Sternal erythema: a distinctive postsurgical eruption.

Abstract

Wound complications constitute a diverse array of surgical and dermatologic entities. We sought to describe the clinical and pathologic attributes of a series of patients in whom a distinctive thoracic surgical wound eruption developed after coronary bypass grafting. We performed a detailed chart review, including history, surgical procedure notes, and biopsy findings, obtained from 3 patients; we examined the data and reconciled them with conventional etiologies in an attempt to discern a shared diagnosis and pathogenesis. The patients were white men (59, 68, and 73 years of age) in whom roughly symmetrical asymptomatic erythema developed within the borders of their sternal thoracotomy wounds between 1 and 2 years after open heart surgery. The cutaneous findings consisted of macular erythema and poikiloderma that blanched with external pressure. Biopsy findings yielded epithelial atrophy with capillary telangiectases. Although cellulitis, dermal hypersensitivity to surgically implanted hardware including sternal wire, and an anatomic variant of costal fringe remain as possible diagnoses, an additional consideration includes a form of postsurgical reflex sympathetic dystrophy.
