Abstract
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.

Summary
(LN) is a rare condition with poorly understood pathophysiology [1,2]. Patients are usually asymptomatic but may have pruritis. Patients with symptoms may warrant a biopsy, especially if seen by generalized practitioners It is most common in children and young adults; it has been described in older patients [3,4]. LN is generally selflimited, clinical presentation and biopsy results may be needed for patient reassurance. Patient reported minor pruritis at times but denied dry, cracked, scaling skin, or any changes to the rash She was evaluated for the rash previously at an outpatient clinic and was prescribed an antifungal cream for tinea. The overlying granular cell layer, and stratum corneum with otherwise fairly unremarkable These morphologic features of multiple small areas of a more mixed histiocytic and lymphocytic infiltrate surrounded by epidermal collarets was diagnostic for lichen nitidus.
