A 2-year-old male free-ranging white-tailed deer (Odocoileus virginianus) was diagnosed with bilateral expansile tumors of antler origin. The deer was found dead by a landowner in High Springs, Florida. Two roughly spherical, multilobular, broad-based, bony, velvet-covered masses originated from each antler pedicle. These masses replaced or displaced many of the bones and soft tissues of the skull and extended through the left cribriform plate and the right petrous temporal bone, compressing portions of the brain. Microscopically, the masses closely resembled normal-growing antler, containing all the elements thereof but with areas of necrosis and hemorrhage suggestive of ischemi or trauma. Tumorlike outgrowths termed antleromas have been described in free-ranging and captive cervids and typically are associated with disruptions in the seasonal rise and fall of circulating testosterone necessary for normal antler growth, casting, and regeneration.
一只2岁的野生白尾鹿（弗吉尼亚鹿）被诊断出患有双侧源自鹿角的膨胀性肿瘤。这只鹿被佛罗里达州海斯普林斯的一位土地所有者发现死亡。两个大致呈球形、多叶、基部宽阔、骨质、覆盖着鹿茸的肿块分别起源于每个鹿角基部。这些肿块取代或移位了颅骨的许多骨骼和软组织，并穿过左侧筛板和右侧颞骨岩部，压迫部分脑组织。显微镜下，这些肿块与正常生长的鹿角非常相似，包含鹿角的所有成分，但有坏死和出血区域，提示存在缺血或创伤。在野生和圈养的鹿科动物中都曾描述过类似肿瘤的生长物，称为鹿角瘤，通常与正常鹿角生长、脱落和再生所需的循环睾酮季节性升降紊乱有关。
