Squamous cell carcinoma arising from a mature cystic teratoma of the ovary is a rare event representing only 1-2% of all mature cystic teratomas. Furthermore, the synchronous occurrence of a second malignancy in this setting is extremely rare. A 63-year-old woman presented with a pelvic mass which was diagnosed as a left ovarian mature cystic teratoma preoperatively by ultrasonography. The frozen section of the mass revealed a left ovarian mature cystic teratoma with a focus of squamous cell carcinoma. Subsequently surgical staging procedure for ovarian cancer was performed. The final pathologic diagnosis was squamous cell carcinoma in mature cystic teratoma of the ovary, and synchronous endometrial adenocarcinoma with a mixture of endometrioid and mucinous subtypes as an incidental finding. The combination of these two synchronous cancers is unique and to the best of our knowledge, this has not been previously reported in the English language literature. 相似文献

Primary ovarian carcinoid tumors are rare. A 47-year-old woman presented to our emergency room with lower abdominal pain. Physical examination, pelvic ultrasonographic evaluation and abdominal computed tomography revealed a 10-cm mass in the right ovary containing cystic and solid components, as well as calcifications typical of a dermoid cyst. At laparotomy, a smooth-surfaced, firm and mobile right adnexal mass with solid and cystic portions was detected. Initially, right salpingo-oophorectomy was performed. Frozen-section examination identified the mass as a sex cord stromal tumor containing a mature cystic teratoma. Based on this finding, total abdominal hysterectomy, left salpingo-oophorectomy, omentectomy, appendectomy were performed, and the pelvic-paraaortic lymph nodes were also removed. All histological findings in the right ovary were similar to the features of cystic teratoma and trabecular carcinoid tumor. Examination of the resected lymphatic, omental, and appendiceal tissue indicated no tumoral invasion. The diagnosis was ovarian carcinoid Stage IA. Serum testing post-surgery revealed that the levels of cancer antigen (CA) 19-9 and CA125 were 18.5 u/ml and 10.5 u/ml, respectively. The patient was discharged on postoperative day 5. The report describes the clinicopathologic and immunohistochemical features of a primary ovarian carcinoid that contained a mature cystic teratoma. 相似文献

A 30-year-old woman with a history of endometriosis and chronic pelvic pain had right-sided pain and sonographic evaluation demonstrated a right ovarian cyst 5 cm in diameter. Laparotomy revealed a right ovarian cystic mass and the cystic mass was found on the sigmoid colon. After excision, histopathologic study revealed endometrioma for the ovarian cyst and a supernumerary ovary for the cystic mass on the sigmoid colon. 相似文献

The teratoma of the greater omentum is a very rare entity. We present a case of mature cystic teratoma of the greater omentum misdiagnosed as ovarian cyst. The patient was a 36-year-old woman with an omental teratoma of 5 x 4 x 4 cm and an atrophic left ovary. The histopathologic diagnosis was mature cystic teratoma of the greater omentum and no evidence of immaturity or malignancy was noted. Preoperative tumor marker tests revealed moderate elevation of cancer antigen (CA)125, CA19-9 and carcinoembryonic antigen. The left ovary of the patient was atrophic and possible autoamputation of the ovarian tissue might be suggested. 相似文献

BACKGROUND: Mature, benign cystic teratomas of the ovary are common in reproductive-age women, but they are very rarely associated with androgen production and subsequent development of hirsutism or virilization. We describe a case of postmenopausal hirsutism and hyperandrogenism caused by a mature cystic teratoma as well as the 7 previously reported cases. CASE: A 55-year-old, postmenopausal woman presented with hirsutism and unilateral lower extremity edema. Pelvic ultrasound showed a complex cystic mass in the left ovary measuring 6.0 x 7.0 x 10 cm, and laboratory evaluations revealed progressively increasing testosterone levels. The patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy, with resection of a large, complex mass originating in the left ovary. The pathology department found 2 left, mature ovarian cystic teratomas containing a layer of Leydig cells. Postoperatively the patient experienced rapid normalization of the elevated testosterone level. CONCLUSION: Although rare, ovarian production of androgens resulting in hirsutism or virilization can occur with a hormonally active mature cystic teratoma. 相似文献

BACKGROUND: Bone formation in the ovary, with the exception of developing in the setting of mature cystic teratoma, is exceedingly rare. CASE: A 46-year-old woman with a history of endometriosis and chronic pelvic pain underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. A 3 cm solid heavily calcified mass with a stony hard consistency was detected within the right ovary. Microscopic examination revealed extensive calcification of the right ovarian stroma with formation of abundant mature bone, adjacent to small foci of endometriosis. CONCLUSIONS: Endometriosis can be associated with ovarian ossification, forming an extensively calcified adnexal mass. Conservative treatment with close follow-up may be adequate in patients with a history of endometriosis who present with a small heavily calcified ovarian mass and wish to preserve their fertility. 相似文献

Ruptured mature cystic teratoma of the ovary with recurrence in the liver and colon 17 years later. A case report 总被引:2,自引:0,他引:2
A mature cystic teratoma of the ovary occurred in a 51-year-old woman and recurred as a large intrahepatic tumor mass as well as a small mass in the transverse colon 17 years after rupture, intraperitoneal spillage of tumor contents and subtotal surgical removal of the ovarian lesion and peritoneal implants. The patient was treated with a partial hepatectomy and a segmental transverse colectomy. The recurrent lesions, which contained histologically fully mature teratomatous elements only, were excised; the result was a complete cure. To our knowledge this is the first documented report on such a complication of mature cystic teratoma of the ovary. 相似文献

BackgroundGanglioneuromas (GNs) arise from peripheral or central areas of the autonomic nervous system, being benign lesions of neuroblastic origin.CaseA 19-year-old Greek female patient was admitted to our clinic with symptoms of periodic lower abdominal pain and irritation since some months ago. Ultrasonography revealed a mass of 72 × 68 mm originating from the left ovary giving the characteristics of a typical dermoid cyst. Laparoscopic ovarian cystectomy was done. The histological diagnosis revealed a mature cystic teratoma with a small hidden GN.Summary and ConclusionHistology remains the gold standard for their confirmation. The coexistence of GN within a mature cystic teratoma happens extremely rarely. This is one of the few cases reported in the literature. 相似文献

Introduction A feature of multiple spherical structures floating free in a cystic mass is one of the very rare patterns of mature cystic
teratoma.
Case report A 32-year-old unmarried nulligravida was referred. Image diagnosis showed a large cystic tumor with unusual intracystic multiple
floating spherules. Serum tumor marker test showed elevated squamous cell carcinoma antigen. Laparoscopic-assisted left salpingo-oophorectomy
was performed. The histopathological diagnosis was mature cystic teratoma of the ovary with marked desquamative keratin formations.
Conclusions After obtaining pathognomonic findings on diagnostic imaging, laparoscopic management of a rare form of mature cystic teratoma
of the ovary with numerous intracystic floating spherules was successfully performed. 相似文献

Although granulosa cell tumor combined with a dermoid cyst in the same ovary is rarely seen, adult granulosa cell tumor of the ovary with contralateral teratoma has not been reported to date. In this report we present the first case in the English language literature of a ruptured granulosa cell tumor of the left ovary and mature cystic teratoma of the right ovary presenting as acute abdominal syndrome. The patient underwent total abdominal hysterectomy, bilateral-ophorectomy, and multiple pelvic lymph node sampling and infracolic omentectomy. She received combined chemotherapy consisting of bleomycin, etoposide. and cisplatin for six cycles. Subsequent follow-up and workups have revealed no evidence of disease. At 19 months after initial diagnosis, she is disease-free. 相似文献

A 37-year-old postpartum woman was presented with abdominal pain supposed to be caused by uterine involution or puerperal endometritis after vaginal delivery. During the pregnancy, she was suspected to have a subserosal myoma by ultrasound examination. The pain was finally revealed to be originated from the chemical peritonitis caused by the rupture of the mature cystic teratoma of the ovary by Kristeller's maneuver performed during vaginal delivery. When a pregnant or puerperal woman complains about abdominal pain, we need to consider the possibility of chemical peritonitis resulting from the rupture of mature cystic teratoma of the ovary. 相似文献

BACKGROUND: Gangliocytic paraganglioma is a rare neoplasm involving the small intestine, stomach, and spinal cord. Ovarian gangliocytic paraganglioma has not been reported in the medical literature. CASE: A 55-year-old caucasian woman underwent exploratory laparotomy, total abdominal hysterectomy, and bilateral salpingo-oophorectomy for evaluation of a persistent right adnexal mass. Microscopic examination of the right ovary revealed a mature cystic teratoma with a mural nodule consistent with gangliocytic paraganglioma. As there was no evidence of significant pleomorphism or neoplastic infiltration, surgical staging was not performed. CONCLUSION: Gangliocytic paraganglioma may arise from ovarian cystic teratoma. Although most cases of gangliocytic paragangliomas are benign, surgical staging and retroperitoneal lymphadenectomy may be required if histopathology is suggestive of invasive disease or if enlarged lymph nodes are noted. 相似文献

Abstract. Do VT, Thomas GM, Bjarnason GA. Postoperative concurrent chronomodulated 5-fluorouracil/leucovorin infusion and pelvic radiotherapy for squamous cell carcinoma of the ovary arising from mature cystic teratoma.
Primary squamous cell carcinoma (SCC) of the ovary arising from mature cystic teratoma (MCT) is rare. Survival is very poor. Although different postoperative treatments have been tried, none appears to have influenced outcomes. A 44-year-old patient with FIGO stage IIB SCC of the ovary arising in MCT had exploratory laparotomy and left salpingo-oophorectomy, leaving macroscopic residual pelvic disease. Postoperative treatment consisted of a continuous concurrent chronomodulated infusion of 5-fluorouracil 150 mg/m2 /day and leucovorin 10 mg/m2 /day with 5 weeks of pelvic radiotherapy. Three years after initial surgery, she remains disease and complication free. Given this patient's unusually long disease-free survival and the efficacy of concurrent chemotherapy and radiotherapy in other SCCs, the concurrent circadian treatment approach used for this patient should be explored in other cases of SCC of the ovary. 相似文献

A 35-year-old woman presented with long-standing right loin to groin pain and a right ovarian cyst. The ovarian cyst was considered
physiological at the initial gynaecological evaluation. A subsequent transvaginal scan demonstrated a cystic immobile ovary
adherent to the pelvic side wall. Laparoscopy revealed endometriosis and a peritoneal defect holding the cystic ovary against
the ureter and causing compression with secondary loin pain. The trapped ovary was removed and the patient was cured of the
long-standing ureteric colic. This is the first reported case of extrinsic ureteric compression caused by trapped ovary in
a peritoneal pouch associated with endometriosis. The diagnosis was suspected preoperatively from the transvaginal scan findings
demonstrating a cystic immobile ovary adherent to the pelvic side wall. This case demonstrates that in women with unresolved
ureteric compression where adnexal cyst is found, the investigator should look for features that suggest entrapment to the
pelvic side wall. 相似文献

Introduction
Malignant transformation is a rare complication of mature cystic teratoma with squamous cell carcinoma being the most common type. We report a new case of squamous cell carcinoma in situ.Case presentation
A 62 year old woman was admitted for an abdomino-pelvic mass and she underwent a left salpingo-oophorectomy. The histopathologic analysis revealed a squamous cell carcinoma in situ arising in mature cystic teratoma of the ovary. Then, she underwent a total hysterectomy, contralateral salpingo-oophorectomy and omentectomy without adjuvant treatment.Conclusion
Optimal cytoreduction has been associated with a statistically significant improvement in survival for malignant transformation of mature cystic teratoma. 相似文献17.

Malignant transformation of a mature cystic teratoma of the ovary is rare, that of an adenocarcinoma is extremely rare. A 32-year-old woman was suspected as having a malignant transformation of her mature cystic teratoma of the ovary because the preoperative level of carcinoembryonic antigen (CEA) was extremely high. Resections of her ovarian cysts were performed, and this particular tumor was histopathologically diagnosed as an adenocarcinoma arising from a mature cystic teratoma of the left ovary. Because adenocarcinomas arising from mature cystic teratomas of the ovary are extremely rare, we report this case with a review of some of the literature. 相似文献

ObjectiveMature cystic teratomas are mostly confined to the ovaries, but several authors have reported findings of extragonadal occurrences along the migration pathway of primordial germ cells. Extragonadal mature cystic teratomas are extremely rare; their occurrences and pathogenesis are unknown.Case reportWe report the case of a 26-year-old woman who was admitted for scheduled laparoscopic right ovarian tumor excision. An anterior uterine wall mature cystic teratoma and a pararectal corpus luteum cyst were found intraoperatively with coexistence of left adnexal agenesis.ConclusionThe existence of an extragonadal mature cystic teratoma over the anterior uterine serosal layer may be caused by autoamputation and reimplantation as a result of ovarian torsion or displacement of primordial germ cells along their migration path. The existence of an ovarian mass over the sigmoid colon combined with left adnexal agenesis may be the result of ovarian torsion with remnant tissue attached to the sigmoid colon. 相似文献

Introduction The malignant transformation of an ovarian mature cystic teratoma is rare. We presented such a case of a 46-year-old woman with characteristic computed tomography (CT) findings.Case report The patient had suffered from fullness and tenderness of the lower abdomen for one year. A high serum CA-125 level was noted. Computed tomography images showed a left adnexal mass with fat, calcification and soft tissue components, and areas of invasion through the teratoma wall.Outcome The histologic diagnosis was compatible with a squamous cell carcinoma arising from a mature cystic teratoma of the ovary. 相似文献

We present an unusual case in which a 36-year-old patient was referred for consultation due to increasing upper left abdominal pain at 35 weeks' gestation. Transabdominal ultrasonography disclosed an appropriate-for-gestational-age singleton, vertex-presenting fetus with normal anatomy. An unclear, complex, semisolid, semicystic mass was noted in the upper right abdomen. Due to the close proximity of the adnexal mass to the patient's abdominal wall, a high-frequency transvaginal transducer was applied transabdominally. Unlike the unclear images generated at conventional transabdominal ultrasonography, this application depicted a discrete mass with multiple characteristics consisting of calcifications, hair and fatty tissue, considered diagnostic of a mature cystic ovarian teratoma. The patient delivered spontaneously at 39 weeks' gestation. At 6 weeks' postpartum an elective laparotomy left ovarian cystectomy was performed and a mature cystic teratoma confirmed by pathology examination. 相似文献
