EBVD and alternating MOPP/EBVD with or without localized field radiotherapy in advanced or unfavorably presenting Hodgkin's disease.

PATIENTS AND METHODS: Ninety-five patients with previously untreated, advanced or unfavorably presenting Hodgkin's disease were recruited in ten centers. Twenty-five patients with stage II-A-bulky disease received four courses of EBVD (epirubicin, bleomycin, vinblastine, dacarbazine) plus involved field radiotherapy (Group 1); 24 patients in stage I-B, II-B and III-A received 6 courses of EBVD (11 of them also received radiotherapy on bulky localizations (Group 2); 46 patients in stage III-AS > or = 3 nodes, III-B and IV received MOPP/EBVD 4 + 4 courses (Group 3). RESULTS: Eighty patients (84%) achieved CR, eight patients (8%) a PR, five patients did not respond and two progressed during therapy. CRs were achieved by 23/25 patients (92%) in Group 1, 21/24 (87%) in Group 2 and 36/46 (78%) in Group 3. The mean duration of follow-up was 33.3 months (range 5-69). There were three deaths from directly treatment-related causes. Twelve patients suffered chronic toxicity, including six who suffered lung toxicity and two who developed secondary myelodysplasia. CONCLUSIONS: The results achieved in this co-operative study are similar to those reported by most single-Institution trials and those with adriamycin-containing regimens. Long-term toxicity deserves careful consideration.

[Colliculus hemorrhage].

We report the case of a patient with mesencephalic hematoma involving only the quadrigeminal plate. One case of superior and 3 cases of inferior colliculus hematoma have already been reported. Involvement of the quadrigeminal plate frequently follows a pontine or an anterior mesencephalic hemorrhage. The cause of these hematomas may be due to cryptic malformations of the quadrigeminal plate or primitive small size hemorrhages possibly related to the nature of the arterial system. Patients with inferior colliculus lesions present a typical symptomatology consisting of trochlear nerve palsy contralateral to the lesion or bilateral, contralateral hemiparesthesiae and acuphenes. Superior colliculus lesion causes upgaze palsy, visual blurring, dizziness and left upper lip paresthesiae. The cause of the different signs and symptoms in both types of lesion are discussed.

[Splenic lymphoma with villous lymphocytes. A clinical case].

Splenic lymphoma with circulating villous lymphocytes is a rare B-lymphoproliferative disorder of the elderly which has been only recently defined. Clinical features are spleen enlargement of various degree without lymphadenopathy and an indolent course, with a long survival, in most cases. Absolute lymphocytosis is present; atypical circulating lymphocytes show a medium or large size, a small prominent nucleolus and a few short and thin cytoplasmic protrusions and projections (villi), which are distributed at one or both poles of cell surface. Reaction for tartrate-resistant acid phosphatase is almost always negative. Immunological markers are as follows: CD 19+, CD 20+, CD 22+, CD 11c+/-, CD 5-, CD 23-, CD 25-, HLA DR+, SmIg+. Differential diagnosis with other chronic lymphoproliferative disorders, particularly chronic lymphocytic leukemia, hairy cell leukemia, prolymphocytic leukemia, follicular and mantle-cell lymphoma in leukemic phase, is based on clinical and immunocytomorphologic criteria. Bone marrow biopsy shows involvement of different degree and pattern; splenic involvement mostly occurs in the white pulp; hepatic nodules in portal areas may be present. Cytogenetic alterations are often present but not specific, such as increased serum LDH and monoclonal gammopathy. No therapy should be made in asymptomatic patients. In case of systemic symptoms, symptomatic splenomegaly or cytopenias, treatment may consist on splenectomy, splenic irradiation or alkylating agents. A case of splenic lymphoma with circulating villous lymphocytes is reported; differential diagnosis, particularly with other B lymphoproliferative disorders, is discussed.
