Plain-English summary
A 13-year-old brown Austrian warmblood mare was diagnosed with a type of cancer called cutaneous multilocular T-cell lymphosarcoma, which is a form of malignant lymphoma. Over an 8-month period, her condition worsened, leading to weight loss, lameness in her left hind leg, and a slight increase in the size of the tumors, which were mostly covered by normal skin, although one had developed an ulcer. Doctors used ultrasound to monitor the tumors, which helped them understand how they were affecting nearby tissues and muscles, and they were able to take samples for testing. After examining the horse after death, they confirmed that the cancer had spread into the muscles in three areas. Unfortunately, the treatment details and outcomes were not provided in the report.
Abstract
Clinical, ultrasonographic and pathological findings of a cutaneous, multilocular T-cell lymphosarcoma (malignant lymphoma) in a 13-year-old, brown Austrian warmblood mare are reported. The horse was under clinical observation, and the tumours were sonographically monitored over an 8 month period, revealing worsening of body condition, weight loss, lameness of the left hindlimb and a slight increase in the tumours size. Most of the tumours were covered by normal skin, one showed ulceration. Ultrasonography of the tumours allowed accurate anatomical localization in relation to the adjoining tissue, assessment of their internal structure, of involvement of adjacent muscles and of a regional lymph node, and it facilitated the percutaneous fine-needle aspiration. Necropsy confirmed muscular infiltration in three locations. Light microscopy and immunohistology led to the diagnosis of a T-cell lymphosarcoma.
