How I Healed my Psoriasis
Eruptive PV in its early stages can be indistinguishable from early PR. This diagnosis must always be considered in a patient with a positive family history for PV. In general, PV will progress unless treated, and as the lesions mature they develop the deeper color and loose silvery scale typical of that disease. Eruptive PV should always be considered with fixed PR. Usually PV lacks a herald plaque and the classic Christmas tree pattern. At this stage, the biopsy findings are generally inconclusive. A short period of observation will usually spare the victim the discomfort, scar, and expense of biopsy. As with SD, the presence of nail pitting favors a diagnosis of psoriasis. Discoid and subacute lupus erythematosus (LE) can occasionally resemble PV in onset, distribution, and lesional morphology. Lupus lesions usually have a deeper hue with telangectasias. Scarring, which is absent in psoriasis, tends to occur early in discoid LE. Arthralgias and systemic symptoms may be present,...
Configuration represents the shape of the lesion as it is seen from above. Common types of configurations include nummular (coin sized and shaped), gyrate, annular (ring-like border with some degree of clearing in the center), and linear lesions. Most lesions have a circular configuration. A few lesions are oval, notably those of pityriasis rosea, and many others are irregular in shape. Examples of irregular shapes include gyrate and serpigenous lesions, which generally occur due to the melding of adjacent lesions that are enlarging in a centrifugal manner until they reach the point of confluence. Such lesions are frequently found, for example in psoriasis and urticaria. On the other hand, irregular lesions with angular or linear shapes generally occur as a result of external trauma such as scratching or are due to the direct inoculation of antigen (ocular medications) or virus (linear warts). Linear lesions (the shape, not the arrangement of a group of lesions) are special types that...
Classic Scalp, pressure points over extensor surface of joints, presacral and upper gluteal clefts, glans penis. Psoriasis may occur on any skin surface (see Fig. 8). Figure 8 Macrodistribution of psoriasis vulgaris. Figure 8 Macrodistribution of psoriasis vulgaris. 2. Inverse Creases and folds. An uncommon intertriginous form is referred to as inverse psoriasis. 3. Skin biopsy As noted above, PV can simulate several other inflammatory der-matitides. Unfortunately, the histology of SD can also show similar changes. For this reason, biopsy of PV is not always a definitive procedure and should not be undertaken routinely. If the disease is atypical, extensive, or refractory to treatment, the patient should be referred to a dermatologist to decide whether this expense is cost-effective. Biopsy readily distinguishes psoriasis from suba-cute lupus erythematosus. However, distinguishing PV from other diseases, especially cutaneous T-cell lymphoma, is tricky and requires special competence...
INTRODUCTION Squamous cell carcinoma is a malignant tumor that most commonly affects elderly, fair-skinned individuals. It arises from keratinocytes of the epidermis. Unlike the more common basal cell carcinoma, squamous cell carcinoma tends to arise in precancerous areas of skin alteration or in areas of skin damaged by chronic sun exposure, ionizing radiation, carcinogens (e.g., arsenic), psoralen plus ultraviolet A (PUVA) therapy for psoriasis, and the human papilloma virus. Intrinsic factors that may contribute to its development include xeroderma pigmentosum, oculocutaneous albinism, and immunodeficiency. Chronic skin dermatoses, inflammation, ulceration, and contracted scars also are associated with the development of this tumor. In fact, scarring of the skin is the most common intrinsic factor leading to this tumor in black patients. Lymphatic spread and perineural invasion are possible.
The noninfectious dermatidities seborrhea and psoriasis can both cause inflammation and scaling of the scalp, but do not cause patchy hair shedding. Both are more diffuse than TCa. When any inflammatory scalp condition does not respond promptly to treatment, a KOH exam and fungal culture of epilated hairs are indicated. Patches of nummular eczema, early lesions of psoriasis, patches of impetigo, pityriasis alba in its early inflammatory phase, and the herald patch of pityriasis rosea can all be confused with TC. When other diagnostic features of these conditions are absent, a simple KOH exam should distinguish them. Psoriasis, lichen planus, monilia of the nails, and other nondermatophyte fungal and yeast organisms that invade nail tissue must be distinguished from onychomycosis of the nails. Psoriasis may be clinically very similar. Fine linear pitting of psoriasis is not a feature of TU. Another helpful sign is the oil-spot change on the nail bed seen in psoriasis.
Scabies must be considered in the differential diagnosis of any generalized pruritic skin disorder especially with a history of nocturnal itching that interrupts sleep. Atopic dermatitis, generalized drug reactions, and widespread impetigo all show common features. A high index of suspicion that leads to a search for primary lesions is important to maintain. Crusted scabies can simulate eczema, psoriasis, or on rare occasions, an ery-throderma.
Another important achievement will be to understand the biological significance of the frequent PCR detection of HPV DNA sequences in premalignant or malignant tumors at nongenital sites, such as the skin, or in other diseases, such as psoriasis. This may lead to a broadening of the spectrum of HPV-associated diseases.

A loose white scale develops in some cases, and the lesions may simulate a papulosquamous disease. There is no follicular accentuation as in DLE, and the carpet-tack sign is negative. As the lesions evolve, they exhibit telangiectatic vessels and a dusky color not seen with pityriasis rosea or psoriasis. When the lesions regress they may leave mild epidermal atrophy, telangectasia, and hypopigmentation, but they do not scar. Annular lesions usually enlarge peripherally with a border that has erythema and loose white scale. The central areas show gray-white hypopigmentation. These lesions tend to coalesce to form polycyclic and gyrate patterns (see Chapter 2).

Polymorphisms in cytokine genes and cytokine pathway genes are associated with both CD and UC. Duerr and colleagues completed the first large-scale GWAS in IBD of 308,332 SNPs 68 . A non-synonymous SNP (rs11209026 Arg381Gln) in the interleukin 23R gene conferred significant protection against IBD. Heterozygous carriage of the glutamine allele confers an approximately threefold increase in protection against developing CD, with a more modest protective effect observed in UC. Several other SNPs within IL23R were also shown to be associated with ileal CD. Further replication studies for IL23R have been published in several adult and pediatric IBD cohorts but IL23R is also associated with autoimmune diseases including psoriasis 69 and ankylosing spondylitis 70 . IL23 is a regulatory cytokine expressed by natural killer (NK) cells, NKT cells, CD4+ T cells, CD8+ T cells, activated macrophages and DCs 71 . This heterodimeric cytokine discovered in 2000 72 is comprised of IL12p40 and an...
These have been reported with a large number of medications. Thiazide diuretics, gold, antimalarials, -blocking agents, vitamins, and NSAIDs are among those most commonly cited. This differential must be carefully evaluated in every case of LP. Some reactions are clinically identical to idiopathic LP however, subtle findings on routine biopsy may help to distinguish them. Immunopathology is not helpful. LP-like drug reactions resolve slowly and require a good deal of support and confidence on the part of the treating practitioner. Clinical features that help to distinguish the two include a photodistribution and a psoriasis-like appearance common with the drug-induced form.

To test whether or not high-density single nucleotide polymorphism (SNP) mapping could detect a susceptibility locus within a large region, GlaxoWellcome scientists constructed a SNP map of 2 megabases (mb) on either side of APOE (Lai et al 1998). We asked the question whether a SNP map analysis could detect the location of the APOE locus for AD, if we did not know it was there. The locus was narrowed to less than 100 kilobases (kb), which included the APOE locus, in a very short time frame. This process has since been employed within GlaxoWellcome for other disease susceptibility gene searches through large linkage regions, including psoriasis, diabetes mellitus, migraine, chromosome 12-linked AD and others. These experiments will define the practical density of SNP maps useful for narrowing the large linkage areas to 50 200 kb, containing far fewer candidate genes that could then be tested for disease association (Martin et al 2000).
Superficial BCCs occur frequently in areas with minimal light exposure, especially the trunk and lower extremities. Islands of basal cell lesions arise superficially in a multi-focal fashion from the base of the epidermis. They are often multiple and are sometimes encountered in fair-skinned persons with minimal evidence of lifetime sun exposure. In some instances, there is a prior history of arsenic exposure. These tumors are usually relatively flat red or red-brown plaques that enlarge peripherally and may reach a diameter of several centimeters. They may easily be mistaken for plaques of psoriasis, nummular eczema, or a Bowen's epithelioma. Careful examination with a hand lens will usually reveal a thready or discontinuous pearly border that suggests the correct diagnosis. Although exophytic tumors and deep extension can occur within these lesions, both are uncommon even with longstanding growths. Large exophytic areas often have little or minimal deep invasion.
DIFFERENTIAL DIAGNOSIS Few other disorders give the clinical picture of ichthyosis. Most notably the differential includes psoriasis, exfoliative dermatitis, collodion baby syndrome, harlequin fetus, Refsum's disease, Sjogren-Larsson syndrome, Conradi's disease, KID syndrome, and Trichothiodystrophy.
DIFFERENTIAL DIAGNOSIS The differential diagnosis includes malignant melanoma, sebaceous cell carcinoma, squamous cell carcinoma, actinic keratosis, radiation dermatitis, keratoacanthoma, cutaneous horns, dermoid and sebaceous cysts, eccrine and apocrine cysts, papillomatous lesions, seborrheic kertosis, blepharitis, chalazion, eczema, psoriasis, and seborrheic dermatitis.

Focusing more closely on discovery, we see that there are essentially five main steps target identification and validation, and lead identification, optimization, and validation. Figure 4.3 provides a description of these five steps. To illustrate these steps, we'll consider two different examples, a small molecule to treat AIDS and an antibody to treat psoriasis. The disease AIDS (acquired immunodeficiency syndrome) is caused by infection with HIV (the human immunodeficiency virus). Psoriasis is an autoimmune disease characterized by activated immune cells. Normally, the immune system acts as an internal security system, protecting the body from infection and injury. With psoriasis, however, T cells become overactive. This activity sets off a series of events that eventually make skin cells multiply so fast, they begin to pile up on the surface of the skin, forming characteristic plaques (red, scaly patches on the surface of the skin). Thus, agents that interfere with the function of...
Nonsteroidal anti-inflammatory drugs (NSAIDs) have been variously reported to flare or improve psoriasis. Because of their extensive use, a decision should be made in each case based on history of disease activity relative to the indication for the NSAID. A psoriatic patient starting one of these agents should be warned to report flaring promptly.
