Nineteen patients with fungal splenic abscesses included 16 with leukemia, one drug user, one patient with Cushing's syndrome, and one without predisposing causes. Fifteen had persistent fever; six had esophageal or mucocutaneous candidiasis. Abdominal pain occurred in seven patients, splenomegaly occurred in six, and left abdominal mass occurred in one. Three chest x-ray films showed left pleural effusions; two had elevated left hemidiaphragms, two had left-sided infiltrates, and one was normal. Sixteen of 17 technetium Tc 99m sulfur colloid scans were abnormal, as were 15 gallium citrate Ga 67 scans. Two computed tomographic studies revealed splenic defects. Candida was the cause in 15 cases, Aspergillus was the cause in three cases, and Blastomyces dermatitidis was the cause in one case. Sixteen patients underwent splenectomy, 12 receiving postoperative antifungal therapy. Fifteen survived regardless of underlying disease or hepatic microabscesses.

A 39-yr-old man presented to our hospital with unexplained erythrocytosis and hypertension. His follow-up for erythrocytosis had begun 2 yr earlier in another hospital and he had been diagnosed with polycythemia rubra vera. On admission to our hospital he was hypertensive (165/95 mmHg) and, except for the presence of moon-like face and facial plethora, his physical examination was normal. His hemoglobin concentration was 19.2 g/dl, and hematocrit was 58.9% with an increased red blood cell mass of 58 ml/kg as measured by radioisotope (Cr51). Blood film, other hematological indices except for elevated leukocyte alkaline phosphatase score, arterial gas analysis, and examination of aspirated bone marrow were all normal. An abdominal ultrasonography showed no evidence of splenomegaly. A diagnosis of probable secondary erythrocytosis was made. Early-morning serum cortisol and 24-h urinary free cortisol concentration as well as serum ACTH were high. Serum cortisol was not suppressed by low-dose dexamethasone, but suppressed by high-dose dexamethasone. Pituitary magnetic resonance imaging showed no lesion. After inferior petrosal sinus sampling suggesting right-central ACTH secretion, the patient underwent transnasal-transsphenoidal pituitary adenomectomy. Both hypercortisolemia and erythrocytosis regressed completely after the adenomectomy. After the operation, the patient's hemoglobin concentration and hematocrit decreased steadily, and 1 month post-adenomectomy his hemoglobin is 14.9 g/dl and hematocrit 44.8%. Thus, Cushing's syndrome should be a routine part of evaluation of unexplained polycythemia.

Castleman disease is a rare idiopathic non-neoplastic lymphoproliferative disorder with 2 clinical (unicentric and multicentric) and 3 histomorphological (hyaline-vascular, plasma-cell and mixed) forms identified. The case report given here describes the 3-year experience with therapy in a patient, male born 1961, diagnosed with multicentric plasma-cell Castleman disease (HIV and HHV-8 negative) with the finding of generalized lymphadenopathy and splenomegaly. During first line treatment (R-CHOP: rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone, 3 cycles in total, 12/2008-2/2009) the development of bilateral upper and lower limb edemas with clinical manifestation of vasculitis occurred and a restaging computed tomography (CT) examination revealed a stable finding of the lymphadenomegaly. Greater success was achieved with thalidomide regimen (CTD: cyclophosphamide, thalidomide, dexamethasone, 10 cycles, 3/2009-1/2010) leading to reduction in the size of the hypervascularized lymph nodes (almost by 50%) as well as their radiopharmaceutical (fluorodeoxyglucose) uptake as seen on a combined positron emission tomography and computed tomography (PET/CT) scan imaging. Thalidomide was given daily at doses between 100 and 200 mg. We returned to the CTD regimen again in April 2010 after a short period of monoclonal antibody tocilizumab treatment (400 mg intravenous in 2-week intervals with 50% dose reduction due to a limited supply of the drug, 5 doses in total) during which edemas reoccurred with a CT scan finding of stable lymphadenomegaly. However, the renewed regimen with thalidomide was stopped after 2.5 cycles due to adverse effects of thalidomide (neuropathy) and corticoids (Cushing syndrome). In September 2010, after enrollment in the Celgenes Compassionate Use Program we were able to start treating the patient with the derivative of thalidomide, lenalidomide, at a dosage of 25 mg on days 1-21 in a 28-day cycle, 15 cycles in total (10/2010-12/2011). The monotherapy with lenalidomide was very well tolerated by the patient without any effects of myelotoxicity, thromboembolism or relapses of edemas and vasculitis, additionally now with apparent improvement of fatic disorder and the patients motor abilities. Thus, lenalidomide represents an attractive alternative agent for patients with Castleman disease after rituximab and cytostatics failures. It has a favourable safety profile and could be therefore considered for administering in first line treatment.
