Background: Extragonadal abdominopelvic teratomas in adults are extremely rare, and those in males are exceedingly rare. These masses are most commonly found incidentally and require surgical excision for diagnostic confirmation after a thorough workup. Case Presentation: This is a case report of a 49-year-old male who presented to a urology office with symptoms of hematuria, incidentally, found to have a pelvic mass on computed tomography urogram prompting colorectal surgical evaluation and subsequent laparoscopic complete excision. The clinical presentation, radiographic findings, and histopathological findings are described along with a literature review of extragonadal abdominopelvic mature cystic teratoma, also referred to as a sacrococcygeal teratoma. Discussion: A broad differential diagnosis was generated for this patient with a pelvic mass after complete work-up, consisting of a dermoid or epidermoid cyst, liposarcoma, or sacrococcygeal teratoma. Radiological features can aid in the diagnostic confusion that may present in the adult patient. Conclusion: Albeit rare in the male and adult population, sacrococcygeal teratoma is a plausible differential diagnosis for a pelvic mass. Underrepresented in the literature in regard to guidelines on management, complete surgical excision is the gold standard, with laparoscopy being a reasonable approach.
