Haematopathology practice: the commonest problems encountered in a consultation practice
1Department of Pathology, University College London, London, UK. p.isaacson@ucl.ac.uk
Although not specifically recognized as a subspecialty of histopathology, haematopathology has a long history of specialist practice in the UK, with a few centres attracting large numbers of referred cases. The specialist nature of haematopathology has been enhanced by the advent of immunohistochemistry and, more recently, molecular genetics, which now play a major role in the diagnosis of haematopoietic and lymphoid neoplasms. Problems encountered by non-specialist pathologists, and reflected in those cases submitted for consultation, include difficulties in the differential diagnosis of certain benign lymphoproliferative disorders from lymphoma and the precise classification of lymphomas which may have an impact on therapeutic decisions. Lymphomas that frequently pose problems include common lesions such as follicular lymphoma and more esoteric disorders such as T-cell/histiocyte-rich large B-cell lymphoma. This review is an attempt to clarify a logical approach to the differential diagnosis of these lesions.

01:27Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
