Introduction: Reticulated hyperpigmentation is a relatively uncommon dermatologic pattern. It is used to describe brown-colored skin lesions that manifest in a lacy or net-like distribution. When a clinician encounters a patient with reticulated hyperpigmentation, its location is often the most helpful feature in establishing a differential diagnosis. As this pattern is rarely observed on the scalp, this site is currently not included in the diagnostic approach. Case Presentation: In this report, we present a case of lichen planopilaris (LPP) in a black man who presented with reticulated hyperpigmentation over the scalp. Conclusion: We suggest that it may be warranted to add LPP to the differential diagnosis of reticulated hyperpigmentation, especially when arising on the scalp of darker skinned individuals.
