Malignant and Premalignant Lesions of the Esophagus.

Premalignant and malignant prostate lesions: pathologic review.

BACKGROUND High-grade prostatic intraepithelial neoplasia (HGPIN) is currently the only recognized premalignant lesion of prostatic carcinoma. METHODS This review article discusses HGPIN, its link to prostatic adenocarcinoma, and the significance of its presence on needle biopsy. The criteria and clinical impact of the diagnosis of atypical small acinar proliferation on needle biopsy are revi...

Chemoprevention of premalignant and early malignant lesions of the prostate.

Premalignant and malignant lesions of the heterotopic pancreas in the esophagus: a case report and review of the literature.

Heterotopic pancreas is a congenital pathology of the gastrointestinal tract, particularly rare in the esophagus. Both symptomatology and findings during preoperative examinations are non-specific and therefore do not often lead to an accurate diagnosis, which is usually revealed only by histopathological assessment of a resected specimen. We report an unusual case of a patient suffering from s...

Advances in the diagnosis of oral premalignant and malignant lesions.

The diagnosis and treatment of oral premalignant lesions and squamous cell carcinoma are currently based on histopathologic features, site of involvement and stage of disease. Recent advances in techniques for detecting lesions and predicting their progression or recurrence are reviewed here. Adjuncts for detection of lesions and selection of biopsy sites include vital tissue staining (with tol...

Tissue eosinophils as a histopathological marker in oral premalignant and malignant lesions: a histochemical study

Introduction: Although recent studies show the association of eosinophils with different tumors including oral malignancies, the role of eosinophils in premalignant conditions of the oral cavity is not known precisely. Therefore, this study aimed to determine the number of eosinophils in premalignant and malignant conditions of the oral cavity and its role in progression to malignancy. Materia...
