Keywords: Histopathology-image
In necrotising infundibular crystalline folliculitis, sections show filamentous deposits, enclosed by parakeratotic columns within partly necrotic follicle ostium (figure 1). There is incidental actinic keratosis in the case illustrated herein. Higher power examination shows crystalline urate-like structures within the filamentous material (figures 2, 3). The material is birefringent with polarised light.
