[Pheochromocytoma in multiple endocrine neoplasia 2A associated with pulmonary tuberculosis presenting as abdominal pain: a case report and literature review].

Pheochromocytoma is a catecholamine-producing neoplasm that may occur sporadically or associated with hereditary diseases, such as multiple endocrine neoplasia. The classic symptoms are headache, sweating, and palpitations and are attributed to the sympathetic nervous system activity, usually presenting as paroxysms. On the other hand, pulmonary tuberculosis is an infectious disease considered a public health problem in many countries, whose incidence depends on risk factors such as immunosuppression. It is well known that endocrine-tumor diseases such as multiple endocrine neoplasia can predispose to chronic inflammation and immunosuppression. We report the case of a 38-year-old male patient who had an episode of arterial hypertension and abdominal pain as the first symptoms of a pheochromocytoma associated with multiple endocrine neoplasia type 2A. The patient developed pulmonary tuberculosis simultaneously, but we managed to treat both entities and achieve a favorable clinical course.
