case_images: A second reading of the biopsy slides was performed at our facility, which confirmed the presence of cells co-expressing CD1a and S100 (Fig. 2a). However, in deeper sections, a burrow containing the edge of a mite was noted in the stratum corneum, suggesting scabies rather than LCH (Fig. 2b).
