Objective To report one case with congenital ichthyosiform eruption, neurosensory deafness and vascularizing keratitis. Methods The overall clinical and laboratory examinations were conducted to confirm the diagnosis of keratitis, ichthyosis and deafness (KID) syndrome. Results The case presented with the typical hypotrichosis features of the eye lashes and eyebrows, alopecia of the scalp, and ophtalmological lesions. The keratotic plaques over the face, nose, ears, and the extremities were characterstic, and the skin of the trunk was leather-like, dry and hyperkeratotic. Dysplasia of cerebellum, and cystic enlargement of the fourth ventricle of cerebrum, and Dandy Walker syndrome were observed on MRI scanning. Treatment with oral acitretin for 3 weeks cleared the hyperkeratotic ichthyotic lesions on her posterior scalp and also improved other lesions on the extremities and the trunk. Conclusion Acitretin seems to be promising in the treatment of keratotic skin lesions in KID syndrome.

Lipocalin-2 (LCN2) is a secreted glycoprotein originally purified from mouse kidney cells infected with simian virus 40 and plays a key role in the control of cellular homeostasis during inflammation and the response to cellular stress or injury, and it is considered a potential biomarker for rheumatic diseases, cancer, liver diseases, and inflammatory diseases. Studies have shown that LCN2 is expressed in hepatic parenchymal and nonparenchymal cells and is secreted into the bloodstream, and it is closely associated with the development and progression of acute liver injury, liver cirrhosis, viral hepatitis, alcoholic liver disease, nonalcoholic fatty liver disease, and hepatocellular carcinoma. This article summarizes the animal experiments and clinical studies on the association of LCN2 with the pathogenesis of liver diseases, in order to provide new ideas and therapeutic targets for the prevention and treatment of liver diseases.
