Predominantly affecting male workers in endemic regions, mycetoma typically manifests as painless swelling evolving into purulent lesions with draining sinuses in the extremities. Although historically uncommon in regions like North America, rising immigration and international travel have led to an increased prevalence, necessitating heightened clinical suspicion. Early diagnosis is crucial to prevent severe complications such as limb loss and septicemia. This case report details the diagnosis and management of chronic actinomycetoma due to Nocardia spp. in a Guatemalan immigrant landscaper and emphasizes the importance of comprehensive understanding and timely intervention in mycetoma cases.
