The role of blood vessels in melasma (chloasma) (pregnancy mask)

  • Melasma (chloasma)(pregnancy mask) is characterized by hyperpigmented macules which also tend to appear in hyperestrogenic hormonal states. On histology, there is an increased deposit of melanin in the epidermis.
  • Clinically, melasma lesions are also characterized by redness and telangiectasia. This equates to an increased number of blood vessels when compared to normal perilesional skin.
  • Also, the number of vessels positively correlates with the intensity of pigmentation (role of endothelin)
