Genital and perianal herpetic ulcers are common in HIV-infected patients and chronic mucocutaneous ulcers persisting for more than 1 month are the hallmark of active AIDS status. However, atypical clinical manifestations of herpes simplex virus (HSV) may occur in immunocompromised patients presenting as tumor-like nodules or condylomatous or hypertrophic lesions, rather than a classic ulcer. Such unusual presentations raise the risk of misdiagnosis and a delay in appropriate treatment. Here we describe nine immunocompromised HIV-positive patients with CD 4 count ranging from 14-362/mm(3) (mean 170/mm(3)), with unusual tumoral presentation of anogenital herpes. There were six male and three female patients with AIDS with mean duration of HIV infection of 14 years. All of the patients had history of highly active antiretroviral therapy (HAART), with five patients compliant with the therapy at the time of biopsy. Six patients presented with scrotal or vulvar masses and three with perianal nodules. Five patients had adjacent human papilloma virus (HPV)-related lesions. Prior to excision, herpetic lesion was clinically suspected in only three patients and in the rest of the patients a malignant growth was the main clinical concern. The predominant histopathologic finding was dense dermal plasmacytic infiltration with overlying pseudoepitheliomatous hyperplasia, superficial ulcers and classic herpetic inclusions. Patients with AIDS may experience excessive number and size of both primary and reactivated herpetic lesions. The tumoral presentations discussed here are less common, but are often clinically misdiagnosed. It is important to be aware of these unusual presentations to provide a correct diagnosis and prompt, effective treatment for HSV. Several studies suggest that aggressive treatment of HSV in combination with HAART therapy provides a significant survival benefit. Pathobiology mechanisms of unusual and exaggerated tumor-like inflammatory response are not completely elucidated.

While infection with high-risk HPV is the most important risk factor for cervical cancer, HPV alone is insufficient. Our purpose was to identify viral and epidemiologic factors associated with cervical disease in HPV-16 DNA-positive women referred to colposcopy. We used a standardized interview to collect epidemiologic data from consenting women. Total nucleic acids from exfoliated cervical cells were used for all viral assays (HPV detection and typing using L1 consensus PCR with line probe hybridization, variant classification by sequencing, viral load and transcript copy determination by quantitative PCR and transcript pattern by nested RT-PCR). Cervical disease was based on colposcopic biopsy. Logistic regression was used to calculate ORs with 95% CIs. There were 115 HPV-16 positive women among 839 enrollees. By univariate analyses, age >25 years (OR = 3.05, 95% CI 1.20-7.76), smoking (OR = 3.0, 95% CI 1.19-7.56), high viral load (OR = 5.27, 95% CI 2.05-13.60), detection of both E6 and E6*I transcripts (OR = 10.0, 95% CI 2.1-47.58) and high transcript copies (OR = 5.56, 95% CI 2.05-13.60) were significant risk factors for CIN III with reference to No CIN/CIN I. Less than a third of the women (31.5%) had prototype HPV-16 detected, and variants showed no association with disease, viral load or transcription. Viral DNA and transcript copies were highly correlated, and the ratio of transcript copies to DNA copies was not changed with disease status. While viral load, transcript copies and transcript pattern were statistically associated with CIN III, none of these measures effectively discriminated between HPV-16 women with disease requiring treatment and those who could be followed. Cellular proliferation and differentiation pathways affected by HPV should be investigated as biomarkers for cervical cancer screening.

However, it is clear that HPV alone is insufficient to cause cancer. Most HPV infections are transient and associated with no lesions or spontaneously regressing low-grade precancerous lesions. Factors that facilitate HPV oncogenesis are important targets for early detection, therapeutic intervention and monitoring the response to therapy. Identifying these factors may be difficult because of the high baseline risk associated with HPV infection. One approach is to identify risk factors for cervical disease in groups with high-risk HPV infection.Our purpose was to examine viral and epidemiologic factors associated with biopsy-confirmed cervical disease in HPV-16 DNA-positive women referred to colposcopy. Viral characteristics other than simple HPV type may be associated with disease and reflect increased virulence or increased host susceptibility. We examined the genotype variants of HPV-16, HPV DNA copy number (viral load), patt...

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 liquidbased Pap test. In addition, we discuss the morphologic features of differential diagnostic entities of these rare tumors on conventional and liquid-based preparations.
