Abstract
A 12-y-old, male Dachshund was presented for elective orchiectomy. The testes were of normal size. The left testis had numerous dark-red, blood clot-like foci within the vaginal tunic over the pampiniform plexus, epididymis, and testis. Histologically, the red foci were limited to the vaginal tunic and consisted of disorderly growing, variably sized, thin-walled blood vessels lined by a single layer of endothelial cells without mitoses and supported by a thin layer of pericytes. The blood vessels were distended by erythrocytes without thrombus formation. Endothelial cells had cytoplasmic immunolabeling for CD31; pericytes had strong cytoplasmic immunolabeling for α-smooth muscle actin. Our case of subclinical unilateral vascular hamartomas of the vaginal tunic in a dog has not been reported previously in domestic animals or humans, to our knowledge.

Abstract
Hamartomas are benign tumor-like lesions composed of disorganized growth of mature mesenchymal or epithelial tissues indigenous to the organ involved. Sporadically observed in ruminants, vascular, fibrous, nasal, and pulmonary hamartomas have been reported in calves; pulmonary and cutaneous forms have been reported in sheep. A full-term elk calf found dead had a large intrathoracic mass replacing the left caudal lung lobe and compressing other thoracic organs. Histologically, cross- and tangential sections of bronchi were separated by collagenous mesenchyme and irregularly shaped canaliculi and saccules resembling terminal bronchioles. Rarely present were regions in which saccules, lined by simple cuboidal epithelium, transitioned into attenuated epithelium lining fully developed alveoli. These findings are consistent with a pulmonary hamartoma. To our knowledge, pulmonary hamartoma has not been reported previously in a non-domestic ruminant.

Abstract
Congenital tumours and tumour-like lesions represent a group of rare disorders in both veterinary and human medicine that arise from tissue remnants and are detected during pregnancy or within the first 2-3 months of life. Different forms of congenital tumours and congenital tumour-like lesions have been reported in calves and their development is poorly understood. They often pose a diagnostic challenge and the referring nomenclature occasionally may be equivocal. Previous reports regarding tumour-like lesions, soft tissue tumours, vascular tumours, round cell tumours and neoplasms of the nervous, peritoneum and urogenital systems are summarized in this review, and the role of genetic factors in the development of these conditions is discussed.

Abstract
Hamartomas are primary, benign neoplastic lesions that most commonly derive from a single variably differentiated cell lineage. Here, we report an unusual case of a cardiac hamartoma. A 62-year-old woman presented with chest pain and palpitations. Serial imaging revealed a large slowly growing and highly vascularized left ventricular mass, which required surgical resection. Microscopically, the lesion was composed of nodular fibrovascular proliferation with haphazardly embedded muscle bundles and peripheral calcifications. Immunohistochemical studies revealed prominent muscle-specific actin positive and smooth muscle actin positive muscle fiber bundles within a disorganized fibrovascular stroma. This characterization is most consistent with cardiac mesenchymal hamartoma. Relevant differential diagnoses for this lesion include hamartoma of mature cardiac myocytes (HMCMs) and intramuscular hemangioma. The prominent smooth muscle differentiation of muscle bundles was incompatible with defining features of HMCM. Absence of S100-positive nerve and mature adipose cells distinguished this lesion from the recently defined, heterogeneous cardiac mesenchymal hamartoma. Forty-seven cases of cardiac hamartoma reported from 1970 to 2020 were reviewed to provide histopathologic context.

Abstract
An annular, reddened lesion with mild serosal hemorrhage and no tumorous mass formation was detected in the right uterine horn of a 37-week-old female Sprague-Dawley rat that had postpubertal vaginal bleeding. Histological examination revealed prominent proliferation of the endometrium, which occupied the uterine lumen. There were numerous aberrant vascular spaces filled with erythrocytes, proliferation of stromal cells, and inflammatory infiltrates including hemosiderin-laden macrophages in the endometrium. These vasculatures extended into the myometrium, and in a transverse section of the lesion, they were mostly distributed throughout the circumference of the uterus. They were irregular in shape and interconnected, forming a large vascular sinus and anastomosing reticular channels. In the area with serosal hemorrhage, the muscular layer covering the large irregular vascular space had undergone degeneration and necrosis. The lining cells of the vasculatures were often plump, and they protruded into the lumen and were arranged in a tombstone or hobnail manner. Immunostaining revealed that these cells were positive for von Willebrand factor and CD34. The aberrant vasculatures were not accompanied by pericytes or muscular layer, although a discontinuous muscular wall was present around some of them. From these results, the uterine lesion was diagnosed as a vascular hamartoma.

Abstract
A 9-year-old, female German Shepherd Dog presented with a firm bulging lesion at the tip of the tail. Histologically, the lesion was characterized by numerous poorly circumscribed clusters of vascular structures resembling capillaries that were separated by normal or mucinous connective tissues. The capillary-like vascular structures were composed of several layers: a single von Willebrand factor-positive endothelial cell layer with round, oval, or flattened hyperchromatic nuclei; and 1 or 2 surrounding spindle-shaped smooth muscle actin-positive pericyte layers. In the deep portion of the lesion, there were large vessels that showed morphological aberrations. These thin-to-thick-walled blood vessels corresponded to arteries and veins of varying diameters and were surrounded by fibrosis. The present case report describes a rare cutaneous vascular hamartoma, accompanied by aberrant arteriovenous structures.

Abstract
BACKGROUND This is the first description of the ultrasonographic findings in a cow with vascular hamartoma of the liver. CASE PRESENTATION Ultrasonographic examination of a six-year-old Swiss Braunvieh cow revealed an excessive number of hypoechogenic blood vessels in the liver parenchyma and a thrombus in the right hepatic vein. The activities of the liver enzymes and the concentration of bilirubin were within the reference ranges. At postmortem examination, a poorly delineated, non-encapsulated lesion, measuring approximately 10 cm × 10 cm in diameter, was found in the right liver lobe. The cut surface of the lesion was sponge-like and contained extremely dilated blood vessels, one of which was occluded with a branching red thrombus. A vascular hamartoma of the liver with thrombosis was diagnosed based on the histological findings. CONCLUSIONS To our knowledge, this is the first description of the ultrasonographic findings of vascular hamartoma of the liver in a cow. Hamartoma should be considered part of the differential diagnosis in cows with an abnormally large number of blood vessels in the liver parenchyma. This case report broadens the spectrum of liver diseases and ultrasonographic findings of the liver in cattle.
