Bılateral Sertolı-Leydıg Cell Tumor And Synchronous Adenocarcınoma Of The Colon In A Postmenapausal Woman Whose Left Ovary And Uterus Were In A Hernıa Sac: Report Of A Case. The Internet Journal of Surgery. 2009 Volume 22 Number 2.
Background: Sertoli-Leydig cell tumors are rare sex-cord stromal tumors, and seldom seen at postmenapausal women. It is an unfortunate situation when it is found near a colonic adenocarcinoma as a second primary tumor.Case presentation: A 76-year-old woman presented with anemia for a couple of years. She was operated for a left-sided hernia four years ago and she has a recurrent hernia on examination. Colonoscopy suggested an ulcero-vegetan tumor in the ascending colon. A right hemicolectomy with herniorraphy was planned. Laparotomy revealed that the hernia sac was containing the left ovary and uterus. The patient underwent right hemicolectomy, total hysterectomy and bilateral salphingo-oophorectomy. Pathological examination revealed the presence of a colonic adenocarcinoma coexistent with bilateral ovarian Sertoli-Leydig cell tumor.Conclusion: Clinical awareness and recognition of second tumors are important as they can change treatment strategies. Surgeons must be aware of the rare possibility of coexisting tumors.
Sertoli–Leydig cell tumor (SLCT) belongs to the group of sex cord-stromal tumors of the ovary and constitutes less than 0.5% of primary ovarian tumors1. The terms arrhenoblastoma, androblastoma, or gonadal stromal tumor of android type have all been used as synonyms for this cancer. Sertoli-Leydig cell tumors usually occur in young women and 70-75% of these tumors occur during the second and third decade of life2. Less than 10% of these tumors are seen either prior to menarche or after menopause2. They are usually unilateral and placed at the left ovary1. In two thirds of patients there is virilization, amenorrhea, hirsutism and gynecomastia caused by an elevated estrogen or androgen level.
The herniation of ovary and uterus into the inguinal canal is another rare situation and most of the reported cases are newborns and children3.
We presented the clinical and pathological findings of a patient with concomitant bilateral ovarian SLCT and colonic adenocarcinoma in a 76-year-old postmenopausal woman whose left ovary and uterus were herniated into the inguinal canal. To our knowledge, the following description of a postmenopausal woman is the first case in the literature with the synchronous tumors of colonic adenocarcinoma and ovarian Sertoli-Leydig Cell tumor found in an inguinal hernia sac.
A 76-year-old postmenopausal woman presented with anemia for a couple of years. Colonoscopy suggested an ulcero-vegetan tumor in the ascending colon. Endoscopic biopsy was reported as adenocarcinoma. She had been operated for a left-sided hernia four years ago and she had a recurrent hernia on physical examination. Biochemical examinations were normal except iron deficiancy anemia. Tumor markers were normal. A computed tomography scan of the abdomen and the pelvis revealed a tumoral mass located in the ascending colon in 4x2cm dimensions, a lymphadenopathy located in the right iliac region, a left-sided inguinal hernia and a 6x5x5cm hemangioma at the spleen.
A right hemicolectomy with herniorraphy was planned according to the preoperative examination. Laparotomy revealed that the hernia sac was containing the left ovary and atrophic uterus, and both ovaries had irregular contours. After peroperative gynecology consultation, the patient underwent right hemicolectomy, total hysterectomy and bilateral salphingo-oophorectomy. Histological examination of the ovaries showed tumoral structure consisting solid tubules of Sertoli cells with surrounding Leydig cells. Immunohistochemical examination showed diffuse strong expression of inhibin and no EMA, Vimentin and S100 expression. The histologic examination of the right colon revealed a pT3, pN0, grade II adenocarcinoma. According to these findings, the diagnoses of colonic adenocarcinoma and bilateral SLCT of ovary were determined.
Sex-cord stromal tumors of the ovary are uncommon ovarian malignancies, which account for less than 8% of all ovarian tumors4. Sertoli-Leydig cell tumors are rare, comprising less than 0.5% of all ovarian tumors, and contain Sertoli and/or Leydig cells in varying proportions. Reported cases vary between 2- and 76-year-old patients, but usually they occur in young women between 20-30 years5. Young and Scally reported a review of 207 cases and bilaterality was seen only in 3 of these cases6.
Clinically, 2/3 of the patients may suffer loss of secondary sex characteristics and androgenic effects. However, less than 50% of the patients with Sertoli-Leydig cell tumors have no endocrine manifestations2. The diagnosis is usually determined after the evaluation of endocrinologic symptoms. In our case, there were no endocrine manifestations and SLCT was incidentally diagnosed, so the hormonal status was not evaluated preoperatively.
In bilateral tumors, the point that there are two primary tumors or one is the metastasis of the other was not investigated. A metastasis of a well-differentiated tumor is not very probable. Also, bilaterality of these lesions with both components makes us consider that these are neoplasms or developmental defects according to hormonal status.
The hernia sac may contain structures such as ileum, jejunum, colon, omentum, vermiform appendix, stomach, ovary, uterus, urinary bladder, acute appendicitis, Meckel’s diverticulum or fallopian tubes7,8. Some of these are rarer than others. Although rarely encountered, most of the cases of inguinal hernia containing ovary and uterus were reported to be found in children3. Our case had a recurrent inguinal hernia and the first operation note could not be obtained. Constipation and obesity were thought to be the cause of the herniation.
These two rare situations were detected in our patient at the time of operation for colonic adenocarcinoma. Herniation of uterus and ovary at the same time makes our patient a research case.
Because of bilaterality of a rare tumor in a postmenopausal woman, the herniation of an ovary and the uterus, the absence of androgenic effects, good differentiation despite bilaterality, and coexisting colonic adenocarcinoma and splenic hemangioma, we thought that this case would be helpful in literature. Clinical awareness and recognition of second tumors are important as they can change treatment strategies. Surgeons must be aware of the rare possibility of coexisting tumors.
