Zosteriform spiradenoma with spiradenocarcinoma: A rare entity

Eccrine spiradenoma (ES) is an uncommon well-differentiated benign tumor originating from the sweat glands. It usually occurs as a single lesion in adults. Multiple ES in a linear or zosteriform distribution are rare. Spiradenomacarcinoma is an extremely rare tumor, which develops in an existing benign spiradenoma of several years of duration. We report a case of a 23-year-old- female patient with multiple spiradenomas arranged in zosteriform pattern and malignant transformation occurred in one of the lesions over a period of 10 years

E Pluribus Unum? Authorities' Design in Financial Supervision: Trends and Determinants

This paper presents an analysis of recent trends and determinants in the architectures of financial supervision, focused on the authorities design. We propose a path dependence approach to study the single authority versus multi-authority dilemma, considering the level of financial supervision consolidation as the dependent variable. In particular, in a movement towards full consolidation in supervision, one can think of two sharp alternatives: a monopolist central bank or a pure single financial authority. Given that the degree of supervision consolidation seems to be inversely correlated with central bank involvement in supervision itself, the paper sheds light on the possible explanation of this trade-off. The trade off is tested using Probit techniques with a sample of 68 countries. Copyright Springer Science + Business Media, Inc. 2006financial supervision, single authority, central bank,
