@drabby6: 1) ragged or red cuticles. Peeling and ragged cuticles can be a subtle sign of an autoimmune disease called dermatomyositis, especially when associated with other rashes on the eyelids, chest and outer thighs. Other autoimmune disease like lupus can be associated with red, inflamed cuticles. 2) long brown or black lines on the nail. While these can be normal, longitundinal melanonychia of the nail can represent melanoma of the nail… especially if changing, irregular, and wider than a pencil eraser ✏️ 3) black splinters under the nails. These are called splinter hemorrhages and can represent something as common as injury to the nail, or can be a sign of vasculitis or a heart valve infection in the right context. If your dermatologist or doctor looks closely at your nails, now you know why. #nail #autoimmunedisease #dermatologist
