Show Answer
Correct Answer – A
Answer- A-Examine the Lymph node
Tattoo marks are permanent when dye penetrates the dermis.
Infrared photography makes old tattoos readily visible.
A faded tattoo mark becomes visible by the use of ultraviolet lamp 4 or rubbing the part and examining with a magnifying lens.
Marks are recognized even in decomposed bodies (Aret) when the epidermis is removed. Lymph nodes near the tattoo mark show pigment deposition.
