The most commonly done gynaecological surgery worldwide is hysterectomy.
Myometrial lesions contribute to majority of cases with abnormal uterine bleeding.
Leiomyoma and adenomyosis are most common lesions seen in the myometrium.
The present study was undertaken to identify the various types of myometrial
pathologies in hysterectomy samples.
This is a two-year retrospective cross-sectional study done from January 2017 to
December 2018, in the Department of Pathology, Kodagu Institute of Medical
Sciences, Madikeri. All the patients who underwent hysterectomy and
myomectomy for myometrial lesions of uterus were included in the study.
Hysterectomy specimens showing secondaries, gross infection, massive
haemorrhage and necrosis were excluded from the study. Gross appearance and
microscopic pathology were noted and results were analysed.
In this study, 148 specimens were included. Age range was from 20 years to 65
years. Histopathological examination revealed that 58.25 % of myometrial lesions
were present in the age group of 41 to 50 years followed by age group of 31 to
40 years. Histopathological examination done showed the following diagnosis in
patients - leiomyoma (85.13 %), adenomyosis (8.79 %) and leiomyoma with
adenomyosis (6.08 %).
The commonest histopathological lesion in myometrium was leiomyoma (85.13
%) followed by adenomyosis (8.79 %). It is mandatory to examine the
hysterectomy specimens adequately to diagnose myometrial lesions.
