Teratomas are rare pluripotent embryonic tumours occurring mostly in gonadal organs and pediatric age groups. Mature cystic teratoma in the liver are rare, and to the best of our knowledge, only a dozen cases in adults have been published in the literature. We present a 27-year-old female who had a history of loss of appetite and mild abdominal distention. Computed Tomography revealed a liver mass suggestive of teratoma. The patient underwent elective surgery, and the diagnosis of mature cystic liver teratoma was confirmed histologically. Measuring 23 cm in a longitudinal axis, the patient had an uneventful post-operative evolution and was discharged on day eight. Teratomas in the liver are a rare finding, especially in adults, mostly due to their asymptomatic evolution. Due to the possibility of malignant transformation, complete surgical resection remains the best treatment option.
