MASSIVE PAPILLARY DERMAL FATTY INFILTRATION IN A PATIENT WITH PSORIASIS

A 36-year-old Caucasian man presented with chronic, slightly erythemat ous, scaly plaques of 6 years duration. Some improvement was noticed a fter treatment with topical steroids. Differential clinical diagnoses included psoriasis and eczema. A biopsy revealed psoriasiform changes with ''fatty vacuoles'' replacing the papillary dermis. The histogenes is of these findings is unknown. Even though small foci of fatty vacuo lization have been observed in association with heavy inflammatory inf iltrates in skin, this is the first reported case of massive fatty inf iltrates in a non-neoplastic disorder of the skin associated with only sparse inflammatory infiltrate.
