Abstract
Intra-abdominal testicular tumors are uncommon in prepubertal children. The present study is a rare case of intra-abdominal testicular yolk sac tumor with elevated Alpha feto protein levels whose diagnosis was confirmed by histopathology and immuniohistochemistry. Serum tumor markers and radiological examination also aids towards the diagnosis of nonpalpable undescended testis. Keywords Undescended testis, Tumor markers
Highlights
Testicular tumors are extremely uncommon in paediatric group, forming 1 to2% of all solid childhood tumors (1)
Pure yolk sac tumor is almost always seen in infants and young children, representing 70% of paediatric germ cell tumors (2)
Testicular tumors in intraabdominal sites can present either as asymptomatic testicular mass detected during evaluation of nonpalpable undescended testis or with symptoms like abdominal pain or lump associated with nausea, vomiting, low grade fever or intraabdominal testicular tumors (4)
Summary
Testicular tumors are extremely uncommon in paediatric group, forming 1 to2% of all solid childhood tumors (1). Pure yolk sac tumor is almost always seen in infants and young children, representing 70% of paediatric germ cell tumors (2). Imprint was taken & smears studied were cellular, consisting of tumor cells arranged in large sheets & microcystic pattern. These cells were round in shape with indistinct cell membrane, moderate amount of cytoplasm and central round to oval nuclei. Diagnosis of pure yolk sac tumor of right testis was made and confirmed by IHC SALL4+ve (3) (Figure 4). This case is presented for its rarity and complete diagnostic workup
