Spontaneous tumour lysis syndrome associated with non-Hodgkin's lymphoma--a case report.

Spontaneous tumour lysis syndrome is characterized by hyperuricemia, hyperkalemia, hyperphosphatemia, metabolic acidosis and hypocalcemia, that occur even prior to the treatment of a neoplasm. This rare occurrence was encountered in a patient with non-Hodgkin's lymphoma (NHL), of follicular cell type. Conservative but intensive treatment led to complete resolution. Subsequent chemotherapy was well tolerated.

Plasma cell leukemia--a case report.

Plasma cell leukemia, occurring either de novo or in patients with long standing multiple myeloma, is the least common type of plasma cell dyscrasia. Histogenetically plasma cell leukemia is derived from terminally differentiated B cells. It is diagnosed by presence of absolute plasma cell count >2000/cm or >20% circulating plasma cells. Two cases of plasma-cell leukemia are reported here. Clinical spectrum and course of the disease, are discussed. Both cases (of primary plasma cell leukemia) had abrupt onset of disease, poor response to therapy and short survival time. Both presented with fatiguability and weakness. Evidence of organomegaly and radiological and hematological evidence of plasma cell leukemia, with thrombocytopenia and evidence of visceral involvement with leukemic cells, was seen in one case.

A study of fibroepithelial tumours of the breast.

Cytological parameters were studied in 18 fibroepithelial tumours of the breast including 8 benign phyllodes, 1 malignant phyllodes, and 9 fibroadenomas between 1999 to 2001. Cytology smears were studied without knowledge of previous cytodiagnosis by 3 different observers. Histopathologic parameters were studied in 18 fibroepithelial tumours by 3 observers. Cyto-histological correlation was carried out. Cytological criteria by Chinoy et al (1999) were utilized to give revised cytodiagnosis. Initial cytodiagnosis and revised cytodiagnosis were correlated with histopathological diagnosis. 8/9 cases of fibroadenoma (88%) studied were correctly diagnosed on FNAC after semiquantitative team approach as opposite to 44% initial cytodiagnosis. Cytological distinction between benign phyllodes and fibroadenoma was improved after semiquantitative approach to various parameters. Diagnosis of malignant phyllodes posed no problems in cytodiagnosis. Present study supports the role of FNAC in distinguishing benign from malignant phyllodes and distinguishing fibroadenoma from phyllodes tumour. The latter being a rare fibroepithelial tumour, its study is interesting.
