Thymic endocrine tumor is a rare, malignant, primary thymic neoplasm originating from neuroendocrine cells, presenting as a mass within the anterior mediastinum. Patients typically present with nonspecific symptoms, such as chest pain, cough, shortness of breath, or in some cases, superior vena cava syndrome, although patients could be asymptomatic during the early stages or present with multiple endocrine neoplasia type I. Ectopic production of ACTH and serotonin can lead to Cushing syndrome and carcinoid sydrome, respectively.
Features include always present findings: Neoplasm of the thymus and Neuroendocrine neoplasm; and very common findings: Abnormal mediastinum morphology and Mediastinal lymphadenopathy. 24 total HPO annotations.
Organ System | Phenotype Count | Example Features |
