Plain-English summary
Two older female horses were diagnosed with a type of cancer called histiolymphocytic lymphosarcoma, which caused several fast-growing tumors just under their skin. Blood tests did not show any consistent changes that would typically indicate a problem. One of the horses had swollen lymph nodes, but there were no signs of cancer in their internal organs. Tests on the tumor tissue found certain bacteria, but there was no evidence of specific viruses. The treatment details and outcomes were not provided, so it's unclear how the horses responded to any treatment.
Abstract
Two aged mares with histiolymphocytic lymphosarcoma had multiple rapidly proliferating tumours in the subcutis. Consistent haematological changes were absent. One mare had lymph node involvement but no neoplastic lesions in the viscera. Microbiological examination of tumour tissue showed coryneform bacteria; there was no evidence of C-type or lytic viruses or of reverse transcriptase. Prominent intramitochondrial crystalline inclusions were in histiocytic tumour cells.
