Pulmonary fibrosis - hepatic hyperplasia - bone marrow hypoplasia, also named Btrimorphic syndromeB (i.e. three (inherited) morbidities, pulmonary, hepatic and cytopenia), is a rare disease reported in 4 cases to date, manifesting with idiopathic pulmonary fibrosis, hepatic nodular regenerative hyperplasia leading to portal hypertension and thrombocytopenia due to bone marrow hypoplasia. The condition was associated with 100% mortality.
Features include very common findings: Portal hypertension, Hepatosplenomegaly, Lung scarring (pulmonary fibrosis), and Bone marrow hypocellularity and others; and common findings: Low platelet count (thrombocytopenia), Restrictive ventilatory defect, Dyspnea, and Elevated circulating hepatic transaminase concentration and others. 16 total HPO annotations.
