Abstract
We present a rare case of intraoral atypical lentiginous melanocytic lesion affecting a pediatric patient, in which the diagnosis of lentiginous junctional melanocytic nevus with cytologic atypia was favored. The main differential diagnosis is lentiginous melanoma, which is a slowly progressing lesion, affecting mainly older adults, and microscopically presenting lentiginous growth pattern of moderately atypical melanocytes, with focal nesting and pagetoid spread. It is strongly recommended that melanocytic lesions showing features of atypical lentiginous growth pattern should be treated with wide excision; however, the impact of these guidelines on pediatric patients needs to be better defined with the report of further cases.

Abstract
Oral pigmented lesions have a wide range of clinical presentations, some of which correlate with cutaneous pigmented lesions. This article highlights these correlates and underscores important differences that can potentially have clinical impact. Moreover, given a nonspecific presentation of an oral pigmented lesion, the article provides a reference to aid clinicians with differential diagnoses based on clinical features. This article is an overview of pigmented lesions of the oral cavity, including localized reactive pigmented lesions, neoplastic pigmented lesions, and pigmented lesions as sequelae of a systemic disease.

[PMID: 32223052 DOI: 10.1111/odi.13335] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2019] [Revised: 02/27/2020] [Accepted: 03/18/2020] [Indexed: 12/14/2022]
Abstract
OBJECTIVES To assess potential association between oral nevi (ON) and nevus-associated melanoma (NAM), in which melanoma cells coexist with nevus cells. METHODS A total of 74 ON patients and 7 NAM patients were retrospectively reviewed. Comparative and regression analyses of clinical and histological data were performed between two groups. RESULTS The mean age of the patients with ON was 36.5 years compared with that of 54.7 years of the patients with NAM (p = .008). Gender ratio was female predominance for ON (1.64:1 ratio) and male predominance for NAM (6:1 ratio). The most common location of ON and NAM was the palate (31.1%) and gingiva (71.4%), respectively. Univariate regression analysis revealed that elderly male patients (≥60 years) with junctional ON located on the gingiva correlate with higher risk of melanoma. Multivariate analysis revealed that junctional type of ON was an independent factor (adjusted OR, 38.32; 95% CI, 3.20-458.64; p = .004) associated significantly with increased risk for melanoma. CONCLUSIONS The preliminary study for the first time elucidated the clinicopathologic features of a Chinese series of ON and evaluated the potential association between ON and NAM with a limited sample size. Further large multicenter studies are needed to confirm the findings.
