Hepatoid variant of yolk sac tumor of ovary is an unusual tumor with an aggressive behavior. It is usually observed in young females, presents with abdominal complaints and is associated with raised α-fetoprotein (AFP) levels. It should be differentiated from other hepatoid tumors involving the ovary. A complete patient evaluation with gross, microscopy, and immunohistochemistry can identify the site of origin to administer appropriate treatment. The current study reported the case of a 30-year-old married parous female presenting with abdominal distention and pain of two months duration. She had regular menstrual cycles. Based on lab investigations her serum AFP level was markedly raised to 34,244 ng/mL (normal range: 0-9 ng/mL). Computerized tomography (CT) scan showed large lobulated heterogeneous mass in both ovaries and omental, gall bladder, and lung metastasis. A CT guided biopsy of the ovarian mass was done. On histopathology, a differential diagnosis of hepatoid variant of yolk sac tumor, hepatoid carcinoma of ovary and hepatoid tumor arising from gall bladder metastasizing to the ovary were observed. Patient underwent surgery. Per operatively gross ascites with bilateral ovarian mass, extensive omental, pelvic, and gall bladder deposits were observed. Bilateral salpingo-oophorectomy with omental deposit biopsy was conducted. Histopathology along with immunohistochemistry confirmed a diagnosis of hepatoid variant of yolk sac tumor in both ovaries with widespread intra-abdominal metastasis.

ysgerminoma is one of the two most common types of ovarian germ cell tumors. Providing accurate pathologic diagnosis and treatment planning, the prognosis is good even in advanced stages. Pathologic diagnosis is generally straightforward. In microscopic examination, the usual known growth patterns in tumor cells are solid, trabecular, insular and rarely pseudoglandular. In this paper, we reported an advanced ovarian dysgerminoma with different microscopic patterns of growth, including pseudopapillary and macrofollicular structures, in an 18-year-old woman. The patient underwent staging laparotomy and is currently receiving chemotherapy.

Ovarian small cell carcinoma is a rare and highly malignant tumor with poor prognosis. It usually presents in younger females with features of hypercalcemia. The exact histogenesis of the tumor is unclear and it may present as an undifferentiated tumor. In such cases, immunohistochemistry (IHC) plays an important role to confirm the diagnosis. Limited treatment options are available and mainly include radical surgery followed by adjuvant therapy in advanced stages. The current report was a rare case of small cell carcinoma of ovary presenting no symptoms of hypercalcemia diagnosed on histopathological examination and IHC findings.

Abstract
Placental mesenchymal dysplasia (PMD) is a rare benign placental abnormality. It is characterized by hydropic degeneration of stem villi, placentomegaly, and increased maternal serum alpha-fetoprotein(AFP). It can be associated with different congenital abnormalities, karyotype abnormalities, and feto-maternal ...

Placental mesenchymal dysplasia (PMD) is a rare benign placental abnormality. It is characterized by hydropic degeneration of stem villi, placentomegaly, and increased maternal serum alpha-fetoprotein(AFP). It can be associated with different congenital abnormalities, karyotype abnormalities, and feto-maternal morbidities. It is difficult to differentiate PMDfrom partial mole, complete mole with twin pregnancy in ultrasound, and in macroscopic examination. The current paper presentsa rare case of placental mesenchymal dysplasia in a young primigravida mother who delivered a normal fetus withnormal karyotype.

Background & objective: The HER-2 gene is an important on co protein overexpressed in many types of cancers. The current study hypothesized that curcumin downregulates HER-2 and inhibits the signal transduction pathway of PI3K/Akt, MAPK, and activation of NFκB, which could be useful to treat overexpressed-HER-2 hepatocellular carcinoma (HCC). Methods: In the current study, 40 male NMRI (Naval Medical Research Institute) mice were divided into 4 groups of 10 as follow: Group1 (control group) only received 5 mL/kg corn oil, group 2 (poisoned group) received 30 mg/L arsenic (As2O3) dissolved in water, group3 (curcumin treated), and group 4 (curcumin and arsenic treated) received 10 to 20mg/5mL/kg for 60 days. Once experimental period was completed, liver samples were collected. The analysis of the gene expression was performed by real-time polymerase chain reaction (PCR) technique. Results: Gene expression analysis showed that curcumin had significantly downregulated the activity of HER-2, in poisoned mice. Conclusion: According to the current study results, it could be concluded that curcumin has the inhibitory potential toward HER-2-overexpressed HCC.

Giant Cell Fibroma (GCF) was described as a new entity of fibrous hyperplastic soft tissue. It seems that stimulus from an unexplained origin can have a role in its etiology. Histopathologically GCF is consisted of multinucleated fibroblasts that have oval shape nuclei within the eosinophilic cytoplasm. Surgical excision is the treatment of choice and recurrence is very rare. Here we report a case of relatively large GCF in a 54-year-old man. Gingiva is the common location of GCF. As in our case, it may be mistaken as irritation fibroma especially if it is on the buccal mucosa, the most common location for fibroma. Correct diagnosis is based on biopsy and clinical examination to see surface texture roughness. To minimize bleeding because of its large size an excisional biopsy with Diod laser was performed under local anesthesia for this patient.
