A mixed tumor is a neoplasm that has microscopic features of both epithelial and mesenchymal differentiation. Such mixed tumors are known as pleomorphic adenomas in the salivary glands, and their cutaneous counterparts are called chondroid syringomas. These tumors commonly occur in the head and neck region of middle-aged men. Hyaline cell-rich chondroid syringoma is a rare benign variant of chondroid syringoma composed of cells with eosinophilic hyaline cytoplasm and plasmacytoid features, the origin of which remains elusive. Although very few cases have been reported in literature, it is important to be aware of this entity so as to avoid misdiagnosis on histopathological examination. In this report we present a case of hyaline cell-rich chondroid syringoma occurring in the finger.
混合瘤是一种具有上皮和间充质分化微观特征的肿瘤。这种混合瘤在唾液腺中被称为多形性腺瘤，其皮肤对应物被称为软骨样汗腺螺旋瘤。这些肿瘤常见于中年男性的头颈部区域。富含透明细胞的软骨样汗腺螺旋瘤是软骨样汗腺螺旋瘤的一种罕见良性变体，由具有嗜酸性透明细胞质和浆细胞样特征的细胞组成，其起源尚不清楚。尽管文献中报道的病例很少，但认识到这种实体很重要，以便在组织病理学检查时避免误诊。在本报告中，我们展示了一例发生在手指的富含透明细胞的软骨样汗腺螺旋瘤病例。
