Plexiform schwannoma is an uncommon benign neoplasm of the neural sheath characterized grossly and microscopically by multinodular growth. It is typically presented as a mobile, solitary, smooth-surfaced, and nontender mass. Histologically, schwannomas are classified into the following seven types: classical (Verocay), plexiform, cellular, cranial nerve, melanotic, degenerated (ancient), and granular cell schwannomas. In spite of the fact that plexiform schwannoma commonly occurs in the head-and-neck region, the involvement of the lip is considered to be extremely rare. Herein, we present the case of a 16-year-old boy with the schwannoma on the lower lip excised without any recurrence at 9 months after surgery.
丛状神经鞘瘤是一种罕见的神经鞘良性肿瘤，其大体和显微镜下特征为多结节生长。它通常表现为可移动的、孤立的、表面光滑且无压痛的肿块。组织学上，神经鞘瘤分为以下七种类型：经典型（Verocay型）、丛状型、细胞型、颅神经型、黑色素型、退化型（陈旧型）和颗粒细胞型神经鞘瘤。尽管丛状神经鞘瘤常见于头颈部区域，但唇部受累被认为极为罕见。在此，我们报告一例16岁男孩下唇神经鞘瘤的病例，术后9个月切除，无任何复发。
