A case of primary trabecular carcinoid of the ovary apparently occurring from the foregut element of a mature cystic teratoma was reported. The tumor was found incidentally and resected surgically from a 56-year-old female. The cystic teratoma found in the tumor was composed of only respiratory epithelium except a colliculus which showed a picture of tonsil-like tissue. No thyroid tissue was found. The trabeculae of the tumor cells were longer and wavier near the cystic teratoma, while they were straight and short at the periphery. The tumor cells had argyrophil granules but negative in argentaffin granules. The electronmicroscopy revealed many round neurosecretory granules measuring from 170 to 290 nm in diameter. The histogenesis was also discussed.
报告了一例原发性卵巢小梁类癌,显然起源于成熟囊性畸胎瘤的前肠成分。该肿瘤是偶然发现的,从一名56岁女性患者身上手术切除。肿瘤内发现的囊性畸胎瘤仅由呼吸道上皮组成,除了一个呈现扁桃体样组织图像的丘状隆起。未发现甲状腺组织。肿瘤细胞小梁在囊性畸胎瘤附近更长且更弯曲,而在周边则又直又短。肿瘤细胞有嗜银颗粒,但亲银颗粒呈阴性。电子显微镜检查显示许多圆形神经分泌颗粒,直径为170至290纳米。还讨论了组织发生。
