Xanthomas are lipid-rich lesions that signal underlying dyslipidemias. From 2011 to 2022, the Philippine Dermatological Society reported 276 cases, with only 22 occurring in pediatric patients. Familial hypercholesterolemia (FH) is an autosomal dominant disorder with two variants. This case features interdigital xanthomas between the thumb and index finger, which are pathognomonic for the homozygous form and are associated with a higher risk of cardiovascular disease than the heterozygous form.

A 9-year-old girl presented with a two-year history of multiple, asymptomatic, yellowish papules and plaques on her elbows and knees, with no prior trauma or treatment. Interim, new plaques developed in flexural areas, prompting her consultation. Examination revealed yellowish lesions in the webspaces of both hands, knees, elbows, antecubital fossa, and popliteal fossa. Family screening indicated a history of hypercholesterolemia. The lipid profile confirmed hypercholesterolemia, low HDL, and a fourfold elevation of LDL, indicating three times the average risk for cardiovascular disease. Biopsy was consistent with xanthoma. The patient was started on Simvastatin 20 mg daily, along with dietary modifications and exercise recommendations. Family members were also screened. Follow-up tests showed decreased cholesterol and LDL levels, along with reduction in lesion size.

This case underscores the need to recognize xanthomas as indicators of FH. Although many individuals are affected, awareness of the condition is alarmingly low. Xanthomas should not be regarded as mere cosmetic lesions but as warning signs of other underlying conditions that necessitate prompt intervention. Implementing universal screening for children, along with cascade screening for family members is vital.

A xanthoma is a localized collection of tissue histiocytes containing lipid and is usually associated with hyperlipidemia. Tendinous and tuberous xanthomatosis have been found in association with familial hypercholesterolemia, Type III hyperlipidemia, beta-sitosterolemia and cerebrotendinous xanthomatosis. Tendinous and tuberous xanthomatosis without hyperlipidemia have been reported very rarely. Especially tendinous xanthomatosis without hyperlipidemia have not been reported at all in korea. We are reporting a patient with tendinous and tuberous xanthomatosis accompanied by normal plasma lipids

Cerebrotendinous xanthomatosis(CTX) is a rare familial, autosomal disease which seems to be inherited as a Mendelian recessive. It was first described by van Bogaert et al, in 1937 and only about 30 cases have been reported in the literature. CTX is characterized by tendon xanthomas, bilateral juvenile cataracts, progressive dementia and cerebella ataxia. And deposition of cholestanol appears to be the primary lesion in this disease. We experienced a patient, 43-year-old man who sbowed bilateral cataracts, mold cerebellar dysfunction and multiple xanthomas, the tendinous xanthomatosis was confirmed pathologically and the brain CT scan abnormalities were correlated with neuropathologic findings of CTX. We performed extracapsular cataract extraction on both eyes with a significant improvement in corrected vision.

Cerebrotendinous xanthomatosis is a very rare lipid storage disease which is inherited as autosomal recessive trait. The disease is due to an abnormality of cholesterol metabolism, in which excess formation of cholestanol and defect of bile acid synthesis were found. So abnormally high concentration of cholestanol is deposited within the nervous system, the tendons and the other tissues. But, the basic biochemical defect has not as yet been identified. Cerebrotendinous xanthomatosis is characterized by bilateral juvenile cataracts and tendinous xanthomas followed by progressive dementia and cerebellar ataxia. The condition progresses slowly. Death usually occurs during the sixth or seventh decade due to progressive pseudobulbar palsy. The authors have experienced and report a case of presumed cerebrotendinous xanthomatosis in 23-year-old Korean female, and the literatures were reviewed briefly.

Cerebrotendinous xanthomatosis is a rare, inherited lipid-storage disease clinically characterized by tendon xanthoma, progressive neurologic dysfunction(cerebellar ataxia, spinal cord involvement, mental retardation), premature atherosclerosis and cataracts. Substantial elevation of serum cholestanol and urinary bile alcohols with low to normal plasma cholesterol concentrations establishes the diagnosis. Up to now, there have not been any reported case of cerebrotendinous xanthomatosis in Korea. So, we report herein a 36-year-old Korean woman with the clinical features of cerebrotendinous xanthomatosis.

Cerebrotendinous xanthomatosis is a rare autosomal recessive disease that involves multiple organs, including the peripheral nervous system. The present study is the first to report the ultrasonographic findings of peripheral nerves in a patient with cerebrotendinous xanthomatosis. The patient presented with bilateral Achilles tendon enlargement and foot hypesthesia. Sonographic examination revealed hypoechoic, swollen peripheral nerves with enlarged bilateral Achilles tendons. Since the ultrasonographic findings revealed peripheral involvement, the diagnosis of cerebrotendinous xanthomatosis was established after laboratory and genetic studies along with clinical findings.
