A 60-year-old Chinese man presented to our department in 2010 with a 3-year history of a thick, asymptomatic, dark brown pigmented keloid. The patient had a history of chest and abdominal keloid after being burned by hot water 20 years ago. Ten years ago, he had a keloidectomy and x-ray radiotherapy at a local hospital. Most of the skin lesions were cleared after treatment. However, three years later, a new keloid arose by the edge of the remnant skin lesions and expanded gradually. Two years ago, a few dark brown dirty crusts began to occur on the scars, progressively accumulated, and coalesced to form large and thick sheets on the surface of the skin lesions. Soon after these sheets were forcefully peeled, the same crusts would grow again.His general physical examination was unremarkable. Skin examination revealed large areas of irregular atrophic scars on the chest and abdomen, and on the edge of these scars were prominent cord-like dark red patchy tumors covered with patchy dark brown, dirt-like adherent crust. In addition, the thick dark brown crusts covered most of the atrophic scar (Fig. 1a).Direct smears and cultures of crusts for fungus and bacteria were negative, and other laboratory findings were within normal limits. Figure 1 (a) Skin examination of the chest and abdomen. On the chest and abdomen there were large areas of irregular atrophic scars, and on the edge of these scars were prominent cord-like dark red patchy tumors covered with patchy dark brown dirt-like adherent crust. (b) Skin biopsy revealed excessive epidermal hyperkeratosis and the stratum spinosum was significantly thinner. Some of the epidermal foot extended downward and intertwined within which there were pseudokeratinous cysts. Collagen fibers in the superficial reticular layer of the dermis were significantly proliferative and swollen, and between the collagen fiber bundles there were abundant mucous matrices (hematoxylin and eosin, 9100) ª (a) (b)

Cutaneous dirt‐adherent disease (CDAD) is a rare psychogenic dermatosis mainly occurring in young Japanese and Chinese women. It mainly occurs on cheeks, forehead, nipple, mammary areola and around mammary areola. To our knowledge, this is the first case of CDAD with the skin lesion of psoriasis rupioides to be reported. In our case, the patient, a 43‐year‐old Chinese man presented with thick, yellowish‐brown adherent crusts on his face with severe painful 6‐days duration. Histopathologic image: Parakeratosis, the epidermis demonstrates regular acanthosis with some thinning of the suprapapillary plates, neutrophils exocytosis are noted. As for the histopathologic diagnosis in his right crus, combined with the clinical manifestation of rupioides‐shaped crusts, film phenomenon and Auspitz's sign, we considered Psoriasis rupioide.
