[Grover's acantholytic dermatosis (transient acantholytic dermatosis) (author's transl)]

The authors report two cases of Grover's transient acantholytic dermatosis. These two cases exhibit some unusual features. Case no. 1 is that of a 39-year-old female with typical lesions on chest, neck, back and upper limbs. The course was cyclic with spontaneous regressions. This condition had been present for 4 years. Case no. 2 was that of a 46-year-old man with a large erythemato-squamous plaque of the left chest wall exhibiting a vesicular lining. In both instances the histologic findings revealed a picture similar to that of Hailey-Hailey's familial benign pemphigus. In spite of these unusual data, long duration and atypical clinical aspects, these two cases are consistant with the diagnosis of Grover's disease as evidenced by description found in the literature.
