Gastric teratoma in an infant

Immature gastric teratoma

“…The striking coincidence between the present case and the two previously reported immature gastric teratomas is that immature foci were seen in only the neural component of the tumors (7,8). All of these tumors have been reported in neonates (Table I).…”

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

“…In addition, gastric teratomas have predominantly exhibited benign behavior. Only a few cases of gastric teratomas with malignant components have been reported [10][11][12]. A case of malignant transformation in an adenocarcinoma arising from immature teratoma in an 83-year-old male was reported [14].…”

“…Gastric teratoma patients exhibit characteristic differences in gender (90% are male), age (less than 1 year of age), and malignant behavior compared with patients with teratomas originating in other organs. Malignant gastric teratomas are especially rare, with only a few cases reported [10][11][12]. We describe a case of immature gastric teratoma that recurred as yolk sac tumor (YST) 2 years after the resection.…”

“…2 Even though mouse peritoneal macrophages are used as an in vitro model for studying the pathogenesis of this disease, 3 LD bodies are only rarely observed in body cavity fluids. 1,[4][5][6] The current case was possibly only the fourth reported of an HIV and leishmaniasis coinfection in which the parasite was demonstrated in ascitic fluid. 1,4,5 Visceral malignancies are known to have an immunosuppressive effect, and the ovarian malignancy in this case probably contributed to the HIV infection because of the atypical location of the parasite.…”

“…Only 4 cases of immature gastric teratoma are reported in the literature. [5][6][7][8] Also, a single case of adenocarcinoma arising in an immature teratoma in an elderly male was reported by Matsukama et al. 9 Ultrasonography may be of help in localizing the lesion.…”
