title: Vascular leg ulcers: histopathologic study of 293 patients.
abstract: Vascular leg ulcers remain a challenge for the modern health care, and a systematic pathological study on this kind of lesions has not been reported so far. A total of 293 consecutive white patients with chronic leg ulcers (present for a minimum of 6 months and up to several years) referred to the Wound Care Unit (Dermatology, University of Bologna) between March 2008 and June 2011. Thirty-four patients affected by other than vascular ulcers, neoplastic or inflammatory conditions, were excluded. The remaining 259 patients affected by vascular leg ulcers were enrolled in this study. Assessment of the patients general health, skin biopsy, and vascular Doppler of the lower limbs were performed to determine the etiology and to formulate an appropriate management plan, whereas 2 punch biopsies of 3 mm were performed on the border and on the bed of each ulcer. Doppler evaluation showed the presence of vascular hemodynamic impairment in 259 patients. Of these, 181 (69.9%) patients were affected by venous insufficiency, 58 (22.4%) by venous and arterial insufficiency, and 20 (7.7%) by arterial insufficiency. Histopathologic features revealed significant differences, thus, reflecting the clinicopathologic correlation with the underlying hemodynamic impairments. In conclusion, histopathologic and hemodynamic data correlation could provide the basis for future analysis of leg ulcers pathogenesis and may improve treatment protocols. We should underline that this observational study represents a single-institute experience and that larger series are needed to confirm our observations.
