[Bullosis diabeticorum]

Three cases of Bullosis Diabeticorum, entity described by Rocca and Pereyra, are reported by the authors. The review of the published literature after the original article shows the importance of recognizing these symptoms for the diagnosis of an occult diabetes. The most outstanding features of the studied cases were: a) the bullosis traumatica present in the 3 observations; b) the finding of an unknown diabetes in two of the three patients; c) the association with stellate pseudoscars. The histopathologic findings were similar in all three patients.
