Case report: The case presented initially with bands of green pigmentation of all primary teeth in a pattern that followed the time of their calcification, with those formed earlier being more severely affected. Fading of the green pigmentation was detected during the follow-up, while erupted lower permanent incisors were normal. Histological findings of an exfoliated primary incisor showed a green line at the enamel-dentine junction with the external surface of the dentine showing a band of variable width and irregularly arranged tubules. Conclusion: Bilirubin green pigmentation of primary teeth follows a chronological pattern and its intensity fades with time. Overlying enamel in affected areas may appear thinner.

A CBCT of the maxilla revealed a multilocular radiolucency, with ill‐defined borders, causing destruction of the buccal and palatal cortical bone.ResultsComplete removal of the tumour was performed under general anaesthesia. Healing was uneventful and there was no evidence of recurrence in the 36 months clinical and radiographical follow up. The final diagnosis was an odontogenic tumour with bland cytology, sclerosis and neural involvement, consistent with SOC.ConclusionsThe tumour presented herein showed clinical, radiographical and microscopical features consistent with SOC and COdF, with neural involvement favouring a diagnosis of SOC. Epithelial neurotropism in a COdF could account for the similarities between those lesions and the rather quiescent, for an infiltrative intraosseous carcinoma, clinical behaviour of SOC.

Material y Metodos: se recogieron retrospectivamente 1187 casos de agrandamientos gingivales localizados diagnosticados durante un periodo de 20 anos. El sexo y la edad de los pacientes, asi como las principales caracteristicas clinicas de los tumores se obtuvieron de los informes de biopsia. Resultados: De las 19,044 biopsias realizadas durante el periodo de estudio, los 1187 agrandamientos gingivales localizados representaron el 6,23%, correspondiendo a 756 mujeres y 427 hombres con una edad media de 41,92 ± 19,68 anos. Las lesiones se presentaron como tumoraciones lisas (52,4%), granulares (17,9%) o rugosas (13,16%), de consistencia elastica (50,73%) o blanda (29,56%) y de color rojo (60,8%), normal (28,58%) o blanco (8.17%). La mayoria de las lesiones (85,17%) fueron de origen reactivo, siendo el granuloma piogeno el mas comun. En el 1,1% de los casos se realizo un diagnostico de lesion maligna. Conclusiones: Se debe realizar un estudio histologico de todos los agrandamientos gingivales localizados porque aproximadamente el 1% de los casos son malignos.
