Abstract
- Tumid lupus erythematosus is a rare subtype of chronic cutaneous lupus erythematosus. We report a case of tumid lupus erythematosus. A 51-year-old female patient, presented with a solitary walnut sized tender erythematous nodule on the left forehead. Histopathologic findings showed dense perivascular and periadnexal lymphocytic infiltration, mucin deposition between the dermal collagen fibers like cutaneous lupus erythematosus. But there was no involvement of epidermis or dermoepidermal junction. Those histopathologic findings suggest polymorphous light eruption, Jessner lymphocytic infiltration and reticulated erythematous mucinosis. Mucin deposition is seen in reticulated erythematous mucinosis and tumid lupus erythematosus. To distinguish tumid lupus erythematosus from reticulated erythematous mucinosis, clinicopathologic correlation is essential.
