Abstract
Erythema nodosum leprosum (ENL) is an immune complex-mediated response in Mycobacterium leprae infection, presenting with fever, arthralgias, and tender cutaneous lesions. It mimics Sweet syndrome (SS) clinically and histologically but requires distinct management. A 65-year-old man with recent travel presented with fever and edematous plaques. Initial findings supported SS, improving with corticosteroids. Symptom recurrence and a contact's leprosy diagnosis led to further testing, revealing M. leprae through repeat staining and tissue PCR. This case underscores the need to consider ENL in Sweet-like cases with relevant travel history. Repeat staining and molecular testing are essential for accurate diagnosis and treatment.
期刊介绍:
Journal of Cutaneous Pathology publishes manuscripts broadly relevant to diseases of the skin and mucosae, with the aims of advancing scientific knowledge regarding dermatopathology and enhancing the communication between clinical practitioners and research scientists. Original scientific manuscripts on diagnostic and experimental cutaneous pathology are especially desirable. Timely, pertinent review articles also will be given high priority. Manuscripts based on light, fluorescence, and electron microscopy, histochemistry, immunology, molecular biology, and genetics, as well as allied sciences, are all welcome, provided their principal focus is on cutaneous pathology. Publication time will be kept as short as possible, ensuring that articles will be quickly available to all interested in this speciality.
