Immature gastric teratoma of the lesser curvature in a male infant

Management of fetal teratomas

Fetal teratomas are the most common tumors diagnosed prenatally. The majority of these tumors are benign and cured by complete resection of the mass during the neonatal period. Prenatal diagnosis has improved the perinatal management of these lesions and especially for the teratomas that might benefit from fetal intervention. A comprehensive prenatal evaluation including conventional ultrasounds, Doppler, echocardiography and fetal MRI, is essential for an effective counseling and perinatal management. Antenatal counseling helps the parents to better understand the natural history, fetal intervention, and perinatal management of these tumors, which differ dramatically depending on their size and location. Fetal surgical debulking improves survival in cases of sacrococcygeal teratoma with cardiac decompensation. Additionally, the use of an EXIT procedure reduces the morbidity and mortality if a complicated delivery in cases of cervical and mediastinal teratomas. Here, we offer an overview of all fetal teratomas and their recommended management, with emphasis on in utero treatment options.

Immature extragastric teratoma of infancy: a rare tumour with review of the literature

A full term otherwise healthy, 4-months-old male infant presented with progressive distension of abdomen from 2 months. The clinical examination showed shifting dullness only but no definite lump palpable. The abdominal radiography revealed calcification in right hypochondrium. Serum α-feto protein (AFP), neuron specific enolase, β human chorionic gonadotrophin and urinary vanillymandelic acid (VMA) were appropriate for age-range. Contrast enhanced abdominal CT showed predominantly multicystic lesion in right hypochondrium with central solid component and calcification, but no definite organ of origin determined. The exploratory laparotomy showed extra gastric multilobulated cystic mass sized 23×15×8 cm lesion arising from the lesser curvature of body of stomach. The tumour was feeding through short pedicle based on left gastric artery. There was no infiltration to adjacent areas. Histopathology of excised specimen showed immature teratoma. The child was discharged with appropriate advice and had no recurrence in 1 year of follow-up.

Malignant gastric teratoma: report of two cases from a single center

Gastric teratomas (GT) are rare, accounting for less than 1% of all teratomas. GT usually presents with an abdominal mass, but rarely does it present with gastrointestinal bleeding also. Gastric teratomas are rarely malignant and only two cases are reported in the literature. We treated two cases of malignant GT (endodermal sinus tumor) in infants. Both the patients were male. Surgical excision was done in both the cases. One patient received adjuvant chemotherapy. Both the patients are surviving without recurrence after 5 and 6 years of surgical excision, respectively. Prognosis of GT is excellent even when it is malignant.

Primary gastric teratoma on the cardiac orifice in an adult

Gastric teratoma (GT) is a seldom seen congenital abnormality. GT always occurs in children. The greater curvature and posterior wall of the stomach are the most common sites involving GT. We diagnosed a case of GT located on the inferior wall of the cardiac orifice in a 20-year-old man. To the best of our knowledge, this is the first case of GT located on the wall of the cardiac orifice in an adult in the English literature. We report this unusual case as an addition to this rare disease usually found in children. Computed tomography combined with endoscopic ultrasonography can be selected to diagnose GT.

Recurrent yolk sac tumor following resection of a neonatal immature gastric teratoma

Gastric teratomas are very rare and usually benign. Only a few cases of gastric teratomas with malignant components have been reported. This report describes recurrence of a yolk sac tumor following resection of a neonatal immature gastric teratoma. Gastric teratoma recurring as a malignant lesion has not been previously reported. Recurrence of immature gastric teratomas should be considered, and a periodic follow-up check with alpha-fetoprotein level should be mandatory.

Congenital gastric teratoma with gastric perforation mimicking meconium peritonitis

A case of congenital immature gastric teratoma along with spontaneous gastric perforation in a 1-day-old boy is presented. The clinical features are similar to those of meconium peritonitis. Coincidentally, the child had an arachnoid cyst at 25 months of age. To the best of the authors knowledge, this case of congenital immature gastric teratoma associated with gastric perforation mimicking meconium peritonitis, is the first description in the English-language literature.
