Clinical and immunologic studies in reticular erythematous mucinosis and Jessner's lymphocytic infiltrate of skin.
BACKGROUND
Little is understood about reticular erythematous mucinosis and Jessner's lymphocytic infiltrate of skin.


OBJECTIVE
Our purpose was to define reticular erythematous mucinosis and Jessner's lymphocytic infiltrate of skin further with focus on immunologic studies.


METHODS
In patients with reticular erythematous mucinosis and Jessner's lymphocytic infiltrate of skin, we measured circulating immune complexes before, during, and after therapy. We examined natural killer cells in a functional assay; we performed direct immunofluorescence and T- and B-cell marker studies in skin biopsy specimens.


RESULTS
The infiltrate in reticular erythematous mucinosis is composed of helper T cells. Circulating immune complexes are increased in both reticular erythematous mucinosis and Jessner's lymphocytic infiltrate of skin and decrease with hydroxychloroquine therapy and clinical clearing. Natural killer cell function is decreased in reticular erythematous mucinosis and Jessner's lymphocytic infiltrate of skin.


CONCLUSIONS
Changes in circulating immune complex titers accompanying therapy with hydroxychloroquine and clinical clearing, with recurrence of the condition and increase in circulating immune complexes on discontinuation of treatment, point to a possible relation between these events.
