We report on the treatment of a brother and a sister diagnosed to have basal cell epithelioma (BCE) and the results of HLA. The brother was 79 years old and had a solid type BCE on the left ala of nose, while the sister aged 66 years old had a solid type BCE on the left retroauricular region. HLA indicated All, B54, CW1, DR4, DQ7 as common in these 2 cases. Of these, A11 and B54 are generally observed in Japanese. In this regard, CW1, DR4 or DQ7 was suspected to have a relationship, if any, to the incidence of BCE.
