RESUMO
Being a rare inflammatory, hyperproliferative dermatosis, diagnosing pityriasis rubra pilaris (PRP) can be a challenge to many clinicians. Our case reports aim to demonstrate that PRP is frequently diagnosed and managed as atopic dermatitis (AD) and that distinguishing features on dermoscopy, and biopsy can help diagnose this rare disease. The study also aims to show that PRP can be successfully treated with Isotretinoin. Our case series aims to describe two cases of PRP, initially diagnosed as AD and managed with topical corticosteroids. Being the first case series in the literature to describe the incidences of diagnosing PRP as AD portrays the significance of utilizing dermoscopy and biopsy as tools to confirm this diagnosis for appropriate management. Although PRP is a rare diagnosis, dermoscopy and biopsy can help confirm the disease. Management with isotretinoin will most likely have successful outcomes in those patients.
RESUMO
Isolated bilateral periorbital edema with negative serology is an extremely rare presentation of cutaneous lupus erythematosus that may lead to eyelid scarring, infection, or even corneal involvement. The treatment usually comprises a combination of hydroxychloroquine and a tapering dose of systemic steroids. Patients require long-term follow-up as they may develop systemic lupus erythematosus with positive serology later in life. We report a case of a 32-year-old female who presented with chronic bilateral periorbital edema, and the histopathology confirmed cutaneous lupus erythematosus.
