2015
Byline: Maithreyi. Poguri, Nitya. Damodara, Priya. Sivashankar, Siva. Nambi Sir, Senear–Usher syndrome refers to a combination of lupus erythematosus and pemphigus foliaceous.[sup][1] Treatment of this condition usually comprises of steroids and immunosuppressants. However, occurrence of Senear–Usher syndrome with bipolar disorder has been very rarely described. The occurrence of these two conditions throws up many clinical challenges.[sup][2] We describe the case of a lady with Senear–Usher syndrome with bipolar disorder that posed difficulty in clinical management. A 32-year-old married lady was brought to our hospital with complaints of disturbed sleep and irritable mood for 1-week.

At the time of presentation, the patient was on stable doses of steroid. Dermatological opinion was obtained for the presence of skin manifestations of SLE. Well-defined erythematous plaques were present over the trunk, back, abdomen, upper limb and lower limbs. Malar rash was present, as were hypopigmented patch with pigmented borders and atrophy. Oral mucosal ulcer with lip ulcer was also present. A diagnosis of SLE with pemphigus erythematosus was made, the combination of which refers to Senear–Usher syndrome. Dexamethasone and cetrizine were started for the skin conditions. The presence of Senear–Usher syndrome with bipolar disorder posed challenges for management.
