The diagnosis of LPF-NT rests upon a combination of factors none of which by themselves are definitive. These factors are its clinical presentation, histopathology including the presence of<unk>  cells expressing S100 and CD34 but not SOX10 marker proteins, and<unk>  cell expression of a fusion gene containing part of the NTRK1 gene. LPF-NT has been difficult to distinguish from other oval-shaped/spindle-shaped fibroplast<unk> s that arise in the superficial soft tissue of young individuals such as<unk>  (the presence of a NTRK1 fusion gene indicates the<unk>  is an LPF-NT) and fibroma, infantile fibromatosis, congenital fibrosarcoma, solitary fibrous<unk> , and dermatofibrosarcoma protuberans (broad expression of the CD34 and/or S100 marker protein strongly supports the diagnosis of LPF-NT).
