Schamberg's disease: involvement of the genitalia.

516 sinuses and crusts. The skin over the entire foot was hyperpigmented and thickened; regional lymph nodes did not show any significant enlargement, and systemic examination was unremarkable. All the routine investigations, including foot radiographs and hematological and biochemical tests, were within normal limits. A few black, irregular granules of variable size measuring 0.5 to 2 mm were collected from the patient and subjected to microscopy and culture. Potassium hydroxide (KOH) wet mount revealed brown-colored, septate hyphae approximately 2 × 4 μm in width, interwoven with each other. On Sabouraud’s dextrose agar (containing chloramphenicol without cycloheximide), black-colored colonies with white aerial hyphae were isolated after 1 week of incubation. Microscopically, lactophenol cotton blue wet mount of the colony showed erect, unbranched, septate, flexuous, brown-colored conidiophores, along with conidia. The conidia were approximately 20-30 × 8-10 μm in size, smooth walled, olivaceous brown in color, were four-celled with 3 septae and had a larger sub-terminal cell [Figure 1]. The fungal isolate was identified as Curvularia lunata. The patient was treated with oral itraconazole 200 mg twice daily. The patient started improving as shown by the reduction of swelling with resolution of the sinuses. He is currently under observation with continued medical treatment.
