The findings in this study suggest that SP and CGRP are expressed in the glands of the EAC skin and secreted in the process of ceruminous gland secretion. Case #1. It was then reflected anteriorly and sutured in place medially to reinforce the EAC closure . Meatoplasty with canalplasty and tympanoplasty in individuals with CAS can yield reliable and lasting positive hearing results with a low incidence of severe complications. Erythema annulare centrifugum (EAC) is an annular, erythematous lesion that appears as urticarial-like papules and enlarges. The thicker skin over the outer (cartilaginous) portion of the EAC contains apopilosebaceous units comprising apocrine and eccrine glands that secrete their products around the base of a hair follicle.
