1/44. Sarcoma botryoides of the cervix. Report of a case with cytopathologic findings.BACKGROUND: Cytologic findings of sarcoma botryoides were still equivocal because sarcoma botryoides of the uterine cervix is an extremely rare neoplasm, and few cases have been reported to date. CASE: A 17-year-old female was diagnosed with sarcoma botryoides of the uterine cervix. The entire vaginal canal was occupied with polypoid masses, which arose from the anterior lip of the uterine cervix, and the tumor was classified as group I (Intergroup rhabdomyosarcoma Study). After wedge resection and six courses of combination chemotherapy, the tumor recurred in the same location of the cervix as the primary lesion. touch smear of the polypoid mass formed loose clusters and also showed short spindle cells in a necrotic background. The nucleus of the tumor cells had a thin nuclear membrane, fine chromatin pattern and partly clear nucleolus, showing mild nuclear atypia. Immunohistochemically, some of the tumor cells showed positive staining for myoglobin and desmin. CONCLUSION: The cytologic findings of sarcoma botryoides of the female genital tract are typical features of nonepithelial malignant tumor. Immunohistochemical study is useful for the diagnosis of rhabdomyosarcoma.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
2/44. Pseudovascular squamous cell carcinoma of the uterine cervix: a lesion that may simulate an angiosarcoma.A case of pseudovascular squamous cell carcinoma in the uterine cervix of a 64-year-old woman was examined. Histologically, the lesion consisted of atypical, large, non-keratinizing squamous cells that exhibited not only acantholytic changes but also pseudovascular changes. Immunohistochemically, these tumor cells were positive for cytokeratin, epithelial membrane antigen and carcinoembryonic antigen, but none of them were positive for factor viii-related antigen or CD34. To our knowledge, pseudovascular carcinoma of the uterine cervix has not been described in the literature. Pathologists should be aware of this unusual form of cervical squamous cell carcinoma, particularly in the differential diagnosis of angiosarcoma.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
3/44. Peripheral primitive neuroectodermal tumour of the cervix.Peripheral primitive neuro-ectodermal tumours (PNET) of the cervix are very rare. Here, we report the clinical, pathological, immunohistochemical and genetic features of a case of a PNET located in the cervix. hysterectomy revealed a cervical tumour. On microscopic examination, a vaguely lobular arrangement of uniformly appearing neoplastic cells, with round to oval nuclei, distinct nuclear membranes and a clear, moderately glycogen-rich cytoplasm was seen. cells stained positive for LEU 7, S 100, monoclonal NSE and particularly for MIC2. Neurogenic differentiation was also seen by electron microscopic examination. The genetic hallmark of PNET, a 22q12 rearrangement was demonstrated by fluorescence in situ hybridisation experiments, supporting the diagnosis. awareness of the existence of primary PNET of the cervix is important to avoid confusion with other tumours of the cervix.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
4/44. basement membrane material and tigroid background in a fine needle aspirate of clear cell adenocarcinoma of the cervix. A case report.BACKGROUND: Although cytologic findings of clear cell adenocarcinoma of the female genital tract have been reported sporadically, the background on the smear has received little attention. CASE: A 16-year-old female had a large, necrotic mass in the cervix. As cervical brushing cytology and a punch biopsy of the mass could not make a definitive diagnosis, fine needle aspiration cytology was performed from the mass. The smears revealed loose, three-dimensional clusters and sheet arrangements of atypical cells. Dispersed atypical cells were also seen. The atypical cells were large and had abundant, weakly stained cytoplasm and round or oval nuclei with large nucleoli. There were a few tumor cells with clear cytoplasm and distinct cell borders in Papanicolaou-stained smears. The background in Diff-Quik-stained smears revealed a tigroid background and basement membrane material. CONCLUSION: The malignant tumor, revealing both a tigroid background and basement membrane material, seems to have been clear cell adenocarcinoma. Both features are diagnostic clues to clear cell adenocarcinoma in the female genital tract. Our case indicates that aspiration cytology is also an effective method of diagnosing a cervical tumor when the tumor is polypoid and the surface is extensively necrotic.- - - - - - - - - - ranking = 6keywords = membrane (Clic here for more details about this article) |
5/44. Exfoliative cytology of lymphoepitheliomalike carcinoma of the uterine cervix. A report of two cases.BACKGROUND: Lymphoepitheliomalike carcinomas (LECs) are morphologically similar to undifferentiated nasopharyngeal carcinoma but occur at sites other than the nasopharynx. They rarely occur in the uterine cervix. Sixty-five cases of LEC of the cervix have been published to date, and the pitfalls of histopathologic interpretation have been discussed. This undifferentiated carcinoma with a prominent lymphocytic infiltrate represents a challenge for the pathologist examining a scant cervical biopsy or Pap smear. Distinguishing LEC as a separate entity is important. Despite the fact that the epithelial component is poorly differentiated, this neoplasm is associated with a lower frequency of lymph node metastases, is potentially radiosensitive and has a better prognosis. Although mentioned in passing in several papers, the exfoliative cytology of this cervical neoplasm has not been adequately discussed. We report the cytologic features of LEC in cervical smears obtained from two patients. CASES: The first patient presented with menometrorrhagia and postcoital bleeding. The cervical smear taken at the time of presentation was reported as unsatisfactory for evaluation. ASCUS was diagnosed on a vaginal smear obtained one year earlier. The second patient presented with a complaint of postcoital bleeding. A cervical smear and the cervical biopsy taken at the time of presentation were reported as ASCUS and high grade dysplasia versus carcinoma, respectively. A retrospective review of the cervical smears revealed rare malignant cells occurring singly or in small groups. The tumor cells had a high nuclear/cytoplasmic ratio, irregular nuclear membrane and hyperchromatic nuclei with coarse chromatin and were obscured by heavy inflammation and blood. The background resembled that of a menstrual smear. CONCLUSION: The diagnosis of LEC of the cervix is often made on a loop electrical excision procedure or on a hysterectomy specimen. The presence of heavy inflammation and blood, which can obscure the malignant nature of the cells, presents the cytopathologist with a challenging diagnosis of LEC in cervical smears. In view of the prognostic implications, it is desirable for the pathologist to classify LEC as a distinct entity.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
6/44. Successful resuscitation of acute massive pulmonary embolism with extracorporeal membrane oxygenation and open embolectomy.Acute massive pulmonary embolism is usually fatal if not treated aggressively, but the management is not standardized. Open pulmonary embolectomy retains a role in the treatment of this disastrous disease. extracorporeal membrane oxygenation has been used for cardiopulmonary support in some patients with life-threatening pulmonary embolism. This article details our experience of a 58-year-old woman suffering from acute cardiopulmonary collapse caused by massive pulmonary embolism. Under extracorporeal membrane oxygenation support, the patient received pulmonary angiography and underwent open embolectomy for a definitive treatment.- - - - - - - - - - ranking = 6keywords = membrane (Clic here for more details about this article) |
7/44. A case report on the treatment of intractable anal pain from metastatic carcinoma of the cervix.INTRODUCTION: Cancer pain in the terminally ill often poses great therapeutic dilemma. Opioids, whilst being useful in most cases, often leaves a patient heavily sedated and constipated at high doses and sometimes, in persistent agony from cancer pain. CLINICAL PICTURE: An Indian lady who suffered from metastatic carcinoma of the cervix experienced tremendous pain and disability despite high doses of narcotics and membrane stabilizers. TREATMENT: A ganglion of impar block and superior hypogastric plexus block were performed with a neurolytic agent. OUTCOME: The patient's pain and opioids usage were markedly reduced. CONCLUSION: Neurolytic nerve block can offer a great therapeutic option in selected cancer patients.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
8/44. A large hamartoma (angioleiomyolipoma) arising from the uterine cervix.A pelvic mass removed from an asymptomatic 52-year-old woman proved to be a large angioleiomyolipoma arising from the cervix and lying within the broad ligament. It was histologically unusual in that it incorporated structures reproducing the sinuses of lymph nodes.- - - - - - - - - - ranking = 4.9869334530839keywords = ligament (Clic here for more details about this article) |
9/44. Transitional cell carcinoma of the uterine cervix. A report of six cases with clinical, histologic and cytologic findings.BACKGROUND: Transitional cell carcinoma of the cervix (TCCC) is a rare neoplasm of recent description. The cytologic characteristics of the tumor have not been published to date. Six cases of TCCC are described, including their clinical, histologic, cytologic and immunohistochemical features. CASES: All cases presented at an advanced clinical stage; two recurred, and one metastasized. Five cases showed a papillary exophytic pattern, and one case showed an "inverted" endophytic pattern similar to that of transitional cell carcinoma of the urothelium (TCCU). The cytokeratin profile was similar to that of squamous cell carcinoma of the cervix (SCCC), positive for CK 7 and negative for CK 20. The cervical smears showed a background that was necrotic or hemorrhagic. The cells with transitional features formed cohesive groups in a multilayered fashion and had an oval or spindle shape with tapered ends. The nuclei were hyperchromatic, with coarse and medium-sized granules that frequently displayed a wrinkled membrane, nuclear grooves and rare pseudoinclusions. The nucleoli were small or absent. Others cells with cytologic characteristics of SCCC were seen in all cases. CONCLUSION: TCCC is a rare neoplasm that probably represents a subgroup of SCCC. The most frequent histologic pattern is papillary-exophytic, but it can be inverted-endophytic. In cervical smears there are cells with characteristics of regular SCCC and others resembling those of TCCU. A larger number of cases is needed to define the evolution and clinical outcome.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
10/44. Epithelioid trophoblastic tumor of the endocervix: a case report.BACKGROUND: It is difficult to recognize epithelioid trophoblastic tumor (ETT) as a trophoblastic disease because of its rarity and growth pattern simulating a carcinoma. CASE REPORT: A 36-year-old woman with stage IB(1) squamous cell carcinoma of the uterine cervix and a high serum beta-human chorionic gonadotropin (beta-hCG) level underwent radical hysterectomy with pelvic and para-aortic lymphadenectomy. However, light microscopic findings and immunohistochemical studies with pan-cytokeratin, epithelial membrane antigen, inhibin-alpha, beta-hCG, and human placental lactogen revealed ETT of the endocervix. The patient is alive with no evidence of disease 12 months after surgery. CONCLUSION: Before the patient is resorted to radical surgical interventions for assumed cervical carcinoma, ETT should be ruled out in women of reproductive age with endocervical tumors and elevated serum beta-hCG levels.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
