Abstract

Summary: Multiple dermatofibromas (DFs) are rare benign fibrohistiocytic lesions characterized by asymptomatic hyperpigmented nodules. Several diseases, like systemic lupus erythematosus (SLE) and human immunodeficiency virus (HIV) infection, are found to be associated with multiple DFs. Here, we designed a systematic review by an electronic search of PubMed and Embase databases to select case reports of multiple DFs (29 May 2021). From 2, 145 initially found articles, 96 studies (106 cases) were included. We classified multiple DFs (>1 DF lesion) into four subtypes and separately investigated clinical characteristics of each one: multiple eruptive DFs (MEDFs) (n = 45), multiple (n = 41), multiple clustered DFs (MCDFs) (n = 18), and giant combined (n = 2). The patients' mean age was 38.3 ± 14.7 years. The majority were female (61.3 %). The lesions were commonly on the trunk and extremities (36.8 %). MEDFs (n = 36) had the most rapid disease onset (2.0 ± 6.6 years). Immunosuppression induced by either HIV (10.3 %) and hematologic malignancy (9.4 %) or immunosuppressive drugs (23.4 %) along with SLE (19.8 %) were the most observed associations. However, 66.7 % of the MCDF patients were otherwise healthy individuals. As for disease management, surgery and follow‐up were the preferred options. Most of the cases showed neither resolution nor development of new lesions in follow‐up.
