To evaluate the role of ultrasound guided core biopsy in the diagnosis of testicular lesions. To present our institutional experience with ultrasound guided core biopsy of testicular lesions.

Testicular tumours are a heterogeneous group of histopathological entities with different biological behaviours and variable prognosis.1 Although several histological subtypes, such as seminoma, predominate in the appropriate patient population, there are other less common categories, including sex cord stromal tumours and lymphoma. There is an impetus to establish histological diagnosis short of surgical orchidectomy, in certain clinical contexts, including the presence of a single testis, prior orchidectomy, high anaesthetic or surgical risk, and patient preference.2,3,4,5,6,7 Ultrasound guided percutaneous testicular core biopsy has served to be...

Case 1 – Large cell calcifying Sertoli tumour 26-year-old male presented to his general practitioner with 6-month history of right scrotal swelling and intermittent pain. Physical examination was unremarkable. Scrotal ultrasound detected two hyperechoic lesions at the superior pole of the right testis, measuring 9 mm and 5 mm respectively (Figure 1 A-C). There is posterior acoustic shadowing associated with the larger lesion, in keeping with intralesional calcification. Both lesions demonstrate vascularity on doppler assessment. Serological tumour markers were within normal limits. The lesion was...

Percutaneous testicular core biopsy is an established technique that permits a histological diagnosis to be made without requiring an orchidectomy. This is useful in in various situations, including where the imaging findings are indeterminate or discrepant with the clinical assessment and where the suspected pathology does not require orchidectomy (for example, lymphoma or leukaemia). The presence of a single testis, high anaesthetic or surgical risk and patient preference are further indications. The relative non-invasiveness of the technique and suitability to be performed as an outpatient...
