RESUMEN
PURPOSE: In this observational descriptive study we reviewed the histology and the clinical records of 130 patients with LS involving the male genitalia to determine the presence of premalignant or malignant lesions. MATERIALS AND METHODS: A total of 130 male patients (from 1991 to 2001) with genital LS were treated at our centers. Mean patient age at diagnosis was 42.5 years. In all patients with a clinical diagnosis of LS, the histology was reexamined to look for evidence of LS, applying strict histological criteria. All cases of histologically proven epithelial malignancy, namely SCC, VC and EQ, were reviewed to confirm the presence of neoplastic changes and ascertain the degree of SCC differentiation. RESULTS: Of 130 men 11 (8.4%) with genital LS showed premalignant or malignant histopathological features including 7 (64%) with SCC, 2 (18%) with VC, 1 (9%) with EQ and 1 (9%) with SCC associated with VC. In 6 of 11 patients (55%) the histological study showed the presence of epithelial dysplasia. CONCLUSIONS: Survival of patients with penile carcinoma depends on early diagnosis and treatment, and all patients with genital LS should be observed closely to detect the development of neoplastic or preneoplastic lesions as early as possible.

The purpose of this study was to establish the interlaboratory reproducibility of immunocytochemical analysis of oestrogen (ER) and progesterone (PR) expression and Mib1 growth fraction on fine needle aspiration (FNA) smears. A set of 44 immunostained slides for ER, PR and Mib1 were randomly selected from the archives of the Center for the Study and Prevention of Cancer (CSPO) of Florence, Italy, and submitted for reading to 6 Italian laboratories. The generalized kappa statistic was used as an indicator of agreement among the six laboratories. A good correlation for ER and PR was evident. For Mib1 the results showed some discrepancies. In addition to adequate standardization of procedures, these data confirm that the reliability of the immunocytochemistry is strictly linked to accurate analysis of the results.
