[Skin shrinkage study for skin oncologic surgery. Clinical study of 79 cases].

Background: Skin tumors surgery is common and well established. There is discrepancy between recommendations on macroscopic margins to apply and therapeutic decisions taken on histological margins. The purpose of this study is to examine skin shrinkage upon exeresis, then in formalin, to understand the anatomo-clinical discrepancy, which is often found.

[Pathogenic role of Actinomyces apart from actinomycosis. Apropos of 2 cases of acute suppurations with Actinomyces odontolyticus].

The authors report two cases of acute suppurative lesions due to Actinomyces odontolyticus. They point out the fairly high incidence of this pathogen in such conditions, either isolated or more often as part of a mixed flora. Conversely, Actinomyces odontolyticus is only exceptionally recovered in true actinomycosis.
