Mixed Lichenoid and Follicular T- and B-Cell Lymphoid Reaction to Red Tattoos With Monoclonal T Cells

Adverse effects related to tattoos in the community setting: a systematic review

BACKGROUND

Tattoos were historically associated with deviant behaviours or religious and other social purposes, but in the last decades, they have gained increasing popularity and have become a mainstream. The aim of this systematic review is to assess the literature evidence about decorative tattoos complications, considering both infective and non-infective risks.

METHODS

This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement. We searched the following electronic bibliographic databases: PubMed, Scopus and Web of Science (science and social science citation index).

RESULTS

The literature search resulted in 6473 studies. A total of 207 full articles were considered potentially relevant and were reviewed independently by researchers. After full-text evaluation, 152 of 207 articles were excluded, as they did not meet selection criteria. The remaining 55 studies were included in the systematic review and their quality assessment was performed. Ten studies reported microbiological complications, 37 reported non-microbiological effects and eight reported either microbiological and non-microbiological complications.

CONCLUSIONS

Several well-known and uncommon risks are associated with tattooing and tattoo after-care. Public health authorities could take into account health education programmes for tattooists and customers in order to prevent health complications in people with tattoos.

Lymphoma or pseudolymphoma: A report of six cases and review of the literature

To explore and compare the clinical presentations and pathologic features of cutaneous pseudolymphomas (CPL) with primary cutaneous lymphomas. Review literature in order to improve the treatment of CPL. Six cases of CPLs were collected. The clinical, pathologic, and immunohistochemical features were performed and analyzed in Peking Union Medical College Hospital in 2018. Of six patients, the distributions and clinical manifestations of skin lesions are varied. The pathologic features consisted of atypical prominent lymphocytes infiltration. Of them, two cases imitated mycosis fungoides, one case mimicked primary cutaneous aggressive pidermotropic CD8+ cytotoxic T-cell lymphoma, one case was diagnosed as Jessner-Kanof lymphocyte infiltration and two cases primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder. With respect to etiology, one was result from insects bite and the others were on account of drugs. All cases were treated with systemic or local glucocorticoid. The skin lesions and systemic symptoms showed notable improvement after treatment. Follow-up visits were 2 years, half a year, and months, respectively, without relapse. These unique types of CPL were similar to cutaneous lymphomas in clinical manifestation and pathology. They were all sensitive to the treatment of externally or orally using glucocorticoid. The prognosis is generally good but needs long-term follow-up.
