[Methods] The clinical and pathological analysis of 28 cases of uterine hypertrophy hospitalized for surgery were performed. [Results] Uterine hypertrophy caused by the symptoms of enlarged uterus and menstrual disorders Often misdiagnosed as uterine fibroids, accounting for 65% of misdiagnosed cases.Pathological examination showed that the uterus in patients with varying degrees of uniformity increased muscle thickness of 25 ~ 35cm; small leiomyoma (diameter less than 1cm) 4 cases, accounting for 14%, with endometrial polyps in 6 cases, accounting for 21%, with endometrial hyperplasia 18 cases, accounting for 64%; myometrial pathological changes in 26 cases, accounting for 93% of smooth muscle cell hypertrophy, muscle There were 2 cases of fibrous tissue hyperplasia around the blood vessels and 7% of them. [Conclusion] There are no specific symptoms and signs of uterine hypertrophy and should be misdiagnosed. Differential diagnosis should be done. Pathological examination showed hypertrophy of smooth muscle cells and endometrial hyperplasia Long and polyps
