A 52-year-old man, who had been diagnosed as having alcoholic liver cirrhosis, presented a chronic nephritic syndrome due to hepatic glomerulosclerosis. Ten months before death, massive proteinuria exceeding 40 g/day was noted. A renal biopsy revealed diffuse mesangial sclerosis, associated with an IgA deposition consistent with hepatic glomerulosclerosis. Although the nephrotic syndrome subsided with immunosuppressive therapy, he died of hepatic failure. Postmortem examinations disclosed a diffuse, medium-size B-cell lymphoma, involving the peritoneal and retroperitoneal organs and an IgA-positive plasmacytosis. His massive proteinuria seems to have been caused by the paraneoplastic syndrome of a malignant lymphoma.

Paraneoplastic syndromes rarely affect patients with head and neck cancer. Four patients with different histological types of head and neck cancer are presented in which the primary malignancy was preceded and/or accompanied by a paraneoplastic syndrome. In the first patient erythrodermia preceded the diagnosis of a nasopharyngeal carcinoma. The second patient presented with a B cell lymphoma of the nasopharynx in association with the syndrome of inappropriate secretion of arginine vasopressine (Schwartz-Bartter syndrome). In the third patient paraneoplastic polyarthritis had been diagnosed 5 months before a hypopharyngeal carcinoma was diagnosed. In the last patient the paraneoplastic anti-Hu positive encephalomyelitis was associated with a primary malignancy in the larynx with neck metastases. Diagnostic procedures, treatment and follow-up of these patients are reported and accompanied by a review of the literature.

The occurrence of non-Hodgkin's lymphoma in systemic sclerosis is an uncommon event. In our scleroderma cohort, a case of primary gastric B-cell lymphoma was diagnosed in 2007. The patient was a 45-year-old woman suffering from late systemic sclerosis sine scleroderma in whom non-Hodgkin's lymphoma presented with progressive weight loss, later with gastrointestinal symptoms. Subsequently, we retrospectively analyzed the charts of 251 systemic sclerosis patients consecutively admitted to our Unit from 2000 to 2008 to search for other non-Hodgkin's lymphoma cases (prevalence, 0.49%). Then we performed a Pubmed search for "systemic sclerosis & non-Hodgkin's lymphoma," limited to the English language. Twenty detailed cases of such an association were found, pointing out the following: non-Hodgkin's lymphoma seems to be associated to old age, female sex, diffuse cutaneous subset and early disease; B-cell lymphoma subtypes are the majority; the interval between systemic sclerosis and lymphoma onset is usually short; systemic sclerosis could present as a paraneoplastic syndrome in some cases. We concluded that, although rare, the association of systemic sclerosis and non-Hodgkin's lymphoma may not be coincidental and the clinician should be aware of the risk for lymphoproliferative disorders in scleroderma patients. This is the first description of non-Hodgkin's lymphoma in systemic sclerosis sine scleroderma. The insidious onset of gastric lymphomas, mimicking the most common features of gastrointestinal involvement in systemic sclerosis is underlined.

Gastric adenocarcinoma developing concomitantly with a lymphoma is rare. Furthermore, B-cell lymphoma, originating from lymph nodes, with eosinophilia is extremely rare. We report here a case with a synchronous diffuse large B-cell lymphoma (DLBCL) and an early adenocarcinoma of the stomach. In addition, this case seemed to be associated with paraneoplastic cutaneous vasculitis caused by hypereosinophilic syndrome (HES) with mixed cryoglobulinemia (MC). Many neoplastic diseases that affect internal organs display cutaneous manifestations, which may be the presenting signs and symptoms of the underlying malignancy. In particular, the association between cutaneous vasculitis and malignancy has been widely reviewed, and recently neoplasms have been suggested to produce antigens and the resultant immune complex formations, activating the serum complement, thus cause paraneoplastic vasculitis. In this case, severe eosinophilia and cryoglobulinemia with low complements were observed in a laboratory test. A biopsy specimen from a skin lesion revealed leukocytoclastic vasculitis with severe perivascular infiltration of eosinophils. The cutaneous vasuculitis was considered to be a manifestation of HES with MC, although there were no etiological factors of HES and MC. Therefore, the vasculitis seems to be a symptom of paraneoplastic syndrome in this case. Our finding suggests that the potential presence of malignancies should be kept in mind as a possible underlying disorder especially in the presence of HES with MC; this possibility is interesting also as regards at least part of the pathogenesis for paraneplastic syndrome.

Paraneoplastic syndromes are most often diagnosed in the setting of a known malignancy. It is not uncommon for a paraneoplastic disorder to develop before a cancer is identified. While syndrome of cerebellar degeneration has been identified as a paraneoplastic manifestation of Hodgkin's lymphoma, thymoma, lung and breast cancer, ovarian and testicular tumors, melanoma, renal cell carcinoma, follicular lymphoma and adenocarcinoma of stomach, its association with non-Hodgkin's lymphoma and particularly diffuse large B-cell lymphoma has not been established previously. This case report describes the primary presentation with signs of paraneoplastic cerebellar degeneration as the only manifestation of an underlying diffuse large B-cell lymphoma making it the first of its kind to be formally reported. Furthermore, it also includes the identification of associated paraneoplastic antibodies for this particular syndrome.

An 87-year-old woman was diagnosed with primary diffuse large B-cell lymphoma of the pancreas by endoscopic ultrasonography-guided fine needle aspiration. Complete remission was achieved after treatment with six courses of R-CHOP chemotherapy. However, two and a half years later, she was readmitted because of weakness during walking. At this time, laboratory tests revealed hypercalcemia associated with high plasma levels of parathyroid hormone-related protein (PTHrP), but bone lesions were not detected. Although computed tomography only revealed splenomegaly, we suspected a recurrence of her malignant lymphoma because she also had marked elevation of soluble interleukin-2 receptor and lactate dehydrogenase levels. Bone marrow examination revealed the involvement of Burkitt's lymphoma cells with malignant transformation. Immunohistochemical analysis confirmed that hypercalcemia was caused by a paraneoplastic syndrome related to PTHrP-producing B-cell lymphoma cells. Unfortunately, the patient's general condition rapidly deteriorated, and she died soon after admission. Our case is unusual because of the presentation of bone marrow relapse of malignant lymphoma.

Paraneoplastic syndromes are a heterogeneous group of malignant diseases caused by events which involve endocrine, immune and metabolic aspects and whose symptoms vary according to the substance produced and the primary tumor. Hypercalcemia is a frequent complication in cancer patients. Prognosis of cancer patients with hypercalcemia is usually poor. A factor called parathyroid hormone related peptide, whose actions are similar to those of the parathyroid hormone, is thought to be the most common cause of malignancy associated hypercalcemia. Non-islet hypoglycemic cell tumor consists of a rare syndrome characterized by the presence of a solid tumor and severe fasting hypoglycemia determined by an insulin-independent pathway. We report a case of a 59-year-old-man with a renal tumor and a T-cell rich large B cell lymphoma who was hospitalized due to severe hypercalcemia and hypoglycemia. The laboratory examination reported hypercalcemia with inhibited PTH and hypoglycemia with inhibited insulin secretion, arriving to the conclusion of tumoral peptide production. He received denosumab and corticoid therapy. The patient died one month later despite initial improvement after medical treatment. While a single paraneoplastic manifestation may be expected in most tumors, the coexistence of two or more of them is rare, except in hepatocellular carcinomas, and it has not yet been described in renal tumors.
