Ovarian tumors in reptiles are uncommonly reported in the literature and for green iguanas previously reported cases include teratomas, one adenocarcinoma and one papillary cystadenocarcinoma. The present report is the first of a malignant ovarian teratoma in a green iguana. Complete and detailed pathological features, differential diagnosis and surgical management of malignant ovarian teratoma are discussed in this paper.
A 9-year-old intact female green iguana (Iguana iguana) with a clinical history of persistent anorexia and progressive abdominal distension was referred to the surgery department. On physical examination, a presumptive diagnosis of follicular stasis was established. Radiographic evaluation showed a large radioopaque mass within the abdomen, which was visible both in latero-lateral and ventro-dorsal exposures. Abdominal ultrasonography showed a large intra-abdominal mass, with numerous cyst-like structures filled with liquid and a heterogeneous aspect with hypoechoic areas. Exploratory laparatomy was thus suggested and the mass was removed surgically. The histologic findings of the neoplasm were consistent with those of ovarian malignant teratoma. Surgical excision of the mass in our case was considered curative and after a follow-up period of 6 months the animal has recovered completely.
A malignant ovarian teratoma has not been previously reported in green iguana and should be included in the list of differential diagnosis of ovarian tumors in this species. This report will contribute to a better understanding of the pathology of this rare tumor in green iguanas.
爬行动物卵巢肿瘤在文献中报道较少，对于绿鬣蜥，先前报道的病例包括畸胎瘤、一例腺癌和一例乳头状囊腺癌。本报告是首例关于绿鬣蜥恶性卵巢畸胎瘤的报道。本文讨论了恶性卵巢畸胎瘤完整而详细的病理特征、鉴别诊断及手术处理。
一只9岁未绝育的雌性绿鬣蜥（Iguana iguana），有持续厌食和进行性腹部膨胀的临床病史，被转诊至外科。体格检查时，初步诊断为卵泡停滞。影像学评估显示腹部有一个大的不透射线肿块，在侧位和腹背位影像中均可见。腹部超声检查显示腹腔内有一个大肿块，有许多充满液体的囊样结构，且呈现不均匀外观，有低回声区。因此建议进行剖腹探查，并通过手术切除肿块。肿瘤的组织学检查结果与卵巢恶性畸胎瘤相符。在我们的病例中，手术切除肿块被认为是治愈性的，经过6个月的随访，该动物已完全康复。
绿鬣蜥恶性卵巢畸胎瘤此前未见报道，应列入该物种卵巢肿瘤的鉴别诊断清单。本报告将有助于更好地理解绿鬣蜥这种罕见肿瘤的病理学。
