..Verrucous carcinoma of the uterine cervix is rare. Cytology is thought not to be helpful in the diagnosis of this lesion due to its bland morphology. The cytologic features of this lesion remain poorly defined...

..In the era of HAART, HIV-infected patients with malignancy--particularly those who have robust CD4+ T-cell counts and well-controlled HIV viral loads--should be treated similarly to their HIV-negative counterparts...

..This review focuses on these emerging targets in the treatment of patients with KS and also highlights important clinicopathologic characteristics...

..His back pain subsided, lymphadenopathy regressed, and he became KSHV/HHV8 negative. Albeit a rare condition, Castleman's disease should always be considered in immunocompromised patients suspected of having lymphoma...

..These promising results demonstrate that inhibition of the c-kit and/or PDGF receptors may represent an effective strategy for treating KS...

..Squamous differentiation may serve as a precursor lesion for squamous neoplasia of the colorectum...

..KS regression has not been well characterized histologically. Therefore, this study was undertaken to characterize the histopathology of pharmacologically induced regressed cutaneous KS...

..This paper reviews the literature on the use of IHC in the study of KS...

....

..This study explores the value of GPC3 expression in liver fine-needle aspirates (FNAs) by immunocytochemistry (ICC), and compares its sensitivity and staining intensity with that of IHC...

..In problematic cases, immunohistochemical staining with thyroglobulin and thyroid transcription factor-1 may be required to establish the diagnosis...

..Oral involvement is a common manifestation of acquired immunodeficiency syndrome related Kaposi's sarcoma, and it occurs in approximately one-third of afflicted patients...

..We also observed that in contrast to some in vitro studies, the markedly elevated levels of beta-subunit of human chorionic gonadotropin in this patient did not have any apparent inhibitory effect on viral replication...

..An awareness of this entity and its potential to mimic these more aggressive neoplasms is essential for accurate diagnosis and to avoid over-treatment...

..The behavior of this circumventricular organ lymphoma was comparable to both peripheral and primary central nervous system lymphomas...

..Primary KS of the subcutaneous tissue is an exceptional manifestation of this low-grade vascular neoplasm...

..The aim of this study was to characterize the clinicopathologic findings and outcome in a series of HIV-infected patients diagnosed and treated for colon adenocarcinoma...

....

..Staining for fascin and JunB provides a basis for distinguishing NLPHL from LRCHL and offers an alternative to other antibody profiles...

..Although most causes of breast enlargement in HIV-infected men are likely to be benign, malignancies other than carcinoma are of concern...

..Paraprotein interference in automated chemistry is uncommon. We describe 2 patients with paraproteinemia and elevated total bilirubin levels measured erroneously using the Roche total bilirubin assay...

..This case report serves as a cautionary note regarding the use of potentially oncogenic recombinant human growth hormone therapy to treat human immunodeficiency virus-positive persons...

..Our aim was to describe the risk factors, clinical findings, pathology, and response to therapy of RCC in patients infected with HIV...

..The scope of this review is to present contemporary knowledge about the epidemiology, virology, and immunology of Kaposi sarcoma-associated herpesvirus and to highlight several key oncogene products that may be targets for chemotherapy...

..With the growing problem of non-AIDS-defining cancers in the current era of HAART, clinicians should be aware that skin lesions in the HIV-infected individual might represent metastatic disease...
