A case of a 73-year-old woman with a history of von Recklinghausen disease (neurofibromatosis type 1) who presented initially with a gradual onset of shortness of breath and lightheadedness with no associated fever, chills, angina, palpitations, cough, weight loss, night sweats, nausea, vomiting, or constipation. She was found to be severely bradycardic and in third degree atrioventricular block by her primary care physician. She was admitted in the hospital because of intermittent bouts of lightheadedness and progression of the shortness of breath. Twelve-lead electrocardiogram documented the high grade atrioventricular block. Chest radiograph showed subtle mild pulmonary congestion. Transthoracic echocardiogram revealed mild concentric hypertrophy and normal systolic function with no regional wall motion abnormalities or evidence of significant valvular disease. Pacemaker was inserted and her symptoms improved significantly.

Pheochromocytomas are rare catecholamine-secreting neuroendocrine tumors that can occasionally progress to life-threatening disease, including a multisystem crisis. Patients with Neurofibromatosis type 1 (NF1) may develop pheochromocytomas, and the consequent chronic elevation of plasma catecholamine levels could further complicate various cardiovascular and pulmonary manifestations they may have. A 37-year-old African American female with NF1 presented with severe dyspnea, chills, myalgia, vomiting, and abdominal pain. Within several hours of hospital admission, she developed progressive agitation and died from circulatory collapse. An autopsy revealed disseminated histoplasmosis with necrotizing granulomatosis in her lungs, mediastinum, liver, and spleen, as well as bilateral pheochromocytomas with one tumor showing marked hemorrhage. Additionally, she had cardiac hypertrophy, myocarditis, pulmonary edema, apical bullae, features of pulmonary hypertension and interstitial fibrosis. Disseminated histoplasmosis caused by the fungal organism Histoplasma capsulatum is rarely described in immunocompetent individuals. This case is presented to illustrate that chronic hypercatecholaminemia caused by pheochromocytomas may potentially mask disseminated fungal infections which in turn could induce pheochromocytoma multisystem crisis in susceptible patients with neurofibromatosis.
