[Contiguous gene deletion syndrome in Xp21: the association between glycerol kinase deficiency, congenital suprarenal hypoplasia and Duchenne's muscular dystrophy].

Introduction: Complex glycerol kinase (GK) deficiency is a contiguous deletion of genes in Xp21 with loss of the locus for GK, for congenital adrenal hypoplasia (AHC) and/or for Duchenne's muscular dystrophy (DMD). We report the case of a 7-year-old patient with this rare disease.

Case Report: Our patient was a full-term male, with normal gestation and delivery, and no relevant family history.

[Subcutaneous nodules in children: subcutaneous granuloma annulare].

Subcutaneous granuloma annulare is a benign, chronic inflammatory lesion located usually at scalp or extremities and typical of childhood. Its etiology is unknown and no link with systemic diseases has been found. A thorough clinical history and normality at complementary tests are enough for its identification.
