This retrospective study of 28 such cases aims to look at its morphological spectrum and to study the correlation of the grade and stage of the tumor with prognosis. Materials and Methods: A retrospective study of 28 cases of IT of the ovary was done. Neuroepithelium was graded as grade I, II and III according to the standard criteria. The presence of immature mesenchyme was also looked for and similarly graded. Results: The median age for the cases was 19 years and abdominal pain was the commonest symptom. Neuroepithelium was seen in 26 cases (6 were grade I, 13 were grade II, and 7 were grade III); and two showed immature mesenchymal tissue (IM) only. IM was seen in all 28 cases, but no correlation with the grade of the IT of the ovary is found. The follow up is available in 23 cases ranging from 6 months to 78 months (median 33 months). Of these, 13 were stage I, 3 were stage II an
