RESUMO

OBJECTIVE: The nature and clinicopathologic associations of Löwenstein-Buschke disease are unclear. MATERIALS AND METHODS: 78 anal condylomatous lesions (≥2 cm) were analyzed. Cases were classified based on size as "medium-large"(2-5 cm, n=59), "large" (5-10 cm, n=13) and "giant" ( > 10 cm, n=6). RESULTS: Patients were predominantly males (male/female=70/8). The mean age was 38 years (range:20-66). Two distinct lining types were recognized: 1) Epidermal type, typically lacking overt koilocytotic change, with associated invasive carcinoma in 8%; 2) Mucosal type, often manifesting koilocytotic change, with associated invasive carcinoma in 21%. Three types of high-grade dysplasia were discerned: 1) Basaloid, 8/9 showing high-grade dysplasia/carcinoma in-situ but non-invasive lesions; 2) Keratinizing, innocuous-appearing, but 5/6 was associated with invasion; 3) Giant cell, showing scattered individual bizarre cells, with 3/5 showing invasive carcinoma. Overall, invasion was found in 14% of the cases. The bulbous, broad-based destructive pattern characterizing verrucous carcinomas of the upper aerodigestive tract was not observed. A statistically significant trend existed between the incidence of invasion and size: 8.5% for medium-large, 23% for large, and 50% for giant (p=0.02). There was no discernable trend in the depth of invasion relative to condyloma size. CONCLUSIONS: Our findings suggest that Löwenstein-Buschke lesions are mega versions of conventional condyloma. Being verrucoid, large and minimally invasive, they can be conceptually regarded as a form of verrucous carcinoma, but they do not display the histologic characteristics of verrucous carcinoma defined in the aerodigestive tract. They exhibit two types of linings: the mucosal type that often shows koilocytotic changes, and the epidermal type that can be difficult to recognize in biopsies. These lesions may be associated with invasive carcinoma, albeit limited in amount.

RESUMO

BACKGROUND: Recommendations for high-risk human papillomavirus (HR-HPV) testing as an adjunct to cytology for cervical cancer screening differ by age group, because HR-HPV tests lack adequate specificity in women aged <30. Here, we assess age-group differences in HPV types and other risk factors for cervical intraepithelial neoplasia (CIN) grade 3 or worse (CIN3+) versus CIN0-2 in women from four colposcopy clinics. METHODS: Women ages 18 to 69 (n = 1,658) were enrolled and completed structured interviews to elicit data on behavioral risk factors prior to their examinations. HPV genotyping was done on exfoliated cervical cell samples. We estimated relative risks (RR) for HPV types and cofactors for CIN3+, overall and stratified by age group. RESULTS: After 2 years of follow-up, we identified 178 CIN3+, 1,305 CIN0-2, and 175 indeterminate outcomes. Nonvaccine HR-HPV types were only associated with CIN3+ among women ≥ 30 (RR = 2.3, 95% CI: 1.5-3.4; <30: RR = 0.9). Among all HR-HPV-positive women, adjusting for age, significant cofactors for CIN3+ included current smoking (RR = 1.5), former smoking (RR = 1.8), regular Pap screening (RR = 0.7), current regular condom use (RR = 0.5), and parity ≥ 5 (RR = 1.6, P(trend) for increasing parity = 0.07). However, the parity association differed by age group (≥ 30: RR = 1.8, P(trend) = 0.008; <30: RR = 0.9; P(trend) =.55). CONCLUSION: Subgroup variation by age in the risk of CIN3+ points to the importance of the timing of exposures in relation to CIN3+ detection. IMPACT: Future screening strategies need to consider natural history and secular trends in cofactor prevalence in the pursuit of appropriately sensitive and specific screening tools applied to appropriate age groups.

RESUMO

The female genital tract is rarely the primary site for hematologic malignancies; however, secondary involvement of this anatomic site is common. Primary lymphomas of the gynecologic tract are reported to represent less than 1% of extranodal non-Hodgkin lymphomas (NHL), and the majority of them being B-cell in origin. Diffuse large B-cell lymphoma is the most common subtype, whereas primary extraosseus plasmacytoma of the genital tract is rare.If clinically not suspected, these rare tumors pose a diagnostic challenge both for clinicians and pathologists. Clinical symptoms are often nonspecific and mimic other more common gynecologic malignancies such as squamous cell carcinoma of the cervix or endometrial adenocarcinoma. Although cervico-vaginal (Pap) smear is the primary screening method for cervical squamous cell carcinoma and its precursors, it is far less sensitive for detection of other primary or metastatic malignancies. In this review, we present three cases of hematologic gynecologic malignancies, two cases of primary NHL, and a case of acute myeloid leukemia with relapse as a pelvic mass, all of which were diagnosed on a liquid-based Pap test. In addition, we discuss the morphologic features of differential diagnostic entities of these rare tumors on conventional and liquid-based preparations.

RESUMO

Systemic amyloidosis can occur rarely as multiple masses with replacement of lymph nodes, causing lymphadenopathy and potentially mimicking neoplasms. We report a case of multiple amyloidomas in the inguinal lymph nodes and mediastinum in a 30-yr-old HIV positive woman with remote history of high grade dysplasia. Abundant amorphous material was obtained on fine-needle aspiration, making metastatic squamous cell carcinoma with abundant keratin a potential differential diagnosis. The prudent use of special stains such as Congo red, crystal violet, and immunohistochemical stains for keratin and kappa and beta light chains can be invaluable in helping to clarify the diagnosis. In patients with chronic inflammation, amyloidomas must be considered in the differential diagnosis of mass lesions so the appropriate work-up can be undertaken to minimize this potential pitfall.

RESUMO

Salivary duct carcinoma (SDC) is a high-grade malignant tumor exhibiting aggressive growth with early regional and distant metastasis. We report a case of SDC in a 53-yr-old male with distant metastasis to an inguinal lymph node. The diagnosis of the primary tumor as well as the metastatic lesion was accomplished by fine-needle aspiration (FNA). Aggressive clinical management appears to be the main therapeutic option for long-term survival. Therefore, establishing an accurate preoperative diagnosis by FNA can have both clinical and prognostic relevance.

RESUMO

OBJECTIVE: To retrospectively evaluate cellularity and correlate the presence of columnar cells with specimen interpretation in conventionally prepared anal cytologic smears from an HIV-positive population. STUDY DESIGN: Two cytopathologists and 1 senior cytotechnologist, blinded to the original diagnosis, screened 114 samples from 110 patients collected between 1997 and 2002. One hundred nine males and 1 female were included, age ranging from 23 to 52 years. Discrepancies were reviewed for consensus. The interpretations, cellularity, and presence or absence of columnar cells were noted. The relationships between diagnosis and presence of columnar cells, visible anal lesions, concurrent HIV viral load and CD4+ T-cell counts were assessed. RESULTS: The cytologic findings were as follows: 7, unsatisfactory (6%); 29, negative (25%); 25, atypical squamous cells of undetermined significance (22%); and 53, dysplasia (47%) (42 anal intraepithelial lesion 1 [37%] and 11 anal intraepithelial lesion 2/3 [10%]). Nearly 50% of the smears, 51, showed the presence of columnar cells (45%); 37 of those specimens had some degree of dysplasia (74%). Of the 63 specimens with no columnar cells, 16 (25%) showed dysplasia. Columnar cells were absent from all unsatisfactory specimens. CONCLUSION: A highly significant association between the presence of columnar cells and anal intraepithelial lesion (p<0.001) and a significant association between the presence of columnar cells and atypical cytology when a visible lesion was absent (p=0.0019) were found. No significant relationship was found between the presence/degree of dysplasia and CD4+ T-cell counts or HIV viral load. Lack of clinical follow-up precluded evaluation of the false negative rates in this data set.

RESUMO

BACKGROUND: Many genetic traits common to aggressive breast carcinoma have been identified; yet little is known about the interrelationships of such traits during tumor development, especially in women prone to aggressive cancer. This study examined the expression of four biological markers associated with poor prognosis at each stage of breast cancer progression in primary tumors from women of lower economic status and assessed the relationship between these markers. METHODS: Archived primary breast tumors from 77 patients were assessed by immunohistochemical analysis for expression of human epidermal growth receptor 2 (HER-2), p53, vascular endothelial growth factor (VEGF), and e-cadherin, and the relationships between the expressions of these molecules were studied. RESULTS: Twenty-two (29%) patients had advanced (stage III or IV) disease. HER-2, VEGF, e-cadherin, and p53 signal were positive for 31 (40%), 58 (75%), 63 (82%), and 37 (48%) of patients, respectively. Among the markers tested, only p53 exhibited a significant association between expression and stage of the disease ( P = 0.012). Expression of e-cadherin was positively associated with HER-2 overexpression ( P = 0.004), and high levels of HER-2 occurred with strongly positive e-cadherin tumors. Marginally significant positive associations were observed between HER-2 and p53 signal ( P = 0.06), and between disease stage and e-cadherin expression ( P = 0.08). CONCLUSION: The significant tendency toward expression of e-cadherin in conjunction with HER-2 overexpression in breast cancer is a novel finding. The association of p53 with more advanced stages of cancer emphasizes it as a key participant in metastatic processes in breast cancer. Many genetic traits common to aggressive breast carcinoma have been identified; yet little is known about the interrelationships of such traits during tumor development, especially in women prone to aggressive cancer. This study examined the expression of four biological markers associated with poor prognosis at each stage of breast cancer progression in primary tumors from women of lower economic status and assessed the relationship between these markers.

RESUMO

Galanin is a 29 to 30-amino acid neuropeptide involved in diverse regulatory effects in the central and peripheral nervous systems. Although galanin has been found in paragangliomas and other tumors, its expression has not been studied in carcinoid tumors arising in various locations. Galanin was detected in 62% (15/24) of adrenal pheochromocytomas, 40% (2/5) of jugulotympanic paragangliomas, and 18% (2/11) of carotid body paragangliomas, but was absent in 4 extra-adrenal pheochromocytomas and 3 metastatic or recurrent paragangliomas. All 26 carcinoid tumors were negative. Galanin may have limited utility as a diagnostic marker alone but would be most useful in conjunction with other immunohistochemical markers for the differential diagnosis of neuroendocrine tumors.
