Aim. To describe morphology of local reactions to tattooing. Material and Methods. In the Moscow Scientific and Practical Center of Dermatovenerology and Cosmetology of the Department of Public Health in the period from 2014 to 2018, 57 patients were observed with the complaints about poor quality of tattoo and discomfort. A needle biopsy of the skin of the tattoo area was performed. The obtained 180 samples were subjected to histological examination with the use of hematoxylin and eosin, in addition to van Gieson’s staining. Results and Discussion. In the tattoo area of all the samples, the pigment distribution was irregular and was detected as a deposition of granules of various sizes in the papillary layer of dermis. Of 180 samples, 79 samples (43.9%), showed the fraying dermal fibers and fiber destructurization and immaturity. This corresponded to the morphological characteristics of the keloid. Of 180 samples, 30 samples (16.7%), demonstrated the atrophic changes of epidermis, smoothing of epidermal ridges, hyperkeratosis and acanthosis. In addition, the areas of papillomatosis were identified. Their pathohistology corresponded to the pemphigoid type of lichen ruber planus. Of 180 samples, 21 (11.7%) showed the pathohistological features of nevus, 32 (17.8%) showed the various types of benign neoplasm (dermatofibroma, papilloma, keratoacanthoma), 3 (1.6%) showed squamous cancer, and 2 (1.1%) showed malignant melanoma. The local allergic reactions were observed single and in combination with the other complications in 63 (35%) samples. Conclusions. The described pathohistological changes can be reliably attributed to the local complications of tatooing.
