Abstract
Introduction: The Uterus is a major female hormone responsive reproductive organ which is subjected to vast range physiological changes, benign and malignant disorders.
Aims and Objectives: The study was undertaken to see different patterns of histomorphological lesions in uterus and cervix in hysterectomy specimens and to study its correlation with respect to age and clinical presentation.
Materials and Methods: This study is a prospective analysis of 155 hysterectomy specimens received in Department of Pathology in DR B R Ambedkar medical college and hospital in Bangalore during a 18 months period from June 2017 to December 2018.
Results: In the present study commonest type of hysterectomy was Total abdominal hysterectomy and the commonest clinical indication being Menorrhagia in 63(40.64%) cases. The peak age of incidence of hysterectomy was noted in the 5th decade (38.91%). The commonest lesion encountered was Chronic non specific cervicitis in 86(55.40%) cases and leiomyoma in 57(36.77%) cases, 6 cases (3.87%) of carcinoma endometrium, 9 cases (5.80%) of carcinoma cervix and 11 case (7.00%) of cervical dysplasia were encountered. The rare and interesting lesions encountered in the present study were 2(1.28%) case of blue nevus Cervix and 2 case (1.28%) of Benign Cellular Leiomyoma and 1 case of (0.64%) Lymphoepithelioma like SCC cervix
Conclusion: Hysterectomy still remains one of the most commonly done procedure in the gynecology department. Histomorphological analysis of lesions of uterus and cervix is mandatory for establishing final diagnosis.

The female reproductive tract is a complicated but fascinating system comprising of the external and the internal genitalia with vagina, uterus, fallopian tubes and ovaries. Uterus, additionally called the womb and the cervix are the vital female reproductive organs, subjected to numerous non neoplastic and neoplastic diseases. The uterus consists of the endometrium and the myometrium, which are continuously stimulated by hormones, denuded monthly of its endometrial mucosa and inhabited periodically by fetuses.[1] Together with the lesions that affect the cervix, the lesions of the corpus of the uterus and the endometrium account for most patient visits to gynecologists.[2]
Hysterectomy is the surgical removal of the uterus and is performed by a gynecologist. Historically Charles Clay performed the first subtotal hysterectomy in Manchester England in 1843 and the first Total abdominal hysterectomy was done in 1929.[3] Hysterectomy still remains one of the most prevalent gynecological procedure performed worldwide in spite of other treatment modalities for many gynecological disorders.
This study is entitled to study and understand the various gross and histomorphological findings in the uterus and cervix of hysterectomy specimens and their distribution with respect to age of the patient and the mode of presentation.
This prospective type of study was carried out in the Department of Pathology, Dr. B.R. Ambedkar medical college and hospital, Banglore over a period of 18 months between ‘Jun 2017 to Dec 2018’.There were 155 hysterectomy specimens received from gynecology department included in this study. Hysterectomy specimens with indications for pathologies related to fallopian tubes and ovaries were omitted from the study. Clinical details of the patients were obtained from the requisition forms received along with the hyssterectomy specimens and were entered in the proforma.
All the received hysterectomy specimens were immediately fixed with 10% formalin saline in the ratio of 1:10. After 24 hours of fixation, the specimens were thoroughly examined grossly and then multiple representative bits were taken, processed and embedded in paraffin. Three to five micron thickness sections were taken; slides were made and stained with routine H & E stain. The histomorphological findings of uterus and cervix were noted and then these findings were correlated with age and clinical diagnosis.
A total of 155 hysterectomy specimens were analyzed in this study. The incidence of hysterectomies in relation to the age was studied and depicted in the Fig. 1. Age ranged from 18 years to 97 years with mean age of 41.78. In our present study, peak age of hysterectomy done was found in 5th decade i.e 41 – 50 yrs with 61 of cases. (Fig. 1) The commonest type of the hysterectomy encountered was total abdominal hysterectomy in 66(42.75%) cases. (Table 1)

Discussion
Hysterectomy is the most commonly performed major gynecological surgery throughout the world. It is a successful operation in terms of symptom relief and patient satisfaction and provides definitive cure to many diseases involving uterus as well as adnexa.[4]
This study was undertaken to analyze and understand the histomorphological spectrum of uterine and cervical lesions in hysterectomy specimens and to determine its correlation with respect to age and clinical diagnosis of the patient.
In our study commonest age group for hysterectomy specimens was 5th decade, which is in concordance with studies by Patil HA et al,[5] Ajmera Sachin K et al[6] and Yogesh Neena et al.[7]
In our study, the incidence of abdominal hysterectomy was higher than the vaginal as in the studies done by Ajmera Sachin K et al,[6] Sunita Malik et al[8] and Ankur gupta et al.[9]
The present study revealed Menorrhagia as most common indication which was found to be in concordance with studies done by Ticku et al[10] and Karthikeyan et al.[11]
Endometrial polyp in this present study was 7 cases (4.51%) which was seen to be in concordance with study conducted by Yogesh Neena et al which was 3.47%.[7]
In this present study endometrial hyperplasia accounts to 34 cases (21.9%). This finding was found comparable with the studies conducted by Ojeda VJ [12]and Ranabhat et al,[13] which showed 22.3% and 16% cases of endometrial hyperplasia respectively.
In our study endometrial carcinoma was encountered in six cases (3.80%), and mainly found in post menopausal age group presenting with post menopausal bleeding. The study done by Ankur gupta et al[9] has similar findings.
Among the myometrial lesions, leiomyoma accounts for majority comprising of 66 cases (42.58%), which is in comparison with studies done by Ajmera Sachin K et al[6]in 170 cases (48.6%) and Stewart and Arti.[14] Majority of the studies done on the histopathological analysis of hysterectomy specimens so far reveals that uterine fibroids are the most common pathology to be encountered in the uterus.
Adenomyosis (22.58%) was second most common pathology in our present study which was in accordance with study conducted by Sunita malik et al[8] showing 21%. Adenomyosis is very rare and difficult to diagnose pre operatively as it has no specific clinical symptom of its own. It is usually diagnosed only after hysterectomy by histomorphological examination of the specimen. Around 26 cases (16.77%) in this study revealed the presence of both leiomyoma and adenomyosis.
Non neoplastic diseases of uterine cervix are predominantly inflammatory and are more common. A vast majority of cases with inflammatory pathology had no specific cause and chronic non specific cervicitis being the most common lesion encountered accounting to 55.40% which is in comparable with other studies done by Nwachokor & Forae[15] and Garewal et al.[16]

Adenomyosis (22.58%) was second most common pathology in our present study which was in accordance Intraepithelial neoplasia is a very critical in the the natural history of cervical carcinoma. The importance of detecting and treating patients at this stage is that the progression of intraepithelial neoplasia into carcinoma can be prevented.In this present study cervical dysplasia accounts for 9 cases (5.80%) which is in comparison with Vijaya Gattu et al[17] and Cervical cancer accounts for 8 cases (5.16%) which is also in concordance with Vijaya Gattu et al.[17]
Adenomyosis (22.58%) was second most common pathology in our present study which was in accordance with study conducted by Sunita malik et al[8] showing 21%. Adenomyosis is very rare and difficult to diagnose pre operatively as it has no specific clinical symptom of its own. It is usually diagnosed only after hysterectomy by histomorphological examination of the specimen. Around 26 cases (16.77%) in this study revealed the presence of both leiomyoma and adenomyosis.

Uterine cervix is a very unusual site for pigmented melanotic lesions.Blue nevi are infrequent incidental findings encountered in the cervix of hysterectomy specimens from middle aged females. In our study 2 cases (1.20%) of blue nevus cervix was encountered as a incidental finding in the hysterectomy specimen

Hysterectomy still remains one of the most common treatment modality worldwide, thereby forming substantial work load in the histopathology department. This present study provides a limelight on the various histomorphological findings of uterus and cervix encountered in hysterectomy specimens at our institution. The histomorphological analysis was found to correlate well with the clinical diagnosis of the patients and quite a few lesions were also encountered completely as pure incidental findings. Hence, it becomes mandatory that every hysterectomy specimen, even if it is grossly appearing to be normal, it should be subjected to exhaustive histomorphological examination so as to ascertain better post operative management and follow up.
