Pruritus: Generalized or abdominal pruritus sometimes develops during pregnancy. This is attributed to endocrine, toxic, neurogenic cause or hepatic dysfunction. Prurigo gestation is a special form of generalized pruritus, appears as numerous pruritic papules with bloody crusts on the extensor surface of limbs, abdomen and chest. Other causes of pruritus viz. jaundice, diabetes or any skin disease are to be ruled out. Treatment is unsatisfactory. Lotions as described under vulval pruritus, sedatives and antihistamines can be tried for some relief. The condition disappears after delivery.
Herpes gestationis: This is considered peculiar to the pregnancy as it has a tendency to recur in the successive pregnancies. Generalized pruritus is followed by appearance of grouped erythematous papules, vesicles on abdomen, thighs, breasts, legs and forearms. Eosinophilia may be present. Corticosteroid can be given orally, and as local ointment.
Impetigo herpetiformis: This rare fatal skin disease has been described as being associated with pregnancy. The manifestations are confluent pustular eruptions on groin, thigh, breast, axillae with fever, joint pain and delirium. Oral mucosa show grayish white patches. Termination of pregnancy results in recovery. General supportive measures such as antibiotics, corticosteroids, soothing lotions are useful.
