An increasing number of patients who are receiving anticoagulation or antiplatelet therapy require cutaneous surgery. Such pharmacotherapies are usually suspended based on experience in gynecologic, thoracic, and abdominal surgery. However, this practice may increase the risk of suffering a thromboembolic event. We review perioperative management of anticoagulant and antiplatelet therapy, complications associated with suspending therapy, and side effects.

Review Comparative Study[Pityriasis versicolor and the yeasts of genus Malassezia].
Although pityriasis versicolor is the only human disease for which Malassezia yeasts have been fully established as pathogens, it is still not clear which species are implicated. Most studies carried out in recent years support our hypothesis - proposed in 1999 - that Malassezia globosa is the predominant species in pityriasis versicolor lesions, at least in temperate climates. Confirmation of this hypothesis could help us understand the conditions, as yet unclear, that induce transformation of this yeast from the saprophytic form present in healthy skin to the parasitic form, characterized by the formation of pseudomycelium, and could also guide therapy. In addition, isolation of another species, Malassezia furfur, which seems to be predominant in the tropics, raises the possibility of a second etiologic agent confined to certain areas, as occurs with some other human mycoses.

Case Reports[Patient with generalized guttate morphea and lichen sclerosus et atrophicus].
Generalized guttate morphea is a very uncommon clinical entity, and few reports are available in the literature. We report the case of a 7-year-old boy who first attended our clinic in 1990 with guttate morphea on the trunk and upper limbs. These lesions were associated with plaque morphea on his right foot. ⋯ Clinically and histopathologically, they resembled lichen sclerosus et atrophicus. Given that morphea and lichen sclerosus et atrophicus share certain clinical and pathologic characteristics, some authors believe that these entities may be related or even different presentations of the same disease. The most noteworthy aspect of our case is the type of morphea, as we were unable to find equivalent examples in the literature.
