Abstract

In a localized form of primary cutaneous amyloidosis, the main clinical types are papular (lichen) amyloidosis and macular amyloidosis. Macular amyloidosis shows a diffuse brownish pigmentation with a characteristic ripple pattern, and papular type also shows hyperpigmentation. It is rarely known that there are disseminated depigmented spots in lesions of macular type1) or amyloid deposits in lesions of vitiligo-like depigmentation2).
