Management of incompletely excised nonaggressive BCCs (nodular or superficial types) is still a matter of debate. Previously reported studies have shown recurrence in < 10% of nonaggressive incompletely excised BCCs. Our study showed that rare recurrences of these initially nonaggressive BCCs showed an aggressive component in 20% of cases. These results suggest that initially nonaggressive incompletely excised BCCs do not require re-excision except if they are located in sites with a poor prognosis.

Previous case reports and the results of this study suggest a real link between beta-blockers and aphthous ulcers. Our study did not confirm a role of other drugs but a few interesting case reports with positive reintroduction have to be considered. These results could be beneficial for patients, as healing may occur when the incriminated drug is discontinued.

Bier's spots are asymptomatic and permanent white macules, standing on a cyanotic background. These spots are associated with venous stasis and usually appear in physiological conditions. We report the case of a 47-year-old woman with a 2-year history of systemic scleroderma, who developed Bier's white spots associated with a vascular and renal crisis. Interestingly, these spots appeared with the crisis, and disappeared with the treatment and resolution of the crisis. They are probably a result of anatomical and functional damage to the small vessels of the skin. The pathophysiology in the skin is probably the same as that which happens in renal vessels during scleroderma renal crisis.

Oral nicorandil-induced lesions are not aphthous ulcers. We propose that at this stage of our knowledge, oral nicorandil-induced ulcer is the most suitable terminology.
