The light-microscopic and ultrastructural features of a paravaginal epithelioid smooth muscle tumor that contained prominent myxoid stroma are reported. Because of its prominent myxoid component and the soft tissue location, this tumor was difficult to classify by histologic features alone. The ultrastructural studies demonstrated a constellation of features that have been accepted to be indicative of smooth muscle origin. The histogenesis and differential diagnosis are discussed. The elucidation of the biologic behavior of this peculiar variant of smooth muscle tumor awaits accumulation of further cases.
报告了一例含有显著黏液样基质的阴道旁上皮样平滑肌瘤的光镜和超微结构特征。由于其显著的黏液样成分和软组织定位，仅通过组织学特征很难对该肿瘤进行分类。超微结构研究显示了一系列被认为可指示平滑肌起源的特征。讨论了其组织发生和鉴别诊断。这种特殊类型平滑肌瘤的生物学行为的阐明有待更多病例的积累。
