12 Possible Causes for Hyperpigmentation, Polymorphic Photodermatitis

  • Acute Hepatic Porphyria

    Secondary infections can cause areas of hypo- or hyperpigmentation or sclerodermatous changes and may result in the development of alopecia at sites of repeated skin damage[] […] manifestations Increased fragility of sun-exposed skin blistering and impaired healing ( blistering photosensitivity ) Healing results in scarring and milia formation Hypertrichosis Hyperpigmentation[] Fragile, poorly healing skin with pruritus, hyperpigmentation and hypertrichosis are other features.[]

  • Acute Intermittent Porphyria

    The affected areas of skin also tend to be fragile and show hyperpigmentation (excess pigment) and hypertrichosis (excess hair).[]

  • Variegate Porphyria

    It is characterized by skin hyperpigmentation and hypertrichosis, abdominal pain, tachycardia, hypertension and neuromuscular disturbances.[] We present the case of two sisters showing cutaneous signs typical of PCT: blisters, photosensitivity, hyperpigmentation, hypertrichosis, cutaneous fragility, and no acute[] Facial hyperpigmentation and hypertrichosis may occur.[]

  • Porphyria Cutanea Tarda

    Other characteristic signs of PCT include dark or reddish urine, general skin fragility, hyperpigmentation, and hypertrichosis.[] Areas of skin that are exposed to the sun can generate blisters, hyperpigmentation, and, sometimes, lesions that heal leaving a scar or keratosis.[] Additionally, hyperpigmentation, hypertrichosis, sclerodermoid plaques, and scarring alopecia might be observed.[]

  • Sunburn

    The long-term effects of sunburn and overexposure to UV rays can include skin discoloration, such as hyperpigmentation, wrinkling and skin cancer.[] When the skin is exposed to high levels of sunlight this may result in hypo or hyperpigmentation which appears as irregular light or dark patches.[] It results in hyperpigmentation and desquamation of the light-exposed areas of the skin.[]

  • Polymorphic Photodermatitis

    THE diagnosis of cutaneous porphyria is suggested by the clinical findings of photosensitivity, hyperpigmentation, hirsutism and increased fragility of the skin.[] polymorphous EnglishSNOMED M-11460 L0032526no S0004714 N Polymorphic photodermatitis EnglishSNOMED Intl D0-75100 L0032526no S0004714 N Polymorphic photodermatitis EnglishSNOMEDCT_US[] […] and other disorders of hyperpigmentation 658 201 Pregnancy dermatoses 662 202 Pretibial myxedema 668 203 Prurigo nodularis 672 204 Prurigo pigmentosa 676 205 Pruritus 678[]

  • Photosensitivity Disorder

    This hyperpigmentation may serve as a protective mechanism against further UV injury.[] : Polymorphic light eruption (PMLE) sufferers develop rashes on the front of the neck, arms, and upper chest, but not the face.[] To endogenous photodermatitis include, in particular, porphyria, xeroderma pigmentosum, eczema, solar, solar scabies, Hydroa vacciniformia (Hydroa vacciniforme), polymorphic[]
