Background The frequencies of various causes of pulmonary granulomas in pathological material are unknown, as is the influence of geographical location on aetiology. The aim of this study was to identify the causes of pulmonary granulomas in pathological specimens, to define their frequencies, and to determine whether these causes vary by geographical location. Methods 500 lung biopsies and resections containing granulomas were reviewed retrospectively by expert pulmonary pathologists from 10… 

Lung granuloma: A clinicopathologic study of 158 cases

Mycobacterial TB and sarcoidosis are the most common causes of lung granulomas in the authors' region and in a substantial proportion of cases, the cause may not be identified despite an extensive workup.

Histopathology of Explanted Lungs From Patients With a Diagnosis of Pulmonary Sarcoidosis.

ESPS and UIP have distinct histopathologic features in the lungs and patients with a pretransplant diagnosis of sarcoidosis may develop other lung diseases that account for their end-stage fibrosis.

Clinicopathologic Features of Tissue Granulomas in Transplant Recipients: A Single Center Study in a Nontuberculosis Endemic Region.

Granulomas discovered pretransplant without clear infectious etiology likely do not require prolonged surveillance after transplantation and should be developed in a clinically judicious approach to their evaluation.

Subsequent Antituberculous Treatment May Not Be Mandatory Among Surgically Resected Culture-Negative Pulmonary Granulomas: A Retrospective Nationwide Multicenter Cohort Study

In patients with surgically resected culture-negative pulmonary granulomas, the incidence rate of subsequent active TB is low and watchful monitoring along with regular clinical, radiological, and microbiological follow-up, instead of routine anti-TB treatment, is a reasonable option.

Pulmonary necrotizing granulomas of unknown cause: clinical and pathologic analysis of 131 patients with completely resected nodules.

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.

Investigation of Granulomatous Inflammations in Terms of Tuberculosis Diagnosis: A 5-Year Multi-center Laboratory Study

Granulomatous inflammation showing “caseification necrosis” is considered pathognomonic for tuberculosis and the existence of a granulOMatous reaction should be considered first when examining a pathology report for the presence of tuberculosis.

Benign Solitary Pulmonary Necrotic Nodules: How Effectively Does Pathological Examination Explain the Cause?

A weak but significant correlation between granulomatous NNs and Bacillus positivity and a significant correlation around granulomas surrounding the NNs are found, which strongly support a diagnosis of tuberculosis, even in the absence of bacilli.

Etiological Distribution and Morphological Patterns of Granulomatous Pleurisy in a Tuberculosis-prevalent Country

It is suggested that most pleural granulomatous inflammation was attributable to TB-P in TB-endemic areas and that the granuloma patterns contributed little to the prediction of final diagnosis compared with other organs.

Diagnosis distribution in cases with granulomatous inflammation in lung, pleura, and lymph node biopsies: an experience from a tertiary level single center chest diseases and thoracic surgery hospital

The diagnosis of granulomatous inflammation detected in biopsy samples is common for clinicians and a differential diagnosis is difficult in many cases, but a final diagnosis only made following a multidisciplinary discussion is not a reliable finding.

Outcome of untreated lung nodules with histological but no microbiological evidence of tuberculosis

In patients having lung nodules with only histologic features suggestive of TB, the incidence rate of developing active TB was low and risk of adverse events and benefit from immediate treatment should be carefully considered.



Solitary necrotizing granulomas of the lung: Differentiating features and etiology

A prominent overlapping spectrum of histologic features was found between infectious granulomas and Wegener's granulomatosis, suggesting that the latter may represent an abnormal immune response to an infectious agent that is no longer identifiable within the tissue.

Incidence and nature of primary granulomatous inflammation in surgically removed material

Overall, the majority of the granulomas were due to five causes: sarcoidosis, mycobacterial infection, particulate inclusions, fungal infection, and rheumatoid arthritis.

Granulomatous lung disease: an approach to the differential diagnosis.

The differential diagnosis of granulomas in the lung is reviewed, a practical diagnostic approach is suggested, and major diagnostically useful histologic features are emphasized, including appropriate interpretation of special stains.

One Hundred Consecutive Granulomas in a Pulmonary Pathology Consultation Practice

The use of a standardized algorithmic approach to the interpretation of granulomatous disease in lung biopsies yields more specific and clinically useful diagnoses for consideration.

Surgical pathology of granulomatous interstitial pneumonia.

Agranulomatous interstitial pneumonia is a form of diffuse lung disease in which granulomas are a component of the histologic findings, and the pathologist's approach to these conditions can be facilitated by giving careful attention to the anatomic distribution of the granuloma, the qualitative features of thegranulomas, andThe histologic changes in the lung tissue around and away from the granULomas.

Study of surgically excised pulmonary granulomas.

Through application of Gomori's methenamine-silver nitrate stain to 138 surgically excised lesions over a two-and-a-half-year period, it was possible to identify "structures" resembling Histoplasma capsulatum or Coccidioides immitis in 55.9%.

Pathological diagnosis of granulomatous lung disease: a review

The main histological features that help distinguish various granulomatous lung diseases are summarized and helpful features in the differential diagnosis are emphasized.

Solitary necrotizing granulomas of the lung: differentiating features and etiology.

A prominent overlapping spectrum of histologic features was found between infectious granulomas and Wegener's granulomatosis, suggesting that the latter may represent an abnormal immune response to an infectious agent that is no longer identifiable within the tissue.
