“…In agreement with previous studies, our cases were found mainly in young patients (mean age 20 years) as nodular lesions, all exhibiting blue colour both clinically and dermoscopically (Table ). However, PEM appear to present as polymorphic lesions dermoscopically, characterized by homogeneous blue pigmentation and a variable combination of black, brown and white colour . This description suggests a differential diagnosis from common blue naevus and melanoma .…”

“…). In those cases exhibiting only a structureless blue pigmentation, or homogeneous blue and crystalline structures, the lesions were excised because they were reported as growing . In the other cases, the combination of blue and black colour was the key feature that led to excision.…”

“…In conclusion, the diagnostic evaluation of a blue lesion should always rely on the integration of all data, including patient’s age, duration of onset and rate of growth of the lesion, palpability and dermoscopic features [1]. Other noninvasive techniques, like RCM and HD-OCT can also be important aids in the differential diagnosis of a blue lesion.…”

The colors that are seen in dermoscopy depend on the anatomic level of the skin at which the chromophores are seen. Blue color can be found in a variety of melanocytic and nonmelanocytic lesions.An 89-year-old man presented with a 3-year history of a slow-growing, hyperpigmented patch located on the distal third of the right arm. Dermoscopy showed an atypical network, irregularly distributed globules, pigmented internal streaks and a milky-red area. Based on these findings a diagnosis of slow-growing malignant melanoma was made. Simultaneously, a well-defined blue papule was seen on the proximal third of the same arm. Dermoscopy disclosed a homogeneous blue pattern. After clinical and dermoscopic correlation our differential diagnosis for this blue lesion included cutaneous melanoma metastasis, blue nevus and foreign body reaction. The patient recalled its onset 75 years ago after a grenade explosion. We also discuss the blue lesion appearance under reflectance confocal microscopy and high-definition optical coherence tomography. Histopathological examination after excision of the hyperpigmented patch and blue papule revealed a melanoma in situ and a foreign body reaction, respectively.The diagnostic evaluation of a blue lesion should always rely on the integration of all data, especially clinical and dermoscopic features. Other non-invasive techniques, like reflectance confocal microscopy and high-definition optical coherence tomography can also be important aids for its differential diagnosis.

“…La coloración final de los pigmentos del tatuaje variará dependiendo de la composición química del pigmento y su localización anatómica dentro de la piel, a la cual se suman los colores de los diferentes cromóforos que existen en la epidermis y dermis, incluyendo melanina, hemoglobina y colágeno.

RESUMENEl tatuaje es un tipo de modificación cultural del cuerpo que consiste en insertar tinta dentro de las capas dérmicas a través de una aguja u otro material. La práctica del tatuaje causa un trauma en la piel con el objetivo de ejecutar un diseño conocido, cuyo resultado es una marca indeleble en el cuerpo. Este artículo analiza las consecuencias paleopatológicas del tatuaje en un conjunto de momias tatuadas del periodo Paracas Necrópolis procedentes del Cementerio de Warikayan, localizado en la costa sur del Perú. A partir de los resultados obtenidos de los análisis bioarqueológicos, complementados con los análisis de tatuajes mediante microscopia óptica, fluorescencia de rayos X y reflectografía infrarroja, se localizan los tatuajes y se inspeccionan en busca de lesiones derivadas de la práctica de modificación cultural. Los resultados indican que el 43% de los individuos Paracas analizados tiene tatuajes. Las localizaciones más frecuente para los tatuajes eran el dorso y la palma de la mano (21%), los dedos de la mano (16%) y el antebrazo (14%), Se ha encontrado una prevalencia de tatuajes considerablemente alta en mujeres. El pigmento utilizado es el carbón y debido a la similitud de los diseños tatuados con aquellos registrados en mantos textiles y vasijas cerámicas de la cultura Paracas, es posible pensar que los tatuajes están relacionados con el estatus social.Palabras clave: Tatuajes, Paracas, Necrópolis, paleopatología, tejido blando ABSTRACT Tattoos are intentional body modifications that describes the implantation of pigment into the dermis by a needle or other material. Tattooing cause trauma to the skin in order to execute a specific design. The result is an indelible mark in the skin. This article analyzes the paleopathological implications of tattooing and presents the results of the optical microscopy analisys, X-ray fluorescence and infrared Reflectography performed on a set of tattooed mummies from the Paracas Cemetery of Warikayan, located on the southern coast of Peru. All individuals analyzed are from the Paracas Necropolis period. The results indicate that 43 % of the Paracas population had tattoos. The most common locations for tattoos were the hand (21%), the fingers (16 %) and forearm (14%). There was a significantly high prevalence of tattoos on women. The pigment used is coal. The similarity of the designs tattooed with those recorded in textiles and ceramic Paracas suggest that tattoos were associated with social status before they used as medical therapy
