The blood supply to the mycetoma lesion and its vasculature were studied in patients with various types of mycetoma using histological, ultrastructural, angiographic and sonographic techniques. The mycetoma lesion proved to be well vascularized. However, certain vascular abnormalities were demonstrated. In histological sections, the small arteries and arterioles showed medial muscular hypertrophy in 83%, intimal fibrosis in 33%, arteritis in 7% and endarteritis obliterans with narrowed lumen in 7% of the patients. No vascular occlusion, ischaemic changes or arteriovenous shunts were observed. These changes were confirmed ultrastructurally. Angiography of the lesion showed a brisk pathological circulation which was more evident in eumycetoma. The vascular Doppler study showed normal blood flow pattern in the affected limb. Regional intra-arterial chemotherapy for mycetoma is suggested as a possible treatment modality.
