Psoriasis and related disorders

Impetigo herpetiformis

          Pustular psoriasis started at the second trimester of first pregnancy three years ago and resolved after delivery. Few exacerbations occurred when the patient had used contraceptive pills. At this pregnancy it has reoccurred with the onset at second trimester with many grouped pustules on erythematous bases involved the trunk mainly the abdomen of this 30-year-old woman.

Acrodermatitis continua suppurative

Acrodermatitis continua suppurative2

History

          The relation of acrodermatitis continua suppurative (Hallopeau) to psoriasis is controversial. However, some consider it as a localized form of psoriasis characterized by pustules limited to one or a few fingertips including the nail bed. Nail loss is not uncommon. Here we present a typical case of acrodermatitis continua of Hallopeau characterized by chronic inflammation and pustulation confined to one finger (thumb) with nail loss of more rhan three years duration.

Palmar psoriasis

History

          A 38-year-old man presented with asymptomatic, bilateral symmetrical, well-demarcated, red scaly plaques confined to both palms of many years duration with sustained exacerbations and exceptional remissions.

Unilateral pustular psoriasis

History

          A middle-aged woman presented with strikingly unilateral asymptomatic, grouped pustules, scaliness and brownish hyperpigmentation confined to the middle portion of one sole. Her condition was characterized by exacerbations and remissions of more than one year duration. It is differentiated from pustular bacterid  by being asymptomatic, unilateral, normal WBC count and there was no focus of remote infection.
