An Unusual Presentation of Facial Porokeratosis Presenting in a Child

We report the case of a 14-year-old African American male who presented with a four-month history of a slowly growing asymptomatic plaque on his face. Physical exam revealed a solitary hyper pigmented plaque that extended from the glabella to the right nasal ala in a linear and confluent manner down the right nasal sidewall. The plaque was lichenified and well demarcated with a distinctive hyperkeratosis ridge like border. Initial biopsy was non-specific. After failing the therapy, a repeated biopsy was done which revealed porokeratosis.
