Erythrocyte sedimentation rate: Usually normal, except in pustular and erythrodermic psoriasis, where it may be elevated along with the white blood cell count. Afebrile (except in pustular or erythrodermic psoriasis, in which the patient may have high fever). If left untreated, acute erythrodermic psoriasis and generalised psoriasis may become life threatening. Psoriasis is generally not life threatening in most cases but it causes some inconvenience 6.
Keywords: Kaposi’ varicelliform eruptions, psoriasis herpeticum, varicella zoster virus. Kaposi’s varicelliform eruption (KVE) or eczema herpeticum is characterized by disseminated papulovesicular eruption usually caused by viruses like herpes simplex virus (HSV) I and II, coxsackie virus, and vaccinia and small pox viruses in patients with pre-existing skin disease. 3,4 We report a case of psoriasis herpeticum following herpes zoster thoracis in a patient with erythrodermic psoriasis. SIGNS AND SYMPTOMS: Worsening of a long term erythematous scaly area Sudden onset of many small areas of scaly redness Pain, especially in cases of: – Erythrodermic psoriasis – Traumatized plaques – Joints affected by psoriatic arthritis Pruritus, especially in the case of: – Eruptive psoriasis – Guttate psoriasis Afebrile state, except in cases of: – Pustular psoriasis – Erythrodermic psoriasis Dystrophic nails Long term rash, with recent presentation of joint pain Stiffness, pain, throbbing, swelling/tenderness of joints. Increases usefulness of phototherapy – Generally used as 2nd line drug therapy, due to messy application (except shampoos). Up to 40 of people with skin psoriasis have some signs of psoriatic arthritis. Joint symptoms may flare with a flare in skin psoriasis but quite commonly the skin symptoms behave independently of joint symptoms. Elevated ESR and CRP (erythrocyte sedimentation rate and C-reactive protein, respectively), which are markers of inflammation, may reflect the severity of the inflammation in the joints.
Erythrocyte sedimentation rate (ESR) is usually normal (except in pustular and erythrodermic psoriasis). Patients with guttate, erythrodermic, or pustular psoriasis may present to the emergency department. T lymphocyte counts are within the normal range, and a minimum of a 12-week interval has passed since the previous course of treatment. Laboratory examinations including rheumatoid factor were negative or normal except for elevation of the erythrocyte sedimentation rate and c-reactive protein in 2 cases. Ichthyosiform erythroderma associated with generalized pustulosis. Psoriatic nail involvement is common and usually accompanies other associated cutaneous or systemic lesions.
