Khái niệm cốt lõi
Hereditary hemochromatosis patients often present with a wide range of skin manifestations, including hyperpigmentation, hypertrichosis, alopecia, and other dermatological changes.
Tóm tắt
This systematic review examined the dermatological symptoms associated with hereditary hemochromatosis (HH), a genetic disorder characterized by increased iron absorption and accumulation in the skin, nails, and mucosae. The review analyzed 22 studies from various countries, involving 148 patients with hereditary or idiopathic hemochromatosis.
The key findings include:
- Hyperpigmentation, including scars, grayish skin pigmentation, and tanned skin, was the most common dermatological manifestation, reported in 97.22% of patients.
- Hypertrichosis of the face, frequently associated with porphyria cutanea tarda, was reported in 75% of patients.
- Alopecia, in various forms, was reported in 75.7% of patients.
- Other dermatological manifestations included nail changes, ichthyosis-like skin changes, skin atrophy, and mucosal pigmentation.
- Vitiligo, pruritus, and palmar erythema were also reported, though less frequently.
The authors emphasize the importance of a systematic approach by physicians in recognizing dermatological presentations of HH, as skin manifestations were the primary or only complaint in many cases. They recommend considering HH in patients with unexplained pruritus, alopecia areata, excessive skin pigmentation, or unusual pigmentation in structures not previously pigmented.
