Ileal teratoma with multiple congenital anomalies

Gastrointestinal teratoma is a rare neoplasm seen most often as gastric teratoma in children. This is a report of a neonate who had a ruptured omphalocele, ileal teratoma, and multiple associated anomalies. According to an English-language literature review this is the first case report of an ileal teratoma. J Pediatr Surg 35:1370-1371. Copyright © 2000 by W.B. Saunders Company.

Gastric teratomas are rare and mostly benign. They frequently become evident as a palpable abdominal mass. A malignant, aggressive solid tumor must be excluded. We present a 6-month-old male infant with a history of bleeding of the upper gastrointestinal tract. After in toto excision the histopathology was that of a benign gastric teratoma. Our method of reading the diagnosis and the subsequent therapy are described.

Malignant gastric teratoma: case report

Gastric teratomas are rare and usually benign. A 4 month old boy presented with an abdominal mass and computed tomographic and ultrasound examination demonstrated a large multi-loculated tumour which was totally excised. The pathological diagnosis was of a malignant gastric teratoma and 12-month follow-up was uneventful.

Abdominal teratomas in children.

Seventeen cases of abdominal teratoma were studied retrospectively. These patients had been diagnosed at Cathay General Hospital from 1978 to 1993. The male to female ratio was 9:8, the range of age at diagnosis was from 2 days to 13 years. The chief complaints were palpable abdominal mass in 13 patients (76%) and abdominal distention in 7 (41%). Fifteen teratomas were located in the retroperitonium; also, 1 of the 17 had gastric teratoma and another, a tumor originating from an undescended testes. The tumors were resected in all patients. Postoperative courses were smooth except for one patient, who died suddenly on the day following surgery. No further specific management was needed because the pathologic findings were all benign in nature. Ultrasonography is of benefit in locating, as well as diagnosing, abdominal teratoma. Surgical excision is curative for the majority of cases. Long term follow-up is necessary, in consideration of the rare chance of recurrence.

Gastric teratoma: The sixth reported case in a female infant

Teratomas are derived from tissues of all three germ layers. Gastric teratomas are rare and represent 1% of all teratomas in boys. This report describes the sixth occurrence of gastric teratoma in a girl.

Longitudinal observations on 15 children with Wiedemann‐Beckwith syndrome

We conducted a follow-up study on 15 patients with Wiedemann-Beckwith syndrome (WBS) to further clarify major and minor diagnostic clinical characteristics and longterm expectations for growth and development. We found patients with WBS tended to have polyhydramnios with large placentas which were almost twice normal placental weight. The large fetal size and polyhydramnios often resulted in early delivery with occasional perinatal mortality (three cases). Increased placental size, with associated polyhydramnios resulting in excessive umbilical cord length, may be useful in suspecting WBS prior to delivery, thereby facilitating perinatal management. The presence of abdominal wall defects and/or macroglossia may help to confirm the diagnosis. At birth, patients were almost 2 standard deviations above the expected mean for gestational age, length, and weight. This trend continued through early childhood and then excessive size became less dramatic with increasing age. We detected no cytogenetic variations in nine patients who had studies done and, to date, no tumors have been detected other than a gastric teratoma that was evident in one infant at birth. Longitudinally, the children have not had an unusual incidence of medical problems, and long-term ultrasound monitoring was not burdensome to the families. In comparison, mental and social development to unaffected siblings and cousins appeared normal.

Gastric teratoma: a case report

Gastric teratoma is a very rare, usually benign, tumour of childhood. In industrialized countries, the diagnosis is facilitated by advanced technology when the infant is still in utero or soon after birth, and surgery is performed quite early in life, long before symptoms appear. This tumour was seen in our hospital in a 4-month-old boy. A mass had been noted at birth, but the infant remained symptomless. He was brought to hospital only on account of its rapid growth. The teratoma was successfully excised and the child was not seen again after discharge from hospital. We presume he remains well.

Gastric teratoma with thoracic extension in a 2-year-old boy

A case of gastric teratoma with intrathoracic extension in a 2-year-old boy is reported with a brief review of the literature.

Congenital gastric teratoma in Wiedemann‐Beckwith syndrome

Wiedemann-Beckwith syndrome (WBS) may be associated with abdominal tumors, including Wilms tumor, adrenocortical carcinoma, hepatoblastoma, gonadoblastoma, rhabdomyosarcoma, and neuroblastoma. We report on a newborn infant with WBS and a congenital teratoma of the stomach. This is the sole report of any teratoma being associated with WBS and also the first report of a tumor present at birth and visible prenatally in WBS. At birth this infant boy had the diagnostic findings of WBS with macroglossia, ear lobule creases and pits, nevus flammeus, and omphalocele, and an abdominal mass. Abnormalities were detected prenatally when ultrasound examination showed placental overgrowth, polyhydramnios, omphalocele, and posterior abdominal calcifications. Resection of the mass and partial gastrectomy were performed at age 10 days; histologic study showed an immature grade-II teratoma containing a mixture of mature and immature tissues from all germ layers. Results of cytogenetic studies of blood and teratoma were normal (46,XY). This congenital gastric teratoma in a newborn boy with classical WBS may represent either a tumor or an included twin. We discuss its implications for the association of WBS with neoplasia and monozygotic (MZ) twinning, review various neoplasias associated with WBS, and consider pathogenetic mechanisms.

Malignant Gastric Teratoma in an Infant

Malignancy in gastric teratomas is extremely rare. Such teratomas are widely accepted and treated as benign lesions. A malignant gastric teratoma treated by total excision is presented. According to our knowledge, this is the second case of gastric teratoma having a malignant histology.

Peritoneal Gliomatosis from a Gastric Teratoma

A case of gastric teratoma in a newborn is presented. Ten months after removal of the teratoma, peritoneal gliomatosis was discovered incidentally in inguinal hernia sacs. This is the first report of an association between peritoneal gliomatosis and a teratoma other than ovarian.

Gastric teratoma in children including the third reported female case

Gastric teratoma is a very rare benign tumor. Fifty-three cases, only two of which were females, have previously been reported. This report concerns two cases of teratoma arising from stomach. One of them is the third female case described in the literature.

Teratoma in children under 7 years of age: analysis of 65 cases

This report concerns 65 children under 7 years of age treated during the last 10 years. Sacrococcygeal and ovarian teratomas were most common, but the incidence of retroperitoneal, cervical, and gastric teratomas was far greater than that published in other series (Table 1). Malignancy occurred in 18 cases (26%). Complete excision of benign tumors was curative although there was mortality due to the poor general condition of small patients with large tumors. Survival of the patients with malignant tumors was poor even after postoperative chemotherapy.

Gastric teratoma in an infant

A 40-day-old male infant had massive gastric teratoma. Histologically, it had immature neural elements, among the glial masses. In most of the reported series, the tumor was benign. Malignancy in gastric teratoma is extremely rare.

Gastric teratoma with gastrointestinal bleeding

Gastric teratoma is a rare lesion seen most often in infant males. This case report and review of the literature indicate that an endophytic subtype can be associated with gastrointestinal (GI) bleeding. Neither the age of the patient, the gross appearance of the tumor, nor the presence of intestinal bleeding is evidence of malignancy in this benign condition and simple excision of the lesion is satisfactory treatment.
