A patient of Hodgkin's disease with pulmonary involvement is described. Demonstration of Reed-Sternberg cells in the sputum confirmed the diagnosis of pulmonary involvement.
A retrospective analysis was performed of 238 patients, aged 12 years and older, with non-Hodgkin's lymphoma presenting to the All India Institute of Medical Sciences, New Delhi, India, between September 1975 and December 1982. Pathologic material was reviewed and classified according to the modified Rappaport classification. The most common histologic type encountered was diffuse histiocytic lymphoma (39%), followed by diffuse poorly differentiated lymphocytic lymphoma (29%), and diffuse mixed histiocytic and lymphocytic lymphoma (9%). Nodular lymphomas constituted 9% of all non-Hodgkin's lymphomas. A lower frequency of nodular lymphomas, a lower median age of onset (45 years), and a higher male to female ratio (4.5:1) as compared with Western countries was observed. Survival information on 90 patients revealed no effect of age, sex, stage of disease, and "B" symptoms on survival, whereas histologic diagnosis had a significant influence on survival (P less than 0.05). A median survival of 24 months in 58 patients receiving chemotherapy is comparable to that reported by other investigators.

An analysis of 128 cases of Hodgkin disease seen at the Department of Pathology, All India Institute of Medical Sciences, New Delhi, during the period 1968--1974 is presented with reference to histopathological and clinical findings. A male preponderance is noted in all age groups, and this is most noticeable in children under 15 years of age. There is a predominance of cases with the histologic subtypes associated with a poor prognosis (mixed cellularity and lymphocyte depleted). Only nine cases of nodular sclerosis type were seen.

BACKGROUND: Gastrointestinal tract (GI) is the most frequently involved extra nodal site in non-Hodgkin's lymphoma (NHL). Surgery, radiotherapy and chemotherapy (CT) have been used mostly in various combinations, but lately chemotherapy alone has emerged as an effective option. The purpose of this study is to evaluate efficacy of CT alone in treatment of primary GI-NHL and to compare the results with combined CT+surgery. SETTING AND DESIGN: Retrospective analysis of case records of GI NHL patients. MATERIALS AND METHODS: Over a 15-year period (1986-2000), 77 new cases of primary GI-NHL were registered at our center. GI-NHL was defined according to standard criteria. All patients received chemotherapy. RESULTS: The median age was 32 years (Range 9-80). Endoscopy / CT guided biopsies were performed in 42% (32) of patients for the purpose of diagnosis. Laparotomy was done in 58% (45) of patients to establish a diagnosis or as primary or debulking treatment. Stomach and intestines were involved in 47% (36) and 53% (41) patients respectively. Early stage disease was present in 37% (29). Seventy eight percent of tumors were intermediate to high grade, 43% (33) received only CT while 57% (44) received CT+surgery. Five years EFS and OS were: 72% and 65% for all patients; 72% and 67% for CT only group; 60% and 64% for CT+surgery group (P=.05). Four patients died of neutropenic infection. CONCLUSION: Organ-preservation strategy using chemotherapy alone (CT) can be successfully employed in a significant number of patients with primary GI-NHL.
We report a rare association of carcinoma and tuberculosis of the stomach. It is difficult to explain the simultaneous occurrence or a causal relationship of the two diseases.
BACKGROUND: The prognosis of patients with Hodgkin's disease has improved significantly over the past two decades, primarily as a result of the development of curative combination chemotherapy. However, data on the presentation and results of treatment in Indian patients are scarce. We reviewed the clinical and pathological data and the treatment outcome of patients with Hodgkin's disease seen at our centre over the last 15 years. METHODS: The case records of 289 patients diagnosed to have Hodgkin's disease at our centre between 1977 and 1992 were reviewed. Their clinical characteristics, treatment outcome and prognostic factors for survival were analysed. RESULTS: The median age of the patients was 26 years with 30% being in the third decade. The male:female ratio was 4:1. The mixed cellularity histological subtype was the most common (68.5%), followed by nodular sclerosis (8.9%). 'B' symptoms were present in 73% of patients and 9.4% had bone marrow involvement. At the time of presentation, 70% of patients had advanced disease (stage III: 36%, stage IV: 34%). Complete response to treatment was obtained in 65.7% of patients while 17.3% had partial response. The predictors of decreased overall survival were age > 40 years, presence of 'B' symptoms, lymphocyte depletion histological subtype and stage IV disease. Disease-free survival was influenced by the presence of 'B' symptoms, bone marrow involvement and stage IV disease. CONCLUSION: Hodgkin's disease in Indian patients has a distinct clinico-pathological profile. Combination chemotherapy has high response rates even in patients with advanced disease at presentation.
Primary malignant mesenchymal tumours of the greater omentum are rare. We report a 40-year old man with a painless abdominal lump of two months duration. At laparotomy, the mass was found to be arising from the greater omentum. A near-total omentectomy was done. Histological examination of the resected tumour revealed features consistent with malignant fibrous histiocytoma.

A case of pseudolymphoma from India is being reported which had been masquerading for quite some time as a case of borderline leprosy. The patient has been having for the past 16 years, recurrent, occasionally pruritic, multiple, bilateral, erythematous papules and plaques, which on casual examination elsewhere had suggested leprosy.
