Background:
Multiple eruptive dermatofibromas (MEDF) are rare and their etiology is unknown. An association with immunosuppression has led to the speculation that they are the result of an abortive immunoreactive process. In the literature, there have been 5 isolated case reports of multiple dermatofibromas and human immunodeficiency virus (HIV) infection. Three of these cases had other immune modulators present (i.e. prednisone, systemic lupus erythematosus, alpha-interferon, UVB phototherapy). The other 2 cases had disseminated mycobacteriosis.
Observations:
A series of 3 men with HIV infection and MEDF is described. In contrast to previous case reports, our patients did not have other immune modulators besides HIV infection nor did they have disseminated mycobacteriosis.
Conclusions:
This series lends support to the speculation that MEDF may be associated with immunosuppression. Further study is needed to delineate the exact mechanism for this relationship. These patients presented within a 4-month period and illustrate the frequency at which MEDF may be seen in the HIV-positive population. As clinicians who care for patients with HIV infection, it is important to be aware that MEDF may be seen in this immunosuppressed population.
