To the Editor.—
The concept of nodular cutaneous mucinosis with lupus erythematosus (LE) has been proposed as a distinct variant of cutaneous LE because of its specific clinical features and the histologic evidence of mucin deposition.1-5 Recently, we examined two patients with systemic LE (SLE) in whom large indurated plaquelike lesions developed that measured 10 to 20 cm in diameter on the trunk. These lesions also had a histologically abundant mucin deposition throughout the dermis. The characteristic large plaquelike skin lesions reported here should be classified as a new clinical variant of cutaneous LE.
Report of Cases.—Case 1.—
A 60-year-old Japanese man with nephrotic syndrome associated with SLE was referred to our department with a large plaquelike skin lesion with a hard cutaneous induration about 10 to 20 cm in diameter on his lower back (Fig 1). The onset of the lesion was unknown and was not preceded by
