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[mayomedicallaboratories.com] […] manifestations Increased fragility of sun-exposed skin blistering and impaired healing ( blistering photosensitivity ) Healing results in scarring and milia formation Hypertrichosis Hyperpigmentation[amboss.com] Fragile, poorly healing skin with pruritus, hyperpigmentation and hypertrichosis are other features.[patient.info]

  • Acute Intermittent Porphyria

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

  • Variegate Porphyria

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

  • Porphyria Cutanea Tarda

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

  • Sunburn

    The long-term effects of sunburn and overexposure to UV rays can include skin discoloration, such as hyperpigmentation, wrinkling and skin cancer.[besthealthmag.ca] 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.[dermalinstitute.com] It results in hyperpigmentation and desquamation of the light-exposed areas of the skin.[fpnotebook.com]

  • Polymorphic Photodermatitis

    THE diagnosis of cutaneous porphyria is suggested by the clinical findings of photosensitivity, hyperpigmentation, hirsutism and increased fragility of the skin.[nejm.org] polymorphous EnglishSNOMED M-11460 L0032526no S0004714 N Polymorphic photodermatitis EnglishSNOMED Intl D0-75100 L0032526no S0004714 N Polymorphic photodermatitis EnglishSNOMEDCT_US[doctor.am] […] 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[books.google.ro]
