An 11-year-old girl presented with a 2-year history of flesh-colored papules on her extremities (Figure 1). The lesions were asymptomatic, of oval or irregular shape and increased gradually both in size and numbers without any treatment. She denied a history of any other inflammatory dermatoses or trauma on the involved area. There was no family history of similar lesions. Dermatological examination showed that multiple flesh-colored, non-follicular papules were discrete and distributed over her lower limbs. The lesions were approximately 5–10 mm
in diameter, of various shapes and slightly hard. No other primary or secondary lesions (erythema or scales, etc.) can be seen around the involved area. Histopathological examination of the skin lesion on the left thigh revealed hyperkeratosis, slight perivascular lymphocytes infiltration and a mild hyperplasia of collagen fiber in the dermis. Elastic tissue staining (Resorcinol-Fuchsin stain) showed a significant reduction, fragmentation or complete loss of elastic tissue in upper and mid dermis (Figure 2). Based on the clinical and histopathological features, a diagnosis of papular elastorrhexis was made. No treatment was performed because of the benign process of this disease and asymptomatic character of the lesions. She was followed up for one year and showed no improvement in the involved lesions.
Papular elastorrhexis (PE) is a rare acquired elastic tissue disorder which was first described by Bordas et al. [1] in 1987. The etiology of this disease is still unclear. Papular elastorrhexis usually occurs in children or adolescents with a predilection for women. Its clinical characteristics are multiple asymptomatic, non-follicular flesh-colored papules, between 3 and 5 mm in size. Papules are firm and mainly distributed over the trunk or upper extremities with no fusion. In addition, there is no osteopoikilosis or similar family history and usually occurs without any previous history of acne, inflammation or trauma. The prominent histopathological feature of PE is the reduction, fragmentation or complete loss of dermal elastic fibers. Collagen fibers can be normal, focally thickened or even homogenized with a few lymphocytes infiltrated around the blood vessels [2].
Papular elastorrhexis has not received a well-recognized division and it is still controversial whether PE is a distinct entity or a variant of nevus anelasticus (NA) or abortive form of Buschke-Ollendorff...
