Scrotal lipomas are benign tumours rarely seen in clinical practice. They can mimic common affections such as an an inguinoscrotal hernia, varicocele, hydrocele or a testicular tumour. Thus, in many cases, physical examination leads to a correct diagnosis, there are situations that require comprehensive imagistic examinations, to establish the preoperatory nature of the scrotal tumour. A case of 64-year-old male, known with arterial hypertension and gonarthrosis, came to the hospital for a painless scrotal tumour with a fast growth rate in dimensions over the last year. Physical examination detected an elastic, painless, irreducible, irregularly shaped mass of a right scrotal region. The scrotal ultrasound revealed a heterogeneous hyperechoic solid mass with 10x8.1x8cm in dimensions, localized in the right scrotal region. The magnetic resonance imaging (MRI) showed a globular shaped right scrotal tumour mass with well-defined margins, poorly vascularized at the lower pole. Surgery was performed, with excision of a mass about 10cm in major diameter from the right scrotal wall. Postoperative evolution was good, and the histological diagnosis of primary scrotal lipoma was made. One-year follow-up revealed no local relapse.
