1 Testicular Sarcoid Case presentation Dr. Kirsty Cattle, Mr. S. Datta University Hospital of Wales

2 Case 1 34 year old male 34 year old male PC: slight discomfort and swelling of both testes for 2-3 years, worse on R for past 2 months PC: slight discomfort and swelling of both testes for 2-3 years, worse on R for past 2 months Otherwise fit and well Otherwise fit and well O/E: normal scrotal examination, small palpable bilateral inguinal lymph nodes, axillae and cervical areas clear O/E: normal scrotal examination, small palpable bilateral inguinal lymph nodes, axillae and cervical areas clear

3 Investigations: Investigations: USS scrotum and abdomen: multiple hypoechoic areas in both testes, para-aortic lymphadenopathy USS scrotum and abdomen: multiple hypoechoic areas in both testes, para-aortic lymphadenopathy CXR clear CXR clear Open inguinal lymph node biopsy and right testicular tru-cut: non-caseous granulomas in lymph node, no acid fast bacilli, epididymal tissue only on tru-cut Open inguinal lymph node biopsy and right testicular tru-cut: non-caseous granulomas in lymph node, no acid fast bacilli, epididymal tissue only on tru-cut

4 CT abdomen + pelvis: some small para-aortic lymph nodes only CT abdomen + pelvis: some small para-aortic lymph nodes only ACE elevated at 84 units/l (normal 20-54), 24 hour urinary calcium and bone profile normal ACE elevated at 84 units/l (normal 20-54), 24 hour urinary calcium and bone profile normal Referred to chest physician: Referred to chest physician: Differential diagnoses: sarcoid, tuberculosis, or cat scratch fever (keeps ferrets and cats) Differential diagnoses: sarcoid, tuberculosis, or cat scratch fever (keeps ferrets and cats) Tuberculin test Tuberculin test Discharged as feeling completely well Discharged as feeling completely well

5 Case 2 27 year old white male 27 year old white male Presented with a painful lump in his right testis Presented with a painful lump in his right testis PMH: bilateral anterior uveitis 8 months earlier PMH: bilateral anterior uveitis 8 months earlier O/E: bilateral “shotty” feeling lumps on both testes O/E: bilateral “shotty” feeling lumps on both testes USS scrotum: multiple hypoechoic lesions within both testes USS scrotum: multiple hypoechoic lesions within both testes

7 Open trans-scrotal biopsies were taken Open trans-scrotal biopsies were taken Histology showed testicular tissue 90% replaced with non caseating granulomas with multi- nucleated giant cells consistent with sarcoidosis. No evidence of spermatogenesis in residual seminiferous tubules.

9 One month later: developed hearing loss, facial numbness and paraesthesia, headaches One month later: developed hearing loss, facial numbness and paraesthesia, headaches Investigated for neurosarcoid: Investigated for neurosarcoid: MRI scanning – normal MRI scanning – normal Baseline anterior pituitary function – normal Baseline anterior pituitary function – normal

10 Followed up by endocrinologist: Followed up by endocrinologist: Testosterone – 8 nmol/l (normal range 9-40) Testosterone – 8 nmol/l (normal range 9-40) Elevated gonadotrophins Elevated gonadotrophins Azoospermia on semenalysis Azoospermia on semenalysis Therapy: Therapy: Prednisolone 60mg daily reducing regime Prednisolone 60mg daily reducing regime Alendronate once weekly Alendronate once weekly Testosterone replacement Testosterone replacement

11 Progress: Progress: Well, in full time employment Well, in full time employment Semenalysis: count 1.2m/ml, motility 75% after 6/12 of steroids Semenalysis: count 1.2m/ml, motility 75% after 6/12 of steroids Improvement in neurological symptoms of headaches and paraesthesia Improvement in neurological symptoms of headaches and paraesthesia Now off steroids Now off steroids

12 Sarcoidosis Multisystem granulomatous disorder Multisystem granulomatous disorder Histological diagnosis: non-caseating granulomas Histological diagnosis: non-caseating granulomas Black : white ratio 20:1 Black : white ratio 20:1 Female : male ratio 10:1 Female : male ratio 10:1 Presentation: bilateral hilar lymphadenopathy on chest radiograph, respiratory symptoms, skin lesions, anterior uveitis Presentation: bilateral hilar lymphadenopathy on chest radiograph, respiratory symptoms, skin lesions, anterior uveitis

13 Scrotal sarcoid 70% affects epididymis 70% affects epididymis Epididymal sarcoid: Epididymal sarcoid: Recurrent painful epididymitis Recurrent painful epididymitis Ductal obstruction causing oligospermia and infertility Ductal obstruction causing oligospermia and infertility

14 Testicular sarcoid: Testicular sarcoid: Primary gonadal dysfunction, causing low testosterone levels and resultant loss of secondary sexual characteristics Primary gonadal dysfunction, causing low testosterone levels and resultant loss of secondary sexual characteristics Leydig cell dysfunction, causing disruption of spermatogenesis Leydig cell dysfunction, causing disruption of spermatogenesis Unilateral testicular swelling due to sarcoid is clinically and radiologically indistinguishable from a neoplastic cause Unilateral testicular swelling due to sarcoid is clinically and radiologically indistinguishable from a neoplastic cause
