Mélanomes sur tatouage : deux observations et revue systématique de la littérature

Keratoacanthomas and Squamous Cell Carcinomas on Tattoos: A Review of 42 Cases

“…The literature failed thus far to provide robust argument supporting a non-fortuitous association for MMs and BBCs [2]. The lack of multiple lesions within one tattoo and the overall low number of cases plead for a background noise rather than causality [3]. A malignant or premalignant lesion can also be inadvertently tattooed over, and its evolution masked by the drawing.…”

Histopathology of Dermatologic Complications of Tattoos

“…Thirty-four cases of melanoma arising because of a tattoo have been reported to date. 29 A male predominance (90, 3% of cases) and a younger age at diagnosis (45, 9 years) compared with other patients with melanoma has been noticed. Among the reported cases, 71% of melanomas developed on dark blue or black tattoos; and the time between tattooing and the development of melanoma is usually several years, often decades.…”

“…However, a possible multifactorial carcinogenic role has been hypothesized as follows: tattoo injection–associated trauma and tattoo inks (in their native form or after exposure to ultraviolet radiation) may act as local carcinogens and may play a role in the development of skin neoplasms. 28 Moreover, most of the reported cases of melanoma developed on dark blue or black tattoos, 29 whereas SCC and keratoacanthomas occurred on red tattoos. 7 Chronic ultraviolet exposure also influences tattooed skin carcinogenesis because tattoos are commonly placed on visible areas and therefore often photo-exposed.…”

“…In this review, we summarized the main histopathologic findings of cutaneous complications secondary to tattoos (Table 1). 1–30,31–60,61–89 Incidental changes, such as acantholytic dyskeratosis (Fig. 4) or epidermolytic hyperkeratosis (Fig.…”

Could wide tattoo delay the early diagnosis of cutaneous melanoma?

“…Nevertheless, there do not seem to be elements that support the role of one or the other colour in the development of skin cancers. 8 Our aim is to point out the attention on the risk for delay diagnosis of melanoma in patients with wide tattoos. Indeed, we suggest a screening at time 0 (before tattoo) by archiving iconographic documentation of the skin and a more tightening follow ups should be attempted, especially in case of very wide tattoo.…”
