原始神经外胚层肿瘤(primitive neuroectodermal tumor,PNET)分为中枢型和外周型,外周型PNET属于尤文肉瘤家族肿瘤,其发生是由于基因调控失常,原始干细胞向神经上皮各不同阶段分化,成为形态上类似于儿童中枢神经系统的肿瘤,其组织学及临床生物学行为类似于骨外的尤文肉瘤。卵巢原发PNET为外周型PNET,属于卵巢单胚层畸胎瘤,极为罕见,疾病早期即可发生转移、容易复发,预后极差。其临床表现缺乏特异性,患者常以腹痛、腹胀、盆腔包块就诊,病理是诊断的金标准。目前无明确诊治指南,国内外相关文献多为病例报道,1975—2017年英文文献报道的原发于卵巢的PNET仅17例。本文报道4例我院诊治的卵巢原发PNET,同时复习相关文献,描述此种罕见疾病的临床表现、治疗方法及预后情况。  相似文献

Purpose  

Ewing’s sarcoma (ES) and primitive neuroectodermal tumor (PNET) are closely related malignant neoplasms, usually affecting the skeletal system. Extraosseous ES/PNETs are uncommon, with occasional reports of tumors affecting the genitourinary tract. Only few cases of primary vulvar Ewing’s sarcoma/PNET have previously been reported.  相似文献

Purpose

This review presents the information about epidemiology, clinical manifestation, diagnosis and treatment of primary ovarian Burkitt’s lymphoma (BL), including a literature search of available BL cases. The purpose of this review is to draw clinicians’ attention to the possibility of ovarian BL occurrence, which may be important in the differential diagnosis of ovarian tumours.

Methods

PubMed and Web of Science databases were searched using the keywords ‘‘Burkitt’s’’, ‘‘Lymphoma’’, ‘‘Ovarian’’, ‘‘Primary’’, ‘‘Burkitt’s lymphoma’’. Only cases with histopathologically confirmed diagnosis of primary ovarian BL were included in this review.

Results

Fifty articles, reporting cases with an ovarian manifestation of primary non-Hodgkin’s lymphoma, were found. Twenty-one cases with a histopathologically confirmed BL were evaluated to compare various manifestations, treatment and prognosis in ovarian BL.

Conclusions

Primary ovarian BL is a rare condition, included in the entity of non-Hodgkin lymphoma. The tumour can occur uni- or bilaterally in the ovaries with major symptoms such as abdominal pain or a large abdominal mass. Differential diagnosis, based on imaging features and pathological examination of the specimens, is essential for further treatment due to various aetiology of ovarian tumours. Although most of the patients suffering from ovarian BL underwent surgery after the ovarian tumour had been detected, surgical treatment is not the treatment of choice in patients with ovarian lymphoma. The mainstay of therapy is chemotherapy without further surgery. The prognosis is better if the chemotherapy protocol is more aggressive and followed by prophylactic central nervous system chemotherapy. Nowadays, multiagent protocols are administered, which improves the survival rate.

Leiomyosarcomas of the ovary and broad ligament are relatively rare. Less than 50 cases of primary ovarian and broad ligament leiomyosarcomas have been reported. The prognosis is poor, with late-stage disease being a problem in the majority of cases. It is difficult to determine the exact role of surgery, chemotherapy, and radiotherapy in the management of these tumors. So far, no cases of ovarian or broad ligament leiomyosarcomas have been reported where primary surgery for the sarcoma had to be combined with a Palma's procedure. We report a case of a right pelvic sidewall leiomyosarcoma with involvement of 10 cm of the right external iliac vein. A review of the imaging preoperatively did not suggest involvement of the venous system. Resection of the pelvic mass was carried out and a Palma's procedure was performed by the vascular surgeon. Histology reported an incompletely excised high-grade leiomyosarcoma. Chemotherapy was given postoperatively. Imaging at 12 months after surgery showed a patent vascular graft and no evidence of recurrence. There was no clinical evidence of recurrence at 21 months postsurgery.  相似文献

子宫肉瘤是发生于女性生殖器官的恶性肿瘤,其发病率低、预后差,主要有异常阴道出血、腹痛、腹部包块等临床表现。血清乳酸脱氢酶、血清中性粒细胞与淋巴细胞比值(NLR)等血清学指标及超声和磁共振成像等影像学检查可协助子宫肉瘤的术前诊断,但目前其诊断仍主要依靠术后病理结果。子宫肉瘤主要有子宫平滑肌肉瘤、子宫内膜间质肉瘤及子宫腺肉瘤3种病理类型。全子宫及双附件切除是标准手术方式,术后可根据不同病理类型及手术分期选择辅助治疗方式。通过查阅国内外文献,综述子宫肉瘤的临床表现、辅助检查、病理特征、治疗及预后等。  相似文献

BACKGROUND: In recent years, true primary ovarian lymphoma has been considered to carry a favorable prognosis, although most studies of supposedly primary ovarian lymphoma have reported a poor outcome. CASE: A 47-year-old woman presented with signs and symptoms suggestive of an advanced ovarian cancer. Ultrasonography and magnetic resonance imaging revealed bilateral abdominal tumors, each measuring 10 cm in diameter, thickened omentum, and a large amount of ascitic fluid, but no enlarged lymph nodes. The diagnosis of malignant lymphoma was established from the biopsy specimen after exploratory laparotomy. Six years following chemotherapy, the patient is alive and disease free without additional surgery. CONCLUSION: The prognosis of ovarian lymphoma was evaluated according to clinical stage, modality of onset, histologic type, and phenotype. It remains controversial whether this case can be considered truly primary ovarian lymphoma and not merely a localized initial manifestation of a generalized disease. But if this case of advanced ovarian lymphoma were not primary, it could still be managed successfully with chemotherapy appropriate for the specific histology.  相似文献

Pseudomyxoma peritonei (PMP) is a rare condition, said to be more common in females during the fourth or fifth decade of life with an incidence believed to be in the region of one per million per year. Although PMP has been reported as originating from many intra-abdominal organs, in the majority of cases an ovarian or appendix cystadenoma or cystadenocarcinoma has been implicated as the primary site. Our experience suggests that most cases arise from the appendix. We have reviewed the clinical and scientific evidence. In the four largest reported series of 393 patients, 181 (46%) were males. Immunohistochemistry techniques in women with both appendical and ovarian tumours favour an appendiceal primary in most cases. The distinction between "benign" adenomucinosis and mucinous adenocarcinoma is important in both treatment and prognosis. Experience suggests that there may well be a spectrum of disease and possibly an "adenoma carcinoma sequence".  相似文献

BACKGROUND: Primary ovarian angiosarcoma is a very rare gynaecologic malignancy with poor prognosis and uncertain, up-to-date, treatment options. Its exact diagnosis is challenging for surgeons and difficult for pathologists. There are only a few cases reported in the international literature. CASE: We report a case of primary pure ovarian angiosarcoma with coexisting chylothorax which is, to the best of our knowledge, the first reported case. An extensive review of the literature analyzing all clinical and pathological parameters related to this condition is presented. RESULT: In spite of all therapeutic efforts, surgical and medical, prognosis of ovarian angiosarcoma remains very poor in most cases. CONCLUSION: Primary ovarian angiosarcoma is a rare and aggressive malignancy. The report of such cases is interesting in order to exchange knowledge and experience, and possibly to further improve our diagnostic and therapeutic capabilities.  相似文献

OBJECTIVE: To determine the frequency of synchronous primary neoplasia of the ovaries in patients with primary malignant neoplasia of the uterus, and to analyze the clinical and histological characteristics of these cases. MATERIALS AND METHODS: Clinicopathological data from a series of patients treated for primary malignant neoplasia of the uterus between 1985 and November 2003 have been studied retrospectively. RESULTS: Synchronous primary neoplasia of the ovaries was found in 13 out of 173 patients (7.5%) treated for primary malignant neoplasia of the uterus. In four patients (2.3%) the histological findings suggested ovarian metastases from primary endometrial adenocarcinoma. In four other cases (2.3%) there was extension of the primary uterine sarcoma to the ovaries. In the remaining five cases (2.9%) primary endometrial adenocarcinoma coexisted with: a) ovarian cystadenocarcinoma in two cases, b) ovarian fibromathecoma in two cases, and c) ovarian tumor of borderline malignancy in one case. CONCLUSIONS: Coexistence of distinct primary neoplasias in the uterus and ovaries is rare. Diagnosis of two primary malignancies in the uterus and ovaries should be based on histological examination. Treatment should be appropriate for both tumors, taking into consideration that treatment of one tumor will not lead to subtreatment of the other.  相似文献

Ovarian cancer is considered the leading cause of death among gynecologic neoplasias. Breast metastases from primary ovarian cancer have been reported in only 0.03–0.6% of all breast cancers. A 38-year-old female, multipara, affected by advanced ovarian cancer and undergone a total abdominal hysterectomy with bilateral salpingo-oophorectomy, omentectomy, and pelvic peritonectomy two years earlier, was discovered to have a breast metastasis. She underwent a quadrantectomy (QSI) with an open biopsy of nodularity attached to the pectoral muscle fascia: on definitive histological characterization the breast lesions showed a high-grade invasive carcinoma, with papillary serum differentiation, and the immunohistochemistry study of breast lesion showed positivity for cytokeratin 7 and an extensive positivity for Wilm’s tumor (WT)-1 and paired box 8 (PAX8). These aspects are indicative of mammary metastasis from carcinoma of ovarian origin. Despite their rarity, metastases to breast from ovarian cancer should be considered possible because their recognition and differentiation compared to primary tumors are crucial for prognosis. Future clinical studies on MOCB should be performed to discover new specific markers for a more accurate histopathological diagnosis and to establish the real need of surgical treatment.  相似文献
