Pulmonary hyalinising granulomas are rare, non-infectious, benign fibrosing lesions of the lung that can, sometimes, mimic pulmonary malignancy. Clinical presentation Most patients (~ 75% 6) with pulmonary hyalinising granulomas can be symptoma.. Pulmonary hyalinizing granuloma (PHG) is a benign and rare lung disease. It was first described by Benfield et al. in a 51-year-old female with retroperitoneal fibrosis and bilateral pulmonary granulomas [ 1 ]. It can present as single or multiple lung nodules. Most of the lesions are discovered incidentally as they are relatively asymptomatic Introduction Pulmonary hyalinizing granuloma (PHG), a rare benign tumorous lesion mimicking a pulmonary neoplasm, occurs as a single or multiple lesions with unilateral or bilateral lung involvement. A definite diagnosis certainly requires pathologic evaluations A cause, the most common being infection, can be established in many surgically resected pulmonary necrotizing granulomas that appear unexplained at the time of initial histologic diagnosis. Patients whose granulomas remain unexplained after a rigorous review have a favorable outcome

Pulmonary hyalinizing granuloma (PHG) is a rare benign lung disease characterized by fibrosing nodules, Microscopically, the lesions are well-circumscribed and are characterized by a dense network of concentric hyalinized collagen in the center of perivascular lymphoplasmacytic infiltrate that rarifies in the center of the nodule Granulomatosis with polyangiitis. This condition causes inflammation in your lungs and other parts of your body. It's a blood vessel disorder that slows down the flow of blood to your organs. Once.. One of the most common causes of lung granulomas is a type of fungal infection known as histoplasmosis. You can develop histoplasmosis by breathing in airborne spores of a fungus normally found in..

Pulmonary hyalinizing granuloma (PHG) is a rare disease characterized by hyalinized lamellar collagen bundles, usu- ally surrounded by plasma cells, lymphocytes, and histio- cytes (1) Amorphous, punctate, and reticular patterns of calcification have been described in lung cancer. Malignant tumors may engulf a pre-existing granuloma, or tumor necrosis can manifest as tumor dystrophic calcification. Calcification in a mucinous adenocarcinoma may occur as a primary phenomenon Pulmonary hyalinizing granuloma (PHG) is a rare benign disease that has been shown to be associated with the deposition of immune complexes in the lung parenchyma caused by infection or autoimmune diseases. There have been no reports of PHG in association with immunoglobulin A nephropathy (IgAN)

Wegener's granulomatosis is a form of vasculitis that classically affects the lungs, kidneys, and upper respiratory tract. It is the most common type of vasculitis seen in lung biopsies. Patients usually present with cough, hemoptysis, dyspnea, renal failure, sinusitis, and/or epistaxis Pulmonary hyalinizing granuloma (PHG) is a rare, benign lung disease of unknown etiology. It usually manifests as solitary and sometimes as multiple pulmonary nodules. It may have irregular margins, cavitation, or calcifications mimicking metastasis or primary lung neoplasm. It should be considered in the differential diagnosis of pulmonary nodules or masses Rationale: Pulmonary hyalinizing granuloma (PHG) is a rare benign disease that has been shown to be associated with the deposition of immune complexes in the lung parenchyma caused by infection or autoimmune diseases. There have been no reports of PHG in association with immunoglobulin A nephropathy (IgAN).. Patient concerns: A 30-year-old woman visited with a 12-month history of dyspnea on. Pulmonary hyalinizing granulomas (PHGs) are rare nodular lung lesions with characteristic pathologic features: dense network of concentric hyalinized collagen lamella surrounded by perivascular lymphoplasmacytic infiltrate. Since 1977, when it was first described by Engleman et al., 1 fewer than 100 cases have been reported lung and another nodule at the right apex, highly suspicious for a neoplastic process. These were not present on a CXR from 2 years earlier. An 18fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) scan revealed that all lesions were strongly FDG-avid. Six CT-guided core-needle lung biopsy specimens were obtained from the lung mass and all contained dense.

Pulmonary hyalinizing granuloma with associated elevation

Pulmonary hyalinizing granuloma is an uncommon lung disease. Its etiopathogenesis is unknown, although it could be associated with an autoimmune or previous infectious process. The definitive diagnosis is provided by the histopathologic study of the lesion. although in the latter the stroma is made up of concentric hyalinized structures. A 48-year-old male was admitted to our hospital because of abnormal pulmonary shadows and a decrease in visual acuity. He had a history of tuberculosis 20 years ago. The chest roentgenogram showed multiple pulmonary nodules throughout both lung fields. No definitive diagnosis was established either by brushing cytology or biopsy through bronchoscopy or percutaneous needle biopsy Pulmonary hyalinizing granuloma (PHG) is a rare disease with distinct fibrosing lesions of the lung characterized by central whorled deposits of lamellar collagen. It has been reported that PHG is accompanied by extra-pulmonary fibrous lesions at various sites including the kidney, tonsils and thyroid glands. [1 visceral origin tumor but originated from the lung paren-chyma, which was protruding subpleurally and was con-nected to the normal lung with the stalk. Histopathologic examinations showed bundles of lamellar hyalinized col-lagen fiber and focal aggregation of lymphocytes, which were compatible with pulmonary hyalinizing granuloma (Figure 2)

Pulmonary Hyalinizing Granuloma: A Rare Cause of a Benign

An open lung biopsy revealed a mass in the upper A 34-year-old man without symptoms was referred to our segment of the lower lobe of the left lung and fibrous hospital to clarify an abnormal chest radiograph showing a exudate, which was adhered to the pleural surface. The nodular pulmonary lesion times partially or totally hyalinized. The granulomas are rounded and made up of histiocytes, fibroblasts, and some lymphocytes andplasma cells. Themajority of the histiocytes have within their cytoplasm the same material seen in the macrophages. All transitions were seen between these granulomatous foci and the nodular, well-defined scars made. Hyalinizing clear cell carcinoma of the bronchial glands is a very rare tumor. Since only five reports describing six tumors have been published to date, only a little is known about specific. The mixed population of plasma cells, lymphocytes and spindle cells with areas of hyalinized stroma (Images 4 and 5) and even direct invasion of a vessel and a bronchi (Images 7 and 8) could represent a pseudotumor, also called plasma cell granuloma in the lung (1, 2). The combination of necrosis with vessel involvement or hyalinized stroma.

and non-necrotizing granulomas with focal peribronchiolar hyaline fibrosis (Figure 3). Right paratracheal lymph node which was also excised showed anthracotic lymph node with hyalinized granulomas. Acid fast bacilli cultures and fungal culture which were taken intraoperatively were negative. Patient had negative ANA and ANC The lung gets trapped in that adhesion. Asbestos exposure can be the cause of hyalinized plaque. Radiologically, the folded lung shows airways leading into it, with a vaguely radial configuration that has been described as the comet tail sign. If the adhesion is removed surgically, the lung can reexpand and the nodule disappears Pulmonary Hyalinizing granuloma (PHG) is a rare form of lung pathology, often initially presenting as nodules prompting workup for possible malignancy. We present a case of a 29-year-old man with an irregularly shaped, described as a hyalinized spindle cell proliferation of mesenchymal origin with chronic inflammation, but no definitive. Pulmonary hyalinizing granuloma shows more lamellar hyalinized collagen than is seen in classical IPT. Hyalinizing granulomas of the lung are commonly multiple, whereas usual IPT is not. 77 Sclerosing hemangiomas 78 were once considered to be related to IPTs,.

A review of 76 cases of granulomatous inflammatory disease in the mediastinum shows the importance of fully characterizing granulomas, even when identified as sarcoidosis, to prevent misdiagnosis The septa that limit these sheets are partly infiltrated with lymphocytes, plasma cells, and fibroblasts and are partially transformed into fibrous bands, some- times partially or totally hyalinized. The granulomas are rounded and made up of histiocytes, fibroblasts, and some lymphocytes and plasma cells Granulomatous diseases are the heterogeneous group of the conditions of different etiologies with a variety of clinic syndromes and morphological features and nonuniform sensitivity to therapy, and the existence of granulomas as general dominate histological expression. Granuloma is indicative of chronic inflammation involving cells of the macrophage system and other inflammatory cells

Clinical, pathologic, and laboratory data from 62 patients with Histoplasma granulomas were available for review. Of these, 1 of 19 (5%) fungal cultures, 4 of 12 (33%) fungal serologic studies, 0 of 9 Histoplasma urinary antigen tests, and 0 of 2 Histoplasma serum antigen tests were positive. All but 3 of the Histoplasma granulomas were either in the resolving (grade 2) or resolved (grade 3. But the reported cases of pulmonary parenchymal involvement are rare and have almost consisted of hyalinized granuloma adjacent to a bronchus. We report a patient with Castleman's disease of the lung, pathologically proven interstitial pulmonary involvement Pulse granuloma is a rare benign entity that has also been called oral vegetable granuloma1 and giant cell hyaline angiopathy.2 Most of the literature suggests that the pathogenesis is a foreign body reaction to ingested legume parenchymatous cells at various stages of digestion. 1,3-7 Vegetable particles have been demonstrated associated with granulomas and hyaline rings in most of the. showed multifocal radiotracer uptake including within right lung mass, multiple bones, lymph nodes, liver and spleen.

Lung specimens revealed a non-necrotizing granulomatous pulmonary vasculitis described above, which mimicked a pulmonary malignancy on PET scan. Giant cell arteritis is a condition characterized by involvement of the temporal arteries, cranial arteries, or other carotid system arteries Pulmonary granulomas are a common finding in routine diagnostic pathology. However, these lesions are often problematic because of the broad differential diagnosis, the time required for identifying organisms and the need for familiarity with subtle variations in morphology and distribution of granulomas. This review aims to discuss the differential diagnosis, to compare and contrast the. Lungs were clear to auscultation bilaterally. Abdominal exam was normal except for mild tenderness upon palpation in all quadrants, but no masses, organomegaly, rigidity, or rebound tenderness were present.
