Whole-body positron emission tomography with 18F-fluorodeoxyglucose is an effective method to detect extra-pelvic recurrence in uterine sarcomas.

PURPOSE OF INVESTIGATION: To assess the clinical use of F-18-fluorodeoxyglucose positron emission tomography (FDG-PET) in the post-therapy surveillance of uterine sarcoma. METHODS: Eight whole-body FDG-PET studies were performed in seven women with previously treated uterine sarcoma. Conventional image studies (computed tomography) and physical examinations were performed for follow-up. All FDG-PET studies were indicated to localize suspected recurrences noted by conventional methods. RESULTS: The per case sensitivity of the FDG-PET studies and CT scans was 85.7% (6/7) and 100% (7/7), respectively (p = 0.174). FDG-PET was able to detect seven extrapelvic metastastic sites below the diaphragm (7/7, sensitivity: 100%), including the liver, spleen, paraaortic lymph node, spine and paracolic gutter, as well as pulmonary lesions in five patients, while the CT scan detected only three lesions (3/7, sensitivity: 42.9%; p = 0.070). FDG-PET detected only four recurrent pelvic lesions (4/6) and CT scan detected six (6/6) recurrent pelvic lesions (66.7% vs 100%, p = 0.455). CONCLUSIONS: The FDG-PET showed a better detection rate than the abdominal CT scan for extrapelvic metastatic lesions and a similar detection rate as well as abdominal CT scan. FDG-PET can serve as a useful detection tool for patients with uterine sarcomas because nearly 80% of recurrence involve an extrapelvic site.

Presumed Stage IA primary epithelial ovarian carcinoma: the role of complete staging surgery.

PURPOSE: Proper staging is warranted in any patient with primary epithelial ovarian carcinoma (PEOC), but sometimes it cannot always be performed. The prognosis of patients with and without complete staging surgery is to be determined. METHODS: We retrospectively evaluated 61 patients with presumed Stage IA PEOC between January 1970 and December 1993. Inclusion criteria were: being referred patients; no ascites; an intact ovarian tumor without extra-spillage or rupture before, during or after operation; conventional regular exploratory laparotomy without urgency; more than a 5-year follow-up, except for recurrent diseases; a detailed pathology review; and no other systemic disease. Tumors of lower malignant potential (LMP) and cystectomy for removing tumor were excluded. Of the 61 patients, 17 patients received a close observation (Group A), and the others (44 patients) received a re-exploratory laparotomy to complete the staging surgery (Group B). RESULTS: The mean follow-up time was 7.4 years, ranging between 5.4 and 11.1 years, in Group A, and 8.1 years, ranging from 5.6 to 12.7 years, in Group B. Two patients (11.8%) in Group A and seven patients (15.9%) in Group B suffered from recurrence. Two patients finally died of disease, and both were in Group B. CONCLUSIONS: Based on the observation in this study that the recurrence rate of the two groups was not statistically different, close follow-up for patients with presumed Stage IA EOC, but without complete surgical staging surgery, might be acceptable when these patients are treated with postoperative adjuvant chemotherapy.

miRNA-34c-5p inhibits amphiregulin-induced ovarian cancer stemness and drug resistance via downregulation of the AREG-EGFR-ERK pathway.

Epithelial ovarian cancer is the most lethal gynecological cancer mainly due to late diagnosis, easy spreading and rapid development of chemoresistance. Cancer stem cells are considered to be one of the main mechanisms for chemoresistance, as well as metastasis and recurrent disease. To explore the stemness characteristics of ovarian cancer stem cells, we successfully enriched ovarian cancer stem-like cells from an established ovarian cancer cell line (SKOV-I6) and a fresh ovarian tumor-derived cell line (OVS1). These ovarian cancer stem-like cells possess important cancer stemness characteristics including sphere-forming and self-renewing abilities, expressing important ovarian cancer stem cell and epithelial-mesenchymal transition markers, as well as increased drug resistance and potent tumorigenicity. Microarray analysis of OVS1-derived sphere cells revealed increased expression of amphiregulin (AREG) and decreased expression of its conserved regulatory microRNA, miR-34c-5p, when compared with the OVS1 parental cells. Overexpression of AREG and decreased miR-34c-5p expression in SKOV-I6 and OVS1 sphere cells were confirmed by quantitative real-time PCR analysis. Luciferase reporter assay and mutant analysis confirmed that AREG is a direct target of miR-34c-5p. Furthermore, AREG-mediated increase of sphere formation, drug resistance toward docetaxel and carboplatin, as well as tumorigenicity of SKOV-I6 and OVS1 cells could be abrogated by miR-34c-5p. We further demonstrated that miR-34c-5p inhibited ovarian cancer stemness through downregulation of the AREG-EGFR-ERK pathway. Overexpression of AREG was found to be correlated with advanced ovarian cancer stages and poor prognosis. Taken together, our data suggest that AREG promotes ovarian cancer stemness and drug resistance via the AREG-EGFR-ERK pathway and this is inhibited by miR-34c-5p. Targeting AREG, miR-34c-5p could be a potential strategy for anti-cancer-stem cell therapy in ovarian cancer.

Hepatic segmentectomy for curative resection of primary hepatocellular carcinoma.

OBJECTIVES: To evaluate the feasibility and results of segmentectomy for curative resection of hepatocellular carcinoma and to compare the clinicopathological findings of the patients according to the tumor location in the liver. DESIGN: Case series. SETTING: A tertiary care center. PATIENTS: Seventy-five patients with Child's grade A or B liver function who had hepatocellular carcinoma that was confined to one segment and who underwent segmentectomy for curative resection of the tumor. The patients were divided into four groups: group P (posterior segmentectomy, n = 23); group A (anterior segmentectomy, n = 10); group M (medial segmentectomy, n = 16); and group L (lateral segmentectomy, n = 26). MAIN OUTCOME MEASURE: Disease-free survival rate. RESULTS: Seventy-three percent of the patients had cirrhosis of the liver. The surgical mortality and morbidity rates were 5.3% and 36.0%, respectively. The 1-, 3-, and 5-year disease-free survival rates were 61.9%, 39.1%, and 26.3%, respectively, and were not significantly different among the four groups (P = .86). Group L had the least operative blood loss and shortest operative time when compared with the other three groups (P < .05). The postoperative liver function changes were mild and transient in the four groups of patients. With regard to pathological factors, only tumor size differed among the groups (tumors in group L were significantly larger than those in the other three groups, P < .05). Forty-three percent of the recurrent tumors were solitary in the early stage, with 81% involving the segment(s) adjacent to the resected one and 57% being confined solely to the segment adjacent to the resected segment. Patients having recurrent hepatocellular carcinomas had significantly larger tumors at the time of resection than did those without recurrence (P = .03). CONCLUSIONS: Hepatic segmentectomy is an effective therapeutic approach for small hepatocellular carcinomas and can be done safely even in patients with chronic liver disease and impaired liver function.

Clinical, virological, and pathological significance of hepatic bile duct injuries in Chinese patients with chronic hepatitis C.

PURPOSE: Hepatic bile duct injuries are characteristic histological findings in patients with chronic hepatitis C virus (HCV) infection. However, the pathogenesis and clinical significance of this phenomenon remain unclear. The aims of this study were to evaluate the prevalence and clinical significance of hepatic bile duct injuries in Chinese patients with chronic hepatitis C. METHODS: One hundred and seventeen Chinese patients with chronic hepatitis C were enrolled. Clinical, biochemical, immunological (serum autoantibodies and cryoglobulinemia), histological, and virological data (serum HCV RNA titer and HCV genotype) were compared between patients with and without hepatic bile duct injuries. RESULTS: Eighty-three (71%) of the 117 patients with chronic hepatitis C had hepatic bile duct injuries. Patients with hepatic bile duct injuries had a significantly higher frequency of HCV genotype 1b; a higher mean serum globulin level; significantly higher mean scores for histological periportal necro-inflammation, portal inflammation, and fibrosis; and more severe portal lymphoid aggregation/follicles when compared with patients without hepatic bile duct injuries (P < 0.05, all). No significant differences in the presence of serum autoantibodies, cryoglobulinemia, mean serum HCV RNA titer, or response to interferon treatment were noted between the two groups. Multivariate logistic regression analysis showed that HCV genotype 1b infection, portal inflammation, and lymphoid aggregation/follicles were significant independent predictors associated with hepatic bile duct injuries. CONCLUSIONS: The presence of hepatic bile duct injuries in Chinese patients with chronic hepatitis C was significantly correlated with HCV genotype 1b infection, and the patients with these injuries had more severe portal inflammation and formation of lymphoid aggregates/follicles.

DNA flow cytometric analysis of primary breast cancer in Chinese women: the relationship of DNA aneuploidy to clinical characteristics.

One-hundred-and-forty fresh frozen breast tissue samples from Chinese patients collected from May 1991 to October 1992 were evaluated for DNA content by flow cytometric analysis. None of the 12 benign tumors displayed aneuploidy. One-hundred-and-twenty-eight of the 140 specimens were histologically proven to be malignant. Ploidy was compared to the clinical characteristics which included age, tumor size, lymph node involvement, menopausal status, steroid receptor status, histological grading and pathological staging. After univariate and multivariate analyses, aneuploidy was more frequently identified in progesterone receptor negative and high grade tumors. This study suggests that an aneuploid DNA content in a breast cancer specimen may indicate more aggressive cancer.

Factors predictive of liver cirrhosis in patients with chronic hepatitis B: a multivariate analysis in a longitudinal study.

OBJECTIVE AND DESIGN: Chronic hepatitis B virus (HBV) infection may lead to liver cirrhosis; however, factors associated with the development of cirrhosis have been incompletely studied. A total of 516 patients with chronic hepatitis B were followed up longitudinally to determine their outcome. METHODS: The clinical and pathological features were compared between those with and without cirrhosis occurrence. The risk factors were analysed, and the probability of the development of cirrhosis was estimated. RESULTS: During a mean follow-up period of 5.7 +/- 3.4 years (range 1-17 years), cirrhosis occurred in 71 patients, with a calculated annual incidence of 2.4%. Older age (> 45 years) at entry, male gender, persistent hepatitis (> 1.5-fold rise of serum alanine aminotransferase levels for at least one year) and diabetes mellitus were identified as independent risk factors of cirrhosis in a multivariate analysis (odds ratios 8.0, 19.3, 2.0 and 5.2, respectively; P values all < 0.05). A logistic regression equation was used to predict the probability of cirrhosis occurrence, which was as high as 76.6% when all risk factors were present. Acute exacerbation or super-infection by hepatitis C or D viruses were not significant predictors. Patients with subsequent cirrhosis had higher initial hepatic histological necro-inflammatory activities when compared to age- and sex-matched non-cirrhotic controls (Knodell's scores: 8.2 +/- 2.4 versus 6.0 +/- 4.1, P< 0.05). CONCLUSIONS: Patients who were elderly, male, diabetic or had a history of persistent and histologically severe hepatitis were at increased risks of liver cirrhosis. Aggressive anti-viral therapy may be needed for these patients and they should be closely monitored for HBV-related late complications.

Clinical, virological, immunological, and pathological significance of GB virus C/hepatitis G infection in patients with chronic hepatitis C.

GB virus-C (GBV-C)/hepatitis G virus (HGV), a single-strand RNA virus, has been identified as a transfusion transmissible virus and categorized as a member of the Flaviridiae family. GBV-C/HGV superinfection in patients with chronic hepatitis C is not seen uncommonly, most likely because of the similar transmission routes. This study aimed to investigate the prevalence of GBV-C/HGV infection in 100 Chinese patients with histologically proven chronic hepatitis C, and to clarify the clinical, virological, immunological, and histopathological impact of GBV-C/HGV infection on chronic hepatitis C patients. Serum GBV-C/HGV RNA was positive in 22 (22%) of the 100 chronic hepatitis C patients. There were no significant differences in mean age, gender, and serum liver biochemical tests between GBV-C/HGV infected and non-infected chronic hepatitis C patients. The HCV genotype distribution and mean serum HCV RNA level were not significantly different between patients with and without GBV-C/HGV co-infection. The presence of serum autoantibodies (anti-nuclear antibody and anti-smooth muscle antibody) and cryoglobulinemia showed no significant difference between the two groups. Liver histopathological analysis revealed no significant difference in the grade of periportal, portal, and intralobular necro-inflammation, in the stage of fibrosis/cirrhosis, or in the presence of steatosis and lymphoid aggregation/follicle formation between patients with and without GBV-C/HGV infection. However, a higher degree of bile duct damage was noted in chronic hepatitis C patients co-infected with GBV-C/HGV infection than in those without infection (P=0.036). In conclusion, GBV-C/HGV infection had no apparent influence on the clinical, immunological, or virologic features of patients with chronic hepatitis C. However, the clinical significance of a higher degree of bile duct damage in patients with HCV and GBV-C/HGV co-infection deserves further investigation.

Breast mass due to alveolar soft part sarcoma of the pectoris major muscle.

We present a case of alveolar soft part sarcoma (ASPS) of the pectoris major muscle in a 20-year-old female. She felt a mass in her right side breast for 7 years. The lesion was almost the same size with occasional throbbing pain and tenderness. Fine needle aspiration of the tumor was performed in the OPD and suspicious abnormal cells were reported. Ultrasound (US) examination of the breast revealed a large heterogeneously hypoechoic lesion contiguous to the pectoris major muscle. Profound color flow signals were evident in both central and peripheral regions of the mass. Spectral Doppler US showed high flow velocity in the tumor vessels with resistivity index of 0.73. Surgical intervention was performed and the histological examination yielded a diagnosis of ASPS.

Steroid cell tumors of the ovary: clinical, ultrasonic, and MRI diagnosis--a case report.

Steroid cell tumors of the ovary are rare sex-cord neoplasms which account for less than 0.1% of all ovarian tumors. They have been divided into two subtypes according to their cell of origin as follows: stromal luteoma, and Leydig cell tumors, and a third subtype with lineage unknown is a steroid cell tumor, not otherwise specified (NOS). The clinical presentation may take many forms, including pain, abdominal distention and bloating, but perhaps the most interesting and noticeable presentations are those related to the hormonal activity and virilizing properties of the tumor. No radiological features of the steroid cell tumor, NOS have been presented in the literature. This report presents the MRI and ultrasonographic findings of a patient having steroid cell tumor, NOS, of the right ovary with metastasis to the uterus.

Spontaneous expulsion of a uterine submucosal leiomyoma after administration of a gonadotropin-releasing hormone agonist.

A 40-year-old primigravida presented with acute urine retention. Ultrasound examination revealed a large uterine submucosal leiomyoma and GnRH-a was administered. The leiomyoma grew to over twice its original size and protruded through the introitus. After 10 days, it was expelled completely and removed by resectohysteroscopy. The expulsion of the leiomyoma was most likely a result of GnRH-a's flare-up effect.

Rapid progression of squamous cell carcinoma of the cervix after hyperbaric oxygenation.

The role of hyperbaric oxygenation in the treatment of radiation-induced sequelae and chronic ulcer is well established. On the contrary, a possible cancer-causing or growth-enhancing effect by hyperbaric oxygenation was highly controversial. Herein, we present a 55-year-old Chinese woman with recurrent squamous cell carcinoma of the cervix on her left inguinal area. She received concurrent chemoradiation therapy followed by radical inguinal lymphadenectomy due to persistent tumor mass. The patient was complicated with severe radiation fibrosis and unhealed wounds, so she was treated with hyperbaric oxygenation (HBO). However, the patient died of complications of the disease after completing HBO therapy I month later and autopsy of the patient showed carcinomatosis of the abdominal cavity and lower abdominal wall. Because previous studies have been inconclusive regarding the effect of HBO on tumor cells, we reviewed the possible relation between the HBO and tumor cells.

Ovarian metastasis from cervical carcinoma.

OBJECTIVE: To study the prognosis and metastatic route of cervical carcinoma with ovarian metastasis. METHOD: From 1980 to 1993, 10 of the 1507 patients with cervical carcinoma operated and who had ovarian metastasis were analyzed. RESULTS: Six patients had squamous cell carcinomas and 4 patients had adenocarcinomas. Their mean age was 45 years. Six of 9 patients undergoing pelvic lymphadenectomy had nodal metastasis. One patient did not have nodal dissection in the treatment course. Five of 10 patients had involvement of corpus: 3 were accompanied with nodal metastasis, 1 was not and 1 other was unknown. None of our cases survived more than 5 years. Their mean survival time was 20.8 months for squamous cell carcinomas and 29 months for adenocarcinomas. CONCLUSIONS: (1) Ovarian metastasis is histologically one of the ominous signs of cervical carcinomas regardless of stage. The prognosis of patients with ovarian metastasis from cervical squamous cell carcinoma from our data is not different from those from cervical adenocarcinoma. (2) Lymphatic spread and transtubal implantation are possible pathways of cervical cancer metastasizing to ovary, and involvement of the corpus may potentiate this mechanism.

Prognosis-predicting system based on factors related to survival of cervical carcinoma.

OBJECTIVE: To establish a different category system based on grouping of the risk factors in patients with cervical smear. METHODS: Univariate and multivariate analyses of factors associated with survival time were performed in 443 patients with stage Ib-IIa squamous cell carcinoma (SCC) from 1985 to 1989. RESULTS: Univariate analysis showed that parametrial extension, bulky tumor size (> or = 4 cm), uterine body involvement, poor differentiation and pelvic lymph node (LN) metastasis were prognostically significant. However, by multiple regression method, only LN metastasis, deep stromal invasion (DSI), and poor differentiation (PD) were significantly related to the patient's survival time with risk ratios of 2.78, 2.61 and 1.52, respectively. A prognosis-predicting system was established on the basis of these simplified factors: groups of high, intermediate, low and very low-risks, obtained survival rates of 93-96%, 77%, 51% and 25-37%, respectively. CONCLUSIONS: Using this simple model, cervical carcinomas can be classified prognostically for predicting 5-year-survival rates, and for risk-guided therapy in the future.

Intraperitoneal cisplatin-based chemotherapy vs. intravenous cisplatin-based chemotherapy for stage III optimally cytoreduced epithelial ovarian cancer.

OBJECTIVE: To compare the survival between intraperitoneal cisplatin-based chemotherapy (IPCT) and intravenous cisplatin-based chemotherapy (IVCT) in stage III epithelial ovarian cancer with minimal residual disease (<1 cm) after primary debulking surgery. METHOD: One hundred and thirty-two patients with stage III epithelial ovarian cancer after optimal primary debulking surgery with minimal residual disease between April 1990 and March 1995 were entered into a randomized clinical trial in which IPCT or IVCT was administered at 3-week intervals. Patients in the IPCT arm received cisplatin-based (100 mg/m(2)) intraperitoneal chemotherapy. Patients in the IVCT arm received cisplatin-based (50 mg/m(2)) intravenous chemotherapy. The tumor response was assessed every 3 months. The hematological toxicity using the South West Oncology Group (SWOG) toxicity criteria was assessed. Catheter complications associated with intraperitoneal chemotherapy were also analyzed. RESULT: The estimated median survival in the IPCT group was 43 months (95% confidence interval, 34-54) and IVCT group was 48 months (95% confidence interval, 37-59). The hazard ratio of death was not statistically significant between IPCT and IVCT (hazard ratio, 1.13; 95% CI, 0.69-1.86; P=0.317). The frequencies of hematological toxic effects were significantly lower in the IPCT group than in the IVCT group. CONCLUSION: Intravenous and intraperitoneal chemotherapy are associated with equivalent survival in patients with minimal residual stage III epithelial ovarian cancer after optimal cytoreductive surgery.

Contribution of immunocytochemistry in routine diagnostic cytology.

The authors report the experience of applying immunocytochemistry in routine cytological examination and its contribution for diagnosis during a period of 3 yr in Veterans General Hospital-Taipei, Taiwan. From August 1991 to July 1994, the cytology laboratory received 5,762 non-gynecologic specimens with urine excluded. Immunocytochemistry was performed selectively in problematic cases. A total of 215 stainings including 124 epithelial markers, 50 lymphoma/leukemia markers, 22 neuroglial and choroid plexus markers, seven mesenchymal markers, six melanoma markers, and six others was performed on 145 specimens consisting of 89 effusions, 28 fine-needle aspirations, 11 cerebrospinal fluids, and 17 other specimens. Effusions were by far the most frequent specimens for immunocytochemistry and the epithelial markers were the most frequently used antibodies. The immunocytochemical results were essential in 41 specimens (28%), confirmatory in 37 (26%), and non-contributory in 67 (46%). Essential and confirmatory results occurred in 49% of effusions (44/89), 71% of fine-needle aspirations (20/28), 55% of cerebrospinal fluids (6/11), and 47% of other specimens (8/17). It is concluded that immunocytochemistry is proved to be a good aid for the final diagnosis of daily cytologic practices in which the fine-needle aspiration specimens are benefitted best.

Adult embryonal rhabdomyosarcoma metastatic to the breast and diagnosed by fine needle aspiration. A case report.

BACKGROUND: Metastasis to the breast from extra-mammary malignancies is rare, but its recognition is important. A solitary metastasis must be distinguished from the primary breast cancer because the treatment and prognosis are quite different. CASE: A 30-year-old female presented with a 4.0-cm, solitary, nontender mass in the upper outer quadrant of the right breast 11 months after primary surgery for maxillary sinus embryonal rhabdomyosarcoma. The cytomorphology revealed features of small round cell tumor. Immunocytochemical staining disclosed a positive reaction to vimentin and desmin and negative reaction to cytokeratin, confirming the diagnosis of rhabdomyosarcoma. CONCLUSION: Fine needle aspiration with ancillary studies is essential in the diagnosis of metastatic malignancy of the breast in order to avoid unnecessary mastectomy and to implement appropriate systemic therapy.

Establishment and characterization of a cell line, MT-213-VGH, isolated from a mixed müllerian tumor of the uterus.

OBJECTIVE: To establish a cell line from a woman with malignant mixed müllerian tumor of the uterus and to examine the biologic properties of this cell line (MT-213-VGH). STUDY DESIGN: Cells were cloned by the limiting dilution method. Histologic staining of mixed müllerian (mesodermal) tumor (MMMT) cells was performed with May-Grünwald-Giemsa and hematoxylin and eosin stain. After more than 20 passages, cells were used to estimate the population-doubling time and colony-forming efficiency of MMMT cells. The cell line exhibited considerable variation in the degree of sensitivity to diverse chemotherapy drugs in vitro. RESULTS: MMMT cells containing antigens for vimentin and myoglobin were detected, but those for CA-125, carcinoembryonic antigen, cytoskeleton, desmin, epithelial membrane antigen and fibronectin were not found. In addition, MT-213-VGH cells contained a mucinous substance; its chromosome model number is 45. This cell line showed differential sensitivities to chemotherapeutic agents, such as bleomycin, cisplatin, 5-fluorouracil and vinblastine. CONCLUSION: The establishment and availability of the number cell line MT-213-VGH for a malignant mixed müllerian tumor of the uterus should assist in research on new methods of managing this type of gynecologic cancer.

Small cell carcinoma of the cervix: analysis of clinical and pathological findings.

PURPOSE OF INVESTIGATION: An attempt to better identify small cell carcinoma of the cervix and evaluate its prognosis. METHODS: From January of 1970 to March of 1995, a total of seven patients diagnosed with small cell carcinoma of the cervix by pathologic revision were retrospectively reviewed. Clinical information including age, clinical stage, lymph-vascular space invasion, lymph node metastases, prognoses were analyzed. RESULTS: All specimens stained positive for neuron-specific enolase (NSE) and four were positive for chromogranin (CGR). The majority of patients (71%) died of disease within 18 months. Only one patient had an abnormal Pap smear before definite diagnosis, and only one patient was well and alive after a combination of surgery and multi-agent chemotherapy (p<0.05). CONCLUSION: Pap smears may not be an appropriate screening method for detecting small cell carcinoma of the cervix. Immunohistological staining may be helpful in diagnosis of small cell carcinoma of the cervix. Because of a very poor prognosis, more effective therapeutic protocol should be further defined in the management of cervical small cell carcinoma.

Extramammary Paget's disease found by abnormal vulvar brush sampling.

INTRODUCTION: Doctors are usually reluctant to perform a vulvar biopsy on a patient with non-specific chronic vulvitis--especially because of the rarity of vulvar malignancy in young women--until the lesion is suspected of being malignant. Therefore, most cases of extramammary Paget's disease (EMPD) were originally misdiagnosed as chronic and recurrent vulvar lesions. Late diagnosis of invasive lesions occurring in elderly females have resulted in cases of death. CASE: A 37-year-old patient showed an extended lesion on the vulva and perineum. In addition, abnormal cells were found from a vulvar scrape smear, and a following punch biopsy was used to diagnose and determine the extension of the disease. CONCLUSION: Diagnosis and demarcation of EMPD remain difficult due to the multifocal lesions and subtle nature of the disease. Brush sampling taken from suspicious areas can be a guide for multiple biopsies to demarcate the lesion before major surgery. A brush biopsy is presented as a first-step method to detect vulvar malignancy.
