Preputial lymphangioma in a stallion: First report.
Abstract: This short communication describes a case of a 30-year-old stallion with a mass on the base of the penis causing paraphimosis. The patient was submitted to anti-inflammatory and diuretic therapy with no signs of improvement, so 16 days after the lesion was detected, the animal was euthanized. Necropsy was performed, and histopathological assessment of the lesion was conducted. The mass was composed primarily of channels and cavernous structures, lined by elongated cells of vascular origin, located in the preputium. The lesion was diagnosed as a preputial lymphangioma. To the authors' best knowledge, the anatomical location of this neoplasm (which is rare in veterinary medicine) has not been previously reported.

The research article presents a novel case study of a 30-year-old stallion diagnosed with a rare type of preputial tumor known as lymphangioma, marking the first reported instance of this kind in veterinary medicine.
Overview of the Case
- The article focuses on a unique veterinary case involving a 30-year-old stallion, which had developed a mass at the base of its penis causing a condition termed paraphimosis.
- The stallion was initially administered with anti-inflammatory and diuretic therapy, but it showed no signs of recovery. After 16 days, due to the failure of therapeutic treatments, the animal was euthanized.
Necropsy and Histopathological Evaluation
- Following the euthanasia, a necropsy was carried out – an autopsy applied to animals in veterinary medicine. This necropsy enabled the researchers to examine the cause of death and understand the nature of the mass in detail.
- On conducting a histopathological examination of the mass, it was revealed that the mass was composed of channels and large, hollow spaces or cavernous structures.
- All these structures were lined by elongated cells of vascular origin and found in the horse’s prepuce (the sheath of skin that covers the penis).
Novel Diagnosis
- From the histopathological findings, the mass was diagnosed as a preputial lymphangioma – a rare benign tumor made up of lymphatic vessels.
- To the best of the researchers’ knowledge, this is the first recording of such a neoplasm (abnormal and excessive growth of tissue) in this anatomical location in veterinary cases.
- Thus, this research underscores the need for further studies and investigation into rare veterinary pathologies like these to improve and enrich the field of veterinary sciences.
