Pfeifer-Weber-Christian Disease and Benign Multiple Subcutaneous Noninfiltrative Angiolipomas: A Puzzling Case and Review of a Rare Entitety
Abstract Background: Pfeifer-Weber-Christian disease (PWCD) is one of many rare diseases that may be easily missed if there is not a high degree of suspicion. Angiolipomas are rare, benign subcutaneous tumors, composed of adipose tissue and blood vessels and often containing fibrin thrombi. The majority of angiolipomas occur sporadically; however, there is a minority of cases that have been associated with long-term corticosteroid use. Case presentation: We report here an unusual case of PWCD associated with benign multiple subcutaneous noninfiltrative angiolipomas confirmed by skin biopsy. Systemic corticosteroid therapy was not effective at reducing flares of panniculitis, and during this therapy angiolipomas gradually increased in size. In contrast, administration of oral Cyclosporine A (CyA) led to a rapid remission of the PWCD. Conclusions: As PWCD has no known aetiology and no specific treatment has been established, the successful therapy with the CyA supports the hypothesis that PWCD is a T cell mediated autoinflammatory condition. Also, this case represent very rare side effects of corticosteroid therapy, such as induction of de novo angiolipomas or increased growth of existing tumours. This case bring diagnostic difficulties in everyday clinical practice, especially in patients with panniculitides, but histopathological evaluation usually resolves the dilemma.
