Sir,

A 58-year-old Japanese male visited the Department of Dermatology of Fukushima Medical University Hospital, complaining of itchy eruptions on his trunk and lower legs. The skin rash had previously been treated with topical antihistamine cream, but without improvement. He had a past history of diabetic nephropathy and has been received peritoneal dialysis for 9 months. The patient’s family history was noncontributory. Physical examination revealed a number of papulonodular eruptions on the trunk and hyperpigmented, keratotic, and firm papules and nodules on the lower parts of thighs and upper parts of shins (Fig. 1a and 1b). Skin biopsy taken from the left leg showed epidermal hyperkeratosis and deposition of amorphous eosinophilic substance in the papillary dermis, which was evident on Congo-red and ant-cytokeratin antibody 34βE12 staining (Fig. 2ac). Immunohistochemical staining of the β2-microglobulin was negative. The clinical and histological findings confirmed lichen amyloidosis. We conducted half-side test by topical corticosteroid and moisturizing agent, in which the former was more effective. He achieved mild remission of symptoms in a period of one month.

Patients with chronic renal failure commonly exhibit cutaneous manifestations, such as pruritus, dry skin, hyperpigmentation, acquired perforating dermatosis, nephrogenic systemic fibrosis, calciphylaxis, porphyria cutanea tarda, and pseudoporphyria [1]. Furthermore, if dialysis is introduced, dialysis-related amyloidosis sometimes occurs during long-term course. In dialysis-related amyloidosis, skin manifestations often present with cutaneous or subcutaneous nodules [2]. Bilateral subcutaneous masses are seen on the buttocks, which are sometimes painful on sitting. Extensive deposition of β2-microglobulin amyloid is seen in the dermis to subcutis, occasionally associated with local calcification. Beta2-microglobulin, which is not readily removed by hemodialysis deposits as amyloidosis. A previous report suggested that massive dermal and subcutaneous amyloid nodules on the buttocks of a patient on hemodialysis [3]. By contrast, in our case, we could not find nodular lesions on the buttocks.

Lichen amyloidosis frequently occurs on the extensor surfaces of the lower legs, and on the forearms and back. Lichen amyloidosis has been reported in associated with several skin disorders such as atopic dermatitis, lichen planus, C-type hepatitis, and mycosis fungoides [4,5]. However, lichen amyloidosis associated with chronic renal failure has not been reported, and to our knowledge, this is the first case of lichen amyloidosis in a patient with chronic renal failure.

The underlying cause of amyloid deposition is unknown. In our case, systemic amyloidosis was excluded by detail investigation. Several immunohistochemical studies have demonstrated reactivity between anti-keratin antibody and cutaneous amyloid deposits in lichen amyloidosis. Amyloid deposits may be derived from degenerated epithelial keratinocytes [6], possibly through filamentous degeneration or apoptosis [7]. In the present case, amyloid materials were also stained positive for 34βE12, suggesting that the origin of amyloid is degenerating epidermal keratinocytes which may represent precursors of cutaneous amyloid. The patient complained of itching on the trunk and extremities, and he noticed frequent scratching. Thus, amyloid deposition on the lower legs may be induced by epidermal minor trauma induced by repetitive scratching.
