Objectives: Study the loss or reduction of the cellular adhesion mediated for E-cadherin in oral leukoplakias, oral squamous cell carcinomas and metastatic nodules. Study the loss of continuity of the laminin and collagen IV expression in the epithelial basal membrane from the biological development of the oral leukoplakias and oral carcinomas.

Material And Method: we have studied 124 samples of patient pays leukoplakias and oral carcinomas with diverse diagnosis that embrace from normal epithelium (13 samples), mild dysplasias (2), moderate dysplasias (12), in situ carcinomas (13), microinvasive carcinomas (11) oral squamous cell carcinomas (64 samples) and metastatic nodules (9).

Objectives: We intend to know the protein expression of genetic alterations that take place in the early stages in the field cancerization of oral cavity in our means as well as to study the cellular proliferation by means of Ki-67 and the protein product expression of p53 to value if the alterations in the protein products expression of these markers happen in a sequential pathway through the different stages in the field cancerization of oral cavity.

Materials And Methods: A study was made by immunohistochemistry on 53 patients that presented lesions of oral leukoplaquia, assisted by the ENT service at University Hospital of Salamanca, from 1.990 up to 2000.

Objective: We report a case of fibromatous periorchitis, a rare entity that may have differential diagnosis problems with other lesions.

Methods: Our patient underwent a surgical procedure with resection of the tunica vaginalis testis after intraoperative histological evaluation.

Results: Findings observed in both intraoperative biopsy and specimen histopathological study were key for diagnosis.

Objective: To report an uncommon case of idiopathic calcinosis of the scrotum.

Methods/results: A case of idiopathic scrotal calcinosis in a 50-year-old male who presented with multiple hard masses in the scrotum is described. Cytological (fine needle aspiration) and histological (biopsy and resection) analyses of these lesions were performed.
