Background: Cardiofaciocutaneous syndrome (CFCS) is a rare autosomal dominant (AD) condition characterized by cardiac abnormalities, a distinctive craniofacial appearance and short stature. Endocrine manifestations include GH deficiency and precocious puberty. CFCS is part of the RASopathy group including Noonan, LEOPARD, and Costello syndromes.

Background: Carney complex (CNC) is a rare multi endocrine neoplasia syndrome associated with endocrine and non-endocrine tumours. Three types of testicular tumour have been described; large cell calcifying Sertoli tumours (LCCST), Leydig cell tumours and testicular tumours of adrenal origin. LCCST is a rare benign stromal tumour, which has been observed in 41% of males affected with CNC, usually appearing in the first decade of life. It can be hormonally active, presenting wi...
