Abstract

To determine the most common ocular lesions in horses with lymphosarcoma. Retrospective study. 79 horses histologically confirmed to have lymphosarcoma. Ophthalmic examinations were performed by a single individual. 21 of 79 horses had lesions involving the eye or ocular adnexa. Infiltration of the palpebral conjunctiva and eyelids was the most common lesion (n = 11). Other lesions included uveitis (n = 4), corneoscleral masses (2), third eyelid masses (2), and diffuse retrobulbar infiltrates (2). In horses with lymphosarcoma, ocular lesions may precede or be more obvious than lymph node enlargement or signs of visceral involvement. Early recognition of ocular lesions suggestive of lymphosarcoma may allow a more rapid diagnosis of lymphosarcoma in horses.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
