Organ-sparing surgery for large cell calcifying Sertoli cell tumour in a patient with Carney complex.

Carney complex is a rare genetic disease characterised by a complex of myxomas, spotty pigmentation and endocrine overactivity. At diagnosis, about one-third of male patients presents with testicular tumours, namely large cell calcifying Sertoli cell tumours, which are often multicentric and/or bilateral and have a low malignant potential. Although radical orchiectomy is the gold standard for the treatment of testicular neoplasms, a conservative approach with partial orchiectomy or tumourectomy may be the best treatment option for these patients, allowing the preservation of endocrine function, fertility and body image. We present a case of a 19-year-old man with a known history of Carney complex with early identification of a small testicular tumour treated with organ-sparing surgery.
