Gonadoblastoma is a rare ovarian neoplasm which belongs to "germ cell-sex cord-stromal tumor" category. This tumor is frequently associated with invasive germ cell malignancy. It commonly arises in dysgenetic gonads of young individuals who are phenotypically females but possess 46XY karyotype. It has been rarely reported in females with normal phenotype and genotype. We herein describe a case of 10-year-old female who presented with abdominal pain, abdominal distention and fever. CT scan of the abdomen and pelvis revealed bilateral ovarian masses, ascites and pelvic and para-aortic lymphadenopathy. Serum lactate dehydrogenase levels were also elevated. She underwent left salpingo-oophorectomy, right ovarian biopsy, omentectomy and para-aortic lymphadenopathy. Microscopically, tumor showed in situ and invasive components. In situ component was arranged in nests and lobules formed by immature sertoli cells forming acini and encircling large polygonal primitive germ cells. Immature sertoli cells were positive for immunohitochemical (IHC) stains cytokeratin AE1/AE3, inhibin and calretinin, while germ cells were positive for SALL4, Oct 3/4, placental alkaline phosphatase (PLAP) and CD117. Invasive component was arranged in sheets of large-sized, polygonal-shaped primitive germ cells which were also positive for SALL4, Oct 3/4, PLAP and CD117 IHC stains. Hence, the diagnosis of "gonadoblastoma with dysgerminoma" was made. The tumor was limited to both ovaries. Cytogenetic analysis of peripheral blood revealed normal female 46XX karyotype. The patient received two cycles of adjuvant chemotherapy and was then lost to follow-up. We conclude that gonadoblastoma, although rare, should be considered as a differential diagnosis in ovarian tumors of young females. Invasive germ cell component should always be carefully searched for as it guides about treatment and predicts prognosis.
Nipple adenoma (NA) is a rare benign breast neoplasm that seldom co-exists with breast carcinoma (BC). Majority of these BC are separate from NA, and their origin from NA is an extremely rare event. We herein describe a case of 65-year-old female who had a painless lump for 15 years which increased in size and ulcerated for last six months. Microscopic examination of the wedge biopsy of nipple showed features of NA at superficial aspect and invasive carcinoma from it at the deeper aspect. The patient underwent mastectomy and axillary clearance, which revealed a 4-cm invasive breast carcinoma, no special type with axillary lymph node involvement. The patient received adjuvant chemotherapy, radiotherapy and adjuvant hormonal therapy. The patient is alive and disease-free after 36 months. NA should be carefully evaluated for co-existent BC because it completely changes the treatment plan and prognosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
