Non-erythematous lesions
Published in Richard Ashton, Barbara Leppard, Differential Diagnosis in Dermatology, 2021

Poikiloderma is identified by the combination of pigment, atrophy and telangiectasia. Poikiloderma of Civatte is the commonest type and occurs in middle aged and older patients on the sides of the neck. The skin becomes a mottled red-brown colour with atrophic areas. The area immediately under the chin and ears is spared. It is thought to be due to UV exposure, possibly associated with cosmetics acting as photo-sensitisers. It is very common and patients rarely bring it to the attention of their doctors. No treatment is available other than using a sunblock.
Monographs of fragrance chemicals and extracts that have caused contact allergy / allergic contact dermatitis
Published in Anton C. de Groot, Monographs in Contact Allergy, 2021
For information on testing patients with psoriasis (53), individuals suspected of photodermatoses (123), children (84; there are many such studies not mentioned here), physical therapists (50), patients with pure allergic hand dermatitis (54), with poikiloderma of Civatte (131) and with facial allergic contact dermatitis (79) please consult table 3.126.4. In the studies in patients with poikiloderma of Civatte (131), with pure allergic hand dermatitis (54) and with facial allergic contact dermatitis (81) the frequency of sensitization may have been elevated, but in the latter two, the patients were selected on the basis of relevant reactions (54,81).

In poikiloderma of Civatte, the pigmentation is reticulated, reddish to brown, with irregular and symmetrical distribution, affecting the hemifaces, neck, and upper third of the chest, and sparing the shaded chin area. It is frequently accompanied by superficial atrophy and telangiectasias.

In this study, we measured the melanin indices after the IPL and PDL treatments and reported statistically significant improvement of pigmentation in both treatments. IPL has been widely used to treat pigmentary disorders including melasma (21), solar lentigines and ephelides (22), poikiloderma of Civatte (23), and nevus spilus, café-au-lait macules, post-inflammatory hyperpigmentation, and Riehl’s melanosis (24), and all appear to respond reasonably well. With PDL, there have been studies on treating pigmentary disorders along with other treatments including triple combination cream (25) and 1927-nm fractional low-powered diode laser (26) but not of PDL alone. Melanocytes express vascular endothelial growth factor (VEGF) receptors 1 and 2 and neuropilin. Thus, VEGF and skin vascularization might play a role in pigmentation processes (27). In these cases, rosacea can be accompanied with pigmentary disorders such as melasmas, solar lentigines, and post-inflammatory hyperpigmentation. Compared with baseline, the erythema and melanin indices improved significantly after four treatments with both PDL and IPL, and there were no significant differences between treatments in either index. These results suggested that treatment with PDL only, not in combination with pigment-specific modalities, may improve lesions to address both the vascular and pigment components such as rosacea with melasma and melasma with telangiectasia.
