We report a case of cutaneous swelling found on the left anterior axillary fold of a 41-year-old man. Gross examination of specimen excised from the dermis showed a well-circumscribed nodule histologically composed of spindle cells with interspersed ganglion cell like cells. On hematoxylin and eosine (H and E) staining it was diagnosed as ganglioneuroma. Ganglioneuromas are rare, benign, fully differentiated tumors that contain mature schwann cells, ganglion cells, fibrous tissue, and nerve fibers. They are commonly found along the paravertebral sympathetic ganglia and sometimes in the adrenal medulla. However primary cutaneous ganglioneuroma is an extremely rare tumor. Immunohistochemical workup revealed a fibroblastic origin and hence the case was diagnosed as fibromatosis with ganglion cell like fibroblasts. This case report suggests that the features considered diagnostic of ganglioneuromas can occur in other cutaneous lesions and, therefore, this diagnosis cannot be offered only on the basis of H and E.
我们报告一例发生于一名41岁男性左腋前皱襞处的皮肤肿胀病例。对取自真皮的切除标本进行大体检查显示,有一个边界清楚的结节,组织学上由梭形细胞和散在的神经节样细胞组成。苏木精-伊红(H&E)染色后诊断为神经节神经瘤。神经节神经瘤是罕见的良性、完全分化的肿瘤,包含成熟的施万细胞、神经节细胞、纤维组织和神经纤维。它们通常沿椎旁交感神经节分布,有时也见于肾上腺髓质。然而,原发性皮肤神经节神经瘤是一种极其罕见的肿瘤。免疫组织化学检查显示其起源于成纤维细胞,因此该病例被诊断为伴有神经节样成纤维细胞的纤维瘤病。本病例报告提示,被认为是神经节神经瘤诊断特征的表现也可能出现在其他皮肤病变中,因此,不能仅基于H&E染色做出该诊断。
