Misdiagnosing a seminoma as an inguinal hernia is an uncommon medical concern. A 22-year-old male presented with an enlarged, painless lump in the right scrotum above the right testis. He had previously been given a diagnosis of inguinal hernia by a general practitioner in a rural area two years ago. Pelvic trauma had never occurred before. Scrotal ultrasonography revealed that his right testis was hypoechoic, asymmetrical, and solidly enlarged. A radical orchiectomy was done to remove the tumor. A histological examination of the mass confirmed the diagnosis of classical seminoma. Six months later, the patient had no complications and was in good condition. General practitioners must be more mindful of this tumor, particularly its presentation, since seminoma tumors might be misdiagnosed as an inguinal hernia. This is necessary to preserve the reproductive organs and achieve good outcomes.
