A follow-up study failed to find picornavirus RNA in patients with pityriasis rosea. With resolution of the eruption, postinflammatory pigment changes can be observed. These features may closely resemble erythema annulare centrifugum, guttate psoriasis, superficial gyrate erythema, and small plaque parapsoriasis. Hand dermatitis can range from an acute, extremely pruritic or painful eruption, characterized by deep-seated vesicles (dyshidrotic eczema, pompholyx), to a chronically rough, hyperkeratotic hand dermatitis. Herpes zoster (VZV): usually vesicular & see viropathic epidermal change. recall reaction, viral: mostly reported in VZV cases but not a viral recurrence; maybe triggered as a pruritic reaction with mixed interstitial & perivascular lymphs & eosinophiles. Of the more than 85, 000 chemicals in our environment, many can be irritants and more than 4350 have been identified as contact allergens. ICD follows exposure to chemical or physical substances capable of direct damage to the skin. Pruritus is a hallmark of most forms of contact dermatitis. Morphology of lesions (erythema, eczema, lichenification, pigmentary changes, urticaria, etc.).
This article will guide the nurse in assessing patients with a skin condition. Further, because a dermatological condition may be life-long, needs will change with age. Example: psoriasis. It may be this post-inflammatory pigmentation that brings the patient to the dermatologist. Itching (pruritus) is the principal symptom of dermatological disease and also occurs in numerous systemic disorders. Provide scheduled follow-up to assess treatment response. Pruritus can be moderate to severe in up to half of patients. Guttate psoriasis can mimic PR, but does not have the characteristic collarette of scale.
Postinflammatory pigment changes can be observed. Both hypopigmentation and hyperpigmentation can follow the rash. In this chapter, the discussion will be limited to those common skin diseases that show evidence of inflammation in the dermis and hyperkeratosis or desquamation of the epidermis. The clinical expression or lesion of psoriasis is the result of inflammation in the dermis and vascular changes leading to hyperproliferation and abnormal differentiation of the epidermis. In guttate or eruptive psoriasis, 0.1-1.0 cm, red, droplet-shaped lesions appear predominantly on the trunk and proximal extremities. Inflammatory scalp conditions with pruritus may require the addition of a medium potency topical corticosteroid in an oil or hydroalcoholic vehicle, e. You do a thorough examination and find only a pigmented lesion present on his left back. The lesions usually follow the lines of skin cleavage (called Christmas tree pattern). If present, severe pruritus can be treated with a mid-potency topical corticosteroid. The patient has guttate psoriasis, which may be triggered by sunburn or streptococcal infection.

Post-inflammatory (many inflammatory dermatoses can leave hypopigmented areas of skin). In pigmented skin lesions may be hypopigmented or hyperpigmented / raspberry-like papillomas arising at junctions between the mucosa and skin). Disease in patients with pigmented skin can present a diagnostic challenge to the clinician because of differences in clinical presentation, as well as some dermatoses being unique to certain ethnic groups. Clinical services have also been affected by changing epidemiological trends in skin disease in the UK, particularly the dramatic increase in incidence of tinea capitis in African-Caribbean children in urban areas. Keloids can be symptomatic, patients often complain of pruritus or tenderness. Post-inflammatory hyperpigmented macules are the dominant and frequent sequelae. Follow Us:. Psoriasis is not a cancer, but does seem to be related to the immune system. Psoriasis causes cells to build up rapidly on the surface of the skin, forming thick silvery scales and itchy, dry, red patches that are sometimes painful. Psoriasis is often so mild it is barely noticed by the affected person, but it can occasionally so severe the patient must be admitted to hospital for treatment. The pigmentary changes gradually improve over several months. They can be congenital, with different patterns of inheritance, or acquired in consequence of skin problems, systemic diseases or secondary to environmental factors. Particularly prominent aspects of diagnosis and therapy will be emphasized, with focus on melasma, post-inflammatory hyperpigmentation, periorbital pigmentation, dermatosis papulosa nigra, phytophotodermatoses, flagellate dermatosis, erythema dyschromicum perstans, cervical poikiloderma (Poikiloderma of Civatte), acanthosis nigricans, cutaneous amyloidosis and reticulated confluent dermatitis. 3,43 The most common causes of PIH are: acne, atopic dermatitis, allergic contact dermatitis or secondary to irritants, trauma, psoriasis, lichen planus, drug eruptions, and nowadays, cosmetic procedures. It’s not always listed in those lists of autoimmune diseases that can be put into full remission by a paleo diet (it is listed in The Paleo Answer, but not The Paleo Diet nor The Paleo Solution). The first and most important step is to follow the paleo diet autoimmunity protocol. Is there anything we can do to get rid of the post-inflammatory hypo pigmentation after a lesion clears? Thankfully I was able to clear my paoriasis using The Myers Way (very similar to AIP), but I still have white spots on my legs 6 months later. Since then, I’ve made drastic changes in my life and now my stress is minimal. Erythema multiforme is a skin condition of unknown cause; it is a type of erythema possibly mediated by deposition of immune complexes (mostly IgM-bound complexes) in the superficial microvasculature of the skin and oral mucous membrane that usually follows an infection or drug exposure.

There are a number of eruptions involving the trunk that can cause diagnostic confusion. The course is generally benign and healing complete, although patients should be informed that post inflammatory pigmentation changes may persist.
