    Abstract:
    BACKGROUND: Papular elastorrhexis is a rare dermatosis characterized by asymptomatic papules on the trunk and the upper extremities. Histological examination shows loss and fragmentation of elastic fibres as well as thickening of collagen bundles. PATIENTS AND METHODS: Case 1: a 46-year-old man was examined with asymptomatic papular lesions for 20 years. Firm and clearly delineated papules ranging from few millimetres to 2cm in diameter became wrinkled at their surface. They were located on the back and symmetrically on the upper limbs. The oldest of them were 15cm wide. Histological examination showed thickened collagen bundles with almost complete loss of dermal elastic fibres, fragmentation of elastic fibres around the lesion and mucin deposits. Standard laboratory tests and bone X-rays were normal. Case 2: a 34-year-old man consulted for clearly delineated asymptomatic papules on the back present for four years. Histological examination was similar to the previous patient and the laboratory tests were normal. He developed Hodgkin's lymphoma. DISCUSSION: We report these two cases because of their particularities as well as the rarity of papular elastorrhexix. The first exhibited large lesions and mucin deposits while the second was associated with Hodgkin's disease. Differential diagnosis of papular elastorrhexis includes Buschke-Ollendorff syndrome, eruptive collagenoma and elastic tissue disorders: macular anetoderma, mid-dermal elastolysis, nevus anelasticus, acne scars and pseudoxanthoma elasticum. The aetiology is unknown. There are no extracutaneous signs.
