Cytomorphological features of combined myxoid and round cell liposarcoma--a case report.

Fine needle aspiration cytology plays an important role in the preoperative assessment of soft tissue neoplasms. In a 40-year-old man presenting with a large soft tissue mass in the posterior aspect of thigh a diagnosis of myxoid liposarcoma was suggested on FNAC. Scrape smears of the excised mass showed an additional finding of round cell component. Histopathology confirmed combined myxoid and round cell liposarcoma (grade 2), which behaves aggressively when compared to pure myxoid liposarcoma.

Sclerosing stromal tumour of the ovary--a clinicopathologic spectrum.

Majority of the Sclerosing stromal tumours of the ovary documented in the literature are single case reports. We report a series of 4 cases. Among the 4 cases encountered the mean age at presentation was 22.2 years. The clinical presentation varied from asymptomatic mass per abdomen (2 cases), menorrhagia (1 case) and amenorrhoea (1 case). The tumour was unilateral in all the cases with an average size of 10 cms. Grossly the appearances varied from a solid, partly cystic, edematous tumour (2 cases) to solid,firm tumour with yellow flecks (1 case) to unilocular cystic tumour (1 case). Microscopically, the tumour was characterized by cellular pseudolobules composed of a disorderly admixture of collagen-producing fibroblasts and lipid rich lutein cells with shrunken nuclei. In one case the lutein cells had a robust appearance with abundant cytoplasm and vesicular nuclei. The pseudolobules were very vascular and separated by hypocellular dense to oedematous fibrous tissue. Frozen section demonstrated fat in luteinized cells in 3 cases.
