A 30-year-old male patient hailing from Bihar, India, presented with multiple hypopigmented hypoesthetic patches over his trunk along with the pictured erythematous skin lesion with a punched-out centre.
The ‘swiss cheese’ pattern is consistent with mid-borderline leprosy.
Diagnosis can be confirmed via skin biopsy for histopathology, and slit-skin smear for bacterial index (Bl) and morphological index (MI).
After confirming the diagnosis, multi-drug therapy (MDT) should be initiated according to the type/grading of leprosy.
