Non-melanoma skin cancers presented a significant incidence increase in the last decades, worldwidely. Even though the impact upon mortality is a relatively low one, through the incidence increase, their impact upon the public healthcare systems is a considerable one. In our study, we evaluated 109 cases of skin carcinomas hospitalized during 2012 in the Department of Plastic Surgery of the Emergency Hospital of Pitesti, Romania, for a surgical treatment. The gender distribution showed slight lesion predominance in women, being recorded 56 (51.38%) tumors in women and 53 (48.62%) in men. The highest incidence of skin carcinomas (75.23%) was recorded in the persons aged over 60-year-old. Of 109 cases of skin carcinomas, 80 (73.4%) carcinomas developed on indignant tegument areas, while 29 (26.6%) on premalignant skin lesions (fiberconjunctive papillomas, keratocantomas, keratosic verrucas). The histopathological study highlighted the fact that of 109 skin carcinomas, 87 (79.82%) were basal cell carcinomas and only 22 (20.18%) were squamous cell carcinomas. The immunohistochemical reaction to 34betaE12 cytokeratin was highly positive in the cells of the basal cell carcinomas and well-differentiated squamous cell carcinomas (except for the keratosic pearls) and moderately positive in the moderately differentiated squamous cell carcinoma.

Corpora amylacea (CA) are glycoprotein-based depositions that accumulate in the normal aging brain or consecutively to different neuro-degenerative diseases. Although controversies still exists in what it regards their origins and functions, their morphology is described simply as round basophilic entities based on bi-dimensional observations. The aim of the present study was to evaluate the three-dimensional morphology of these bodies in the brain in normal aging. We utilized here brain tissue from six aged patients, and performed an in-depth stereological analysis of CAs based on series of thin serial sections, and 50 micro-m-thick sections. The thin seriate sections have been counter-stained with Hematoxylin and Eosin, while the thick sections have been immunostained in fluorescence for ubiquitin and GFAP/collagen IV or aquaporin 4. Three-dimensional renderings have been obtained after aligning the serial sections, while high-resolution z-stacks have resulted after deconvolution on the thick sections. More than 70% of all the identified CAs proved to be in fact parts of larger aggregates, where the flattened individual spheroids branched and communicated with other bodies in a complex pattern, and budding of small CAs from larger CAs could be observed. There was a direct correlation between the diameter of the vessels and the number of associated CAs. Astrocyte GFAP and aquaporin 4 signals surrounded CAs, but without any colocalization with the ubiquitin areas, while perivascular CAs were sometimes enclosed in pockets of the basement membranes. In conclusion, as far as we know, this is the first study to describe the three-dimensional branching complexity of corpora amylacea in the brain.
