  1. Koebner phenomenon appeared in our case after mechanical trauma. Because the patient had taken leflunomide for many years and the skin lesions appeared only 3 months before admission, we did not think leflunomide to be the cause of the rash. The pathogenesis of the Koebner phenomenon is still unclear
  2. Introduction. Koebner (isomorphic) phenomenon is defined as a non specific skin stimulus eliciting a disease skin reaction. Various diseases exhibiting this interesting phenomenon include psoriasis, lichen planus, erythema multiforme, vitiligo, warts, molluscum contagiosum, pyoderma gangrinosum, pityriasis rubra pilaris and so on. The prototype of the isomorphic response, however, occurs in.
  3. Koebner phenomenon (KP) refers to the development of isomorphic lesions in the traumatized area of normal skin in certain skin diseases. Recently Koebner phenomenon has further been subdivided into two classes: KP-h (KP from history) and KP-e (experimentally induced KP). But in both the cases only external trauma can induce this phenomenon
  4. The isomorphic response of Koebner, named after Heinrich Koebner (1838-1904), is a well-known phenomenon commonly associated with psoriasis. It has also been described in conjunction with a host of other disorders. It involves the development of lesions in previously normal skin that has been traumatized either externally or internally
  5. The Koebner phenomenon is the development of isomorphic pathologic lesions in the traumatized uninvolved skin of patients who have cutaneous diseases. These new lesions are clinically and histopathologically identical to those in the diseased skin. This phenomenon has been described in various dermatoses including LP. However, the appearance of.

Koebner phenomenon into four different groups:4 1. True isomorphic phenomenon: There appear to be three disease processes that display the true isomorphic response of Koebner: psoriasis, lichen planus and vitiligo; 2. Pseudoisomorphic phenomenon: The Koebner phenomenon seen in infectious diseases, e.g. warts, molluscum contagiosum and Behcet' What is the cause of the Koebner phenomenon? The cause of the Koebner phenomenon is unclear. Current theories suggest the Koebner phenomenon requires both epidermis and dermis to be injured at the same site. The production of inflammatory substances and neuropeptides has been postulated as a non-specific first step, triggering a secondary disease-specific process Renbok phenomenon (Inverse Koebner) Renbok phenomenon was described in a patient suffering from two autoimmune diseases, i.e. psoriasis and alopecia universalis. [55] It is a well-known fact that psoriasis is a T-cell-mediated disorder, while alopecia universalis is a B-cell-mediated condition In Koebner phenomenon, there is a development of similar cutaneous lesions in the setting of an already existing dermatosis, following any trauma; whereas in Wolf's isotopic response, there is a development of a new dermatosis localized to the particular site of a previously healed dermatosis without appearance of those similar lesions. As the distribution of the lines is linear, these were earlier thought to represent Koebner phenomenon, but the curvature of the lesions does not support this hypothesis. The lines of Blaschko are less well defined on the head and neck. The anatomic equivalent of Blaschko's lines has been described in the teeth and eyes as well

Koebner's phenomenon from history (Kp-h) and test grafting were the only available indicators to assess stability. It is quite ironic to note that even after four decades of experience in vitiligo surgery, there seems to be little consensus among workers regarding the optimal required period of stability within a surgical scar in a non-diabetic patient: Type III Koebner phenomenon (isomorphic response), Wolf's isotopic response or Ruocco's immunocompromised cutaneous district?.Indian J Dermatol Venereol Leprol 2017;83:233-23 Koebner phenomenon (KP) refers to the development of isomorphic lesions in the traumatized area of normal skin in certain skin diseases.2 Recently Koebner phenomenon has further been subdivided into two classes: KP-h (KP from history) and KP-e (experimentally induced KP). 3 But in both the cases only external trauma can induce this phenomenon The Koebner phenomenon indicates the disease activity was present in 53.85% cases.

What is a lichenoid drug eruption?. Lichenoid eruptions are uncommon skin rashes that can be induced by many environmental agents, medications or industrial by-products such as inhaled particles.

Mini-grafting test or test-grafting: The original test was proposed by Falabella et al.[1] to select patients with stable vitiligo who may respond to melanocyte transplantation. The test was considered positive i typical lesions as a part of Koebner's phenomenon. However, true linear psoriasis in the absence of lesions elsewhere is extremely rare[1] and it may be confused with inflammatory epidermal nevus or Koebner's response of psoriasis on verrucous epidermal nevus.[2] The lesions were clinically and histologically similar to psoriasis vulgaris may occur in scars as a result of Koebner™s phenomenon, inoculation of infectious agents, metastases or long-Table 1: Dermatoses which result in scars I.

Granuloma annulare may be a delayed hypersensitivity reaction to a component of the dermis or a reaction pattern to numerous triggers. Reported triggering events have included many skin infections and infestations, and types of skin trauma. Inflammation is mediated by tumour necrosis factor alpha ( TNF α). The reason this occurs is unknown Koebner phenomenon, which is positive in vulgaris type. Moreover, electron microscopic studies have confirmed that the hypopigmentation is not post-inflammatory, and so the vitiligo occurring during treatment of alopecia areata may not be due to distant spreading of DPCP.[15 6.

Background . Vitiligo is not a well-studied disease in Ethiopia. Therefore, this study assessed its clinico-epidemiological profile and treatment patterns. Methods . An institutional-based cross-sectional study was conducted in conveniently selected dermatologic clinics of Mekelle city, Ethiopia. A two-phased study was conducted, in which the first was to determine prevalence of vitiligo while. Koebner Phenomenon is positive in this case. The patient scratched both upper arms, waist, and lower limbs due to severe itchiness. Some of the scratched lesions merged into large ones .

Psoriasis is a long-lasting autoimmune disease characterized by patches of abnormal skin. These skin patches are typicallyred, itchy, and scaly. They may vary in severity from small and localized to complete body coverage.

[Epub ahead of print]. Systemic and local treatments for cancer can cause a number of changes in the skin, mucous membranes, hair, and nails [ 1-6 ]. When dermatologic lesions arise in patients being treated for cancer, they may represent a side effect of therapy, but other etiologies need to be considered. These include a cutaneous reaction to other drugs. Though the duration of stability is a debatable issue, the Indian Association of Dermatologists, Venereologists, and Leprologists (IADVL) task force has defined stability as 'a patient with no new lesions, no progression of existing lesions and absence of Koebner phenomenon during the past one year'
