다국어 초록 (Multilingual Abstract)

Although spontaneous keloids have been reported, most of hypertrophic or keloidal lesions are developed after certain kinds of traumatic events on predisposing sites. 3 women showing very similar clinical findings presented with erythematous linear hypertrophic scar/keloid-like plaques on medial aspect of their left breast near the areolar area. Itching was noted in 2 women. Trauma histories related with lesion formation were not revealed in all cases. Lesions were developed in their early 40s in 2 patients and late 50s in the other. One patient had a history of ovarian cancer and hypothyroidism, and one patient had asthma and polyneuropathy. No specific abnormal findings were noted in routine laboratory tests. On histologic examination, mild acanthotic epidermal hyperplasia and perivascular lymphohistiocytic inflammatory cell infiltrates were seen in the dermis. Thickened and hyalinized collagen bundles were intermingled with increased numbers of fibrous spindle cells in the dermis of 2 patients. In other patient’s specimen, who has been treated for a long time with intralesional injection of steroid, thickening of collagen bundles were minimal. Although they were thought as hypertrophic scar or keloids at the start, after extensive review of literature, keloidal scleroderma was suspected. We herein report interesting 3 cases of suspected keloidal scleroderma showing unique common clinical features.
