Signet ring cell lymphoma: a rare variant of follicular lymphoma.
A case of signet ring cell lymphoma, the eighth in published reports is recorded. This rare tumour is a variant of follicular lymphoma which may be mistaken for metastatic carcinoma. The case has been studied by light microscopy, immunohistochemistry and electron microscopy and confirms that this sub-group has rather uniform characteristics. Observations on the possible origins of the vacuoles ...
متن کاملSignet-ring cell lymphoma of bone marrow.
A case of signet-ring cell lymphoma affecting bone marrow is reported. The tumour presented as multiple lytic lesions in the lumbosacral spine. A bone biopsy specimen showed the typical appearances of signet-ring cell lymphoma, and the cells stained positively with antiserum to CD20, though neither immunoglobulin light or heavy chains could be shown within the vacuoles. The patient subsequently...
متن کاملB cell signet-ring cell lymphoma of bone marrow.
A case of signet-ring cell lymphoma affecting the bone marrow and diagnosed by bone marrow trephine biopsy is reported. Normal marrow was replaced totally by cells with large central vacuoles, many of which displaced the nucleus to the periphery of the cell, imparting a signet-ring appearance. Initially, the favoured morphological diagnosis was metastatic signet-ring adenocarcinoma, but on immu...
متن کاملSignet ring cell lymphoma of T cell type
A rare variant of non-Hodgkin's lymphoma, signet ring lymphoma of T cell phenotype (only the fourth to be reported) in a 75 year old man was studied by light microscopy, immunohistochemistry, electron microscopy and gene rearrangement studies. Ultrastructurally, a wider spectrum ofcell size and nuclear shape was observed in this case than in the previously recorded cases. The morphology of the ...
متن کاملHISTIOCYTE-RICH B-CELL LYMPHOMA: A CASE REPORT OF A RARE VARIANT OF DIFFUSE LARGE B-CELL LYMPHOMA
The authors describe a case of histiocyte-rich B-cell lymphoma (HR-BCL), a variant of diffuse large B-cell lymphoma, in a 51-year-old man. The patient presented with large axillary lymphadenopathy. Histopathologic and immunohistochemical examination of lymph node biopsy revealed diffuse effacement of the lymph node architecture by reactive histiocytes and neoplastic CD20 positive B cells. ...
