Description: Histology of shave with basal layer hyperpigmentation

History:

 This lady had a slowly growing pigmented lesion on her cheek . The clour was varying a bit. The dermatoscopy did not show grey circles or other features of early lentigo maligna. Her shave biopsy showed only increased melanin in basal keratinocytes. This was a lentigene. It was lasered off for cosmetic reasons.
