We described dermoscopic findings and also how shocking well preserved structures were maintained!
Fig 2 A, Dermatoscopy and histology of the mummy “El niño del Plomo.” Follicular openings and perifollicular pigmentation in skin from the trunk of the mummy (blue arrow). B, Exogenous pigmentation, dermatoglyphs, and acrosyringiums of the plantar region (white arrow). C, Histopathologic examination of plantar skin. The plantar skin sample showed thickening of the stratum corneum and black-brown particulate material of exogenous type in the superficial zone, consistent with dust particles. The melanin pigment status in the specimen was normal. (Hematoxylin-eosin stain; original magnifications: ×4 and ×10.)
