“…Benali et al described the first and only case of a mixed germ cell tumor in the soft tissue of the right arm [ 15 ]. Likewise, cases are reported from the neck, stomach, liver, abdomen, and pelvis [ 16 - 18 ]. In our case, clinicians were suspecting an abscess or inflamed benign cyst.…”

Extragonadal teratomas in adults are an extremely rare entity. Teratomas may be mature or immature and are characterized by their midline presentation. We are presenting here a case report of immature teratoma of the palm in a 35-year-old female. The patient developed a recurrent swelling of the palm from which a wedge biopsy was taken and sent for histopathological examination. A diagnosis of “immature teratoma, grade 2” was made, whose margins were compromised. Later on ultrasonography (USG) abdomen and pelvis and whole-body magnetic resonance imaging (MRI) showed no significant findings ruling out the possibility of an occult primary. MRI palm showed a well-defined cystic lesion with loculations suggestive of teratoma. Re-exploration was advised to achieve free margins.

“…An immature gastric teratoma in a newborn is extremely rare and clinically present as abdominal distension with respiratory distress. An immature gastric teratoma in a newborn may be a part of the spectrum of congenital tumors [10][11][12][13][14]. Since the presence of teeth or bone, which is pathognomonic for teratoma, is less frequently present in gastric teratoma, most gastric teratomas are frequently diagnosed preoperatively as a neuroblastoma, Wilms' tumor, mesoblastic nephroma, rhabdomyosarcoma, liposarcoma, or retroperitoneal teratoma [8,[15][16][17].…”

Among the subtypes of germ cell tumors, teratomas are the most frequent in the pediatric population and commonly occur in the sacrococcygeal region and the gonads. Less than 1% of all teratoma are found in abdominal organs including the stomach, liver, and kidney. Gastric teratomas are very rare tumors predominantly found in infants. Moreover, an immature gastric teratoma is exceptionally rare. Here, we present a case of immature gastric teratoma with spontaneous rupture in a newborn who was preoperatively diagnosed with neuroblastoma. On the first day after birth, the neonate presented with progressive abdominal distension accompanying respiratory distress. A firm mass was detected during a physical examination of the abdomen. An emergency exploratory laparotomy revealed hemoperitoneum resulting from a rupture of the tumor located in the posterior wall of the gastric antrum. Complete resection of the tumor and gastroduodenostomy were performed. The pathology evaluation revealed a grade 3 immature gastric teratoma with no malignant components. The patient was treated with adjuvant chemotherapy to prevent recurrence, since the tumor was ruptured in the abdominal cavity and the level of alpha-fetoprotein was decreased but still remained high above the normal range after surgery. In conclusion, physicians should be aware of the existence of gastric teratoma as the differential diagnosis of a huge abdominal mass in infants, especially neonates. Complete surgical removal of the tumor and long-term follow-up has been adopted as the standard management for immature gastric teratoma, although there has been controversy with adjuvant chemotherapy.

“…The presence of immature elements, however, does not have a bearing on the prognosis. Rarely, these tumors may be associated with elevated serum alpha-fetoprotein levels indicative of an associated yolk sac component [16]. However, this may not be demonstrable even after extensive sampling of the tumor.…”
