Tumors of the spleen are rare compared to the incidence of such tumors in other parenchymatous organs. Their classification has varied with both time and author. They can be divided into two main categories: nonlymphoid and lymphoid. The most common nonlymphoid tumors are the vascular tumors which include benign and malignant haemangiomas, littoral cell angiomas, lymphangiomas and haemangioendo...

Seventy-three patients with advanced non-Hodgkin lymphoma were treated with bleomycin, Adriamycin, cyclophosphamide, vincristine (Oncovin) and prednisone (BACOP), administered intensively during a 7-wk induction course followed by intermittent cycles every 3 wk for a total of 28 wk. The objective response in 44 evaluable nonleukemic patients with diffuse histology was 86%, with 66% achieving a ...

Eighteen patients with advanced non-Hodgkin's lymphoma other than the diffuse histiocytic type were treated with a combination of adriamycin, vincristine, ifosfamide and prednisolone (AVIP). The objective response rate was 83% (15/18); 61% (11/18) achieved complete remission. The median duration of complete remission was 11 months ranging from 2 to 39+ months. Eleven of the 18 patients are stil...

HLA, A, B, and DR typing was done on seven of 10 patients with lymphoma, and six patients with carcinoma, all of whom had a flat small intestinal mucosa. Sixty-nine per cent (nine of 13) had HLA B8 and 71% (five of seven) had DR3. The corresponding levels for the local coeliac population are 76% and 84% respectively and the local non-coeliac population 43% and 44%. Two of the patients with lymp...

Follow-up data for 11 patients with non-Hodgkin's lymphoma treated with partially purified human leukocyte interferon is presented. The interferon preparation used was 0.1% pure and treatment consisted of 5 x 10(6) U given intramuscularly twice daily for 60 injections. One complete, three partial, and three minimal responses were observed in five of seven evaluable patients with nodular non-Hod...

Originally believed to be of histiocytic origin, regressing primary cutaneous anaplastic large-cell lymphoma is a CD30 (Ki 1) positive T-cell lymphoma with histologic high grade malignancy, but with an often favorable clinical course with regression of individual lesions. We present a case of a 69-year-old white woman with an 8-month history of noduloulcerative lesions on her right lower leg, o...

Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy (SHML), is a systemic disease involving nodal and extranodal tissues. We report a 48-year-old female with recurrent nasal obstruction due to polypoidal masses involving the nasal sinuses, turbinates and septum bilaterally, and lumps in the right infra-orbital region and region of the right lacrimal sac. ...
