Mycetoma is a chronic, suppurative, granulomatous disease of the subcutaneous tissues and bones.[1] Mycetoma can be eumycetoma (due to fungi) or actinomycetoma (due to bacteria).[2]

A 36-year-old male, farmer by occupation, presented with swelling of the left foot for 4 years. He was a known case of type-2 diabetes mellitus on oral medication. Over the past 4 years, swelling progressed with multiple draining sinuses. Pain was not associated with the swelling.

On examination, a massive hyperpigmented swelling with multiple sinuses extending from the lower third of left leg to the dorsum of the foot [Figure 1]. The discharge was yellowish-white in color and blood tinged with yellowish-white grains observed after 24 h of occlusive dressing.

Histopathological examination revealed hyperplastic stratified squamous epithelium with underlying tissue showing mild inflammatory infiltrate and hemorrhage [Figure 2]. No fungal elements were seen. Microbiological staining revealed Gram-positive, periodic acid–Schiff-negative and acid-fast-positive organisms [Figure 3]. The sample cultured on Sabouraud dextrose agar yielded no growth. X-ray of the left foot showed osteolysis of tarsals and metatarsals. Computed tomography scan revealed soft tissue edema with thickening in the distal leg region along with foot chronic infective inflammatory pathology.

The patient was clinically diagnosed as a case of mycetoma based on clinical triad, and based on microbiological investigations, a final diagnosis of actinomycetoma due to Nocardia. He was admitted in the Dermatology, Venereology, and Leprosy Ward and started on antibiotic therapy. Exploration, drainage of sinus tracts, and debridement of diseased tissue were done along with the initiation of parenteral antibiotics.
