支持皮隆突.

至于专家,名声大的压住名声小的.

不管是从免疫组化结果还是形态学上，都考虑为低度恶性隆皮纤肉瘤。

对于DFSP的起源有学者认为起源于表达CD34的皮肤树突状细胞或者其亚型，或者DFSP可能是某种特殊类型的表达CD34的神经鞘瘤（May be a peculiar type of nerve sheath tumor since CD34 positive, or may derive from a subset of CD34 positive dermal dendritic cells  ）。本例CD34(+++),GFAP(+)，或许更支持这种说法。

而MPNST（恶性外周神经鞘膜瘤）,多发于头颈部及前臂，多数生长于大神经周围体积一般较大可见显著的出血和坏死等，发生于体表皮下者相对少见（至于伴有神经纤维瘤病恶变的病例另论）。本例免疫组化S-100（-）也不支持此诊断。

Bulky deep-seated tumor usually arising from major nerves in neck, forearm, lower leg, buttock。

Gross: large mass producing a fusiform enlargement of a major nerve (often sciatic)Micro: monomorphic serpentine cells, palisading, large gaping vascular spaces, perivascular plump tumor cells, geographic necrosis with tumor palisading at the edges (resembles glioblastoma multiforme)，frequent mitotic figures; may have bizarre cells; 15% have metaplastic cartilage, bone, muscle。

Positive stains: S100 (62%), Leu7/CD57 (in neurofibroma-like areas), p53, CD57 (55%), collagen IV, CD99/O13 (86%), protein gene product 9.5,{but PGP9.5 not specific)
