Ganglioneuroblastoma is an uncommon peripheral neuroblastic tumor. They have intermediate malignant potential, in between that of neuroblastomas and ganglioneuromas. Histologically, they are considered to have intermediate malignant potential because they contain primitive neuroblasts along with mature ganglion cells. In literature, reports of this entity being diagnosed by fine needle aspiration and its cytological appearance are scarce.

Solid-pseudopapillary tumors are unusual pancreatic neoplasms of low malignant potential that most frequently affect young women. They are histologically, clinically, and prognostically quite distinct from the more common pancreatic ductal adenocarcinomas. Despite their often large size the vast majority of solid-pseudopapillary tumors are indolent neoplasms. They are confined to the pancreas in 85% of patients, and even the 10 to 15% of patients with liver or peritoneal metastases commonly enjoy long-term survival.

BACKGROUND: Immature teratoma is the currently preferred term for the malignant ovarian teratoma composed of a mixture of embryonal and adult tissues derived from all three germ layers, regardless of its gross appearance. AIM: to distinct mature and immature teratoma when dealing with ovarian germ cell tumors. CASE SUMMARY: a 30 year female presented with intra abdominal mass and ascitis. Grossly, variable size nodule and cystic areas are seen. Microscopically, carcinoid like lesion, thyroid tissue immature neural tissue and glandular tissue noted. Diagnosis of immature teratoma grade 3 was made. DISCUSSION: immature teratoma of ovary accounts for 10-20% of all ovarian tumors and is considered second most common germ cell tumor following mature teratoma. It is usually seen in children and adolescents. CONCLUSION: A thorough search for immature elements in a teratoma is necessary for proper grading, management and assessing prognosis of cases with immature teratoma.
