The practice of tattoo is developing more and more all over the world. Infections are known. but chronic inflammatory reactions have often resulted in a variety of clinical manifestations. In addition to allergic reactions, non-allergic reactions prevail in black tattoos and manifest themselves as "papulonodular" lesions. The importance of biopsy of papulonodular lesions to confirm the diagnosis should be emphasized. Carbon black nanoparticles agglomerate in the dermis over time to form sarcoid granulomas. Pigment-bound foreign-body granuloma and sarcoidosis are often difficult to distinguish. The black color seems to be the most common. Other aetiologias than pigment are evoked, such as the role of an infectious agent, but to date none has been identified, a particular genetic terrain remains to be defined. Systemic localizations being possible, the extension assessment is important to carry out. It is also important, as a preventive measure, that subjects and their treating physician be informed of the potential risk associated with these drugs indicated for specific serious pathologies.
纹身行为在全球范围内愈发普遍。感染情况已为人所知，但慢性炎症反应常常导致各种临床表现。除过敏反应外，黑色纹身中以非过敏反应为主，表现为“丘疹结节性”病变。应强调对丘疹结节性病变进行活检以确诊的重要性。随着时间推移，炭黑纳米颗粒在真皮层聚集形成结节病肉芽肿。色素结合性异物肉芽肿和结节病常常难以区分。黑色似乎最为常见。除色素外，还引发了其他病因，如感染因子的作用，但迄今为止尚未确定任何感染因子，特定的遗传因素仍有待明确。由于可能出现全身性定位，进行扩散评估很重要。作为预防措施，让受试者及其治疗医生了解针对特定严重病症所使用这些药物的潜在风险也很重要。
