Background: Successful treatment of melanoma depends on early diagnosis, but its varied clinical presentation means that no single noninvasive method or criterion can provide reliable detection in all cases.
Objectives: To determine whether combining sequential dermoscopy imaging with reflectance confocal microscopy (RCM) can improve melanoma detection and reduce the burden of unnecessary excisions.
Methods: We conducted a retrospective study with median follow-up of 25 months.
Purpose: The increasing use of breast-conserving surgery makes it essential to identify biofunctional profiles responsible for the progression of in situ to invasive carcinomas to facilitate the detection of lesions that are most likely to relapse or progress and, thus, to be able to offer patients tailored treatment options. Our objective was to analyse and compare biofunctional profiles in ductal carcinomas in situ (DCIS) and invasive ductal carcinomas (IDC). We also aimed to identify markers in tumor and normal surrounding tissues that may be predictive of locoregional recurrence in patients with DCIS.

Objective: To evaluate whether a diagnosis of CM could be achieved using the classic dermoscopic melanoma-specific criteria, we conducted a retrospective multicenter study of 508 CM samples.
Methods: All the dermoscopic images were analyzed to identify the dermoscopic criteria found in dermoscopically difficult melanomas (DDM) and to examine the possible relation of dermoscopic diagnosis with respect to the difficulty of the dermoscopic diagnosis and the melanoma thickness.
Imatinib mesylate (IM), is a selective and competitive inhibitor of tyrosine kinases, including BCR-ABL, ABL, KIT, and the platelet-derived growth factor receptors (PDGF-R). It binds to the ATP-binding site of the target kinase and prevents the transfer of phosphate from ATP to the tyrosine residues of various substrates. At oral doses of 200-600 mg, the majority of patients with chronic myeloid leukaemia, Philadelphia chromosome-positive acute lymphoblastic leukemia expressing the BCR-ABL fusion protein and gastrointestinal stromal tumours (GIST) achieve a bio-molecular and clinical response, frequently complete, associated with limited toxicity.

Angiogenesis is a multistep process resulting from an ordered set of events and regulated by positive and negative modulators of microvessels growth and by the expression of various proteolytic enzymes.
Materials And Methods: We prospectively evaluated VEGF and microvessels density on tumor specimen and cytosolic levels of uPA and PAI-1.
Current clinical practice guidelines for patients with colorectal polyps are mainly based on the histologic characteristics of their lesions. However, interobserver variability in the assessment of specific polyp characteristics was evaluated in very few studies. The purpose of this study was to evaluate the interobserver agreement of four pathologists in the diagnosis of histologic type of colorectal polyps and in the degree of dysplasia and of infiltrating carcinoma in adenomas.

Study Design: Smears from 187 patients with cytologic diagnoses of ASCUS and histologic or two years' cytologic/colposcopic follow-up were reviewed. When an ASCUS diagnosis was confirmed, it was done strictly on the basis of the morphologic criteria recommended by the Regione Emilia Romagna Screening Protocol in 1997, trying also to subclassify ASCUS into favor reactive or favor neoplasia.
Experimental evidence suggests that tumor growth and progression depend on angiogenesis. In a retrospective study we evaluated the relationship between tumor angiogenesis and survival in patients with NSCLC treated with potentially curative surgery between 1992 and 1997. The study population consisted of 76 patients.

Methods: After exclusion of patients with inflammatory bowel diseases, familial adenomatous polyposis, or any cancer, 3088 eligible consecutive subjects aged 18 to 69 years underwent total colonoscopy in four gastroenterology units.
Background: The validation of epiluminescence microscopy (ELM) for the diagnosis of pigmented skin lesions is conditional on the demonstration of consistent histologic correlates of the ELM patterns. The ELM characteristics of malignant blue nevus (MBN) have never been reported previously.
Objective: To evaluate the histologic counterparts of the ELM features of a case of MBN.
The cytologic, histologic, immunocytochemical and ultrastructural features of 2 cases of hyalinizing trabecular adenoma (HTA) of the thyroid are described. The difficulty of a cytologic diagnosis and the need for an immunohistochemical profile of the lesions for a final histologic diagnosis are emphasized.

The median patient age was 57 years. The median tumor thickness was 1.
