AIMS: Familiarity with benign uterine smooth @entity5 with unusual growth patterns by gynaecologists and pathologists is essential in avoiding misdiagnosis and overtreatment. CASE DETAILS: An enlarged uterus in a 35-year-old @entity1 contained numerous, ill-defined nodules with marked hydropic changes which showed an extrauterine extension. Histologically, although some nodules had an appearance of conventional @entity2909 , the predominant part of the lesion was characterized by ill-defined spindle cell nodules with marked hydropic changes and irregular dissection of the myometrium. The cellularity was variable from area to area and there were neither nuclear atypia nor mitotic figures. No coagulative @entity5 @entity39 was observed. The extrauterine components, which were in continuity with the intrauterine nodule, were histologically identical to the intrauterine nodules except for the complication of @entity46 . Immunohistochemically, the @entity5 cells were positive for @entity2277 , @entity2283 , alpha-smooth muscle actin and muscle actin (HHF35). The @entity5 was DNA diploid by flow cytometry. The @entity1 was well and without disease 6 months after hysterectomy. CONCLUSIONS: This @entity5 illustrates that rare benign smooth @entity5 can proliferate in dissecting and extrauterine growth patterns, findings that should not be confused with @entity361 .
