Abstract:
The primary localized cutaneous amyloidosis (PLCA) is classified into three types: macular amyloidosis, lichen amyloidosis, and nodular amyloidosis. Macular amyloidosis is characterized by pruritic, hyperpigmented macules and is most commonly located on the interscapular area. Skin lesion usually shows pigmentation with a reticulated or rippled pattern. We report an unusual case of linear macular amyloidosis along the lines of Blaschko. A 74-year-old male is presented with asymptomatic unilateral linear hyperpigmented macules on his right leg for 20 years. Skin biopsy has revealed eosinophilic cytokeratin-positive globular deposits occupying the dermal papillae.
