Pathol Res Pract 2024; 260:155372. [PMID: 38878664 DOI: 10.1016/j.prp.2024.155372] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Revised: 05/21/2024] [Accepted: 05/27/2024] [Indexed: 08/09/2024]
Abstract
OBJECTIVE To explore the clinical, imaging, pathologic characteristics and differential diagnosis of solitary pulmonary capillary hemangioma (SPCH). METHODS Thirty two cases of SPCH were collected and studied, with literature review. RESULTS This study included 13 males and 19 females, with a male-to-female ratio of 1:1.5. The age ranged from 26 to 70 years (median age of 43 years). All patients were asymptomatic at presentation. Lung nodules were incidentally discovered during chest computed tomography (CT). Imaging features included 21 cases with partial solid nodules (PSN), 7 cases with ground-glass nodules (GGN), and 4 cases with solid nodules (SN). Eleven cases were in the left lung lower basal segment, 11 cases in the right lung lower basal segment, 6 cases in the right lung upper anterior segment, and 4 cases in the right lung middle lateral segment. The lower basal segments of the lungs were involved in 22 (11 in each lung) cases (22/32, 68 %). The tumors ranged from 6 to 18 mm (average 10 mm). Macroscopically, 16 cases had clear boundaries, while 16 cases had unclear boundaries, and gray-red or dark brown on cut surfaces. Intraoperative frozen section was performed in 27 cases, with diagnosis of SPCH in 12 and pneumonia or inflammatory lesion in 15. Microscopically, the nodules were composed of densely proliferated and dilated capillaries. The capillary walls were lined with a single layer of flat endothelial cells, without atypical features. Collapsed alveolar septa were replaced by a large number of capillaries. All cases showed proliferating capillaries spreading into the walls of small veins/arteries and bronchi, with 3 cases showing dilated capillaries protruding into the bronchiolar lumens as polyp-like structures. Twenty-six cases (26/32, 81 %) showed proliferating capillaries passed over the interlobular septa. Twenty-six cases (26/32, 81 %) showed irregular intimal thickening of small muscular arteries in the peripheral areas of the lesions, with the thickened intima being cellular or fibrous. In twenty-seven cases (27/32, 84 %) the lesions were located in the subpleura, with 6 cases involving the pleura. CONCLUSION SPCH is a rare benign lung tumor that mostly occurs in the lung lower basal segments with predominance in females. It usually appears as a ground-glass nodule on CT and is very similar to early-stage lung cancer. Accurate diagnosis requires collaboration of radiologists, surgeons, and pathologists. SPCH should be regarded as an important differential diagnosis of small incidental lung nodules.

Abstract
Pulmonary hemangiomas are benign, relatively rare tumours. Because computed tomography (CT) findings show a variety of images, it is often difficult to distinguish hemangiomas from lung cancer and other benign tumours. We report a 63-year-old man who was diagnosed with a pulmonary capillary hemangioma (PCH). A right lung basal segmentectomy was performed for diagnosis and treatment. On chest CT, the lesion was shown to be a solid nodule with contrast-enhanced margins. This finding was thought to reflect the dense vascular hyperplasia of the central part of the tumour based on the pathologic findings. Although few studies involving PCH have referred to contrast-enhanced CT, the findings of contrast-enhanced CT might be a valuable indicator for diagnosing PCH.

Solitary Pulmonary Capillary Hemangioma: CT and PET-CT Features with Clinicopathologic Correlation. Diagnostics (Basel) 2022; 12:diagnostics12112618. [DOI: 10.3390/diagnostics12112618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2022] [Revised: 10/26/2022] [Accepted: 10/26/2022] [Indexed: 11/17/2022] Open
Abstract
The aim of this study was to evaluate the CT and PET-CT features of solitary pulmonary capillary hemangioma (SPCH) with clinicopathologic correlations. This retrospective study included 17 patients with histologically proven SPCH from four tertiary institutions. The clinical, pathological and imaging findings of SPCH were reviewed. The CT features assessed included lesion location, size, density, contour, margin, enhancement, presence of air bronchogram, perivascular lucency and pleural retraction, and 18F-fluorodeoxyglucose uptake on PET-CT. Changes in the size during the follow-up period were also evaluated. Imaging features were correlated with the clinicopathologic findings. The mean age of the patients was 47 years (range 30–60 years). All SPCHs were incidentally detected during screening CT examinations (n = 13, 76%) or during cancer work-up (n = 4, 24%). Most SPCHs appeared as part-solid nodules (n = 15, 88%), the remaining appeared as a pure ground-glass nodule or a pure solid nodule, respectively. Most had smooth contours (n = 16, 94%), while one had a lobulated contour. Nine SPCHs (53%) showed ill-defined margins. Air bronchogram was present in ten (59%) SPCHs, and perivascular lucency in two (12%). All SPCHs exhibited hypoattenuation on contrast-enhanced CT and hypometabolism on PET-CT. During the follow-up period (mean 14.8 ± 17.7 months), the lesions showed no change in size or density in ten SPCHs (59%), decreased or fluctuation in size and density in three (18%). SPCH is often incidentally detected in young and middle-aged adults, commonly as an ill-defined part-solid nodule that may accompany air bronchogram, perivascular lucency, and fluctuation in size or density on CT and hypometabolism on PET-CT.

Abstract
Solitary pulmonary capillary hemangioma (SPCH) is a rare benign lung tumor. SPCH presents with a ground glass opacity on CT scan. Preoperative definitive diagnosis as SPCH is a real challenge. Immunohistochemical staining is essential for diagnosis as SPCH.
Introduction Solitary pulmonary capillary hemangioma (SPCH) is a rare benign lung tumor that clinically resembles early lung cancer and precancerous pulmonary lesions that present with similar imaging manifestations. Presentation of case The patient was a 54-year-old Japanese man who was referred to Nagara Medical Center with a ground glass opacity (GGO) lesion within the right upper lung that was incidentally detected on computed tomography. After 8 months of follow-up, video-assisted thoracoscopic segmental resection of the right upper lobe was performed with diagnostic and therapeutic intent. Pathologic examination of the resected specimen demonstrated thickening of the alveolar septum caused by the proliferation of capillary vessels. This lesion was positive for CD31 and CD34 and negative for thyroid transcription factor-1 and cytokeratin on immunohistochemical staining. The tumor was diagnosed as SPCH pathologically. Discussion When radiological examination demonstrates a GGO in the lung, SPCH must be considered as one of the differential diagnoses. For a definitive diagnosis, pathological examination of a surgically resected specimen must be conducted. Conclusion This study describes a case of SPCH and a review of the literature.

Abstract
BACKGROUND Solitary pulmonary capillary hemangioma (SPCH) is an extraordinarily rare capillary derived mesenchymal neoplasm. Although routine morphology and immunohistochemistry are adequate for the diagnosis of classical SPCH in surgical specimens, true gross appearance identification of most tumor themselves and diagnosis for some exceptional cases are still very difficult. Furthermore, preoperative imaging and frozen diagnosis remain a challenge. METHODS We reported nine original cases of solitary pulmonary capillary hemangioma and summarized the clinical characteristics of twenty-one reported lesions. Imaging materials were reviewed by the image experts of our hospital. Quick hematoxylin-eosin stained intraoperative frozen sections and routine histological diagnosis were re-confirmed by 3 specialist pathologists with at least 10 years of diagnostic experience in our department. Immunohistochemistry analysis was performed on formalin fixed archival tissue. The surgical methods, following up information and prognosis were retrospectively analyzed. RESULTS In imaging, three tumors showed solid nodules, three cases displayed mix ground glass nodules, two nodules were pure ground glass density, and one case was a cystic-solid mass. Macroscopically, solitary pulmonary capillary hemangiomas were ill-defined soft hemorrhagic lesion with pale yellow or dark brownish cut surface. Two cases had a clear boundary and seven lesions were poorly demarcated. Typical morphological features were densely proliferating thin-walled capillaries composing of single layer of flatten or cuboidal endothelial cells within the thickened alveolar septa. One case was mistaken for a histiocytogenic lesion during freezing. The cystic-solid lesion showed a hyperplasia capillary network along the submucosal interstitium of bronchioles. Immunohistochemically, tumor endothelial cells were positive for ERG, Fli-1, CD31, CD34 and Vimentin and negative for CK, α-SMA, TTF-1, HMB45, S-100 and CD68. Lobectomy was performed on seven cases, wedge resection and segmentectomy were proceeded in two patients respectively. Follow up information showed no evidence of complication or recurrence. CONCLUSIONS Solitary pulmonary capillary hemangioma has special imaging and various histological features and must be distinguished from small benign lung lesions and preinvasive cancer. Although the prognosis of this tumor is good after surgical resection, the correct interpretation of the gross appearance and radiographic findings are still important. Choosing appropriate resection mode depends on accurate evaluation preoperative and intraoperative.

Abstract
OBJECTIVES Solitary pulmonary capillary hemangioma (SPCH) is a rare lung tumor typically presenting as pure or part-solid ground-glass nodules (GGNs) on computed tomography (CT), which clinically resembles early lung cancer. MATERIALS AND METHODS In addition to 10 recently diagnosed patients with SPCH, 71 benign lung nodules that were surgically resected between January 2013 and December 2017 were reviewed by thoracic pathologists to identify any previously unrecognized SPCH cases. Finally, 6 tumors (8.5%; 6/71) were determined to be SPCH. Elastic fiber stain (orcein stain) as well as immunohistochemistry for cytokeratin, CD31, and thyroid transcription factor 1 were performed for confirmation. Clinical and radiological data were analyzed. RESULTS All 16 SPCH lesions were unrecognized or misdiagnosed by general pathologists. The SPCH ranged in size from 3 to 15 mm, and a predominance among women (68.8%; 11/16) was noted. Pathologically, all SPCH lesions were nodular with a higher vascular density than the adjacent lung tissue. Decreased cytokeratin staining and disrupted elastic fibers were clearly observed in all SPCH lesions. CONCLUSIONS SPCH lesions mimic early lung cancer on CT; they are largely unrecognized by general pathologists and are diagnosed as other nonspecific benign lesions. With careful histologic examination, SPCH can be successfully diagnosed using cytokeratin/CD31 immunohistochemistry and elastic fiber staining.

Abstract
Solitary pulmonary capillary hemangioma (SPCH) is a rare type of benign lung tumor, which must be distinguished from early lung cancer and precancerous lesions of the lung that manifest in a similar way upon imaging. The current study describes a case of SPCH and a review of the literature is performed. The patient was a 40-year-old Chinese woman who was referred to the Liaoning Cancer Hospital and Institute (Shenyang, China) in October, 2015 with a cough without obvious inducement. Computed tomography (CT) demonstrated pure ground glass opacity (GGO) in the right upper lung. Following systemic anti-inflammatory therapy over 6 months, the lesion did not exhibit any change on CT and was suspected to be an adenocarcinoma in situ (AIS) or atypical adenomatous hyperplasia (AAH). Video-assisted thoracic surgery wedge resection was subsequently performed. Frozen section diagnosis revealed a benign tumor without atypical epithelial cells. Subsequent to surgery, paraffin sections demonstrated that the tumor contained narrow alveolar cavities, thickened alveolar septa and a clear boundary separating it from healthy lung tissue. Furthermore, the proliferation lumens in the alveolar septa were lined with a single layer of flat cells. Immunohistochemical staining revealed that the flat cells were positive for cluster of differentiation CD31 and CD34, and negative for thyroid transcription factor-1 and cytokeratin. The proliferation of capillary vessels lead to the thickened alveolar septa and the tumor was diagnosed as SPCH. When imaging examination demonstrates a GGO in lung, SPCH must be considered in the differential diagnosis of AIS/AAH. As the prognosis of these lesions is entirely different, a pathological examination must be conducted to ensure a correct diagnosis.

Abstract
Background: Lung tumors are among the common tumors and can be benign or malignant. Benign lung tumors are less common compared to the malignant types. Recognition of the clinical symptoms, types of tumors, paraclinical findings, and treatment approaches can bring better therapeutic results. The present study aims to evaluate the characteristics, diagnosis methods, and therapeutic approaches of different benign lung tumors. Materials and Methods: In this retrospective study, 32 patients with a diagnosis of benign lung tumor, who had been referred to the Mashhad University of Medical Sciences between 1981 and 2009, were studied. Some of the studied variables were symptoms, the pulmonary location involved, surgery technique, pathology findings, recurrence, and surgery complications. Data were analyzed by SPSS package version 16. Results: The average age of the patients was 51.69 ± 20.5 years. Prevalence of benign lung tumors was equal in both genders. The most common symptom was cough (31.2%); right lung involvement was more common (71.9%), and the most common sampling technique was transbronchial lung biopsy (TBLB) (62.5%); 53.1% of the patients were operated on by thoracotomy and the wedge resection technique. In 78.1% of the patients, no complications occurred after surgery. There was no recurrence. Most operations were performed in one month after the start of the symptoms (68.8%). Conclusions: Benign lung tumors are commonly diagnosed by routine radiography because most of them are asymptomatic. The most common finding in radiography is the presence of mass in the lungs. Transbronchial lung biopsy is a valuable technique to be used for diagnosis. We chose thoracotomy and wedge resection for the treatment of patients. We recommend this approach as a useful method.
