Granuloma faciale (GF) is a rare chronic dermatosis with still unknown etiopathology, which usually presents a solitary, asymptomatic, smooth reddish-brown to violaceous plaques or nodules on the face. Various therapeutic approaches, including topical application of corticosteroid or tacrolimus and removal with laser, cryotherapy and surgery have been attempted; however, the outcome has been inconsistent. Herein, we report a case of perinasal nodular GF who repeatedly underwent surgical excisions after the failure of laser treatment. Despite its nomenclature, GF does not manifest granulomatous tissue and the lesion is histopathologically characterized by dense dermal cell infiltration devoid of granulomatous changes and not distinguished by a clear border, which partially explains the difficulty of complete removal in our case. Review of the published work delineated that GF could be largely divided into two clinical subsets: plaque and nodular types. The plaque type GF could be responsive to topical tacrolimus, an approach preferentially adopted nowadays, while nodular type GF was often resistant to topical therapies and required surgical or laser removal. The latter subset often arose around the nose. For this location, surgical excision with sufficient removal margin is sometimes technically difficult when an aesthetically acceptable outcome is expected, explaining the basis for local recurrence. Postoperative recurrence could be observed after years of disease-free period. These observations indicated that the need for respective treatment strategies for the management of distinctive GF subsets. Of note, a multidisciplinary approach combining radical resection and additional supportive intervention with long-term follow up may be required for perinasal and nodular GF.
颜面肉芽肿 (GF) 是一种罕见的慢性皮肤病,其发病机制尚不清楚,通常表现为面部单发、无症状、光滑的红棕色至紫红色斑块或结节。已经尝试了各种治疗方法,包括局部应用皮质类固醇或他克莫司以及激光、冷冻疗法和手术切除;然而,结果并不一致。在此,我们报告了一例鼻部结节性 GF 患者,在激光治疗失败后反复接受手术切除。尽管它被命名为肉芽肿,但 GF 并不表现出肉芽肿组织,病变的组织病理学特征是致密的真皮细胞浸润,没有肉芽肿改变,并且没有明确的边界,这部分解释了我们病例中完全切除的困难。对已发表文献的回顾表明,GF 可大致分为两种临床亚型:斑块型和结节型。斑块型 GF 对局部他克莫司治疗有反应,这是目前优先采用的方法,而结节型 GF 通常对局部治疗耐药,需要手术或激光切除。后一种亚型通常发生在鼻子周围。对于这个位置,如果期望获得美观的结果,手术切除并充分切除边缘在技术上有时很困难,这解释了局部复发的基础。在疾病无复发多年后可能会观察到术后复发。这些观察结果表明,需要针对不同的 GF 亚型制定相应的治疗策略。值得注意的是,对于鼻部和结节性 GF,可能需要结合根治性切除和长期随访的额外支持性干预的多学科方法。
