Frequency of facial angiofibromas in Japanese patients with multiple endocrine neoplasia type 1.
The high frequency of cutaneous manifestations in patients with multiple endocrine neoplasia type 1 (MEN 1) has recently been reported. Since prevalence of some cutaneous diseases varies among different ethnic groups, we examined the frequency of facial angiofibromas in Japanese patients with familial MEN 1. Among 27 patients with germline MEN1 gene mutation and one asymptomatic gene carrier, angiofibromas were identified in 43% (12/28) of the subjects. This frequency was significantly lower than that of Caucasian patients, but nonetheless almost equaled those of pituitary tumors and pancreas endocrine tumors. Angiofibromas should be considered as one of major manifestations in MEN 1 regardless of patients' ethnic origin, and clinicians should pay careful attention to the cutaneous lesions in patients with endocrine tumors.
