Pulmonary capillary haemangiomatosis (PCH) is a rare vascular proliferative condition that can lead to pulmonary hypertension.Some authors consider it as a form of low-grade neoplasia 8, and it is still controversial if PCH and pulmonary veno-occlusive disease (PVOD) are varied expressions of the same condition or different entities.. It is characterized by multiple angiomatous lesions ...
Pulmonary capillary hemangiomatosis (PCH) is a rare disorder of alveolar capillary proliferation that clinically masquerades as idiopathic pulmonary arterial hypertension, or pulmonary venoocclusive disease (PVOD). The distinction of PCH or PVOD from idiopathic pulmonary arterial hypertension is important, because pulmonary vasodilators may be ...
Pulmonary capillary hemangiomatosis (PCH) is a rare and controversial entity that is known to be a cause of pulmonary hypertension and is microscopically characterized by proliferation of dilated capillary-sized channels along and in the alveolar walls. Clinically, it is mostly seen in adults. Clinical features are characterized by nonspecific ...
Pulmonary capillary hemangiomatosis (PCH) is a rare cause of pulmonary hypertension (PH) of unknown etiology resulting from pulmonary capillary proliferation. Clinically, PCH is seen in young adults with equal sex predilection and rarely reported familial predisposition. PCH's main clinical presentations are progressive dyspnea, fatigue ...
Pulmonary veno-occlusive disease/pulmonary capillary hemangiomatosis (PVOD/PCH) is a rare condition that represents a subgroup of patients with pulmonary hypertension . In general, PVOD progresses rapidly such that early recognition and treatment of this entity is critical.
Pulmonary capillary hemangiomatosis (PCH) is a disease affecting the blood vessels of the lungs, where abnormal capillary proliferation and venous fibrous intimal thickening result in progressive increase in vascular resistance. It is a rare cause of pulmonary hypertension, and occurs predominantly in young adults.
INTRODUCTION: Pulmonary capillary hemangiomatosis (PCH), a rare cause of pulmonary hypertension (PH), hypoxemia, and markedly impaired diffusion capacity of the lungs, is seldom identified antemortem. We report a case of early biopsy-proven PCH in a patient with rapidly progressive hypoxemia. CASE PRESENTATION: A 60-year-old female with a prior ...
Pulmonary capillary hemangiomatosis (PCH) is a pulmonary vascular disease that mainly affects small capillaries in the lung, and is often misdiagnosed as pulmonary arterial hypertension or pulmonary veno-occlusive disease due to similarities in their clinical presentations, prognosis, and management.

Pulmonary capillary hemangiomatosis (PCH) is an extremely rare cause of severe pulmonary hypertension. It is histologically defined by a proliferation of multiple layers of capillaries that expand alveolar septae, and often invade bronchial walls and pleura. The etiology of PCH is currently unknown. Using markers found to be abnormal in samples of the plexiform lesions from patients with ...
Pulmonary capillary hemangiomatosis or pulmonary microvasculopathy is a condition characterized by patchy overgrowth of alveolar walls, air spaces, and perivascular and peribronchial interstitium by capillary-sized vessels [200]. Subtle cases may only demonstrate alveolar septae with an increased capillary density. There are repeated episodes ...
Pulmonary capillary hemangiomatosis (PCH) is a rare pulmonary disease characterized by pulmonary hypertension and multifocal patchy areas of exuberant capillary proliferation in alveolar septa, pulmonary interstitium, and pleura. PCH was first recognized by Wagenvoort and colleagues in 1978. It is considered an idiopathic entity; however, it is ...
A 41-year-old man with idiopathic interstitial pneumonia (A) and PH was admitted because of worsening dyspnea on exertion. A diagnosis of exacerbating heart failure secondary to PH (B, C) was made because of pulmonary congestion, elevated BNP (1630 pg/mL) and elevated mean pulmonary artery pressure (50 mmHg).
pulmonary capillary hemangiomatosis (PCH) Category 1 pulmonary hypertension due to a second case of pulmonary capillary hemangiomatosis. Gross description. Multiple, red-brown, ill defined, nodular lesions Congested, edematous, without significant fibrosis Gross images.
Pulmonary capillary hemangiomatosis (PCH) is a rare and refractory capillary proliferation within the alveolar septae. This disease is characterized by a progressive clinical course with signs and symptoms of hypoxemia, alveolar hemorrhage, right heart failure, and pulmonary hypertension [1, 2].PCH has been described in patients ages 2 to 71 years [].
Pulmonary capillary haemangiomatosis (PCH) is a rare and incompletely understood histopathological finding characterised by abnormal capillary proliferation within the alveolar interstitium, which has long been noted to share many overlapping features with pulmonary veno-occlusive disease (PVOD). But are PCH and PVOD distinct entities that occur in isolation, or are they closely intertwined ...
Pulmonary capillary hemangiomatosis (PCH) is a form of pulmonary arterial hypertension (PAH) characterized by pulmonary capillary duplication and proliferation and a rapidly progressive, often fatal clinical course. Alveolar capillaries can invade the pulmonary interstitium, pulmonary veins and arteries, alveolar walls and septae, and other ...
INTRODUCTION: Pulmonary capillary hemangiomatosis is a locally aggressive benign vascular neoplasm of lung characterized by cytologically benign thin walled capillary-sized blood vessels proliferating diffusely through the pulmonary interstitium in and around airways and pulmonary vessels. It is a rare disease characterized by pulmonary hypertension and a slowly progressive clinical course ...
Pulmonary capillary hemangiomatosis is important to recognize because prostacyclin therapy, a mainstay in the treatment of pulmonary hypertension, has been reported to cause sudden respiratory distress and death in these patients. Prognosis of this disease remains poor, and the only definitive treatment is lung transplantation. ...
Protein Serine-Threonine Kinases. This article provides an overview of pulmonary veno-occlusive disease (PVOD) and pulmonary capillary hemangiomatosis (PCH), two disorders that challenge clinicians, radiologists, and pathologists because they often mimic pulmonary arterial hypertension (PAH). The article reviews the features that di ….

PURPOSE: Pulmonary capillary hemangiomatosis (PCH) is a rare capillary proliferation disease in alveolar septal, causes pulmonary artery hypertension.(PAH) We reviewed PCH diagnosed after lung transplantation in a systemic sclerosis with PAH patient.
