Case report: sonographic appearance of cavernous haemangioma of the testis.

We present the sonographic findings and pathologic correlation in a rare case of cavernous haemangioma of the testis. We conclude that cavernous haemangioma of the testis should be included in the differential diagnosis of hyperechoic intratesticular masses.

Magnetic resonance imaging for the assessment of residual masses after treatment of non-Hodgkin's lymphomas.

Eight patients with non-Hodgkin's lymphoma who were in clinical remission but showed residual masses after therapy were examined with magnetic resonance imaging at 1.5 T at the end of therapy, with the sequences TR/TE:500/35,500/70,2000/35 and 2000/70. Residual masses were found in lymphoid areas (7), spleen (3) and kidney (1).

[The treatment of large-cell non-Hodgkin's lymphomas with the MACOP-B protocol].

Background: To investigate the results of the treatment of large-cell non-Hodgkin's lymphomas (LCNHL) with the MACOP-B chemotherapy protocol.

Methods: 20 patients with the following inclusion criteria were treated: LCNHL with a definite majority of large lymphoid cells and absence of previous therapy, HIV infection or severe underlying diseases.

Results: Three patients died during therapy and 15 (75%) achieved a complete remission.

[Intraparenchymal non-neoplastic residual masses after treatment of large-cell non-Hodgkin's lymphoma with intensive chemotherapy].

We report two patients with large-cell non-Hodgkin's lymphomas who were treated with intensive chemotherapy (MACOP-B), and in whom large isolated intraparenchymal masses (splenic in one case, renal in the other) were found with computed tomography after clinical remission. It was found at surgery that both masses were constituted by acellular necrotic material, without tumoral infiltration and limited by fibrous tissue. The finding of these residual masses in patients in remission raises problems of approach, as they may be nontumoral and not require new therapy.
