An ovarian teratoma was diagnosed in a one-year-old, virgin female, Strain 13 guinea pig that died unexpectedly. The left ovary was replaced by a 5.5 x 5 x 3 cm mass. Microscopically, dense fibrous connective tissue, immature neuroepithelium, central and peripheral nervous tissue, respiratory epithelium and cartilage were observed. A similar mass, 1.2 x 1 x 1 cm, composed largely of embryonal neural tissue, was adhered to the abdominal side of the diaphragm. The latter mass probably resulted from transcoelomic seeding by the ovarian tumor.
在一只意外死亡的1岁未交配雌性13品系豚鼠中诊断出卵巢畸胎瘤。左卵巢被一个5.5×5×3厘米的肿块取代。显微镜下，观察到致密的纤维结缔组织、未成熟的神经上皮、中枢和外周神经组织、呼吸道上皮和软骨。一个1.2×1×1厘米、主要由胚胎神经组织组成的类似肿块附着在膈肌腹侧。后一个肿块可能是由卵巢肿瘤经体腔播散所致。
