\Background Wells' syndrome was first described by Wells in 1971 as a recur
rent granulomatous dermatitis with eosinophilia and was later named eosinop
hilic cellulitis. It is defined by the following criteria: (i) sudden onset
of annular or circinate erythematous-edematous patches that rapidly evolve
to morphea-like blue-slate-colored plaques; (ii) a histological picture us
ually characterized by the presence of 'flame figures'; (iii) non-constant
blood hypereosinophilia.
Methods We describe the case of a 49-year-old woman who reported the sudden
appearance of a few hard, pasty, oval-shaped, reddish-violet, moderately i
tchy, erythematous-edematous patches on both arms about 2 months before our
observation.
Results The remote pathologic history showed that the woman have been submi
tted to quadrantectomy with lymph node dissection followed by cobalt therap
y for breast cancer. Based on the pharmacological history, intake of drugs
was excluded. Routine blood chemistry and instrumental tests did not show a
ny alteration, nor did assays of the main autoantibodies, complement, circu
lating immunocomplexes, or tumor markers.
Conclusions Histologically the picture was compatible with the diagnosis of
Eosinophilic cellulitis. Following topical corticosteroid therapy the lesi
on healed rapidly. It relapsed 2 months later, and was again cured with the
same topical treatment. No further relapses were observed in a 1 year foll
ow-up. (C) 1999 Elsevier Science B.V. All rights reserved.
