A three and one-half-year-old girl and a 12-year-old boy presented with features of the two clinical presentations of Castleman's disease or giant lymph node hyperplasia. The girl presented with anemia, fever, night sweats, hypergammaglobulinemia, and a palpable abdominal mass. Her symptoms were consistent with those seen in the plasma-cell type of this disease. The boy presented with acute appendicitis and a left hilar mass was noted on his chest radiograph. His asymptomatic presentation was typical of the hyaline-vascular form. Both patients are well without evidence of recurrence four years following resection. Castleman's disease is a benign disorder of lymph nodes that occurs rarely in children. Since the original report in 1954 we could find only 18 cases in the 16-year and younger age group and our patient with the symptomatic form represents the youngest patient reported in the English literature. The management requires surgical resection of the enlarged nodes both for diagnosis and therapy since the enlarged nodes can mimic malignant tumors of the lymphoid system. No recurrences have been reported in pediatric patients.

Appendiceal lymphomas are exceedingly rare, constituting around 0.015% of all gastrointestinal lymphoma cases. Burkitt's lymphoma is the second most prevalent pathology, diagnosed in 25.9% of patients. We report a case of a 36-year-old male admitted with acute abdominal pain with 2 days of evolution, localized in the right lower quadrant associated with hyporexia, but no fever. On examination he presented abdominal tenderness on the right iliac fossa. A diagnosis of acute appendicitis was made clinically. At the post-operative follow up, 2 weeks later, he presented a low back pain of high intensity, associated with swelling of the abdomen, night sweats, daily fevers and weight loss. The histopathological exam of the appendix revealed diffuse and transmural lymphoid proliferation. Immunohistochemistry suggested high grade B-cell lymphoma indicative of Burkitt's lymphoma. This patient was staged as a IVxB lymphoma and was submitted into polychemotherapy with a complete clinical response in 8 months.
