Abstract:
Objective To study the role of sebaceous gland and its secretion in the progress of abnormal scar and to provide a new idea to prevent pathological scar. Method The sites, pathogenesis and pathological changes were compared between pathological and normal scars.Results Pathological scar often occurred at post-ear, upper lips, maxillofacial skin, and deltoid muscle skin of upper limbs; normal scar often occurred at mid-face, forehead, nose’s tip, and proximal extremity of limbs. Several rows of sebaceous gland and its secretion could be found at the edges of pathological scar, large quantity of sebaceous gland had changes of ductal dilation, and large amount of the secretion accumulated in the cavity in pathological scar; however, on the normal scar base and edges, seldomly showed the expanded sebaceous gland and accumulated secretion. Conclusions Sebaceous gland and its secretion could stimulate the growth of scar. To control the action of sebaceous gland and the formation of secretion could inhibit the formation of pathological scar.
