- 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
- 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.
