Acquired perforating dermatosis is a group of disorders with transepidermal elimination of collagen, elastic tissue, or necrotic connective tissue seen in one-tenth of hemodialysis patients.[1]

A 57-year-old patient with end stage kidney disease due to diabetes had been on twice weekly hemodialysis through left radiocephalic arteriovenous fistula for 1½ years. He gave history of recurrent episodes of intensely pruritic rashes all over the body during last 1-year.

On examination, he showed multiple discrete hyperpigmented lesions over the trunk, both arms and thighs [Figure 1]a with few lesions having central keratotic papules [arrowhead in [Figure 1]b. Some lesions were inflamed suggestive of secondary infection. There were multiple itch marks and linear pattern of skin lesions over the right thigh suggestive of Koebner's phenomenon. A diagnosis of acquired perforating dermatosis was made, and the patient was started on oral antibiotics, antihistamines, topical steroid, and emollients. The skin lesions healed with scarring. Three months later, the patient again had a fresh bout of similar lesions. The patient was started again on topical steroids and antihistamines. The patient was lost to follow-up.

Skin manifestations in chronic kidney disease can be nonspecific or specific to the kidney disease. Nonspecific manifestations are pruritus, ichthyosis, xerosis, pigmentary changes, and half-and-half nails. Specific manifestations include uremic frost, acquired perforating dermatosis, blistering disorders, calciphylaxis, metastatic calcification, and nephrogenic systemic fibrosis.[2]

Acquired perforating dermatosis is usually associated with diabetes mellitus and chronic kidney disease often after initiation of dialysis. However, it has been also reported in transplant recipients, nondiabetic hemodialysis patients, and chronic kidney disease patients not yet on dialysis.[3] Acquired perforating disorders are divided into four diseases according to the type of epidermal disruption and the nature of the eliminated material: Kyrle's disease, perforating folliculitis, elastosis perforans serpiginosa, and reactive perforating collagenosis.[4]

The exact pathophysiology is unknown. Localized skin irritation, typically from scratching, may cause an inflammatory cutaneous reaction to uremic substrates in the dermis, leading to lesion formation.[5]

Patients present with moderate to severe pruritus in the affected skin areas and characteristically have pruritic, firm, dome-shaped papules or nodules with a central keratotic plug distributed on the extensor surfaces of the extremities and trunk. Individual lesions are crateriform, umbilicated, or centrally hyperkeratotic papules and nodules. Palms and soles were mostly spared.[2] Koebnerization (formation of lesions in areas of skin trauma, most notably from scratching) is common. Lesions may develop in crops and resolve after 6–8 weeks with scarring.

The diagnosis of is made on clinicalgrounds and confirmed with a lesional skin biopsy.[2] Histologically, these disorders are characterized by the transepidermal elimination of dermal substrates, such as collagen, keratin, and elastic fibers.[6] Differential diagnosis includes verruca vulgaris, eruptive keratoacanthoma, hypertrophic lichen planus, follicular keratosis, phrynoderma, prurigo nodularis, benign nodular calcification (calcinosis cutis), and calciphylaxis.[7]

APD can be differentiated from calciphylaxis by the presence of intensely pruritic papules or nodules most commonly in lower limbs in the former whereas calciphylaxis starts as violaceous mottling that progress to severely painful plaques or nodules and subsequently become necrotic ulcers covered by eschars often in the lower extremities, abdomen and buttocks, both of which have large amounts of subcutaneous fat.[2] Histologically, calciphylaxis is characterized by medial calcification and thrombosis of blood vessels in the dermis and subcutaneous tissue and APD by the transepidermal elimination of dermal structures.[2]

Treatment is often frustrating as lesions can persist, and chronic scars can develop.[8] The most commonly reported treatments were topical and intralesional steroids, oral antihistamines, and topical retinoids. Others include narrow band ultraviolet B, psoralen plus ultraviolet A, oral retinoid, and cryotherapy.

As chronic kidney disease patients are living longer, the incidence of these cutaneous diseases will likely increase, thereby affecting the quality of life. Therefore, physicians need to have a high index of suspicion in patients with diabetes along with concomitant chronic kidney disease.
