Unveiling the Uncommon: A Rare Encounter of Solid Pseudopapillary Neoplasm of Testis

Solid Pseudopapillary Neoplasm (SPN) of the pancreas is a rare and intriguing entity within the spectrum of pancreatic neoplasms, accounting for approximately 1-2% of all pancreatic tumours. Extra-pancreatic SPN is even rarer. It has been reported in locations such as the mesocolon, ovary, retroperitoneum, paratesticular region, and others. A case of extra-pancreatic SPN of the testis was reported in the Department of Pathology, Government Medical College, Kottayam, in 2024. A 48-year-old male presented with a right hemiscrotal swelling of one-year duration, with normal serum tumour markers and laboratory investigations. Radiological evaluation (MRI and Doppler ultrasound) suggested a neoplastic aetiology, and the patient underwent high inguinal orchidectomy. Histopathological examination revealed morphological features consistent with SPN, supported by immunohistochemical findings.
