Abstract
A 49-year-old men noted depigmented macules on the back of his hand around December 1993 which thereafter gradually spread to the head and trunk without any other symptoms. The diagnosis was vitiligo vulgaris (type A) non-dermatomal distribution. The administration of weak topical steroids was used during the follow-up period. Thereafter, an infiltrative, keratotic, and atrophic lesion occurred on his abdomen in July 1994. The lesion measuring 52mm×31mm, with well-defined margins and a lilac ring around it. Histopathologically, hyperplasia and the proliferation of collagen fibers were noted in all layers of the dermis and cellular infiltration, predominantly by lymphocytes, was also observed around the blood vessels and appendages, thus resulting in a diagnosis of morphea. The combination of vitiligo vulgaris and localized scleroderma is rare and immune disorders are said to be involved in the occurrence of both diseases, although the mechanism remains to be elucidated. However, a previous study of complicated cases revealed that type A vitiligo vulgaris to be associated with localized scleroderma in most cases.
