Papillon Lefevre syndrome (PLS) is a rare autosomal recessive disorder, which is characterized by palmar-plantar hyperkeratosis, periodontitis, and premature loss of dentition. We report a 16 years old girl with PLS. The patient presented at 08 years of age with complaints of corn on the feet and hands, and failure to thrive. On examination, her upper primarily canines were loose, she had severe periodontitis, eruption of permanent teeth, diffuse eritematous and hyperkeratotic palms and soles that suggested the syndrome. During the follow-up, the patient was diagnosed to have congenital hepatic fibrosis (CHF) when she was 16 years old, while she was being investigated for the etiology of her splenomegaly and pancytopenia. We report a patient with PLS associated with CHF, an association that has not been previously described.

Cystic fibrosis (CF) is a relatively rare disease in Asians with various clinical characteristics, including CF-associated liver disease (CFLD), which is a common early non-pulmonary complication. This case report describes a Chinese CF patient harboring a homozygous nonsense mutation (c.1657C>T, p.R553X) who was failure to thrive and had intermittently diarrhea during the first year after birth. Liver function test of the patient showed the mildly and intermittently elevated alanine aminotransferase (ALT) levels ranging from 70 to 92 U/L and aspartate aminotransferase (AST) levels ranging from 80 to 90 U/L, which began at 8 months of age and lasted for 4 years without CF diagnosis. In addition, abdominal computed tomography (CT) revealed diffuse fatty infiltration of the liver at 4 years old and gradually developed hepatic cirrhosis. Subsequently, cirrhosis rapidly progressed with obvious splenomegaly and pancreatic insufficiency and the patient died of liver failure with coagulopathy by the age of 6 years old. Pediatricians should remain vigilant to avoid failure to diagnose CF, the occurrence of which may be underestimated, and pay greater attention to the patients with atypical clinical manifestations in Asian countries.
