BACKGROUND: We have identified nine cases of a variant of superficial lipoma that are characterized by the presence of eccrine sweat glands. OBJECTIVE: The purpose of this study was to elucidate the clinical and histopathologic features of this distinctive lesion. METHODS: Nine cases of lipoma that contain eccrine glands were retrieved from our pathology files from 1989 through 1992. Their clinical and histopathologic features were studied and compared with those of conventional lipoma. RESULTS: The clinical features of these lesions did not deviate appreciably from those of the usual lipomas. However, their microscopic appearances differed by the presence of displaced and distorted eccrine glands. One lesion had the added features of a myxolipoma. CONCLUSION: Adenolipoma of the skin is a distinct lesion that can occur in the dermis or subcutaneous tissue.
