Hysteroscopic diagnosis of endometrial vascular dystrophy.

tern cover the entire Endometrial vascular dystrophy was first described in 1991 by Jacques E. Hamou [1] as a rare but distinctive hysteroscopic finding. In his original report, Hamou identified 2 variants of vascular dystrophy. The first was characterized by tiny dilated capillaries (spiral vessel–like) that homogeneously covered the entire endometrial surface. In the second variant, meshed or branching capillaries break up into the subepithelial plexus just underneath the basal endometrial layer. Although the pathogenesis of vascular dystrophy is still unclear, the current trend is toward considering it a rare variant of the norm rather than a pathologic entity. Vascular dystrophy has been more often reported in women scheduled to undergo hysteroscopy during the luteal phase of the menstrual cycle and in patients receiving progestogen therapy. The differential diagnosis includes Rendu-OslerWeber disease, in which telangiectasias and arteriovenous malformations of the skin, mucosa, and viscera may be also detected [2]. Herein, we report 2 cases of this uncommon hysteroscopic finding. Case Reports
