Striated muscle hamartoma (SMH) is an uncommon benign lesion, that is usually congenital, polypoid, and primarily located on the head and neck. The key histopathologic sign is the existence of individualized fascicles of striated muscle affecting the dermis and subcutaneous fat tissue. Here we report the case of a newborn girl with an SMH, who presented with a congenital infiltrated plaque on her chin without any other associations.
横纹肌瘤（SMH）是一种罕见的良性病变，通常为先天性，呈息肉样，主要位于头颈部。关键的组织病理学特征是存在影响真皮和皮下脂肪组织的单个横纹肌束。在此，我们报告一例患有SMH的新生儿女孩病例，她出生时下巴出现先天性浸润性斑块，无其他相关症状。
