Abstract
The diagnosis of benign, uncertain malignant potential, and malignant uterine smooth muscle tumors depends on mitotic counts, nuclear atypia, and other morphologic features. This study was undertaken to evaluate the utility of selected immunohistochemical markers in differentiating these tumors. Fifteen cases of cellular leiomyoma, 7 cases of smooth muscle tumor of uncertain malignant potential (STUMP), and 12 cases of leiomyosarcoma were immunostained for MIB-1 (Ki-67), p53, estrogen receptor and progesterone receptor (PR) using monoclonal antibodies and the avidin-biotin-peroxidase method. The percentage of cells stained was subjectively assessed to the nearest 5%. One percent was used for rare positive cells. MIB-1 expression of > or =15% was seen in 11 and expression of p53 in > or =15% cells was present in 5 of 12 leiomyosarcomas. MIB-1 and/or p53 expression of >15% was seen in all 12 leiomyosarcomas but in none of the 7 STUMP or 15 cellular leiomyomas. PR was absent in 10 of 12 leiomyosarcomas but present in 7 of 7 STUMP and 14 of 15 cellular leiomyomas. MIB-1 of 5% to 10% was seen in 6 of 7 STUMP but in only 1 of 15 cellular leiomyomas. MIB-1, p53, and PR are useful in differentiating leiomyosarcoma from STUMP and cellular leiomyoma. MIB-1 is useful in distinguishing STUMP from cellular leiomyomas.

Abstract
OBJECTIVE To evaluate a new technique for processing endometrial cytology for the diagnosis and exclusion of endometrial cancer. STUDY DESIGN All women at risk for endometrial cancer with clinical indications for endometrial biopsy were evaluated by endometrial brush biopsy (Tao Brush, Cook OB-GYN, Bloomington, Indiana) and Pipelle (Cooper Surgical, Shelton, Connecticut) endometrial biopsies during one office visit. Patients were followed longitudinally for the development of endometrial cancer or until undergoing dilatation and curettage or hysterectomy. All comparisons were analyzed using the chi 2 or t test. RESULTS One hundred one women (mean age, 58; range, 35-86) had endometrial biopsies performed. Median follow-up was > 21 months (range, 3-29). Twenty-two had cancer or atypia, while the remaining had benign diagnoses. When correlated with the final diagnosis, the Tao Brush had 95.5% sensitivity and the Pipelle, 86% sensitivity. Both devices had 100% specificity, positive predictive value of 100% and negative predictive value of 98%. When the results of the two biopsy devices are considered together, the positive and negative predictive value for detecting or excluding endometrial cancer was 100%. Based on 1998 Medicare reimbursements, a simultaneous second office biopsy using the Tao brush could save approximately $67 per case as compared to a sonohistogram and much more when compared to dilatation and curettage. CONCLUSION Endometrial cancer can be reliably detected and excluded using these two distinct office biopsy devices simultaneously during one office visit. In patients with an indication for endometrial biopsy, no further diagnostic test may be necessary to exclude or diagnose endometrial cancer or atypia.

Abstract
A case of myxoid leiomyosarcoma of the uterus arising in a leiomyoma is reported. Although the tumor showed very low mitotic activity ranging from zero to 2/10 HPF, the presence of infiltrative pattern of growth and a high MIB-1 index (60% of cells positive) established the diagnosis. Myxoid leiomyosarcoma may arise in leiomyoma.

Abstract
The BK virus (BKV) belongs to the family of the polyoma group, which contains three species: JC, which is responsible for progressive multifocal leukoencephalopathy in acquired immunodeficiency syndrome (AIDS); simian virus 40 (SV40), which is a simian virus of little pathologic significance in humans; and BKV, which is usually not pathogenic and is found in the urine of asymptomatic individuals. Recently BKV has been reported to cause symptomatic infection in renal transplant patients. The authors report a rare case of a 14-year-old boy with AIDS who developed a BKV infection of the lung and kidney that progressed to diffuse alveolar damage and death. The infected type II pneumocytes in the lung and the tubular epithelial cells in the kidney showed large, homogenous purple intranuclear inclusions. The absence of necrosis and destruction made it possible to distinguish BKV infection from herpes simplex. The size of the infected cells and the lack of a halo around the nuclear inclusion helped rule out cytomegalovirus as the cause of infection. Electron microscopy detected the presence of 40-nm intranuclear viral particles compatible with BKV, and in situ hybridization established the diagnosis.

Abstract
Various cervical lesions at times may be difficult to distinguish from one another on routine hematoxylin and eosin stains, and immunostaining for the proliferation-associated antigen Ki-67, using monoclonal antibody MIB-1, can aid their distinction. The reduced MIB-1 expression in atrophy and increased MIB-1 expression in dysplasia permits easy distinction between these conditions. Presence of MIB-1 in more than 15% of basal cells and/or in surface half of the epithelium favor a diagnosis of condyloma over squamous metaplasia or inflammatory changes. Normal endocervix shows MIB-1 positivity in less than 10% of the cells, but usually in more than 20% of cells in cervical adenocarcinoma. With increasing grade of dysplasia, the percentage of MIB-1 positive cells is increased, and positive cells are seen in the higher levels of the epithelium. Presence of more than 20% MIB-1 positive cells in Pap smears showing atypical cells of uncertain significance is associated with a diagnosis of dysplasia on subsequent biopsies. Cauterized tissues with dysplasia show MIB-1 expression similar to adjacent noncauterized dysplastic areas. MIB-1 expression is, therefore, useful in evaluating various cervical lesions.

Abstract
Interpretation of cervical cone biopsy margins removed by loop electrosurgical excision procedure is often problematic as a result of cautery artifacts. In this study, MIB-1 expression in cauterized tissues was almost identical to that in the adjacent noncauterized epithelium (correlation coefficients 0.97-0.98). Cauterized dysplastic/condylomatous epithelium showed significantly greater expression of MIB-1 than cauterized normal epithelium (p < or = 0.004) at all levels of the epithelium. Cut-off points for distinguishing dysplastic/condylomatous epithelium from normal epithelium were >15%, 30%, 5%, and 1% of cells in the basal, basal one-third, middle one-third, and surface one-third of epithelium, respectively.

Abstract
Twenty-four predominantly papillary carcinomas of the endometrium, 10 serous and 14 endometrioid, were compared using a variety of immunohistochemical antibodies, including p53, estrogen and progesterone receptors, carcinoembryonic antigen, and E-cadherin. These were selected to attempt to find clues to explain the disparate behavior of these two tumor subtypes. We found that 6 of 8 (75%) serous carcinomas had a p53 reactivity score of 300, whereas 90% of endometrioid tumors had a p53 reactivity score of less than 20 (p = 0.0008). Combined estrogen and progesterone hormone reactivity was positive in 13 (100%) of endometrioid lesions compared with 4 of 8 (50%) of serous lesions (p = 0.0117). The significantly greater p53 expression and its significantly diminished hormone receptor expression indicate that papillary serous carcinomas belong to the type II group of endometrial carcinomas that occur in a background of atrophic endometrium, are high grade, present with high stage disease, and have a poor prognosis. In contrast, papillary endometrioid carcinomas, which belong to type I carcinomas, often arise in a background of estrogen-stimulated endometrial hyperplasia, are usually well-differentiated, and have a good prognosis. Early p53 mutations in papillary serous carcinoma as well as in endometrial intraepithelial serous carcinoma may partially explain their proclivity for early intra-abdominal dissemination. Carcinoembryonic antigen expression was similar in both groups and therefore is not useful to characterize possible differences in the cell of origin. The reactivity scores for E-cadherin were also similar in the two tumor subtypes, thus not supporting the hypothesis that decreased cell to cell adhesion molecules might contribute to early dissemination of serous lesions.

Abstract
Both atrophic and dysplastic cervical squamous epithelia show lack of maturation, nuclear crowding, and increased nuclear/cytoplasmic ratio. Because of these similarities, distinguishing dysplasia from atrophy in cervical biopsies from elderly patients is often problematic. Because dysplasia shows increased proliferation and atrophy has decreased proliferation, the possible utility of MIB-1 in distinguishing dysplasia from atrophy was evaluated. One or more of the following criteria were present in all nine cases with dysplasia and in none of the 17 cases with atrophy: MIB-1 expression in > 20% of cells in the basal one-third of the epithelium, > 5% of cells in the middle one-third of the epithelium, and > 1% of cells in the upper one-third of the epithelium. MIB-1 immunostaining is useful in distinguishing dysplasia from atrophy.

Abstract
BACKGROUND Leuprolide acetate has been used to decrease uterine size and shrink leiomyomata. In carefully selected patients, its treatment benefits are well recognized. However, if leuprolide acetate is inadvertently given to a patient with an unsuspected leiomyosarcoma, complications may occur. CASE A patient presumed to have leiomyomata was treated with monthly injections of leuprolide acetate. In the third month of treatment, unusual manifestations, including increased bleeding, aborting mass, urinary retention, and severe pain, occurred suggesting a possible malignancy and requiring immediate operation. CONCLUSION The use of leuprolide acetate can delay the diagnosis and treatment of leiomyosarcoma and thus may increase the risk of morbidity and affect the treatment outcome of patients with leiomyosarcoma. The histologic changes ascribed to leuprolide acetate treatment in leiomyomata also were seen in this leiomyosarcoma.

Abstract
Changes of condyloma are sometimes difficult to distinguish from changes seen with inflammation or with squamous metaplasia (SM) in the uterine cervix. Cervical condylomas show increased proliferative activity, so we sought to discover whether this increased activity is more than that seen in SM or with inflammation. Mitotic activity per 10 high power fields was measured in 22 cases with SM, 22 cases with exocervix only, 26 cases with inflammation, and 34 cases with condylomas. The percentage of basal cells staining for MIB-1 was compared between 27 cases with condyloma, 11 cases each with SM and inflammation, and 13 cases with exocervix. Mitotic activity was significantly increased in cervical condylomas (7.6 +/- 6.6, mean +/- standard deviation) compared with SM (1.4 +/- 1.4, P < .0001), inflamed epithelium (1.6 +/- 1.4, P < .0001), and exocervix (1.4 +/- 1.5, P < .0001). More than 15% of basal cells stained for MIB-1 in 18 of the 27 condylomas, 1 of 11 cases with SM, 1 of 11 cases with inflammation, and none of the 13 cases with exocervix (P = .003, .003, and .0006 respectively). Expression of MIB-1 in the surface half of the epithelium was seen in 18 (66%) of the 27 cases with condyloma but in none of the 24 controls (P < .00001). MIB-1 in the surface half of the epithelium and/or in more than 15% of the basal cells was seen in 24 (90%) of the 27 condyloma cases and 1 (4%) of the 24 control cases (P < .00001). A finding of 6 or more mitoses per 10 high power fields, expression of MIB-1 in the surface half of the epithelium, and more than 15% of basal cells staining for MIB-1 should support a diagnosis of condyloma over metaplastic or inflammatory changes.

Abstract
Cervical condylomas associated with HPV types 6/11 rarely progress to dysplasia; this progression is more commonly seen in cervical condylomas with HPV types 16/18/31/33/35. This investigation was undertaken to determine if more frequent atypical mitotic figures (MFs) and higher proliferative activity are seen in high-risk condylomas. HPV types present in cervical condylomas were determined by in situ hybridization with biotinylated probes. The cases were also stained immunohistochemically for MIB1. The percentage staining of basal, parabasal, and suprabasal cells was determined by counting 100 cells in the most intensely stained areas. MFs and atypical MFs were counted per 10 high-power-fields (HPFs). Condylomas with HPV 6/11 showed higher MIB1 expression in the basal layer than condylomas with HPV 16/18 and 31/33/35 (p = 0.013). Atypical MFs were seen more frequently in condylomas with HPV types 16/18/31/33/35 (p = 0.02). Differences in mitotic activity and in MIB1 expression in parabasal and suprabasal layers did not reach statistical significance. The presence of atypical MFs may make a greater contribution than increased proliferative activity to progression to dysplasia in cervical condylomas.

Abstract
OBJECTIVE To evaluate steroid hormone receptor status in the uterosacral ligament, a structure that contributes to pelvic support. METHODS A descriptive study was conducted by sampling the uterosacral ligaments from 25 consecutive women undergoing hysterectomy by the primary author for nonmalignant conditions. Using immunohistochemical staining techniques, uterosacral ligaments were assessed for the presence and location of estrogen and progesterone receptors. Positive and negative controls were used. Confirmation of the uterosacral ligament was performed histologically. RESULTS Using commercially available monoclonal antibodies, estrogen and progesterone receptors were detected in the nuclei of smooth muscle cells of the uterosacral ligament in all patients, regardless of variations in age, race, menopausal status, parity, body mass index, and medications affecting serum steroid hormone levels. Hormone receptors were not found in the collagen, vascular, or neuronal components. CONCLUSION The presence of estrogen and progesterone receptors in the uterosacral ligaments means that this structure may be a target for estrogen and progesterone. This finding might suggest a possible role for steroid hormones in pelvic support.

Abstract
OBJECTIVE Our purpose was to evaluate whether tamoxifen has estrogenic endometrial effects as defined by histologic study or alterations in steroid hormone receptor expression. STUDY DESIGN Nineteen postmenopausal tamoxifen-treated breast cancer patients who also had endometrial sampling were identified from files in the Department of Obstetrics and Gynecology. To examine the subgroup of 15 polyps, age-matched, non-hormonally treated patients with polyps (n = 8) or atrophic endometria (n = 5) served as comparison groups. Proliferative (n = 3) and secretory (n = 5) endometria served as procedural controls. Immunohistochemical studies for steroid receptors (estrogen, progesterone) were performed. RESULTS Glandular cell progesterone receptor was significantly increased and stromal cell estrogen receptor was significantly decreased in tamoxifen-treated versus atrophic endometria. Progesterone receptor staining was not significantly different in tamoxifen-treated versus control polyps, although staining was high in both groups. Stromal cell estrogen receptor staining was significantly reduced in tamoxifen-treated versus control polyps, although there were no histologic differences. Reduced stromal cell estrogen receptor and increased glandular cell progesterone receptor staining was found in all tamoxifen-treated endometria regardless of the diagnosis. CONCLUSION The tamoxifen-associated changes in endometrial steroid receptors support an estrogenic effect that is independent of histologic diagnosis and duration of use. This may contribute to the pathogenesis of tamoxifen-associated polyps and carcinomas.

Abstract
Endometrial polyps are a frequent cause of abnormal uterine bleeding, but their pathogenesis is poorly understood. This study was undertaken to investigate if endometrial polyps result from localized overexpression of estrogen receptors (ERs) or reduced expression of progesterone receptors (PRs). Fourteen cases of endometrial polyps, in which normal cycling endometrium was also present on the same slide, were immunostained for ERs and PRs. Percentages of positive cells in glands and stroma for each receptor were subjectively assessed to the nearest 5%. The intensity of staining was recorded on a scale from 1+ to 4+. The level and intensity of staining in polyps were compared with the staining in normal endometrium. Fewer stromal cells in polyps expressed ERs and PRs compared with cycling endometrium (% ER = 55.9 +/- 25.8 vs. 74.3 +/- 25.8, p = 0.03; % PR = 56.1 +/- 28.2 vs. 87.5 +/- 10.1, p = 0.002). Stroma in polyps also had significantly reduced intensity of staining for PRs, but not for ERs (intensity PR = 2.7 +/- 1.4 vs. 3.5 +/- 0.7, p = 0.015; intensity ER = 2.1 +/- 0.7 vs. 2.4 +/- 0.8, p = 0.45). There were no significant differences in expression of ERs and PRs in the endometrial glands in endometrial polyps compared with normal endometrium (% ER = 75.4 +/- 32.5 vs. 70.7 +/- 39.2. p = 0.25; % PR = 79.6 +/- 32.8 vs. 80.4 +/- 34.4, p = 0.8; intensity ER = 2.7 +/- 0.9 vs. 2.4 +/- 1, p = 0.15; intensity PR = 2.9 +/- 1.4 vs. 3.4 +/- 0.7, p = 0.15). We conclude that endometrial polyps may result from a decrease in ER and PR expression in stromal cells. Because of these receptor-negative stromal cells, endometrial polyps may be relatively insensitive to cyclic hormonal changes.

Abstract
This study compares morphometric features of endometrial papillary carcinomas, serous and endometrioid types, in an effort identify characteristics that predict clinical outcome. Fifty-one consecutive patients with papillary carcinoma were identified at NYU Medical Center from January 1979 through December 1991 and were followed through 1994. Morphologic analysis was conducted by investigators (R.D. and K.M.) blinded as to original diagnosis, depth of invasion, stage and outcome. Of 25 variables analyzed, six were significantly associated with reduced survival, namely marked nuclear pleomorphism, multinucleated cells, hobnail cells, psammoma bodies, uneven papillary borders, and inflammation. Serous carcinomas showed a highly significant (p = 0.0001) association with reduced length of recurrence-free survival, with a median survival of 27 months (mean +/- SE, 38.9 +/- 7.0) versus 95 months (106.7 +/- 15.3) for patients with endometrioid types. Of six morphologic characteristics that correlated with reduced recurrence-free survival by univariate analyses, only one, nuclear pleomorphism, showed a significant association with an adverse outcome in a multivariate regression analysis (p = 0.0020), even after adjustment for the effect of tumor stage. Therefore, we believe that the presence of marked nuclear pleomorphism should serve as the major criterion for making a diagnosis of serous carcinoma. In tumors with moderate nuclear pleomorphism, a diagnosis of serous carcinoma is aided by the presence of multinucleated cells, uneven papillary borders, high nuclear/cytoplasmic ratio, apical location of the nucleus, and hobnail cells. These features were significantly associated with a diagnosis of serous carcinoma in our patients.
