[Diffuse hemangiomatosis of the liver and spleen in an adult].

Diffuse hemangiomatoses are extremely rare in adults. The etiology and natural history of the disease are not well understood. A case of diffuse hemangiomatosis of the liver and spleen associated with progressive liver failure, thrombocytopenia, and disturbance of blood coagulation (comparable to Kasabach-Merritt syndrome) is presented in a 62-year-old male. We describe the histopathological and immunohistochemical findings and illustrate the morphological aspects of differential diagnosis, distinguishing the disease from other vascular proliferations.

Long-term survival of renal graft complicated with Burkitt lymphoma.

A 10-year-old boy with steroid-resistant nephrotic syndrome developed disseminated Burkitt lymphoma 2 years after renal transplantation. Treatment consisting of reduction of immunosuppression and polychemotherapy was initiated, and induced complete tumor remission. A severe cerebellar syndrome attributed to high-dose cytarabine occurred during treatment. The patient recovered partially from this complication. Immunosuppression had to be resumed 2 years later because of a chronic rejection. Finally, at last follow-up, the patient was alive with a stable creatinine of 180 micromol/l.

Carcinoid tumor of the spleen: report of a case.

Carcinoid tumors are uncommon tumors of the neuroendocrine system. They grow slowly and may remain silent for years before presenting with carcinoid syndrome. A diagnosis of asymptomatic carcinoid tumor is difficult. Wide resection of the primary tumor and metastatic lesions is the first choice of treatment. Primary carcinoid is sometimes distributed throughout the entire body, but it is rare in the spleen. We herein present a rare case of a symptomless carcinoid tumor that predominantly invaded the spleen with liver metastasis.

Stable E rosette-forming lymphocytes in the peripheral blood in non-Hodgkin's lymphoma.

The peripheral blood of 49 patients with non-Hodgkin's lymphoma and the same number of normal controls was examined for the presence of lymphocytes forming rosettes with sheep erythrocytes at 37 degrees C (stable E rosettes). Nineteen lymphoma patients but only five normal controls showed increased absolute levels. (P less than 0.01). There was no correlation between the occurrence of increased Stable E Rosette levels and the histological type of lymphoma but there appears to be a positive relationship with the presence of clinical stage III-IV disease at presentation (P = 0.011). It is suggested that stable E rosettes represent an immunological response to residual lymphoma in our patients. A longitudinal study in one patient is reported in detail to demonstrate the occurrence of fluctuations in stable E rosette levels coinciding with clinical changes.

Remote recurrence of renal cell carcinoma.

A fifty-nine-year-old man with abnormal liver function tests, fever, and weight loss was found to have a recurrence of renal cell carcinoma which had been latent for twenty-two years. Reactive hepatitis was a prominent associated finding. The important features of remote recurrence of renal cell carcinoma are discussed.

Gamma-glutamyltranspeptidase in murine lymphomas.

Five murine lymphoma cell lines were assayed for the content and activity of gamma-glutamyltranspeptidase (GTT). All lines [S49; L-12; 230-23-8 (C57 Black); 2M3 and RA3-2C2] contained detectable amounts of GGT. The specific activities of GGT were low and ranged between 1.2 and 2.3 mU/mg protein in cells growth in vitro. A highly malignant variant of the S49 line was also grown in vivo in BALB/c mice. This subline invariably produces both solid and ascitic tumors with infiltrations into the pancreas, liver and spleen. GGT levels in the tumor cells were low and independent of tumor type (solid, ascitic), location, passage number or inoculum size. Infiltrations of S49 tumor cells in liver and spleen were invariably GGT--negative as judged by histochemical examination. GGT activities in suspension cultures prepared from solid, as well ascitic tumors were low. Occasional high GGT activity of solid tumors was due to the presence of pancreas cells in them. The only host tissue significantly responding to the presence of tumors by elevated GGT levels was the liver. Compilation of data from this study and those of others clearly indicates that low GGT level is a typical property of tumors originating in the immune system.

[Isolated pseudo-tumoral tuberculosis of the spleen. A case report].

INTRODUCTION: The tuberculosis isolated tumoral spleen is rare, even in the countries to strong tubercular endemic. EXEGESIS: From an observation, concerning an important, tumoral and isolated splenomegaly in 48-year-old-man. The authors put the accent on his tumorous variety by the clinic, the imagery and on macroscopic appearance of the operative piece. Are discussed the isolated character, the way of dissemination, the site of initial infestation and the deceitful character of haematological manifestations. A splenectomy to diagnostic and therapeutic goal have been realised, associated to the chemotherapy. CONCLUSION: This is an expression of the profound organ's tuberculosis rich on endothelial reticular system. It's mean a singular topography of the bacillary lesion and a great distribution of the tubercular affect.

Contribution of radionuclide imaging to radiation oncology.

Radionuclide imaging has been helpful to oncologists in the initial evaluation and follow-up of patients with primary and metastatic disease. With the introduction of ultrasound and computed tomography, there has been some reduction in the number of radionuclide imaging procedures. These imaging modalities should be used to complement one another. With the introduction of single-photon emission computed tomography in clinical nuclear medicine, there will be a significant improvement in the sensitivity, accuracy, and quantitative ability to detect abnormal lesions. There are intensive efforts in the development of tumor imaging using new agents. Specific antibodies for surface tumor antigens can be labeled with radioisotopes and used as tools for screening primary tumors and metastatic lesions. Therefore, for the present, radionuclide imaging will continue to contribute to clinical oncology.

[Extreme hypogammaglobulinemia disclosing large granular lymphocytes with hepatosplenorenal infiltration].

We report a case of large granular lymphocytosis, or chronic "natural killer" lymphocytosis, a newly described entity. We were able to demonstrate the proliferative character of the disease by the finding of karyotype abnormalities. This case was remarkable for the pre-existence, for at least three years, of severe hypogammaglobulinaemia, for the very slow course of the proliferative process and for the progressive and tumoral infiltration of the spleen and liver, then kidney.

Anaplastic large cell lymphoma of the spleen.

A case is presented of CD30+ anaplastic large cell lymphoma of the spleen. The patient, a 61 year old woman with a history of chronic lymphocytic leukemia (CLL) was seen for the sudden development of splenomegaly with thrombocytopenia. A splenectomy was performed which showed massive replacement of the spleen by a population of large atypical lymphoid cells showing bizarre nuclear forms and multinucleated tumor cells reminiscent of Reed-Sternberg cells. Immunohistochemical studies showed strong membrane and dot-like paranuclear positivity in the majority of the atypical cells for CD30, with coexpression in many of the cells for CD15. Additionally, the cells also strongly reacted with CD3, UCHL-1, EMA and LCA. The present case illustrates an unusual variant of anaplastic (CD30+) large cell lymphoma sharing histologic and immunophenotypic features that overlap with those of Hodgkin's disease. The history in this patient of CLL with sudden development of splenomegaly raises the possibility of transformation of CLL into a high-grade lymphoma (Richter's syndrome). The possible pathogenetic implications of this phenomenon are discussed.
