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.
