Systemic form of juvenile xanthogranuloma with involvement of liver and bone marrow is reported in a 2-month-old female infant who presented with hepatosplenomegaly, severe anemia, and thrombocytopenia. There was no skin lesion, nor bone lesion. The enlarged liver has generalized yellowish spots. The diagnosis of juvenile xanthogranuloma was made by pathologic findings of marrow and portal tract infiltration by S-100 negative, CD1a negative, CD68 positive, and Factor XIIIa positive large pale to foamy histiocytes with Touton giant cells, and lack of Langerhans cell granule by electron microscopic examination. The patient was treated with Vinblastine and Etoposide, and experienced slow and gradual disease regression in one year. To the best of knowledge, this is the first documented case of bone marrow involvement in systemic juvenile xanthogranuloma.

Mallory bodies (MBs) are characteristic of several liver disorders, and consist primarily of keratins with transglutaminase-generated keratin crosslinks. We tested the effect of the transglutaminase-2 (TG2) inhibitor KCC009 on MB formation in a mouse model fed 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC). KCC009 decreased DDC-induced liver enlargement without affecting MB formation or extent of liver injury. TG2 protein and activity increased after DDC feeding and localized within and outside hepatocytes. KCC009 inhibited DDC-induced hepatomegaly by affecting hepatocyte cell size rather than proliferation. Hence, TG2 is a potential mediator of injury-induced hepatomegaly via modulation of hepatocyte hypertrophy, and KCC009-mediated TG2 inhibition does not affect mouse MB formation.

Celiac disease (CD) has been associated with several genetic and immune disorders, but association between CD and hereditary fructose intolerance (HFI) is extremely rare. HFI is an autosomal recessive disease caused by catalytic deficiency of aldolase B (fructose-1,6-bisphosphate aldolase). We report the case of a 5-year-old boy suffering from CD, admitted with an initial diagnosis of Reye's-like syndrome. He presented with episodic unconsciousness, seizures, hypoglycemia, hepatomegaly and abnormal liver function. The patient has been on an exclusion diet for three years, but he still had symptoms: stunting, hepatomegaly, high transaminases, but tissue transglutaminase antibodies were negative. Liver biopsy showed hepatic steatosis and mitochondrial damage. The dietary history showed an aversion to fruits, vegetables and sweet-tasting foods. The fructose tolerance test was positive, revealing the diagnostic of hereditary fructose intolerance. Appropriate dietary management and precautions were recommended. The patient has been symptom-free and exhibited normal growth and development until 10 years of age.
