RESUMO

This is a case report of a 10-year-old with Ollier disease and an ovarian mass. Ollier disease, a rare disorder characterized by multiple enchondromas resulting in bone deformities, has been occasionally associated with ovarian juvenile granulosa cell tumor. This patient developed signs of precocious puberty and was found to have an ovarian tumor; however, pathology revealed a mixed sex-cord stromal tumor with components of juvenile granulosa and Sertoli-Leydig cell tumor. Tumor genomic testing revealed an IDH1 mutation. Mixed sex-cord stromal tumors of this type, also called "gynandroblastomas," have been associated with DICER1 mutations and DICER1 tumor predisposition syndrome but never with Ollier disease. Our findings expand the known spectrum of syndromic associations with this tumor type, with implications for tumor screening.

RESUMO

RATIONALE: Leiomyomas are the most common benign tumors of smooth muscle origin in women. They are most frequently found in the submucosal tissue of the uterine corpus; however, they also occur in other areas of the uterus, including the cervix. Their size usually varies between 0.5 to 1.0 cm; however, they can reach great dimensions. A strong correlation between the onset and growth of leiomyomas and estrogen levels was observed. Granulosa cell tumor (GCT) is an infrequent sex cord-stromal ovarian neoplasm. Despite their malignancy, GCTs have a good long-term prognosis. In this study, we present a unique case of coincidence of 2 tumors: leiomyoma of rare location (cervix uteri) and extraordinary size (9, 04 cm diameter) with an adult granulosa cell tumor. PATIENT CONCERNS: A 67-year-old Caucasian woman was transported from an emergency ward to a gynecological surgery department due to a massive vaginal hemorrhage. DIAGNOSES: Preliminary examination showed a presence of an enormous uteri cervix tumor. INTERVENTIONS: Initially, the patient underwent physical and ultrasound examinations. To prevent further bleeding, an urgent surgery (hysterectomy) with bilateral salpingo-oophorectomy was performed. OUTCOME: Postoperative histopathological examination revealed a cervical leiomyoma and the incidental occurrence of an adult GCT in the right ovary. LESSONS: This case shares an interesting coincidence between a rare variant of leiomyoma and GCT. The study suggests that the potential reason for this can be estrogen secreted by the GCT, which causes the enormous size of the patient's cervical leiomyoma and the severe vaginal bleeding. Therefore, we advise it is important in abnormal cases to search for other hidden explanations, as in cases of GCT.

RESUMO

BACKGROUND Juvenile-type granulosa cell tumors (JGCTs) are a rare subtype of sex cord stromal tumor with a characteristic histology that is commonly found in the first 3 decades of life. It most commonly presents with symptoms of hyperestrogenism, which may present as precocious pseudopuberty or as menstruation-related symptoms, allowing for early detection of the tumor. CASE REPORT We present the case of a 12-year-old girl who presented to her primary care provider (PCP) with secondary amenorrhea with intermittent abdominal pain, who underwent an ultrasound for further evaluation, which revealed a large incidental pelvic mass. She was admitted to the Emergency Department (ED) and had findings of galactorrhea and hyperprolactinemia on examination. Imaging studies demonstrated a large ovarian mass measuring 15.0×9.0×18.8 cm that was resected, and subsequent pathology results showed JGCT stage 1A. CONCLUSIONS Prognosis of granulosa cell tumors (GCT) largely depends on its initial size, stage at diagnosis, residual tumors after surgery, and the subtype of GCT. If the patient is of reproductive age, fertility-sparing surgical options must be considered and patients must be regularly monitored for recurrence. JGCTs can present with minimal to no symptoms of precocious puberty in young girls but may present with amenorrhea, which may be considered normal for their developmental age. Although JGCTs are rare, they are important to include in differential diagnoses of younger female patients with abdominal pain, especially if accompanied by hormonal irregularities.

RESUMO

Prior case reports have described synchronous ovarian juvenile granulosa cell tumor (JGCT) and enchondromatosis in patients with Ollier disease and Maffucci syndrome. We present a case of a juvenile granulosa cell tumor with an IDH1 somatic mutation identified in the ovarian tissue in a 15-year-old female who presented with abnormal vaginal bleeding, several months of irregular menses, and a large multicystic adnexal mass. Multiple mixed lytic and sclerotic lesions were identified in the bones of the pelvis on imaging studies obtained during the work-up of her abdominal mass. Like previous reports in patients with undiagnosed enchondromatosis, these lesions were presumed to represent skeletal metastases; however, biopsy tissue revealed a hyaline cartilage neoplasm. Subspecialty review of the imaging findings revealed imaging features classic for Ollier disease involving the flat bones of the pelvis. It is important for radiologists to be familiar with the association between enchondromatosis and JGCT. When a female patient with enchondromatosis presents with a large, unilateral, mixed solid-cystic ovarian mass, the diagnosis of JGCT can be suggested. Alternatively, when a patient is diagnosed with JGCT, any skeletal lesions should be scrutinized for imaging features that suggest a hyaline cartilage neoplasm to avoid the misdiagnosis of skeletal metastases in a patient with previously undiagnosed Ollier disease or Maffucci syndrome. To our knowledge, this is the second reported confirmed case of an IDH1 somatic mutation identified in the ovarian tissue of a JGCT in a patient with Ollier disease.

RESUMO

Aim: To present the clinicopathologic findings of the second case of androgen-secreting adult granulosa cell tumor (AGCT) in a woman with polycystic ovary syndrome (PCOS) and discuss in the light of the literature. Methods: Description of a case and discussion of the literature. Results: A patient with oligomenorrhea, amenorrhea and hirsutism who was diagnosed as PCOS and treated by oral contraceptive for three years, then left ovarian solid and liquid mass was found and pathologically confirmed to be androgen-secreting AGCT after left oophorectomy. She got regular menstrual cycle and gave birth naturally, but clinical features of PCOS reappeared after breastfeeding. Conclusion: Androgen-secreting AGCT and PCOS have similar clinical features of hyperandrogenism, it is difficult to diagnose androgen-secreting AGCT when both diseases occur in the same patient. If the size of cystic mass in androgen-secreting AGCT is too small to differentiate from PCOM on imaging, pathological examination after surgery may be the only way to find the disease.

RESUMO

Juvenile granulosa cell ovarian tumor is a rare cause ofpseudo-precociouspuberty. We report a case of a 6-year-old female with neurofibromatosis type 1 (NF1), associated with pseudo-precocious puberty (PPP). A thorough workup revealed a large multi-cystic right ovarian mass, which turned out to be a juvenile granulosa cell tumor (JGCT). This report documented a rare case of PPP caused by JGCT in a child with NF1. Verbal consent was taken from the family.

RESUMO

Estrogen modulates platelet activation and aggregation, and it increases the levels of the von Willebrand factor, factors II, VII, VIII, and X, and of fibrinogen, all of which increase the risk for thromboembolism. We report the case of a 59-year-old woman, postmenopausal for 4 years, not using hormone replacement therapy, who was admitted into the emergency room with shortness of breath and increased abdominal volume. After physical examination and imaging and biochemical tests, she was diagnosed with pulmonary thromboembolism and a large left adnexal tumor. The patient was promptly received full anticoagulation therapy for the pulmonary thromboembolism. High levels of estradiol (810.4 pg/mL), anti-Mullerian hormone (16.39 ng/mL), inhibin (11250 pg/mL), and suppressed FSH (<0.16 IU/L) led to a suspicion of granulosa-cell tumor. After clinical stabilization, she underwent to an exploratory laparotomy with total hysterectomy and bilateral adnexectomy to treat the pelvic tumor. Pathologic report confirmed a granulosa-cell tumor.

RESUMO

BACKGROUND: Ovarian granulosa cell tumor (GCT) is extremely rare in children and adolescents, especially along with Meigs syndrome (MS). CASE: We describe the case of a 12-year-old girl who was referred to our center for massive peritoneal effusions with evidence of a pelvic mass on ultrasonography and computed tomography. The patient was treated with laparoscopic surgery (fertility-sparing surgery) and postoperative chemotherapy. SUMMARY AND CONCLUSION: Our case highlights the clinical importance of assessing MS in the diagnosis of pediatric female patients with peritoneal effusion and ovarian mass and the importance of fertility-sparing surgery.

RESUMO

Ovarian causes of precocious pseudo-puberty (PPP) include McCune-Albright syndrome (MAS) and juvenile granulosa cell tumour (JGCT). We describe a case of PPP in which bilateral ovarian enlargement with multiple cysts progressed to unilateral JGCT. A girl aged 2.17 years presented with three months of breast development, and rapid growth. Examination showed tall stature, height +2.6 standard deviations, Tanner stage B3P2A1. A single café au lait patch was noted. Bone age was advanced at 5 years. Pelvic ultrasound showed bilaterally enlarged ovaries (estimated volumes 76 mL on the left, 139 mL on the right), each containing multiple cysts. Luteinizing hormone (LH) and follicle stimulating hormone (FSH) values before/after gonadotrophin administration were 0.43/0.18 and <0.1/<0.1 mUI/mL, serum estradiol 130 pg/mL, (prepubertal range <20 pg/mL). PPP of ovarian origin was diagnosed, and tamoxifen 20 mg daily started. However, after only seven weeks height velocity escalated and breast development increased to B3-4 with menorrhagia. Basal/stimulated LH and FSH were still suppressed at 0.13/0.25 and <0.1/<0.1 mUI/mL and, serum estradiol 184 pg/mL. Repeat imaging now showed normal right ovary (volume 1.8 mL) and a large left-sided vascular solid/cystic ovarian tumour which was excised (weight 850 g). Histology showed JGCT, International Federation of Gynecology and Obstetrics stage IA. DNA from tumour tissue showed no mutation in GNAS, exon 3 of AKT1 (which contains a mutational hotspot) or FOXL2. The observation that bilateral ovarian activity progressed to unilateral development of JGCT in this patient is novel. This case highlights current uncertainties in the ontology of JGCT, and its possible relationship with MAS.

RESUMO

OBJECTIVE: Adult-type granulosa cell tumors (GCT) are sex cord-stromal tumors and often accompanied with abdominal distention and hyperestrogenism-related symptoms. Adult-type GCT-presenting ascites and pleural effusion is extremely rare. CASE REPORT: A 56-year-old perimenopausal woman presented with abdominal distention and abnormal vaginal spotting. Ultrasound and abdominal computed tomography showed a complex cystic mass in the left ovary accompanied with bilateral pleural effusion and ascites. The patient underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, left pelvic lymph node dissection, omentectomy and appendectomy. Final histopathological diagnosis was adult-type GCT. The patient had postoperative hormone and anti-angiogenesis agent therapy with free of disease. CONCLUSION: Ovarian cystic complex mass accompanied with ascites and pleural effusion often results from malignant ovarian tumors or benign ovarian fibroma. Based on the aforementioned report, the rare types of ovarian tumors, such as adult-type granulosa cell tumor of the ovary should be taken into consideration.

RESUMO

Juvenile ovarian granulosa cell tumors (JGCTs) are described infrequently in pediatrics, and their finding in infants is exceptional. We highlight the presenting symptoms, radiologic images, operative management, and histopathologic findings of a 9-month-old female with isosexual pseudopuberty. An updated revision of literature in infants below the age of 12 months is also reported.

RESUMO

Ovarian adult-type granulosa cell tumors are often associated with endometrial hyperplasia or even uterine cancer. Herein, we present a case report of a 65-year-old female patient who had undergone curettage of the uterine cavity several times due to abnormal and irregular uterine bleeding. Owing to recurrent episodes of vaginal bleeding as well as ineffective pharmacological treatment of simple endometrial hyperplasia without atypia, the patient underwent a laparoscopically-assisted vaginal hysterectomy. Owing to an enlarged right ovary with bluish color, intra-operative pathological examination was immediately performed. Surprisingly, an ovarian adult-type granulosa cell tumor was diagnosed, and the surgery was extended to pelvic lymphadenectomy and omentectomy. Immunohistochemical staining with selected antibodies (Arginase 2, Nidogen 2, BAF250a/ARID1A, GPR30, SF-1/NR5A, and 1LRH-2E1/NR5A2) was also performed. In conclusion, in cases of recurrent vaginal bleeding concomitant with endometrial hyperplasia, the existence of rare ovarian tumors connected with extensive estrogenic stimulation must be taken into account. Immunostaining with selected antibodies (Arginase 2, Nidogen 2, ARID1A, or GPR30) may help elucidate the possible molecular mechanisms associated with the BAF250a/development of various ovarian/endometrial abnormalities.

RESUMO

Juvenile granulosa cell tumor (JGCT) is an extremely rare ovarian tumor that has been associated with Maffucci syndrome. It both secretes hormone and has been postulated to grow in response to hormone. We present a case of a 33-year-old G1P0 asymptomatic woman with a history of Maffucci syndrome found to have a left adnexal mass on routine ultrasonography at 13 weeks gestation. This case demonstrates the sonographic and magnetic resonance imaging (MRI) features of JGCT, as well as the natural progression of the tumor during pregnancy. A follow-up ultrasound 3 weeks after initial diagnosis demonstrated marked growth in size and vascularity of the tumor, prompting unilateral salpingo-oophorectomy. Histopathological findings confirmed the diagnosis of JGCT.

RESUMO

Juvenile granulosa cell tumors of the ovary are rare sex cord-stromal ovarian tumors that are typically diagnosed during the first 2 decades of life. Most patients present with precocious puberty in the early stages of disease. We present a rare case of asymptomatic uterine torsion from a 15-cm juvenile granulosa cell tumors in a 5-year-old girl with elevated inhibin B, breast development, vaginal bleeding, and a palpable right-sided abdominal mass.

RESUMO

The case of a 36-yr-old woman with a pituitary adenoma who was found to have bilateral ovarian masses is reported. The right ovary was removed, measured 15 cm in maximum dimension, and contained multiple cysts which on microscopic examination had the typical morphology of follicle cysts. The left ovary was grossly similar intraoperatively. Subsequent excision of the pituitary adenoma was followed ∼3 mo later by a return to normal size of the left ovary. The case represents an example of multiple luteinized follicle cysts, analogous to the phenomenon seen occasionally in pregnancy, but with a different clinical background. Periodic documentation of this phenomenon is present in the literature, predominantly the clinical literature with limited pathologic documentation of the nature of the process in many reports. As pertains to the evaluation of follicle cysts encountered during pregnancy the differential diagnosis is with a cystic granulosa cell tumor of either adult or juvenile types, more likely the latter. The cyst lining is identical to that of standard follicle cysts and contrasts with the immature mitotically active nuclei seen in a juvenile granulosa cell tumor. That neoplasm also usually shows follicular differentiation typically absent in follicle cysts. Pathologists should be aware of the rare occurrence of luteinized follicle cysts in patients with a pituitary adenoma to enable correct intraoperative and standard pathologic evaluation.

RESUMO

Resumen Introducción: Los tumores de las células de la granulosa de tipo juvenil (TCGJ) son muy poco fre cuentes, especialmente en menores de 1 año. Los signos de pubertad precoz constituyen la presenta ción clínica más importante. Objetivo: Presentar una lactante con pubertad precoz periférica, con diagnóstico de TCGJ, discutiendo las claves de su tratamiento y seguimiento. Caso Clínico: Lactante de 10 meses que presentó telarquia, vello púbico y tumor abdominal palpable acompañado de niveles plasmáticos de Estradiol aumentados, gonadotrofinas muy bajas e imágenes que mostraban masa ovárica gigante. Se realizó salpingooforectomía, obteniéndose regresión absoluta de signos y síntomas. La biopsia demostró TCGJ por lo que se tomó inhibina B (InB) como marcador después de la cirugía. Esta hormona estaba alta inicialmente, pero descendió rápidamente. El seguimiento se basó en InB, Hormona antimulleriana (AMH) y estradiol como se describe en este tipo de tumores. Conclusiones: Los TCGJ son muy infrecuentes en pediatría; deben sospecharse en niñas con puber tad precoz periférica. El tratamiento quirúrgico en la gran mayoría es curativo, pero debe mantenerse un estricto control con marcadores tumorales, siendo los más específicos la InB y la AMH y en menor escala los niveles de Estradiol.


Abstract Introduction: Juvenile granulosa cell tumors (JGCT) are very rare, especially in infants under the age of one. The most frequent presentation is with signs of precocious puberty. Objective: Present an in fant with peripheral precocious puberty, diagnosis of JGCT and follow up. Clinical case: 10-month-old female infant with thelarche, pubic hair and palpable abdominal mass accompanied with eleva ted levels of estradiol, very low gonadotrophins and images that show a very large ovarian mass. A sapingooforectomy was carried out with full regression of symptoms and signs and improvement of laboratory exams. The biopsy showed TCGJ so inhibin B (InB) was taken as tumoral marker after surgery. This hormone was high initially, but rapidly declined. Follow-up was based on InB, antimu-llerian Hormone (AMH) and estradiol as described in this type of tumors. Conclusions: Juvenil gra nulosa cell tumors are very infrequent in pediatric age, but should be suspected in girl with peripheral precocious puberty. The majority of cases improve with surgery, but strict surveillance of tumoral markers is needed. The most specific markers are inhibin B and anti mullerian hormone (AMH), followed by estradiol levels.
