A case of an eosinophilic leukemoid reaction associated with metastasizing malignant melanoma and thrombotic eosinophilic parietal endocarditis in a 58-year-old white male is reported. No similar cases were found in the literature. The leukemoid reaction with leukocytosis of up to 102 300 white cells per microliter , 65% of which were eosinophils, was observed during the last two months of life of the patient, who died of multiple metastasis of malignant melanoma. The primary malignant melanoma had been excised four years before death. The parietal endocarditis was localized on the posterior wall of the left ventricle and was found incidentally at autopsy. The association of leukemoid eosinophilic reaction with consecutive eosinophilic thrombotic parietal endocarditis is believed to be part of a paraneoplastic syndrome. 63 published cases of paraneoplastic eosinophilic leukemoid reaction and 6 published cases of malignant tumor with eosinophilia and additional parietal endocarditis were found. The pathogenesis of these conditions is discussed.

About 15% of patients with cancer have cerebrovascular lesions, resulting from 4 kinds of disorders sometimes intermingled in advanced disseminated cancer: coagulation disorders, direct effects of the tumor, infections and therapeutic measures. Infarction, hardly less frequent than hemorrhage, mostly complicates lymphoma and carcinoma. Hypercoagulation states, such as chronic disseminated intravascular coagulation, nonbacterial thrombotic endocarditis, and nonmetastatic cerebral venous thrombosis account for about 50% of cases. Tumor emboli, as seen in intravascular malignant lymphomatosis, arteritis related to aspergillus, granulomatous angiitis with or without herpes zoster and radiation-induced atherosclerosis are rarer. Cerebral hemorrhages, excluding bleeding from the metastases of choriocarcinoma and melanoma are mainly associated with leukemia by acute disseminated intravascular coagulation as in promyelocytic leukemia, by leukostasis or by pancytopenia. Both infarction and hemorrhage rarely reveal the neoplasia. Lesions are often small and disseminated, and therefore produce a picture of diffuse acute or subacute encephalopathy rather than acute focal deficits. Finally, there may be no relationship between the cerebrovascular event and the neoplasia, and atherosclerosis or traumatic subdural hematoma may well be the causal factor.

We report the clinical features and outcome of 16 patients with cryoglobulinaemia. Two patients with Type I cryoglobulinaemia both had IgG kappa monoclonal paraproteins. Nine of 10 with Type II disease had monoclonal IgM kappa and polyclonal IgG; one had monoclonal IgG kappa and polyclonal IgG in the cryoglobulin. Underlying disorders identified in 3 of the 4 Type III patients were Sjogren's syndrome, infective endocarditis, and non-A non-B hepatitis and HTLV III infection. The commonest presenting features were rash in 94 p. 100 (ulceration 25 p. 100), arthralgia in 63 p. 100 (erosive arthritis 32 p. 100), renal disease in 63 p. 100, neurological involvement in 56 p. 100, hepatomegaly in 32 p. 100 and splenomegaly in 32 p. 100. Major associated conditions were progressive bronchiectasis in one case, and severe peripheral vascular disease in another; underlying malignancy was found in 2 cases (lymphoma and malignant melanoma). Treatment was with plasma exchange (PE) and immunosuppressive drugs (ID) in 10, PE alone in 3, ID alone in 2 and antibiotics [corrected] in 1. Fourteen of 16 patients showed an initial clinical response and fall in cryoglobulin levels. Four patients have died, one each from gastro-intestinal haemorrhage, sepsis, pulmonary embolism and lymphoma. Of the remaining 12 patients, all are symptomatically controlled and 10 have persisting cryoglobulinaemia (3 on PE and ID, 2 on PE, 2 on ID and 3 on no treatment). Of the two cases in whom cryoglobulinaemia resolved, one (Type II) had received PE and ID and the other (Type III) had been treated with antibiotics and surgery for infective endocarditis.

The search for a cancer is part of the classical investigation of unexplained venous thrombosis. Arterial thrombosis associated with neoplasia is more rare. The authors report two cases in which arterial thrombosis was the final event of their malignant disease. The first case had abacterial thrombotic endocarditis and disseminated intravascular coagulation at the origin of multiple thrombotic complications. The initially unknown cancer was a pancreatic adenocarcinoma. The second case presented with acute occlusion of the iliac artery after ablation of a malignant melanoma. Despite embolectomy with a Fogarty catheter and effective anticoagulation, the thrombosis recurred several times at the same site. The clinical features and the mechanisms of these two cases suggestive of Trousseau's syndrome are discussed.

Amyloidosis of the head and neck region may represent a local amyloidoma or a manifestation of systemic disease. Involvement of major salivary glands by either primary or secondary forms of amyloidosis is very rare. We describe a case of systemic amyloidosis that initially presented as submandibular gland mass and was diagnosed by fine-needle aspiration (FNA). A 69-year-old male presented with submandibular mass. His past medical history was significant for left forearm melanoma that was excised 6 years ago and tricuspid valve endocarditis after valvular replacement 3 months prior to FNA of the submandibular gland. The patient had no symptoms or clinical and laboratory data suggestive of amyloidosis. FNA specimen showed salivary gland tissue and abundant amorphous material, which stained positive for amyloid with Congo red stain and showed typical birefringence when examined by polarized microscopy. Further workup of the patient revealed generalized amyloidosis with multiorgan involvement by the disease. This case demonstrates that FNA can be a useful technique in the diagnosis of unsuspected amyloidosis.

Background: Fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) is an imaging technique largely used in the management of infective endocarditis and in the detection and staging of cancer. We evaluate our experience of incidental cancer detection by PET/CT during IE investigations and follow-up. Methods and Findings: Between 2009 and 2018, our center, which includes an "endocarditis team," managed 750 patients with IE in a prospective cohort. PET/CT became available in 2011 and was performed in 451 patients. Incidental diagnosis of cancer by PET/CT was observed in 36 patients and confirmed in 34 of them (7.5%) (colorectal n = 17; lung n = 7; lymphoma n = 2; melanoma n = 2; ovarian n = 2; prostate n = 1; bladder n = 1; ear, nose, and throat n = 1; brain n = 1). A significant association has been found between colorectal cancer and Streptococcus gallolyticus and/or Enterococcus faecalis [12/26 vs. 6/33 for other cancers, p = 0.025, odds ratio = 3.86 (1.19-12.47)]. Two patients had a negative PET/CT (a colon cancer and a bladder cancer), and two patients, with positive PET/CT, had a benign colorectal tumor. PET/CT had a sensitivity of 94-100% for the diagnosis of cancer in this patient. Conclusions: Whole-body PET/CT confirmed the high incidence of cancer in patients with IE and could now be proposed in these cases.
