Nevus lipomatosus cutaneus superficialis is a rare idiopathic abnormality characterized by isolated dermal collections of adipose tissue. The lesions usually are either congenital or present by the third decade of life and occur predominantly in the pelvic-girdle area. We saw a case that was unusual because the nodules present arose in the patient's fifth decade of life and were confined to the abdominal wall. Histopathologic examination of the nodules showed mature adipose tissue, perivascular mononuclear cell infiltrates, and numerous mast cells. By electron microscopy, we observed small mature lipocytes within the perivascular mononuclear infiltrates. However, neither lipoblasts nor the transition of mesenchymal cells to lipocytes could be demonstrated.
浅表性脂肪瘤样痣是一种罕见的特发性异常，其特征为真皮内孤立的脂肪组织聚集。这些损害通常为先天性或在生命的第三个十年出现，主要发生在骨盆带区域。我们见到一例不寻常的病例，因为出现的结节是在患者生命的第五个十年出现的，且局限于腹壁。结节的组织病理学检查显示有成熟的脂肪组织、血管周围单核细胞浸润以及大量肥大细胞。通过电子显微镜检查，我们在血管周围单核浸润内观察到小的成熟脂肪细胞。然而，未发现成脂细胞，也未证实间充质细胞向脂肪细胞的转变。
