Flat topped hypopigmented micropapules on the flank and neck

Lichen nitidus (LN) is a rare inflammatory condition which presents as multiple small, shiny, pale to flesh colored papules measuring 1-2mm in diameter. Lesions typically occur on the abdomen, chest, genitalia and extremities. However, cases of LN involving the nails, oral mucosa and acral skin have been described. Although, it typically presents in children and young adults, there is no gender or racial preference. Clinical and histopathological findings are characteristic for LN and treatment is rarely warranted. Herein we report a case of LN in a 26-year-old African American female who presented with multiple areas of LN.

Human caregivers perceive racial bias in their pet dogs

Is there any empirical support for the popular stereotype that dogs are racist? As an initial inquiry into this question, we investigated whether human caregivers perceive racial bias in the behavior of their pet dogs. In 2 studies, caretakers completed explicit and implicit measures of racial preference and reported their dogs’ behavior toward White and Black people. White caretakers reported that their dogs displayed more positive behaviors toward White than Black people, and these reports of dog behaviors were significantly correlated with caretakers’ own explicit and implicit racial preferences. Increased interracial contact was associated with less reported pro-White dog behavior. Humans perceive racial biases in those around us, including our pets.
