[Bowen's disease and squamous cell carcinoma in Haber's syndrome: two cases].
BACKGROUND
Haber's syndrome is a rare form of autosomal dominant genodermatosis. Clinically, it is associated with rosaceiform dermatosis of the face that begins in childhood, and profuse keratotic lesions resembling seborrheic keratoses, seen predominantly on the trunk, the tops of the limbs and the scalp. We report two cases of Bowen's disease and cutaneous epidermoid carcinoma in Haber's syndrome patients.


METHODS
A 67 year-old woman with Haber's syndrome and with a familial history consulted for a budding lesion on the abdomen, histological examination of which confirmed epidermoid carcinoma. A 77 year-old woman presented a clinical picture consistent with Haber's syndrome, with three infiltrated erythematosquamous abdominal lesions. Histological examination of a biopsy sample confirmed the clinical diagnosis of Bowen's disease. The patient was successfully treated with imiquimod.


CONCLUSIONS
These two cases appear to indicate the existence of an association between Haber's syndrome and the presence of cutaneous carcinomatous lesions. We propose the hypothesis of transformation of the keratoses seen in seborrheic keratosis. These lesions may be considered as pre-cancerous. Association with skin carcinomas requires regular monitoring of these patients. The use of imiquimod to treat lesions in patients with Bowen's disease resulted in complete cure.
