Sex cord / gonadal stromal tumours I.A. <strong>Sesterhenn</strong> J. Cheville P.J. Woodward I. Damjanov G.K. Jacobsen M. Nistal R. Paniagua A.A. Renshaw Sex cord / gonadal stromal tumours, pure forms Included in this category are Leydig cell tumours, Sertoli cell tumours, granulosa cell tumours and tumours of the thecoma/fibroma group. These tumours constitute about 4-6% of adult testicular tumours and over 30% of testicular tumours in infants and children. The name given to this group does not indicate a preference for any particular concept of testicular embryogenesis. As with the germ cell tumours, the aim throughout this section is to closely parallel the WHO terminology and classification of ovarian tumours. About 10% of these tumours, almost always in adults, metastasize. However, it may not be possible on histological grounds to forecast their behaviour. Some of these tumours occur in androgen insensitivity syndrome (AIS) and adrenogenital syndrome (AGS) and should be classified under tumour-like lesions. Leydig cell tumour Definition A tumour composed of elements recapitulating normal development and evolution of Leydig cells. ICD-O codes Leydig cell tumour 8650/1 Malignant Leydig cell tumour 8650/3 Fig. 4.61 Leydig cell tumour. Synonym Interstitial cell tumour. Epidemiology Leydig cell tumours account for 1-3% of testicular tumours {1318,1800,2664}. In infants and children, they constitute about 3% of testis tumours and 14% of stromal tumours {2366}. Unlike germ cell tumours, there is no race predilection {1800}. Occasionally, Leydig cell tumours are seen in patients with Klinefelter syndrome {1800,2664}. About 5-10% of patients have a history of cryptorchidism {1318}. Clinical features Signs and symptoms The tumour is most common in the 3 rd to 6 th decade and in children between 3 and 9 years {1318,2366}. Painless testicular enlargement is the most common presentation. Gynecomastia is seen in about 30% of patients either as a presenting feature or at clinical evaluation for a testicular mass {979,2664}. Libido A B Fig. 4.62 Leydig cell tumour. A Typical morphological appearance. B Leydig cell tumour. Note the Reinke crystals. and potency may be compromized. In children, precocious puberty is not uncommon {2831}. Leydig cell tumours produce steroids, particularly testosterone, androstenedione and dehydroepi-androsterone {298,2831}. Serum estrogen and estradiol levels may be elevated {828}. The latter may be associated with low testosterone and follicle stimulating hormone levels {213,1738}. Progesterone, urinary pregnanediol and urinary 17-ketosteroid levels may be elevated {535,2052}. Bilaterality is rare {1318,1800}. A Fig. 4.63 Leydig cell tumour. A Leydig cell tumour with cords of tumour cells. B Tumour cells stain intensely for inhibin, which is also present to a lesser extend in adjacent tubules. B Imaging Leydig cell tumours are generally well defined, hypoechoic, small solid masses but may show cystic areas, haemorrhage or necrosis. The sonographic appearance is quite variable and is indistinguishable from germ cell tumours. There are no sonographic criteria, which can differentiate benign from malignant Leydig cell tumours and orchiectomy is required. 250 Tumours of the testis and paratesticular tissue
