Familial lichen planus is rare, and a review of the literature which has appeared since the publication of Spitzer's summary1 in 1924 indicates that conjugal lichen planus is even more unusual. The following cases were encountered in our office practice.
REPORT OF CASES
Case 1.—B. P., a housewife aged 45, was first seen on Aug. 19, 1935. She complained of an itching eruption of eight months' duration, particularly severe on the arms and body. Various local remedies had been used without effecting relief. There had been a gradual spread of the dermatosis. For several years before the onset of the present illness the patient had noticed slowly enlarging white areas in the skin of the abdomen and arms. She stated that her husband complained of pruritic elevated lesions on the legs, which were of two years' duration. Otherwise the history revealed nothing relevant to the present illness.
