Case reportĀ 
A 59-year-old woman presented with a one-year history of asymptomatic small papules on the neck. They were slowly increasing in number. The patient had a history of squamous cell carcinoma of the cheek that had been excised. She had not inflammatory dermatosis or trauma on the involved area. There were no similar lesions in her family members. Dermatologic examination showed multiple, 1-4 mm in diameter, flesh-colored, non-follicular, non-confluent and firm papules distributed over the posterolateral sides of the neck (Figure 1).
There were no lesions elsewhere and ophthalmologic examination was normal. Biopsy was performed. Histopathologic analysis showed a normal epidermis and mild thickened collagen bundles in the dermis (Figure 2A). Orcein stains showed a significant loss and fragmentation of elastic fibers in the reticular dermis (Figure 2B). Von Kossa staining was negative. Based on the clinical and histopathological features, the diagnosis of PE was made. We did not prescribe any treatment.
