Objective: To describe the radiological findings of long-standing pulmonary epithelioid hemangioendothelioma.
Materials And Methods: Serial radiography and CT, including high-resolution CT scans, were performed in two patients.
Results: The tumor has remained radiographically stationary for 10 and 20 years, respectively. On CT, both patients showed multiple calcified pulmonary nodules, up to 1 cm in size with a perivascular distribution. Interstitial involvement was seen in one case.
Conclusion: Calcification and perivascular location of the tumoral nodules were characteristic CT findings in our cases.

To shed light on the significance of thiazole derivatives in the advancement of cancer medication and to contribute to therapeutic innovation, we have designed the synthesis and antiproliferative activity investigation of 5-(1,3-dioxoisoindolin-2-yl)-7-(4-nitrophenyl)-2-thioxo-3,7-dihydro-2H-pyrano[2,3-d] thiazole-6-carbonitrile, the structure of thiazole derivative was confirmed by spectroscopic techniques UV, IR and NMR. The cytotoxic activity (in vitro) of the new hybrid synthesized compound on five human cancer cell lines; human liver hepatocellular carcinoma (HepG-2), colorectal carcinoma (HCT-116), breast adenocarcinoma (MCF-7), and epithelioid carcinoma (Hela), and a normal human lung fibroblast (WI-38) was studied using MTT assay. The compound exhibited a strong cytotoxicity effect against HepG-2 and MCF-7.

Malignant pleural mesothelioma (MPM) is a rare form of thoracic malignancy with a poor prognosis. Pleural effusion (PE) occurs in the majority of patients with MPM; however, its impact on MPM outcomes remains controversial. We searched for eligible patients from the Surveillance, Epidemiology, and End Results (SEER) database, and clinicopathological information and outcomes were collected.

Background/aim: Lymphangioleiomyomatosis (LAM) belongs to the perivascular epithelioid cell tumor (PEComa) family. The relationship between LAM and tuberous sclerosis complex (TSC) is of particular concern in a subset of women with clinically occult LAM involving the pelvic lymph nodes. This study aimed to investigate the clinicopathological features of incidental nodal LAM detected during the surgical staging of gynecological tumors.

Background: Epithelioid hemangioendothelioma (EHE) is an uncommon vascular malignancy characterized by an unpredictable clinical course and a high potential for recurrence and metastasis. The lack of standard treatment guidelines, coupled with the tumor's inconsistent response to available treatments, complicates the management of EHE and leads to widely varying patient prognoses.
Case Presentation: We report two cases of EHE with distinct presentations reflecting the site of involvement.

Granulomas, organized aggregates of immune cells which form in response to (), are characteristic but not exclusive of tuberculosis (TB). Despite existing investigations on TB granulomas, the determinants that differentiate host-protective granulomas from granulomas that contribute to TB pathogenesis are often disputed. Thus, the goal of this narrative review is to help clarify the existing literature on such determinants.
