T-cell-predominant lymphoid hyperplasia in a tattoo

Abstract

Cutaneous lymphoid hyperplasia (CLH) can be idiopathic or secondary to external stimuli, and is considered rare in tattoos. The infiltrate can be predominantly of B or T-cells, the latter being seldom reported in tattoos. We present a case of a predominantly T CLH, secondary to the black pigment of tattooing in a 35-year-old patient, with a dense infiltrate of small, medium and scarce large T-cells. Analysis of the rearrangement of T-cells receptor revealed a polyclonal proliferation. Since the infiltrate of CLH can simulate a T lymphoma, it is important to show that lesions from tattoos can have a predominance of T-cells.

Red tattoo‐related mycosis fungoides‐like CD8+ pseudolymphoma

“…Pseudolymphomatous reactions to tattoo are rare and are most commonly B‐cell predominant . T‐cell pseudolymphomas from tattoo are rarely reported, with one prior case report of tattoo‐related T‐cell lymphoid hyperplasia . Cases of tattoo reaction mimicking MF appear to be extremely rare and to our knowledge this is the first reported case of a tattoo‐related T‐cell predominant MF‐like pseudolymphoma.…”

Light treatments of nail fungal infections

“…Phenothiazinium PSs for onychomycosis treatment have been investigated in a small number of clinical studies (Table 1). Figueiredo Souza et al conducted a case study of 4 patients for endonyx onychomycosis [46] as well as a larger randomized controlled clinical trial of 80 patients [27] using a 2% MB aqueous solution. In both studies, a total of 12 PDT sessions were carried out over 6 months.…”
