“…There is no gender predominance in the incidence of fetus in fetu, and patients <3 years old account for more than 90% of the cases. However, fetus in fetu can be found in adults [4] and in pregnant women [5] , the oldest patient with fetus in fetu recorded in the literature was 47 years old at diagnosis [6] . Fetus in fetu can parasitize any part of the host's body; however, the abdominal cavity and retroperitoneum are the most common sites [2 , 7 , 8] followed by the sacrococcygeal region and the abdominal wall.…”

“…FIF can be found in various locations of the host twin's body, ranging from the cranial cavity to the sacrococcygeal region. The diagnosis of FIF usually relies on prenatal ultrasound and MRI, but histopathological examination is still necessary for definitive diagnosis 2 . The prognosis of FIF depends on the degree of threat that the parasitic twin poses to the host twin's development and survival.…”

Key Clinical MessageFetus in fetu (FIF) is a rare congenital anomaly that originates from various sites of the host twin's body. The clinical manifestations of FIF are diverse and the location and size of FIF indicate the degree of threat, which may directly affect the prognosis. A 33‐year‐old woman presented at the hospital with an abdominal mass in her fetus. Prenatal ultrasound observed that mass included soft tissue, bone‐like structures, and fluid. Immature cartilage, nerve tissue, muscle tissue, and glands in the parasitic fetus without signs of neoplastic lesions were reported by histological examination. CNV (copy number variation) and WES (whole exome sequencing) did not detect any abnormal mutations. FIF can continue to grow with gestational age or host infant growth. So complete resection is essential for improving the outcome of the host twin. It is also important that long‐term follow‐up is recommended to monitor any residual or recurrent cysts or malignancies.
