Cutaneous findings in Fanconi anemia

Area of Science:

• Genetics
• Dermatology
• Hematology

Background:

• Fanconi anemia (FA) is a rare genetic disorder causing bone marrow failure and physical abnormalities.
• Delayed diagnosis of FA is common due to poorly defined early disease characteristics.

Purpose of the Study:

• To document the range of skin manifestations in patients diagnosed with Fanconi anemia.

Main Methods:

• A cross-sectional study involving full-body skin examinations of FA patients.
• Statistical analysis using Poisson and logistic regression to correlate pigmentary changes with patient characteristics.

Main Results:

• Nearly all (96.8%) FA patients exhibited at least one cutaneous pigmentary alteration, frequently before age 13.
• Common findings included café-au-lait macules, hypopigmented macules, and freckle-like macules in skin folds.
• A significant observation was the co-occurrence of both hypopigmented and hyperpigmented macules.

Conclusions:

• Distinctive FA skin findings include faint café-au-lait macules, hypopigmented freckle-like macules in skin folds, and mixed pigmentary macules.
• Early identification of these dermatological signs can facilitate earlier diagnosis of Fanconi anemia.
