An imprecisely defined term in dermatological language. It is used for benign connective tissue tumours, reactive connective tissue proliferation (e.g. dermatofibroma), fibroma pendulans; connective tissue hamartomas. In particular, the term " dermatofibroma" is used synonymously with histiocytoma in the European language area. This gives rise to confusion with histiocytosis. Dermatofibroma (histiocytoma) is probably not a real connective tissue tumour, but reactive connective tissue proliferation after focal chronic inflammation (e.g. insect bites). Fibroma pendulans or filiform fibroma is also not a real tumour but rather a skin protrusion (the Anglo-American "skin tag" skin appendage describes exactly this etiology). The group of dermatofibromas has to be completely differentiated from the locally aggressively growing fibromatoses, which behave less like purely benign tumours and more like semi-malignant (locally infiltrating growth; no metastasis) tumours.
