“…Aetiopathogenesis of these lesions is still unknown, however, local trauma and chronic inflammation are considered as a possible inducing factor of melanotic macules. 27,28 Histologically, these lesions are characterized by the increased number of melanin in basal keratinocytes with normal number of melanocytes. 27,28 Clinically, melanotic macule is a brown to black, small (usually less than 1cm in diameter), flat, well-circumscribed, asymptomatic lesion.…”

“…About 91% of these lesion are located on the lower lip, whereas only 6% on the upper lip. 28,29 Other common locations are gingiva, palate and buccal mucosa. The glans penis and female genitalia may be other locations of melanocytic macules.…”

“…They are more common in women than in men and usually occur in fourth or fifth life decade. 28,29 Multiple labial and oral melanotic macules associated with linear streaks of nail pigmentation can be a symptom of Laugier-Hunziker syndrome. 30 Cases of multiple melanocytic macules have been reported in immunosuppressed patients.…”

Dermoscopy is a noninvasive diagnostic technique that permits the visualization of morphologic features that are not visible to the naked eye. It is currently widely used for examination of pigmented skin lesions and early detection of cutaneous melanoma. Dermoscopy of mucous membranes is significantly less investigated and less popular among clinicians.This article reviews current knowledge about characteristic dermoscopy features of pigmented lesions of the oral mucous membranes and lips. It has to emphasized that a major advantage of dermoscopy is the capability to exclude melanoma and avoid unnecessary excisional biopsies and extensive surgery, often resulting in significant disfigurement of face and oral cavity.It has to be pointed out that there is a necessity to intensify research, which would result in clear-cut dermoscopy criteria for mucosal melanoma and the need for constructing thin, flexible dermoscopes suitable for investigation of oral mucous membranes. Dermoscopy is a noninvasive diagnostic technique that permits the visualization of morphologic features that are not visible to the naked eye. It is currently widely used for examination of pigmented skin lesions and early detection of cutaneous melanoma. 1,2 Despite increasing popularity in examination of skin lesion, the methods remains unpopular in investigating pigmented lesions oral mucous membranes and lips. Dermoscopy of pigmented oral lesionsPigmented mucosal lesions represent a group of rare entities differing in etiopathogenesis, histology, dermoscopy and clinical course. Solitary pigmented lesions of melanocytic origin are uncommon in the oral mucosa. These lesions include the oral and labial melanotic macules, oral melanocytic nevi, oral melanoacanthomas and oral melanomas. 3 As shown by Buchner et al 4 oral and labial melanotic macules are the most common melanocytic lesions. The relative frequency of oral melanoma accounts for 0.6% of the entire melanocytic group of oral pigmented lesions (Table 1). Despite low frequency, early detection of melanoma is the main aim of dermoscopic examinations of the oral mucous membranes and the lip. An additional benefit of dermoscopy is exclusion of melanoma of the oral mucous membranes or the lip in doubtful cases, what may save patients the discomfort of extensive and unnecessary surgery.In this paper, we review current knowledge about dermoscopy of pigmented lesions localized on the mucous membranes of the oral cavity and the semi-mucosa of lips.

“…Discoloration of the oral mucosa can be commonly seen and is known to be associated with a variety of endogenous and exogenous etiologic factors [2]. Pigmented lesions of the oral cavity include a group of different entities, including melanocytic lesions, lesions due to foreign material deposition, vascular lesions, and salivary gland lesions [2,3]. In addition to the complexity of multiple etiologic factors, various stimuli can evoke the same tissue response and different conditions might share the same histopathologic features.…”

A 53-year-old female presented with a history of a black pigmented lesion in the left buccal mucosa associated with mild pain, first noticed 18 months previously. The patient had previously been prescribed an ointment for pain by her dentist that had brought about pain relief, however the pigmentation persisted. The patient, therefore, sought another opinion.Clinically, a few black spots were observed in the buccal mucosa with some redness around the lesion, however, there was no swelling or ulceration (Fig. 1). There were numerous yellow spots around the black spots. The oral surgeon performed a wide local excision.

“…Los cambios de coloración de la mucosa oral pueden ser de tres tipos: rojas, blancas o negras (5). En este tercer grupo se presentan lesiones de carác-ter fisiológico y localizadas exclusivamente en boca (pigmentación melánica o fisiológica), pigmentaciones orales asociadas a trastornos sistémicos (enfermedad de Addison y síndrome de Peutz-Jeghers), pigmentaciones inducidas por drogas, pigmentaciones neoplásicas (nevo oral, mácula melanótica oral o labial y melanoma maligno) y lesiones causadas por injuria sobre la mucosa bucal (reacción a cuerpo extraño o metales pesados, melanosis del fumador, melanoacantoma y tatuaje por amalgama) (8).…”

RESUMENEl tatuaje por amalgama también conocido como pigmentación por amalgama, es el producto del depósito en el tejido conectivo subepitelial de residuos de amalgama resultado de procedimientos iatrogénicos por parte del odontólogo. La presentación clínica varía dependiendo de la profundidad a la que se alberguen las partícu-las en el tejido, radiográficamente se puede identificar la radiopacidad correspondiente al fragmento de amalgama, en los estudios histopatológicos se pueden observar las partículas de amalgama como gránulos oscuros, sólidos e irregulares dispuesto entre los haces de colágeno y vasos sanguíneo. El presente artículo refiere un peculiar caso de tatuaje por amalgama de tonalidades azules y negras que se extendió difusa e irregularmente en toda la mucosa vestibular desde el órgano dentario 21 hasta región premolar izquierda. Al realizar una cirugía periodontal exploratoria se detectó una gran porción de amalgama utilizada como material obturador y restaurador radicular del 21. Durante el procedimiento quirúrgico se cureteó y adelgazó la cara interna del colgajo mucoperióstico para tratar de disminuir el grado de pigmentación.Palabras clave: Amalgama dental, tatuaje, argentum metallicum, trastornos de la pigmentación (DeCSBireme). SUMMARYAmalgam pigmentation or amalgam tattoo is the product of the deposit in the subepithelial connective tissue of amalgam was the iatrogenic result of procedures by the dentist. The clinical presentation varies depending on the depth at which the particles are housed in the tissue can be identified radiographically radiopacity fragment corresponding to the amalgam, histopathological studies particles can be observed as dark granules amalgam, provided solid, irregular between collagen bundles and blood vessels. The present article describes an unusual case of focal argyrosis shades of blue and black fuzzy and unevenly spread across the buccal mucosa from 21 to left premolar region. When performing exploratory periodontal surgery revealed a large portion of amalgam used as a restorative filling material and root of 21. During the surgical procedure and lost cureteo the inside of the mucoperiosteal flap to try to reduce the degree of pigmentation.
