We describe the largest reported case of pilomatrixoma in the literature. While pilomatrixomas typically present as small soft-tissue nodules of the head, neck and upper extremities, they can also present as much larger masses in atypical locations. When they present in their usual size, pilomatrixomas have typical imaging features and can be correctly diagnosed with imaging studies before histological confirmation. Their clinical and imaging diagnosis become challenging when they are very large, as in our case. A giant pilomatrixoma should also be considered for paediatric patients presenting with a large subcutaneous soft-tissue mass.
我们描述了文献中报道的最大的毛母质瘤病例。虽然毛母质瘤通常表现为头、颈和上肢的小软组织结节，但它们也可能在非典型部位表现为大得多的肿块。当毛母质瘤以其通常大小出现时，具有典型的影像学特征，在组织学确诊之前通过影像学检查即可正确诊断。当它们非常大时，如我们的病例，其临床和影像学诊断就变得具有挑战性。对于出现大的皮下软组织肿块的儿科患者，也应考虑巨大毛母质瘤的可能。
