Parovarian neoplasms of wolffian duct origin are very unusual. This article presents the first report of a case of parovarian fibroma with heterotopic bone formation of probable wolffian duct origin. The tumor cells present among mature collagen bundles were fibroblast-like cells, while those at the sites of cellular proliferation were either undifferentiated mesenchymal cells or had differentiated into osteoblasts. In the bone matrix, the tumor cells had differentiated into osteoblasts and connective tissue had ossified.
源自中肾管的卵巢旁肿瘤非常罕见。本文首次报道了一例可能源自中肾管的卵巢旁纤维瘤伴异位骨形成的病例。成熟胶原束之间的肿瘤细胞为成纤维细胞样细胞，而细胞增殖部位的肿瘤细胞要么是未分化的间充质细胞，要么已分化为成骨细胞。在骨基质中，肿瘤细胞已分化为成骨细胞，结缔组织也已骨化。
