RESUMO
The reconstruction of facial surgical defects is usually challenging for the dermatologic surgeon. Three different cases of facial defects in which tunneled island flaps were used are reported. In 2 cases, wide defects involving the nasal dorsum and ala were repaired using a nasolabial island flap tunneled through the lateral side of the nose. A tunneled island glabellar flap was used for medial canthus reconstruction in the third case. Despite complex pedicle dissection and frequent trapdoor deformation, tunneled island flaps allow reconstruction of wide defects in a single-staged procedure, camouflaging the scar of the donor area in boundaries of cosmetic units and preserving the facial central symmetry.

Abstract Dyspigmentation along the Blaschko lines is strongly suggestive of a mosaic skin disorder. We report a 9-year-old male patient who presented with swirls and streaks of both hypo and hyperpigmentation involving the entire body. Additionally, he had hypertrichosis, musculoskeletal and minor neurodevelopment abnormalities but no intellectual disability. Cultured fibroblast displayed trisomy 7 mosaicism, which can explain this pigmentary phenotype. Widespread dyspigmentation associated with involvement of other organs should prompt systemic examination to detect additional anomalies and genetic evaluation should be considered, even with normal fetal karyotype.
