Ten patients with diffuse large cell (histiocytic) lymphoma of the spleen had a characteristic clinical presentation and pathologic findings. Patients presented with left upper quadrant pain, fever, weight loss, and an elevated sedimentation rate. Imaging studies revealed an enlarged spleen with a discrete mass in all cases. Moderate to massive splenomegaly (average weight, 1025 g) was found at laparotomy; a single large mass or multiple confluent nodules with extensive central necrosis replaced 85% to 90% of the parenchyma. The tumor transgressed the splenic capsule in nine of ten cases, and either invaded or was adherent to the diaphragm, stomach, pancreas, or abdominal wall. Lymph nodes in the splenic hilum or retroperitoneum were frequently involved. Seven patients were in Ann Arbor Stage II, and three were in Stage I. Eight of the ten lymphomas were subclassified as centroblastic (large noncleaved cell) and two were immunoblastic. The B‐cell lineage of six tumors was established by the presence of monoclonal immunoglobulin. Despite combination chemotherapy, with or without radiation, three of the seven patients whose follow‐up was adequate died in less than 2 years; four are alive at 7, 12, 12, and 81 months, respectively, the last two with recurrent lymphoma. Large cell lymphoma of the spleen is a likely diagnosis in patients who present with left upper quadrant pain, fever, and radiographic evidence of a splenic mass.
Eighty-one patients with preinvasive carcinoma of the vocal cord, seen over a thirteen year period, were reviewed histologically and analyzed for response to treatment. Sixty-seven cases were clinically T1 and fourteen cases T2 (by virtue of extension of disease beyond the vocal cord). All patients had mobile cords. Histological criteria for in situ carcinoma and the spectrum of microscopic patterns are presented. Sixty-nine patients were treated by external beam radiotherapy--the remainder by a variety of surgical procedures. Five and ten year actuarial, recurrence-free rates 83% and 75%, respectively for the group treated by irradiation. No difference in local control was observed when analyzed for: 1) dose response, 2) initial extent of disease, 3) treatment plan, or 4) histologic diagnosis. Analysis of failures reveals that 15/17 patients with local failure were salvaged, eleven of these patients requiring laryngectomy. Time to appearance of recurrence ranged from seven to one hundred and seven months.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
