Cooks syndrome is an autosomal dominant ectodermal dysplasia. It is characterized by congenital onychodystrophy and anonychia along with fifth finger brachydactyly, digitalization of the thumb, absent or hypoplastic distal phalanges of hands and feet with normal hair, teeth and sweat glands. Anonychia involving all the 20 digits is a rare occurrence. Here we report a 4 day old male baby with congenital anonychia of all 20 digits along with digitalization of the thumb.

Background: Idiopathic guttate hypomelanosis (IGH) is a common benign acquired leukodermic dermatosis characterized by multiple, discrete, hypopigmented-to-depigmented macules. Various treatment modalities were tried for this condition with varied results. Purpose: This study was conducted to compare the efficacy and safety of fractional carbon dioxide laser and 88% phenol in the treatment of IGH. Methods: A total of 40 patients with five IGH macules on each side were treated with one session of fractional carbon dioxide laser on the right side and a single application of 88% phenol on the left side and were assessed monthly for 3 months. The improvement in pigmentation was graded as ≤25% - poor, 26%–50% - minimal, 51%–75% - good, and >75% - excellent response. Results: A total of 32 patients completed the study. Out of the 160 macules treated with laser, 16 (10%) macules showed an excellent response and 40 (25%) showed a good response, and 40 (25%) and 48 (30%) macules in the phenol group showed excellent and good improvement, respectively. Side effects such as persistent scabbing and ulceration were seen only on the phenol side. Conclusion: Single application of 88% phenol was more efficacious than one session of fractional carbon dioxide laser in inducing pigmentation in IGH macules in this study. However, fractional carbon dioxide laser can be considered a safer alternative modality.
