Abstract
We present the case of a 27-year old female with an ovarian tumor and alpha-fetoprotein (AFP) of 1210 ng/m, a right salpingo-oophorectomy was performed and had conservative complementary staging by gynecologic oncologists. The histopathological report was primary hepatoid carcinoma of the ovary (HCO), clinical stage IA, complementary treatment was adjuvant chemotherapy with BEP and remains clinical, imaging and biochemically disease free in three years follow up.
1. Introduction
Hepatoid carcinoma of the ovary (HCO) is a very rare group of extrahepatic aggressive tumors with similar hepatocarcinoma (HCC) clinical and pathological characteristics, unknown histogenesis, and most frequent in postmenopausal patients. This histopathologic variant is classified by some authors within the epithelial origin of ovarian tumors, however, there is still controversy about its origin. HCO was first reported in 1987 Ishikura and Scully (Ishikura and Scully, 1987), who carried out a review of rare undifferentiated ovarian tumors, and found 5 cases with hepatocellular morphology and histologic characteristics without liver injury, 38 cases have been reported to date.
2. Case presentation
A peruvian 27-year old female, childless, referring three months with pelvic pain, she had an abdominopelvic ultrasound reporting right adnexal mass. It was operated in her hometown on January 2016, performing right salpingo-oophorectomy. The pathology report was epithelioid malignant neoplasm suggestive of undifferentiated ovarian carcinoma, annex size was 10 cm and serum alpha fetoprotein (AFP) of 1210 ng/ml, for what it was referred to the National Institute of Neoplastic Diseases (INEN).
On admission, physical examination was normal, new reading plates was performed and reports: Primary hepatoid carcinoma of ovary (Fig. 1), fallopian tube without pathologic alterations or tumor involvement, ovarian capsule neoplasm free. No evidence of endodermal sinus component. Immunohistochemistry PANKERATIN (+), AFP (+), GLYPICAN (+), HER PAR 1 (+), SALL-4 (focal+) (Fig. 1).

Immunohistochemical findings.
ABDOMINAL MR was made in March 2016 and report right annex absent, rest unchanged. Tumor markers: AFP: 10 ng/ml, Ca125: 10.05 U/mL, Ca19.9: 7.77 U/mL, CEA: 0.69, hCG < 0,100 mIU/mL. For surgical indication, it was known that the staging need to be completed, however we took into account the age and desire to procreate of the patient, the possibility of disease recurrence was explained, and the final decision was a conservative surgical ovarian staging by laparoscopy on April 2016 (peritoneal cytology, bilateral pelvic lymphadenectomy, paraaortic lymphadenectomy, infracolic omentectomy and peritoneum biopsies). Pathology report: multiple biopsies and omentum negative, 0/19 pelvic lymphadenectomy and 0/6 retroperitoneal lymphatics. The clinical stage was IA, and tumor markers were negative after surgery. A multidisciplinary meeting was performed for determinate adjuvant treatment in an early stage case with complementary conservative surgery without active disease. At the time of the present case (2014), our country did not have the SALL-4 study and the decision of chemotherapy was like a germ cell tumor, based on age of presentation and tumor markers.
Began adjuvant chemotherapy at 12 weeks’ post-surgery, with three courses BEP (bleomycin, etoposide and platinum) culminating in November 2016, remaining under observation with negative imaging studies and tumor markers nowadays.
3. Discussion
The first report was in 1987, by Ishikura and Scully (1987), they discovered five cases of ovarian tumors with cytological and morphology characteristics similar to hepatocarcinoma (HCC) without liver commitment. Age of presentation is 35–78 years, over 90% of cases present elevated AFP and Ca 125 can be raised in 60% of cases (Acosta and Pins, 2019).
The diagnosis is mostly in advanced clinical stages (III–IV), <20% of patients have confined disease, and of those cases more than a half progress (Acosta and Pins, 2019). Macroscopically are multinodular, solid tumors, occasionally with cystic component, size between 5 and 35 cm (mean: 12 cm), usually unilateral, but 22% of cases are bilateral (Acosta and Pins, 2019). The association with alpha-fetoprotein (AFP) is over 90%, however, 8% of cases are negative (Sung et al., 2013).
They have been described in various organs, most frequently at gastrointestinal tract (stomach) (Young et al., 1992), also in lungs, gallbladder, pancreas, bladder, kidney, ovaries and uterus. In the genital area, 75% of cases are present in ovary (Cascales Campos et al., 2013), the absence of lesions in the liver parenchyma supports their diagnosis, but the presence of liver and ovarian lesions simultaneously makes the diagnosis very difficult especially when hepatocellular carcinoma rarely metastasizes to the ovary (Young et al., 1992). The median survival is 12 months, between the first and second year is 83% and 53% respectively (Randolph et al., 2015).
Macroscopic general features are tumors with solid and cystic component with white to yellow cut surface; as well as it is common to find hemorrhage and necrosis. Histologic features are a diffuse, trabecular/sinusoidal pattern and nested growth, which often coexist. Also, it can show extracellular hyaline bodies. The cytological features are polygonal cells with moderate to abundant eosinophilic cytoplasm, with distinct cell borders and central round vesicular nuclei with moderate to marked cytologic atypia and some of them with ≥1 nucleoli. Intracytoplasmic hyaline bodies can be observed. Also, frequent mitoses, including atypical forms are observed (Nucci and Oliva, 2018). Inmunohistochemistry features are AFP, Hep-Par1, α-1-antitrypsin, glypican-3, albumin, ck7, ck19 and ck20 positive; while the Pan keratin and CK8 are focally positive; on the other hand, these tumors are negative for calretinin, inhibin, synaptophysin, estrogen receptor and progesterone receptor (Wang et al., 2009). Differential diagnoses are the yolk sac hepatoid tumors that are SALL4 positive, this marker is more sensitive than classical IHC markers, such as placental-like alkaline phosphatase (PLAP), AFP, or glypican3, and strongly stains more than 90% of tumor cells. Positive staining for glypican3, AFP, and PLAP is seen in 100%, 95%, and 66% of cases, which does not occur in hepatoid ovarian carcinoma (Rittiluechai et al., 2014). Another differential diagnosis are metastatic hepatocellular carcinomas that have a multinodular growth pattern; and Steroid cell tumors, which have androgenic manifestations and are smaller cells with vacuolated cytoplasm, positive for inhibin, calretinin, SF1, WT1 (Wang et al., 2009, Rittiluechai et al., 2014).
Thirty-eight cases have been reported, and is still insufficient data to determine optimal treatment of these patients, there is no standard, most patients are treated with surgery (maximum cytoreduction) and adjuvant chemotherapy.
The use of biological therapy extrapolated in relation to hepatocellular carcinoma, sustainable data having little use, since, despite having pathological similarity between HCC and HCO these are biologically different, HCO has clinical aspect in relation to epithelial tumor. In the study by Pandey and Truica (2011) reported the use of sorafenib, and showed no effects in these patients, other reviews mention progression-free survival of 7 months.
We have compiled the reported cases of HCO since 1987 to the present (Table 1), following the sequence performed by Randolph et al., 2015, Acosta and Pins, 2019, having 39 cases including our report. Of all these cases, our patient is the only one how comes out the usual scheme (age of presentation, laparoscopic conservation surgery and adjuvant treatment), she presented AFP 1210 ng/ml, following initial surgery was found in 10 ng/ml and after performing surgery and adjuvant chemotherapy AFP values have remained <7 ng/ml. This case demonstrates that it is possible considerate conservation surgery in an early stage with good outcomes in relation to disease free survival.

4. Conclusions
Hepatoid carcinoma of the ovary is a rare neoplasm, highly aggressive, the most frequent presentation is in perimenopausal and postmenopausal age and usually the diagnosis it’s in advanced disease. The treatment must be optimal cytoreductive surgery followed by chemotherapy. This is the first case reported in our institution and had conservative management. The clinical, imaging and laboratory evolution has been favorable with no evidence of disease relapse at 3 years follow-up.
Author contribution
This case report it’s the first one presented in our country. Being an unusual pathology makes the treatment a challenge, and the presentation of this case is in age range it’s uncommon.
However, radical surgery has been the standard treatment in the cases reported internationally, this is the first case report with different management with conservative surgery under laparoscopic guidance and the disease free survival until now it’s 3 years.
