Oral common blue nevus is an asymptomatic, benign, rare, pigmented lesion and sometimes clinically indistinguishable from other pigmented lesions such as the cellular blue nevus or early-stage malignant melanoma. Since it shows clinical similarities with a malignant lesion and with cellular blue nevus that can itself suffer malignant transformation, the decisive diagnosis is crucial for adequate treatment, follow-up, and prognosis. Diagnosis confirmation is given by histological analysis, the reason why most oral pigmented lesions are excised. The following case presents an asymptomatic oral pigmented lesion of the hard palate discovered during observation in an emergency setting due to an abscess of dental origin. The lesion was fully excised, and histological examination reported a "common blue nevus." In this case, we intend to present a rare lesion of the oral cavity and the importance of performing a routine oral examination when given a chance as a preventive approach.
口腔普通蓝痣是一种无症状的良性罕见色素性病变，有时在临床上与其他色素性病变难以区分，如细胞性蓝痣或早期恶性黑色素瘤。由于它与恶性病变以及本身可能发生恶性转化的细胞性蓝痣在临床特征上相似，因此明确诊断对于恰当的治疗、随访及预后至关重要。组织学分析可确诊，这也是大多数口腔色素性病变被切除的原因。以下病例是在因牙源性脓肿进行急诊观察期间发现的硬腭部无症状口腔色素性病变。该病变被完整切除，组织学检查报告为“普通蓝痣”。在此病例中，我们旨在呈现一种罕见的口腔病变，并强调在有机会时进行常规口腔检查作为预防措施的重要性。
