[Chronic lupus erythematosus in lupus disease. Retrospective study of 136 patients].
OBJECTIVE
The aim of this retrospective study of 136 patients was to specify the natural history and the systemic prognosis of chronic cutaneous lupus erythematosus. It has been stated that in most of the cases, the disease only affects the skin.


METHODS
From 10 October 1980 to 31 December 1990, 136 patients with the following criteria were included in this retrospective study: clinical signs suggestive of chronic cutaneous lupus erythematosus, characteristic histology, insufficient evidence for the diagnosis of systemic lupus erythematosus.


RESULTS
The prevalence of systemic clinical involvement in the population under study was nearly the same as in the general population. The following biologic or immunologic abnormalities were quite common: leukopenia, lymphopenia, thrombopenia (significantly more frequent among patients having widespread chronic cutaneous lupus erythematosus), low titers of complement levels, positive antinuclear antibodies (usually at a low titer). Eleven out of the 136 patients developed systemic lupus erythematosus, most often over 5 years after the onset of the cutaneous lesions. Four cases out of these 11 had poor prognosis: renal and/or neurologic involvement.


CONCLUSIONS
This data suggests that patients with chronic cutaneous lupus erythematosus could benefit from long-term follow up, since the course to systemic disease occurs in only a few. Usually, antimalarials used singly or in combination with topical steroids may lead to the clearing of the lesions. Thalidomide will occasionally be useful whenever the disease is unresponsive to the preceding measures.
