Zosteriform Lichen Planus

Zosteriform Lichen planus

“…The lines do not correspond to any known nervous, vascular or lymphatic structures and differ clearly from the pattern of innervation of the spinal cutaneous nerves 16], However, the cases of peculiarly distributed lichen planus reported by several authors [9][10][11][12][13], as well as our patient, did not show a pattern fol lowing the lines of Blaschko, thus excluding genetic factors.…”

Superimposed segmental manifestation of polygenic skin disorders

“…[34][35][36][37][38][39][40]58 As a consequence, some investigators have even examined their patients for the presence of varicella-zoster virus. 49,68 The reports and photographs, however, clearly show that the arrangement was not zosteriform but followed Blaschko's lines.…”

Cutaneous reactions at sites of herpes zoster scars: an expanded spectrum

“…In contrast, lichen planus has previously been described at the sites of herpes zoster scars as zosteriform lichen planus. [31][32][33] These cases have been interpreted by different authors as a manifestation of Koebner's phenomenon, 52 as an expression of a viscerocutaneous reflex mechanism within the affected segments, 33,[53][54][55][56] as a radicular irritation caused by abnormalities of the vertebral column, 57 and as lichen planus arranged in a pattern following the lines of Blaschko. 58,59 In any event, lichen planus seems to appear with more extensive and hypertrophic cutaneous lesions in HIV-infected patients, 60 and patient 15 provides a good example of this.…”

“…Several types of cutaneous lesions have been described developing within resolved cutaneous herpes zoster lesions. These include comedones, 1 xanthomatous changes, 2 granuloma annulare, [3][4][5][6][7][8][9][10][11] sarcoidal granulomas, 12,13 tuberculoid granulomas, 14,15 granulomatous vasculitis, 16,17 unclassified granulomatous dermatitis, [18][19][20][21] tinea, 22 acneiform eruption, 23 furunculosis, 24 contact dermatitis, 24 nodular solar degeneration, 25 pseudolymphoma, [26][27][28] psoriasis, 29,30 lichen planus, [31][32][33] morphoea, 34 lichenoid chronic graftversus-host disease, 35 eosinophilic dermatosis, 36 acquired reactive perforating collagenosis, 37 lymphoma, 38,39 leukaemia, [40][41][42][43][44] Kaposi's sarcoma, 45 angiosarcoma, 46 basal cell carcinoma,…”

“…These cutaneous lesions may appear immediately in resolving vesicular lesions or at varying times after the acute eruption. The pathogenesis of the cutaneous reactions following resolved lesions of herpes zoster remains to be elucidated, and in the literature, type III or type IV hypersensitivity reactions 4,14 and Koebner's phenomenon 3,4,12,[31][32][33]45 have been proposed as provoking factors. The polymerase chain reaction (PCR) technique has been used to investigate the presence of varicella-zoster virus (VZV) DNA within these cutaneous reactions.…”
