Clinical Features:

• Erythematous plaques, most commonly on the face or neck
• Male predominance
• Some consider it a form of lupus erythematosus or polymorphous light eruption.
• Unpredictable course with regression and recurrences

Histologic Features:

• Dense superficial and deep perivascular infiltrate of small mature lymphocytes (predominantly T-cells)
• The infiltrate sometimes extends around pilosebaceous units and sometimes into the subcutis.
• Sometimes occasional admixed larger lymphocytes, plasma cells and plasmacytoid monocytes
• A small amount of mucin is often present between the dermal collagen bundles.
• Normal epidermis
• The findings may be quite similar to those of lupus erythematosus, from which it is distinguished by negative immunofluorescence.
