The patient elected observation after further workup showed no evidence of metastasis.A repeat ultrasound 3 months later showed interval growth and the patient underwent right radical orchiectomy. Pathology was consistent with pure embryonal carcinoma of the testis. Calcified testicular masses are typically benign but do carry a differential of spermatic granuloma, large-cell calcifying Sertoli cell tumour, trauma, tuberculosis, filariasis, calcified Leydig cell tumour and burned-out testicular tumour.To our knowledge, this is the first case report of pure embryonal carcinoma presenting as a solitary calcified testicular mass.Abstract: Copyright (c) BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.
