The authors report a case of primary Ki-1 lymphoma of the brain. The patient was a 4 1/2-year-old black girl who presented with a 4- and 5-day history of headaches, nausea, vomiting, neck stiffness, and difficulty in walking. Computed tomography (CT) scan of the brain showed two discrete densities in the left occipital lobe and in the brain stem. Magnetic resonance imaging (MRI) showed multiple densities scattered over the brain surface and brain stem. Microscopically, the tumor was an anaplastic neoplasm that diffusely infiltrated brain parenchyma. The neoplastic cells were large with amphophilic cytoplasm, large nuclei with irregular nuclear contours and prominent nucleoli. A high mitotic rate including atypical mitotic figures was noted. Immunohistochemical stains showed diffuse strong positivity for CD30 and moderate focal staining for epithelial membrane antigen. Leukocyte common antigen, cytokeratin, neuron specific enolase, monocyte/macrophage and B- and T-marker stains were negative. The histology was characteristic for Ki-1 large cell lymphoma. Cytologic examination of cerebrospinal fluid (CSF) demonstrated similar neoplastic cells. This is one of the first reports of this variant in the pediatric population.

Here we report an unusual case of T-cell lymphoma presenting as ascites. A 49-yr-old woman was admitted to the hospital for abdominal discomfort associated with increasing abdominal girth over the course of 3 mo. She also complained of nausea, vomiting, and diarrhea. On physical examination, a tense and distended abdomen and edema of the lower extremities were noted. Neither hepatosplenomegaly nor lymphadenopathy was found. A CT scan of the abdomen and pelvis showed a large abdominal/pelvic mass surrounding the small bowel and omentum and small nodes in the para-aortic and mesenteric regions. The cytospin prepared from the peritoneal fluid was hypercellular and composed of a population of monotonous, noncohesive cells with a high nuclear/cytoplasmic ratio and a single prominent central nucleolus. The cells were positive for leukocyte common antigen and Leu-22 (CD43) but negative for keratin, L26, UCHL-1, kappa, lambda, CD3, Ki-1 (CD30), S-100, and carcinoembryonic antigen. Morphologic and immunologic findings were suggestive of T-cell immunoblastic lymphoma. Peripheral T-cell lymphomas rarely present as ascites; this case demonstrates the value of effusion cytology in making this diagnosis.

Posttransplant CD30(+) (Ki-1) anaplastic large cell lymphoma (ALCL) is rare. A review of the literature revealed only 3 such cases. All 3 cases were developed after single-organ transplantation. We describe CD30(+) (Ki-1) ALCL in a dual-organ (liver and heart) transplantation recipient. The patient was a 68-year-old white female who underwent an orthotopic heart transplantation in 1999 and a liver transplantation in 2000. She presented with nausea and was found to have CD30(+) (Ki-1) ALCL by pathologic examination of the gastric antrum biopsy specimen. To our knowledge, this patient represents the first reported case of posttransplant CD30(+) ALCL following a dual-organ transplantation.
