This case report describes a rare case of a young girl with coexisting Takayasu arteritis and leishmaniasis infection. The patient's condition was controlled, but complications of Takayasu arteritis arose during treatment.
Takayasu arteritis (TA) is a rare large-vessel vasculitis that can result in significant morbidity and mortality. The coexistence of TA with leishmaniasis infection has not been reported previously. Case description: An 8-year-old girl presented with recurrent skin nodules that heal spontaneously for four years. Her skin biopsy revealed granulomatous inflammation with Leishmania amastigotes identified in the histocyte cytoplasm and the extracellular space. The diagnosis of cutaneous leishmaniasis was made and intralesional sodium antimony gluconate was started. One month later, she experienced dry coughs and fever. The CT angiography of the carotid arteries showed dilation in the right common carotid artery and thickening of artery walls with elevated acute phase reactants. The diagnosis of Takayasu arteritis (TA) was made. Reviewing her chest CT before treatment, a soft-tissue density mass was identified in the right carotid artery region, suggesting a pre-existing aneurysm. The patient was treated with surgical resection of the aneurysm with systemic corticosteroids and immunosuppressants. Her skin nodules resolved with scars after the second cycle of antimony while a new aneurysm arose due to a lack of control of TA. Conclusions: This case highlights that benign as the natural course is for cutaneous leishmaniasis, fatal comorbidities can occur as a consequence of chronic inflammation, and can be aggravated by the treatment.
