[Pyoderma gangrenosum and systemic lupus erythematosus: A rare association]
Introduction:
Pyoderma gangrenosum (PG) is a neutrophilic dermatosis that is traditionally associated with systemic disorders such as chronic inflammatory bowel diseases, rheumatoid arthritis and malignant hematologic disorders. Its association with systemic lupus erythematosus (SLE) is rare and not well known. We report a case of this association with a review of the literature.
Case Report:
A 43-year-old female patient, followed for 4 years for SLE, presented a deep ulceration of the anterior face of the left thigh with inflammatory borders, an ulcerated nodule of the right shoulder and four small ulcerations of the back of the right hand. The biopsy of the ulceration of the left thigh concluded to PG. The patient was treated by corticosteroids with complete healing of lesions.
Conclusion:
The prognosis of lupus does not seem to be aggravated by PG and the treatments of a SLE flare are usually enough for treating associated PG.

One of the core constructs in social psychology is the notion of an attitude toward an object or person. Traditionally, psychologists measured attitudes by simply asking people to self-report their beliefs, opinions, or feelings. This approach has limitations, however, when measuring socially sensitive attitudes, like racial prejudice, because people are often motivated to self-report unprejudiced, egalitarian beliefs (despite...
