Lipoblastoma--a rare paediatric foot tumour.

Lipoblastoma, a rare benign tumour arising from embryonic fat, is usually found in areas of abundant adipose tissue. Various reports describe a predilection of lipoblastoma for sites with primitive adipose tissue such as axilla, neck, retroperitoneum and prevertebral soft tissue. The plantar aspect of the foot is an extremely rare site due to scarcity of fatty tissue. Differential diagnosis includes lipomas, fibromyxolipomas and liposarcomas. Age of presentation, chromosomal markers and histopathological examination help in arriving at final diagnosis. Radical surgeries are not advocated; however, complete excision is necessary to avoid recurrence.

Malignant glomus tumour--a case report.

Glomus tumours are usually benign neoplasms of glomus bodies. Here we report a rare case of malignant glomus tumour of soft tissue. The tumour was 8 cm in size, infiltrating deep tissue, with nuclear atypia, high mitotic activity (6/HPF), atypical mitosis and showed recurrence, thus fulfilling all the criteria of malignancy.
