We report the case of a left inguinal lymph node enlargement in a young man. A tattoo was present in close proximity to the lymph node and had preceded its enlargement by several years. The lymph node was removed surgically, and pathologic examination showed it to contain dark pigment material characteristic of a tattoo. The clinical significance of this finding is discussed, and the relationship of tattoo lymphadenopathy to inflammatory skin reactions and to dermatopathic lymphadenopathy is considered.
"Some studies suggest a possible mechanism however, no experimental studies have been performed on this mechanism  . Tattoo is known to cause lymphadenopathy in the acute phase  . This is thought to be due to local inflammation from the initial insult. "
[Show abstract][Hide abstract] ABSTRACT: Background: Previously described methods for removal of tattoos are chemical, mechanical, surgical, termal and laser assited methods. Invention of the Q-switch mode, advanced the laser method, to be one of the most effective methods of tattoo removal. Objective: Comparing the tattoo removal and rate of lymphatic elimina-tion of 3 different wavelengths of Q-switched Nd-YAG laser (532nm, 1064nm, combination 532 + 1064). Methods: In this study we examined lymphatic elimination and the effect of 532 nm, 1064 nm, and the com-bination (532 + 1064 nm) wavelength of laser pulse for the possible lymphatic cleansing mechanism of black pigmented tattoos. This study was performed on 18 New-Zealand rabbits, black pigmented tattoos were en-graved on the back and the four extremities of the animals. 532 nm wavelength of Q switched Nd: YAG la-ser beam was applied on the left upper and bilateral lower extremities of the rabbits. During this period, ex-cisional skin biopsies and lymph node biopsies were performed on days 7, 14 and 21. Results: Day 21 lymph node biopsies revealed mixed type of reactive hyperplasia and intracellular pigments were markedly seen in the laser treatment group and no intracellular tattoo pigment was seen in the control group. Conclusion: The findingd of this study indicate that lymphatic elimination may be one of the significant mechanisms of tattoo removal and the application of different wavelengths of Q-switched Nd-YAG laser do not show statistically significant differences in tattoo removal.
[Show abstract][Hide abstract] ABSTRACT: The knowledge of the chemical composition of the most commonly used pigments is necessary for the diagnosis of some cases of contact eczemas caused by tattoos. Several techniques of chemical analysis and characterization were used to study the materials involved in a permanent tattooing process such as pigments, solvents, needles and specially in the metals contained in them. A battery of patch tests is proposed that includes some substances characterized in the analysed pigments.
[Show abstract][Hide abstract] ABSTRACT: Body adornment through tattooing and body piercing and the use of recreational drugs are on the increase, producing a variety of secondary lesions, the etiology of which often remains undetected, as the medical community is not yet aware of the extent of the morbidity of such procedures and practices. Three cases are presented, which underscore the problem and also the role that fine-needle aspiration (FNA) can play in clarifying the etiology of such lesions. Two of these cases were lymphadenopathies, one secondary to tattooing and the other to tongue piercing, while the third was a deep intranasal lesion, which in all probability had resulted from intranasal use of recreational drugs. Although the clinical diagnosis of these lesions was problematic, the FNA performed by a pathologist, by associating the cytologic findings with the corresponding clinical setting, was quite indicative of their relation to the aforementioned procedures or practices.
