Figure 2: At exploration, the surface marking guided the incision over the forearm (a) along the swellings (1–3). It revealed the thick purulent material getting disgorged; the same is depicted on deep dissection (b). Preoperative ultrasonography (c, double arrow) and magnetic resonance imaging (d, arrows) of the forearm demonstrate the nerve abscesses. Photomicrograph of nerve the biopsy showing infiltration by lymphocytes and foamy macrophages (e, arrow) (Hematoxylin and eosin, ×400), and a single lepra bacillus (f, arrow) (Modified Ziehl–Neelsen, ×1000)
