ABSTRACT
OBJECTIVES: Congenital hypogonadotropic hypogonadism combined with anosmia or hyposmia is considered Kallmann syndrome (KS). It is often accompanied by bone defects. CASE PRESENTATION: Here, we report a girl and her mother with KS caused by a novel mutation in the fibroblast growth factor receptor 1 gene (FGFR1). Interestingly, the daughter presented syndactyly and oligodactyly of the feet. CONCLUSIONS: The presence of bone malformations in a KS patient should direct the geneticist towards a search for specific mutations in FGFR1. Our finding contributes to enrich the spectrum of FGFR1 mutations in patients with KS.

Cushing syndrome (CS) is a rare disease in children, frequently associated with subtle or periodic symptoms that may delay its diagnosis. Weight gain and growth failure, the hallmarks of hypercortisolism in pediatrics, may be inconsistent, especially in ACTH-independent forms of CS. Primary pigmented nodular adrenocortical disease (PPNAD) is the rarest form of ACTH-independent CS, and can be associated with endocrine and nonendocrine tumors, forming the Carney complex (CNC). Recently, phenotype/genotype correlations have been described with particular forms of CNC where PPNAD is isolated or associated only with skin lesions. We present four familial series of CS due to isolated PPNAD, and compare them to available data from the literature. We discuss the clinical and molecular findings, and underline challenges in diagnosing PPNAD in childhood.
