Rationale: This study aims to present a novel surgical approach for the resection of anterior mediastinal tumors, specifically focusing on micronodular thymoma with lymphoid stroma (MNT), a rare and distinct variant of thymoma. The single subxiphoid incision technique, although reported in limited cases, offers a minimally invasive option with potential benefits. We report the case of a 76-year-old male who underwent this innovative procedure and was diagnosed with MNT, providing insight into the management and outcomes of this rare pathology.

Rationale: Scapular prolapse is a rare complication of thoracotomy. Only a few cases of scapular prolapse after thoracotomy have been reported. Here, we report the case of a 52-year-old male patient who underwent standard posterior thoracotomy for lung sarcomatoid carcinoma invading the left upper chest wall.

The differential diagnosis and lesion location of CD and EAS often bring great difficulties to clinical diagnosis and treatment. This article reports the localization diagnosis, treatment, and follow-up results of two patients with ACTH-dependent CS with different causes and reviews the literature.

Its clinical diagnostic use, however, is not well studied. We retrospectively analyzed the data from 97 patients with suspected pulmonary cryptococcosis (PC) at 2 tertiary care centers.

By facilitating metabolite exchange or interfering with distinct signaling pathways, Cxs affect cell homeostasis, proliferation, and differentiation. Variations in the activity and expression of Cxs have been linked to numerous clinical conditions including carcinomas, cardiac disorders, and wound healing.

Especially primary pulmonary ENKTL is a relatively rare form of non-Hodgkin lymphoma. Until now, the prevalence of primary pulmonary ENKTL is unknown.

LINC00958 has been found involved in some cancers. However, the underlying mechanical performance of LINC00958 in lung adenocarcinoma (LAD) has not been explored yet.

The majority of adult primary tracheal tumors are malignant; however, as one type of benign tumors, lipoma is extremely uncommon. We report a case where lipoma was first misdiagnosed as bronchial asthma, followed by sudden aggravation of dyspnea after trauma, and computed tomography (CT) examination of the neck and chest confirmed a tracheal tumor. Through multiple bronchoscopy interventions and placements of a tracheal stent, little therapeutic benefit was discovered, and resection of the tracheal tumor combined with tracheal end-to-end anastomosis was performed to ultimately achieve a cure.

Case Presentation: We describe a case of an old female diagnosed with mid-oesophageal carcinoma, who presented with a TAF after oesophagectomy, which was healed by an effective treatment, while a severe TGCF and tracheostenosis appeared one month postoperation. The complications were detected by gastroscopy, barium oesophagogram and thoracic computed tomography (CT).
The vascular smooth muscle cell (VSMC) phenotypic switch is considered to be the key pathophysiological change in various cardiovascular diseases, such as aortic dissection, atherosclerosis, and hypertension. The results in this study showed that TGF-β1 promotes the proliferation, migration and morphological changes of VSMC.TGF-β1 promoted the expressions of PI3K, P-PI3K, AKT, P-AKT, ID2, and OPN protein and suppressed the expressions of α-SMA and SM22α protein; the opposite results were observed for TGF-β1 inhibitor group, AKT inhibitor group and Combined inhibitors group.
