Cutaneous Melioidosis Presenting as a Red Nasal Plaque: A Case Report.

BACKGROUND

Melioidosis, caused by , is endemic to tropical regions. Cutaneous forms, often presenting as non-healing ulcers, are rare and may mimic other skin diseases. Recognizing risk factors is key to prompt diagnosis and treatment.

CASE PRESENTATION

We report the case of a 51-year-old female with a 2-month history of chronic erythematous plaques on her nose. Aerobic tissue culture confirmed the diagnosis of primary cutaneous melioidosis by identifying . There was no evidence of systemic involvement, and blood culture results were negative. The patient was successfully treated with oral sulfamethoxazole-trimethoprim monotherapy. After three months of treatment, the lesion resolved completely, leaving an atrophic scar. At the eight-month follow-up, there was no evidence of recurrence.

CONCLUSION

This case illustrates an atypical presentation of cutaneous melioidosis without systemic involvement, which was effectively treated with oral sulfamethoxazole-trimethoprim monotherapy. A comprehensive evaluation to exclude dissemination is critical for ensuring successful treatment outcomes.
