disease frequently associated with osteosclerotic myeloma or other plasma cell disorders. Sensorimotor polyneuropathy was associated with multisystem involvement in all of the patients, with osteosclerotic myeloma in 2 cases, monoclonal gammopathy of undetermined significance in 2 cases and Castleman's disease in the final two. In all of the patients, sural nerve biopsy findings were consistent with a mixed, axonal and demyelinating neuropathy. Increased levels of Interleukin-6 were found in two cases, but the pathogenesis of the disease is far from established.

Abstract
Castleman disease, or angiofollicular lymph node hyperplasia, and POEMS (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy, and Skin changes), are associated and can lead to a clinical conundrum. The physician caring for a patient with Castleman disease should be alert to the development of multiple endocrine deficiencies, including primary hypogonadism, diabetes mellitus, hypothyroidism, and adrenal insufficiency. Avoidance of treating hypothyroidism alone when there is concomitant subclinical adrenal insufficiency is important, to avoid precipitating an adrenal crisis. A better outcome may result from earlier recognition of the endocrinopathies of this syndrome. This article describes a patient with Castleman disease in whom the features of POEMS unfolded over the ensuing years.

Abstract
Two patients with paraprotein-associated peripheral polyneuropathy were treated successfully using immunoadsorption of patient's plasma with staphylococcal protein A. Both had previously been treated with immunosuppressive agents or plasma exchange, and were rapidly relapsing at the time of their protein A immunoadsorption therapy. One patient was treated "on-line" with a blood cell separator, and one was treated "off-line." Both responded well to therapy with minimal toxicity. Serum levels of circulating immune complexes were elevated in one patient and remained so during and after therapy. Immunoadsorption with protein A should be investigated as a therapeutic option for patients with paraprotein-associated peripheral polyneuropathy. The therapy is relatively easy to administer, particularly "off-line," and was well tolerated by our patients. More experience, including formal clinical trials, will be required to properly define the indications for, and mechanism of response to, this therapy.

Abstract
A 27-year-old white man with no significant risk factors for coronary artery disease presented with a 9-month history of progressive impotence, gynecomastia, lower extremity paresthesias, and extensive myocardial infarction and subsequently developed ulcerative proctitis. A diagnosis of POEMS syndrome was made based on the clinical presentation; additional physical findings of papilledema, clubbing, and hyperpigmentation; and laboratory findings of an immunoglobulin G M component of the lambda subtype, elevated cerebrospinal fluid protein, and typical sclerotic bone lesions. Abnormal in vitro binding of the patient's serum immunoglobulin to testicular tissue was also seen. Cardiac catheterization showed evidence of diffuse coronary artery narrowing and left ventricular wall motion abnormalities. Diffuse coronary involvement and ulcerative proctitis have not been previously described in POEMS syndrome. It is hypothesized that an abnormal immunoglobin (or fragment) is responsible for both findings. Furthermore, the detection of antitesticular autoantibodies suggests the possibility of an interaction between the antibody and Leydig cells, leading to an alteration in the synthesis and release of sex steroids and thereby explaining the gonadal failure seen in this syndrome. Long-term glucocorticoid therapy for the past 5 years has resulted in marked subjective and objective improvement.

Abstract
The authors present the results of an autopsy of a 67-year-old Japanese man with POEMS/Takatsuki/Crow-Fukase syndrome (P/T/CFS) diagnosed in 1972. Each component of the syndrome was gradually recognized after the resection of lumbar vertebral solitary plasmacytoma in 1967. The patient died in 1989 of generalized infection and renal failure. Autopsy revealed in the vertebral canal between the fifth and seventh thoracic vertebrae dorsal pachymeningeal fibrosis, with prominent amyloid deposition that oppressed the spinal cord. This condition was consistent with the final neurologic manifestation of the patient, bilateral motor and sensory disturbance below the sixth thoracic level. Myelopathy remained clinically unnoticed because neurologic disturbance had begun as peripheral polyneuropathy. Normocellular marrow with heterogeneously scattered lambda light chain-positive plasma cells and degeneration of the myelinated fibers of sciatic nerve also were observed. This is the first report of focal spinal amyloidosis associated with P/T/CFS.

Abstract
POEMS syndrome is a rare multisystem affliction known for its signs, from which it also takes its acronym name "peripheral neuropathy, organomegaly, endocrinopathy, monoclonal (M) protein, and skin lesions." Our study chronicles the course of this syndrome in a young woman with Castleman's disease (angiofollicular lymph node hyperplasia). Cerebrospinal fluid (CSF) and serum interleukin-6 (IL-6) levels were abnormally elevated at various times during a 9-month period. The authors conclude that the plasma cell dyscrasia associated with the POEMS syndrome of this patient was Castleman's disease. Elevation of serum IL-6 levels might contribute to the pathogenesis of the POEMS syndrome.

Abstract
Recent progress in immunopathological studies of peripheral nerve and lymph node fragments together with 16 personal cases and numerous clinicopathological reports have suggested a new classification of peripheral neuropathies (PN) and lymphomas. These are: (1) PN due to local infiltrations by a T-cell lymphoma: (2) acute polyradiculoneuritis due to active demyelination and associated with infiltrates of a T-cell lymphoma in the epineurium, resembling Marek's disease (which is a T-cell lymphoma); (3) B-cell lymphoma proliferation which may be restricted to or predominate in the peripheral nervous system, with a large clinicopathological heterogeneity ranging from localized forms to ascending polyradiculoneuropathies; (4) angiotropic lymphoma, which is a B-cell lymphoma and may present as an acute mononeuropathy; (5) patients with acquired immunodeficiency syndrome due to lymphomatous infiltrates in the endoneurium, of which 2 cases of PN have been reported; (6) PN associated with organomegaly, endocrinopathy, M-component and skin lesions, certain cases being associated with a plasmocytoma and sometimes Castleman's disease but without any monoclonal gammopathy: (7) classic Guillain-Barré syndrome, prone to develop in patients with extraneural lymphoma but without any lymphomatous infiltrates in the peripheral nervous system; (8) certain cases (4 out of 16 in our series) where there is no clear relationship between PN and lymphoma, and there are mainly features of axonal degeneration. Inflammatory perivascular infiltrates were sometimes present in the epineurium.

Abstract
The plasma cell variant of Castleman's disease (angiofollicular hyperplasia) is an uncommon and poorly understood lymphoproliferative disorder which may be associated with a wide variety of systemic features. The clinical, pathological, immunophenotypic and genotypic features of a series of five cases are presented. The clinical manifestations were variable but systemic features were present in four cases. Histologically, all five cases were similar. The characteristic follicle-like structures are composed of concentric rings of B-lymphocytes with a mantle zone phenotype, surrounding an inner core of dendritic reticulum cells. The central regions are composed of plump cells that express Factor VIII related antigen, stain with Ulex europaeus I and are associated with laminin immunoreactivity. Many of these cells stain with Ki67 indicating cellular proliferation. Between these 'follicles', plasma cells are present interspersed between high endothelial venules. Using immunohistochemical techniques two cases were polyclonal, whilst in two others unequivocal lambda/IgA restriction was present; in the other case an intermediate picture of lambda/IgA predominance was apparent. Genotypic studies in three cases indicated immunoglobulin gene rearrangements but germ line T-cell receptor genes. The significance of the apparent clonal proliferation of plasma cells is discussed and a unifying model of Castleman's disease is proposed.

Abstract
POEMS syndrome is a multisystem disorder associated with polyneuropathy, organomegaly, endocrinopathy, a monoclonal protein (M-protein), and skin changes. The authors describe a patient with POEMS syndrome who has polyneuropathy of the upper and lower extremities, splenomegaly, impotence, IgA-lambda monoclonal protein (M-protein), and marked thickening of his skin. In addition, he has polycythemia vera. Although myeloproliferative disorders have been reported to occur in association with multiple myeloma, they have not been described with POEMS syndrome. The possible etiology of this association is discussed. This patient was successfully treated with melphalan and prednisone at the time of his initial diagnosis, but relapsed 10 years later. The relapse was treated with pulse doses of prednisone alone with complete resolution of his polyneuropathy and skin changes. This was accompanied by a fall in his IgA levels and improvement of his polycythemia.

Abstract
Four patients with polyneuropathy complicating the plasma cell variant of Castleman's disease (angiofollicular lymph node hyperplasia) are described. The neuropathy was predominantly motor and severely disabling. Vasculopathy, papilloedema, organomegaly, endocrinopathy, oedema and paraproteinaemia were variably present in these patients. Sural nerve biopsy showed changes of both demyelination and axonal loss. Capillary proliferation and endothelial hypertrophy in the epineurium and endoneurium, similar to that seen in affected lymph nodes, suggested that a diffuse vasculopathy may contribute to the neuropathy. Serum antibody activity against a variety of neural antigen preparations was not detected in any of the patients. Two untreated patients died. Substantial improvement in the neuropathy occurred in the two patients treated with cyclophosphamide and prednisolone.

Abstract
Seven young patients ranging in age from 8 to 19 years had surgically removed meningeal neoplasms with a peculiar myxoid-chordoid pattern. The tumors were surrounded by massive polyclonal lymphoplasmacellular infiltrates with follicles and germinal centers. The patients preoperatively manifested iron-resistant hypochromic microcytic anemia, and one of them had dysgammaglobulinemia and stunted growth. After the masses were removed, the blood picture of the patients normalized, and the adolescent with retarded somatic development resumed normal growth, but two patients developed local recurrence with identical histology and again became anemic. It appears that the peritumoral lymphoplasmacellular infiltrates, which in these instances may be regarded as reactive rather than primary cell proliferations, nevertheless brought about the type of systemic manifestations known as the Castleman syndrome, characteristically seen in patients with angiofollicular lymphoid hyperplasia (hamartoma) of soft tissues, or Castleman's tumor. In one of our patients the inflammatory infiltrate extended far into the surroundings of the meningioma, resulting in the erroneous initial diagnosis of "encephalitis" from a needle biopsy of the brain near the tumor.

A rare case of a 43-year-old man with polyneuropathy, monoclonal gammopathy, myeloma and Castleman's disease of plasma cell type was diagnosed. Immunohistological examination of the lymph node with Castleman's disease showed polyclonal binding while the myeloma was monoclonal containing IgA with lambda-light chains. At the immunoelectrophoresis IgA/IgA paraprotein was demonstrated. The possible pathogenetical relationship between polyneuropathy and plasmacytoma as well as Castleman's disease will be discussed.

Abstract
A rare form of plasma cell dyscrasia characterized by the various association of polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes has been termed POEMS syndrome. The pathogenesis of the multisystemic features of this syndrome remains unclear. Herein is reported a case of POEMS syndrome with striking clinical similarities with scleroderma, and microangiopathic glomerular lesions, as well as diffuse perivascular non-amyloid deposits, which could explain certain features of the syndrome, including peripheral nerve demyelination. It is proposed that a pathogenic role might be played by a non-immunoglobulin vasculotoxic component.
