所提供的图片里，见到真皮浅层以下大量结节状增生的成熟脂肪细胞，结合临床描述，个人认为浅表脂肪瘤样痣可以考虑，但是临床上有的挤压出乳白色分泌物有点不好解释。但是，大的浅表脂肪瘤样痣可以出现肿物表面水疱（水疱型浅表脂肪瘤样痣），可以分泌粘液样物，这里描述的大者如鸡蛋，不知可否提供临床图片。
真皮网状层可见一表皮样囊肿结构，也许是合并的吧？
毛囊皮脂腺囊性错构瘤多见于面中部，为孤立性，也有见于外生殖器的报道，由毛囊、皮脂腺、纤维间质为主构成，质地不应该是柔软的。可见很多皮脂腺小叶通过皮脂腺导管与漏斗部囊腔相连，这里很少见，个人觉得不考虑毛囊皮脂腺囊性错构瘤。

Nevus lipomatosus superficialis (NLS) is an uncommon hamartomatous lesion of the skin characterized by the presence of clusters of mature fat cells among the collagen bundles of the dermis. Usually, the number of adnexal structures is reduced in NLS as compared to the normal adjacent skin, but their morphology is not altered. Nevertheless, in some instances, associated pilar abnormalities have been reported. We here report 2 cases of NLS with disorganized pilosebaceous units. The follicular structures were dilated and showed infundibular type keratinization and there were numerous mature sebaceous lobules radiating from them resembling the histology of a folliculosebaceous cystic hamartoma (FSCH) or a sebaceous trichofolliculoma. Only 2 cases of NLS with FSCH have been previously reported. Our cases represent examples of a very rare hamartomatous cutaneous lesion composed of mesenchymal and epithelial components.
