Endometrial stromal sarcoma: a rare entity.

Endometrial Stromal Sarcoma (ESS) is a hormone sensitive tumor. It is a rare gynecological tumor and is considered to occur more often in pre-menopausal women. A proper pre-operative diagnosis is difficult and confirmed in most cases after hysterectomy for a presumed benign disease. Endometrial sampling, ultrasound, and magnetic resonance imaging can provide diagnostic clues. For early disease complete surgical cure is possible, however, adjuvant therapy is available for recurrence. This case of Low Grade Endometrial Stromal Sarcoma (LGESS) in a 21 years old woman was presented as irregular vaginal bleeding. Clinical diagnosis of fibroid was made but analysis of endometrium showed ESS confirmed on hysterectomy specimen. One should consider it in any case with rapid fibroid enlargement.
