A fast growing, circumscribed, unilateral swelling of the right mandible of a juvenile horse was observed. Within few weeks, the continuously growing mass reached dimensions ranging from 7 to 10 cm in diameter and resulted in loss of the first deciduous premolar of the affected side. The animal was euthanized due to lesion progression. Histologically the mandibular swelling consisted of numerous variably sized vascular structures, partly filled with erythrocytes and embedded in a loosely arranged fibrous stroma within the medullary cavity of the mandible. Juvenile mandibular angiomatosis was diagnosed. To the authors' knowledge this is the first description of this rare entity in the mandible of a foal.

少见的少年马下颌血管增生的病例

观察到少年马右下颌骨快速生长,受限制,单侧肿胀。在数周内,不断增长的肿块直径达到7至10 cm,导致患侧的第一个落叶前磨牙消失。由于病变进展使动物安乐死。从组织学上讲,下颌肿胀由许多大小不等的血管结构组成,部分充满红细胞,并嵌在下颌骨髓腔内的松散排列的纤维基质中。诊断出少年下颌血管瘤病。据作者所知,这是在小马驹的下颌骨中对该稀有实体的首次描述。
