Queensland Pregnant Woman’s Rare Autoimmune Rash Identified as Pemphigoid Gestationis

Diagnosis and Symptoms
At 35 weeks pregnant, 32-year-old Robby MacDonald-Camden of Queensland sought care at an Obstetrics Review Center after an intensely itchy, hive-like rash spread from her arm to her abdomen and later blistered on her leg. Initial treatment with a steroid cream and antihistamine proved ineffective, and the rash became inflamed, hot to the touch, and painful to walk. A skin biopsy performed by dermatologists confirmed pemphigoid gestationis, a rare autoimmune blistering disorder.
Medical Explanation
Dermatologist Debra Jaliman, a board-certified specialist at the Icahn School of Medicine at Mount Sinai, explains that the condition occurs when the immune system attacks collagen XVII, a protein that links the epidermis to the dermis. The resulting disruption produces a very itchy rash, often with blisters around the belly button, that can spread over days to weeks across the trunk, arms, and legs. Jaliman notes that pemphigoid gestationis affects roughly one in every 50,000 pregnancies.
Patient Perspective
She expressed relief upon receiving a diagnosis and high-dose steroid tablets, yet remained confused about why the condition had not appeared in her first pregnancy and worried about escalating discomfort. After giving birth, the rash began to ease within two days, and the affected skin is now scabbing and fading without new flare-ups.
