Pyogenic granuloma is thought to represent an exuberant tissue response to a local irritation or trauma. It is a reactional response to constant minor trauma and it might be related to hormonal changes. Clinically, these lesions usually present as single nodules or sessile papules with smooth or lobulated surfaces. These may be seen in any size, from a few millimetres to several centimetres. Pyogenic granuloma of the oral cavity is known to involve the gingiva more commonly (75% of all the cases). An extragingival occurrence of pyogenic granuloma is rare. This paper has described an extragingival pyogenic granuloma which occurred on the upper labial mucosa in a 30 years old female patient.
脓性肉芽肿被认为是对局部刺激或创伤的一种过度组织反应。它是对持续轻微创伤的一种反应性反应，可能与激素变化有关。临床上，这些病变通常表现为单个结节或有蒂丘疹，表面光滑或呈分叶状。其大小不一，从几毫米到几厘米不等。已知口腔脓性肉芽肿更常见于牙龈（占所有病例的75%）。牙龈外发生脓性肉芽肿很罕见。本文描述了一名30岁女性患者在上唇黏膜发生的牙龈外脓性肉芽肿。
