RESUMO
Intense pulsed light (IPL) systems have evolved since they were introduced into medical practice 20 years ago. Pulsed light is noncoherent, noncollimated, polychromatic light energy emitted at different wavelengths that target specific chromophores. This selective targeting capability makes IPL a versatile therapy with many applications, from the treatment of pigmented or vascular lesions to hair removal and skin rejuvenation. Its large spot size ensures a high skin coverage rate. The nonablative nature of IPL makes it an increasingly attractive alternative for patients unwilling to accept the adverse effects associated with other procedures, which additionally require prolonged absence from work and social activities. In many cases, IPL is similar to laser therapy in effectiveness, and its versatility, convenience, and safety will lead to an expanded range of applications and possibilities in coming years.

Idiopathic facial aseptic granuloma (IFAG) is a condition that is commonly encountered in clinical practice, but is rarely reported. It appears in childhood and its pathogenesis is still unknown. It has a benign course with resolution within a few months without aggressive treatment. Microbiological tests are negative and histological findings are nonspecific. It is possible that this condition is part of the spectrum of granulomatous rosacea in childhood. We present two cases in which diagnosis of IFAG was established and resolved without sequelae following topical antibiotic treatment.

Local anesthetics are widely used in clinical practice, and adverse effects are not uncommon. Delayed hypersensitivity reactions are among the most common effects, but immediate-type reactions may also occur. Patch testing should be considered in patients with hypersensitivity reactions. We present a case of allergic contact dermatitis to benzocaine that was detected incidentally by patch testing and highlight the importance of correctly interpreting patch test results when there are concomitant positive reactions.
