Verruciform xanthoma are clinically isolated lesions with a low incidence rate of concomitant hyperlipidaemia, but has been described to be associated with other conditions incuding congenital hemidysplasia with ichthyosiform erythroderma and limb defects (CHILD), recessive dystrophic epidermolysis bullosa, keratitis-ichthyosis-deafness syndrome, epidermal naevus syndrome or human immunodeficiency virus infection. We found only three cases with concomitant skin diseases without an inheritance syndrome. One of these patients was a 44-year-old healthy man with a lesion occurring in an epidermal cyst. There are a few published reports of crateriform verruciform xanthoma or cystic verruciform xanthoma. 8,9 A second patient, a 35-year-old healthy man, had an erythematous papule on the scrotum since childhood. He also complained of fissures on the either side of the scrotum. Histopathology showed marked acanthosis with extensive acantholysis, neutrophilic exocytosis, foamy histiocytes in the papillary dermis and mononuclear cell and neutrophils in the dermis, which is compatible with Hailey-Hailey disease. The third patient, an 82-year-old male had a condyloma accuminatum, though the HPV DNA test was not performed. This study's limitation is that all the cases were from a tertiary hospital and lacked a direct molecular-biologybased analysis. However, elderly Taiwanese men appear to have a higher risk of genital predominance of verruciform xanthoma, and the role of androgen and androgen receptor may be crucial.
