Abstract
PURPOSE To investigate the clinical and radiographic features of PNLH and the relationship with pathologic features. MATERIALS AND METHODS A total of 11 patients in whom PNLH was confirmed in our department were retrospectively studied. The clinical and radiographic features were extracted and analyzed, and we also discussed the relationship between radiologic and pathologic features. RESULTS Of the 11 patients with PNLH, 5 were discovered incidentally, while 4 presented with chest symptoms. Laboratory tests showed no specificity and the lesions were located under the pleura with an adjacent pleural indentation. Most lesions were solid, with some showing signs of spiculation or spiculate protuberance. In some cases, hypodense areas and vocules were visible. The enhanced scan showed marked enhancement, but most had no lymph node enlargement, and there was no pleural effusion. CONCLUSIONS The clinical manifestations of PNLH are nonspecific and the imaging features overlap with those of malignant lung tumors, and the diagnosis depends on pathologic examination.

Utilizing Immunoglobulin G4 Immunohistochemistry for Risk Stratification in Patients with Papillary Thyroid Carcinoma Associated with Hashimoto Thyroiditis. Endocrinol Metab (Seoul) 2024; 39:468-478.

Abstract
BACKGRUOUND Hashimoto thyroiditis (HT) is suspected to correlate with papillary thyroid carcinoma (PTC) development. While some HT cases exhibit histologic features of immunoglobulin G4 (IgG4)-related disease, the relationship of HT with PTC progression remains unestablished. METHODS This cross-sectional study included 426 adult patients with PTC (≥1 cm) undergoing thyroidectomy at an academic thyroid center. HT was identified based on its typical histologic features. IgG4 and IgG immunohistochemistry were performed. Wholeslide images of immunostained slides were digitalized. Positive plasma cells per 2 mm2 were counted using QuPath and a pre-trained deep learning model. The primary outcome was tumor structural recurrence post-surgery. RESULTS Among the 426 PTC patients, 79 were diagnosed with HT. With a 40% IgG4 positive/IgG plasma cell ratio as the threshold for diagnosing IgG4-related disease, a cutoff value of >150 IgG4 positive plasma cells per 2 mm2 was established. According to this criterion, 53% (43/79) of HT patients were classified as IgG4-related. The IgG4-related HT subgroup presented a more advanced cancer stage than the IgG4-non-related HT group (P=0.038). The median observation period was 109 months (range, 6 to 142). Initial assessment revealed 43 recurrence cases. Recurrence-free survival periods showed significant (P=0.023) differences, with patients with IgG4 non-related HT showing the longest period, followed by patients without HT and those with IgG4-related HT. CONCLUSION This study effectively stratified recurrence risk in PTC patients based on HT status and IgG4-related subtypes. These findings may contribute to better-informed treatment decisions and patient care strategies.

Abstract
Pulmonary nodular lymphoid hyperplasia (PNLH) is a rare non-neoplastic disorder, which can mimic malignancy due to its indolent yet progressive nature. Here, we report a case of surgically proven PNLH that progressed over many years from a ground glass opacity to a solid cavitating lesion mimicking a slow growing primary lung carcinoma.

Abstract
Pulmonary nodular lymphoid hyperplasia (PNLH) is a rare non-neoplastic disease that presents with mass lesions in the lung. It is radiologically difficult to differentiate it from adenocarcinoma of the lung or pulmonary lymphoma. There has been no consensus regarding the treatment of PNLH; however, in many case series, patients usually undergo surgical resection for diagnostic and therapeutic purposes. Here, we present the case of a 60-year-old Chinese male who presented with cough and hemoptysis. A computed tomography scan of the thorax revealed a mass-like lesion. A biopsy was performed which showed lymphocytic pneumonitis. He was treated with a tapering dose of corticosteroids with good clinical and radiological outcomes. Upon a subsequent review of the case, a diagnosis of PNLH was made. This case report suggests that corticosteroids may be an alternative therapy to surgical resection. They have the advantage of being non-invasive and can be used in patients who are otherwise not surgical candidates due to other comorbidities. However, further research is required before we can recommend corticosteroids as a treatment for PNLH.

Abstract
Pulmonary nodular lymphoid hyperplasia (PNLH) is a very rare disease, and it is difficult to diagnose PNLH and distinguish it from mucosa-associated lymphoid tissue (MALT) lymphoma. In addition, information on bronchoalveolar lavage fluid (BALF) analyses is lacking. We herein report a 36-year-old Japanese woman diagnosed with PLNH by a surgical biopsy and analysis of BALF. The BALF showed an increase in B-cell marker-positive lymphocytes, normal patterns of B-cell clonality, mucosa-associated lymphoid tissue 1 gene, and immunoglobulin heavy chain at 14q32 translocations. We also reviewed Japanese cases of PNLH described in Japanese or English to explore the characteristics of such cases.

Abstract
Pulmonary nodular lymphoid hyperplasia (PNLH) is a rare, benign lymphoproliferative disease, which is characterized by nonclonal lymphoproliferation. PNLH is usually asymptomatic and usually detected incidentally on imaging studies. Common imaging findings include a solitary nodule, multiple nodules, or focal consolidation. Atypically, PNLH may present with persistent subsolid nodules, mimicking adenocarcinoma. Here, we report a rare case of PNLH presenting as multifocal subsolid nodules in both lower lobes. During follow-up, persistency and growth of the subsolid nodules suggested the possibility of malignancy. Wedge resection was performed bilaterally, and PNLH was confirmed on pathological examination.

Abstract
Pulmonary nodular lymphoid hyperplasia is a rare, nonneoplastic lymphoproliferative disorder mostly manifesting as one or more nodules or localized lung infiltrates. The lesion comprises reactive germinal centers with well-preserved mantle zones and sheets of interfollicular mature plasma cells, lymphocytes, histiocytes, and neutrophils. The radiological finding is not specific, and the diagnosis of pulmonary nodular lymphoid hyperplasia relies generally on pathohistological and immunohistochemical analyses. The most important differential diagnoses are extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue and immunoglobulin G4–related sclerosing disease. Nonetheless, we present a case of pulmonary nodular lymphoid hyperplasia in a 69-year-old woman with the diagnostic challenge of cytological atypia in alveolar spaces inside the lymphoid tissue, coexisting with the diagnosis of adenocarcinoma of the lepidic pattern. Therefore, this case highlights the importance of identifying these rare benign and reactive lymphoproliferative diseases given the risk of developing not only lymphoma but also carcinoma.

Abstract
Background Pulmonary nodular lymphoid hyperplasia (PNLH) is a rare benign illness. Due to atypical clinical and radiographic presentations, diagnosis largely depends on postoperative pathological examination. Thus, preoperative misdiagnosis is often occurred. Case presentation We present a case of asymptomatic PNLH that was seen as ground-glass opacity (GGO) on computed tomography (CT). After 3-year observation, the diagnosis tends to adenocarcinoma owing to increasing density of the node and vessel convergence sign, which were signs of malignancy. Video-assisted segmentectomy (S10) was carried out. Histopathologic examination of postoperative specimen showed follicular lymphoid hyperplasia with interfollicular lymphoplasmacytosis, consistent with PNLH. The follow-up chest CT images showed no recurrence or metastasis. Conclusion Although it is a benign disease, PNLH can exhibit malignant signs in the imaging examinations, which could lead to misdiagnosis. This reminds us of the uncertainty between imaging findings and diagnosis. The diagnosis depends on postoperative pathological examination. Volume doubling time is a potential parameter to differentiate PNLH from lung cancer.
