Thymolipomas are rare tumours located in the anterior mediastinum. Sometimes these tumours may be combined with thymomas or lymphomas. We present a unique case of a thymic carcinoid arising within a thymolipoma. A 68-year-old patient presented with chronic chest and neck pain, which was initially thought to be caused by coronary artery disease. A chest x-ray, exercise tolerance test and coronary angiography were unremarkable. The following CT scan of the neck and chest showed a small tumour in the anterior mediastinum. A robotic-assisted thymectomy was performed and histological examination revealed a neuroendocrine tumour of the thymus within a thymolipoma. The patient was discharged 3 days after surgery in good general condition.

Background: The study evaluated the safety and adequacy of percutaneous transsternal anterior mediastinal core biopsy.
Methods: All percutaneous computed tomography-guided transsternal mediastinal 18-gauge core biopsies performed at 2 academic centers were retrospectively reviewed. Procedural, clinical, and pathology data were recorded.

Background And Objectives: Atypical thymic carcinoids (ATCs) are rare mediastinal malignancies that lack established treatment guidelines. Capecitabine and temozolomide (CapTem) has demonstrated significant efficacy in pancreatic neuroendocrine neoplasms (NENs), while its applicability and effectiveness in ATCs remain underexplored. This study seeks to investigate the efficacy, safety, and prognostic factors associated with CapTem in ATC patients.

Neuroendocrine neoplasms of the thymus (tNENs), including typical carcinoid, atypical carcinoid, large cell neuroendocrine carcinoma, and small cell carcinoma, are rare tumors with scarce clinical and pathological data available in the literature. They share many common features with neuroendocrine neoplasms in other organs, such as those in the lungs, while demonstrating some distinct clinical and pathological features. This review aims to give an updated overview of each category of tNENs, focusing primarily on the pathologic diagnosis and differential diagnosis of these tumors.

Insulinoma-associated protein 1 (INSM1) immunohistochemistry has been established as a sensitive and reliable immunohistochemical marker for detecting neuroendocrine differentiation in tumors across various organ systems. However, this marker has not been adequately investigated in primary thymic neuroendocrine tumors. We have studied a series of 27 cases of primary neuroendocrine carcinomas of the thymus, including 3 typical carcinoids, 18 atypical carcinoids, 4 large cell neuroendocrine carcinomas, and 2 small cell carcinomas.
