To the Editor,

We report on a 32-year-old male patient who presented with a retroperitoneal mass. He pre­sented with complaints of left loin pain and fever. He was diagnosed to have acute pyelo­nephritis and treated with antibiotics. However, his general condition deteriorated, he developed nausea, vomiting, chills and severe loin pain. An ultrasound scan of the abdomen was per­formed which showed normal kidneys but a large retroperitoneal mass measuring 17 Χ 8 cm at the level of the lower pole of the left kidney [Figure 1]. [1]

Physical re-examination revealed a small left testis which was located at the level of external ring; this was tender and it was difficult to exclude a small mass arising from it. An ultra­sound scan of the testis showed a small hypo­echoic area which raised the suspicion of a testicular tumor. [2] A CT scan of the abdomen confirmed the presence of the retroperitoneal mass measuring 17 Χ 8 cm located at the level of lower pole of the left testis [Figure 2].

The patient was admitted to the hospital; la­boratory testes showed increased white blood cell count, elevated ESR and alkaline phospha­tase. Tumor markers such as alfa feto protein and beta HCG were normal. He was treated symptomatically with intravenous antibiotics following which his general status improved and he underwent a left radical orchidectomy. [3],[4] Gross description revealed a white nodule mea­suring 1.5 Χ 1 cm; microscopic findings showed cellular loose collagenous tissue, hyalinized seminiferous tubules and collection of lympho­cytes and plasma cells. These findings were su­ggestive of a fibrous tumor and the differential diagnosis included testicular scar which may be seen in the presence of retroperitoneal mass (burned out testicular tumor). Surgical removal of the retroperitoneal mass was needed to exclude seminoma and other lesions.

Subsequently, the patent underwent retroperi­toneal exploration; a soft, capsulated mass ex­tending to the renal pedicle and infiltrating into the renal vessels and the lymphatic sac was found [Figure 3], [Figure 4] and [Figure 5]. In view of these fin­dings, a radical nephrectomy was performed. [5],[6] Histopathology of this mass could not confirm a seminoma; however, the immunohistobio­chemical staining for PLAP was positive and the diagnosis was compatible with seminoma.

In conclusion, seminoma and burned out testicular tumor is a rare occurrence and we present this case to draw the attention to the fact that not all testicular lesions have similar presentations.
