The Canadian Prostate Health Council   (Site not responding. Last check: 2007-10-08) Appropriate histopathological interpretation and standardized reporting of prostatic transrectal biopsy specimens are crucial in early diagnosis and monitoring of patients with prostatic neoplasia. This article provides a histopathological perspective focusing on aspects of clinical relevance and includes the following: high-grade prostatic intraepithelial neoplasia and its mimics; glandular (microacinar) proliferations which could be confused with adenocarcinoma; minimal diagnostic criteria of malignancy in minute volume tumor sampling; terminology and reporting of glandular atypical proliferations below the diagnostic threshold of malignancy. Histopathologic effects of three-dimensional conformal external beam radiation therapy on benign and malignant prostate tissues. www.canadian-prostate.com /ver_01/eng/updates/cpv4no35.htm   (6159 words)

Histopathology - Wikipedia, the free encyclopedia It is an important tool of anatomical pathology and is used for accurate diagnosis of cancer and other diseases. Histopathological examination of tissues starts with surgery, biopsy or autopsy. The tissue is removed, and then placed in a fixative which stabilizes the tissues to prevent decay. en.wikipedia.org /wiki/Histopathology   (524 words)

Clinical and histopathological improvement of psoriasis with oral chondroitin sulfate: A serendipitous finding Histopathologically, there was a statistically significant decrease in epidermal thickness, a decrease in the thickness between the stratum basale and the stratum granulosum, a significant improvement of the degree of psoriasis activity, and a decrease in the number of keratinocytes stained with Ki-67. Therefore, in the present study we evaluated the clinical characteristics and histopathological parameters of patients with knee osteoarthritis and psoriasis treated with oral chondroitin sulfate for the amelioration of articular symptoms. More importantly, results of the histopathological study of the skin biopsies showed a statistically significant decrease in epidermal thickness, with a mean difference of 29 percent between pretreatment and post-treatment values, and a decrease in the thickness between the stratum basale and the stratum granulosum, with a mean difference of 31 percent. dermatology.cdlib.org /111/fast_track/chondroitin/verges.html   (2948 words)

Melanoma Histopathological Variants   (Site not responding. Last check: 2007-10-08) Histopathologically, the skin lesion was composed of heavily pigmented neoplastic cells mostly arranged as large sheets, focally also in a nodular growth pattern. Animal type melanoma is a rare histopathologic variant of melanoma characterized by sheets and nodules of heavily pigmented epithelioid melanocytes that involve the entire thickness of the dermis. Histopathologic and immunohistochemical features were compared with known cases of cutaneous metastasis and nodular melanoma in an attempt to differentiate this entity from clinical and pathologic mimics. www.thedoctorsdoctor.com /diseases/melanoma_histology.htm   (12526 words)

Fibrosing Cholestatic Hepatitis   (Site not responding. Last check: 2007-10-08) Overall, the histopathological features are similar, but not identical to, those described for "cholestatic" hepatitis in the general population. In HBV+ recipients, FCH is also characterized by massive expression of hepatitis B core antigen, which is seen in the same hepatocytes that show the degenerative changes such as cell swelling and steatosis and focal necrosis. Histopathological changes that are helpful in making the correct diagnosis are usually quite subtle. tpis.upmc.edu /tpis/liver/ILFChHep.html   (1461 words)

Diagnostic Pathology | Full text | Clinical-histopathological correlation in a case of Coats' disease The eye was enucleated and subsequent histopathological evaluation confirmed the diagnosis of Coats' disease. Therefore, It is crucial for the pathologist to be familiar with the histopathological features of the former, and distinguish it from the latter. Consequently, an enucleation specimen that permits a histopathological study with reference to the basis of the disease is rare. www.diagnosticpathology.org /content/1/1/24   (1526 words)

Arthritis Research & Therapy | Full text | Correlation of histopathological findings and magnetic resonance imaging ... All patients with AS showed different degrees of interstitial bone marrow edema in histopathological analysis: in two patients with AS, interstitial edema was present in 10% of the total bone marrow area, in two patients it was present in 20%, in two patients in 30% and in two patients in 60% (Table 1). There was only a poor correlation between histopathologically observed interstitial edema and inflammatory cell infiltration, and therefore only a poor correlation between cell infiltration and MRI edema, which might explain why some patients with AS can have active disease despite a normal MRI [16]. A first systematic analysis of bone marrow edema in MR images and histopathological analysis was performed in osteoarthritis [15] in which bone marrow edema could be observed in MR images in up to 50 to 68% of patients. arthritis-research.com /content/8/5/R143   (2864 words)

BioMed Central | Full text | Histopathological evaluation of ocular microsporidiosis by different stains We have earlier reported calcofluor white and modified acid fast stain to be the most useful stains for the diagnosis of microsporidial keratitis in corneal scrapings [17], but we wanted to know if these results also applied for tissue sections of patients who underwent penetrating keratoplasty. Histopathological examination of the corneal button has been reported to be instrumental in documenting the first case of ocular microsporidiosis [8] which revealed numerous oval bodies measuring 3–4 microns, that were weakly positive with HandE, PAS and Gram stain. In our experience too, histopathological confirmation with 1% acid fast stain after detection of spores on H and E stained section, of the first case of stromal keratitis due to microsporidia helped increase confidence in the detection of the spores in corneal scrapings. www.biomedcentral.com /1472-6890/6/6   (3987 words)

BENIGN DISORDERS OF THE PROSTATE: A HISTOPATHOLOGICAL STUDY Although the medical literature contains adequate accounts of the pathophysiology of various benign prostatic disorders, it is often necessary to revisit these lesions, to reexamine the relationships between known benign lesions and more sinister, malignant disorders, in the light of new advances in our understanding of the processes. We carried out a histopathological review of prostatic surgical pathology material seen over a seven-year period in our hospital. Therefore, in the light of growing knowledge about prostatic lesions, it is necessary to periodically review known benign lesions in order to re-assess any relationships or impact they may have on malignant or premalignant prostatic disease. www.kfshrc.edu.sa /annals/181/97-086.html   (2783 words)

Relationship of patients' age to histopathological features of breast tumours in BRCA1and BRCA2and mutation-negative ... Our aim was to evaluate the relationship of patients' age to histopathological features of hereditary breast tumours in a series of breast cancer families not selected for age at diagnosis. Simple family history criteria of the strongest predictors (onset of breast cancer under age 40 and presence of ovarian cancer) for a mutation may also provide a rough estimate of a high likelihood of carrying a mutation [27]. However, it would be useful if, besides family history, histopathological markers could also be used to distinguish patients and families likely to carry a BRCA1/2 germline mutation from mutation-negative families and breast cancer patients in general. bmc.ub.uni-potsdam.de /bcr1025/text.htm   (3449 words)
