Management of Psoriasis Herpeticum in Pregnancy: A Clinical Conundrum

الملخص EN

Introduction.

Kaposi varicelliform eruption (KVE) is a widespread cutaneous viral infection, most commonly herpes simplex virus, which affects patients with underlying dermatosis.

When KVE occurs in a patient with a history of psoriasis, it is referred to as psoriasis herpeticum, a rare subtype of KVE with only a handful of cases reported in the literature.

To the authors’ knowledge, we report for the first time a case of psoriasis herpeticum in pregnancy.

Case Presentation.

A 23-year-old woman in her third pregnancy presented at 26-week gestation with a 10-year history of psoriasis.

Cutaneous examination revealed diffuse psoriatic plaques with scattered ~1 cm erosions.

Punch biopsy of the skin revealed herpes simplex virus (HSV) infection within a psoriatic plaque, necessitating dermatological treatment.

The patient experienced premature rupture of membranes at 37-week gestation.

Pelvic exam showed no evidence of herpetic lesions.

After labor augmentation, the patient delivered a healthy female infant with no evidence of HSV infection.

Discussion.

Psoriasis herpeticum is a rare and potentially devastating complication of an underlying dermatosis.

With a paucity of data available to guide pregnancy-specific issues, the general management of this condition is controversial and requires a multidisciplinary care approach.

Concerns for systemic infection in the mother and vertical transmission to the neonate are of critical importance.
