Papulonodular mucinosis associated with subacute cutaneous lupus erythematosus.

Mucin deposition is a common histopathologic finding in lupus erythematosus (LE) but is rarely present in sufficient quantity to produce clinically apparent skin lesions. Until now, fewer than 40 cases of papulonodular mucinosis associated with LE have been reported in the literature, and it was associated with either systemic LE or discoid LE. For the first time, to our knowledge, we describe 2 patients with subacute cutaneous LE who presented with papulonodular mucinosis as a major clinical manifestation of their disease.
