case_images: Among them, the two upper limbs were the weight, and several skin damages were observed together (See Figure 1).

case_images: Head magnetic resonance imaging (MRI) showed multiple blood lesions in the brain (Figure 2).
case_images: Fundus photography showed incomplete peripheral vascularization and foveal hypoplasia (A) Left eye; (B) right eye).

case_images: To further clarify and seek sufficient evidence, the patient was examined by a wide-angle digital retinal imaging system, suggesting that fundus fluorescein angiography showed fundus vascular loop-like changes, consistent with the fundus vascular manifestations of pigmented incontinence (Figure 3).

case_images: In the meantime, the patient underwent skin biopsy, which showed that more eosinophils were aggregated in the epidermis, a small number of dyskeratocytes were scattered in the surrounding epidermis, and a small number of eosinophils and lymphocytes were infiltrated in the superficial dermis (Figure 4).
case_images: Mutational analysis of the IKBKG gene with PCR analysis of blood samples. Lane 1, Marker; Lane 2, IKBKG deletion exon 4-10 control; Lane 3, patient; The IKBKG deletion was detected. Lanes 4 and 5 are the father and mother. Lanes 6, big sister; Lanes 7, healthy control.

case_images: The results suggested that the patient had a heterozygous loss in exons 4-10 of the IKBKG gene, but the parents and older sister were normal (Figure 5).
