Thymus is a bilobed organ usually situated in the superior mediastinum. Thymus is normally active until puberty and as age advances it undergoes considerable fibrofatty degeneration and is replaced by fatty tissue. We found a persistent thymus in an adult male cadaver aged 70 years approximately. It apparently looked healthy. Hence the objective of this study was to know the morpho-histology of...

Cervical thymic masses are congenital lesions that result from aberrant thymic migration during embryogenesis. Most of these masses are asymptomatic. Rarely cervical thymus becomes symptomatic with encroachment on adjacent aerodigestive structures. It should be considered in the differential diagnosis of neck masses, especially in children. Most cases are clinically misinterpreted as branchial ...

Ectopic intrathyroidal thymic tissue can form a mass lesion within the thyroid gland and has rarely been reported in children. We report a case of intrathyroidal thymus accompanied by an intrathyroidal parathyroid gland in a 29-year-old woman who visited our hospital due to right neck mass diagnosed as metastatic papillary carcinoma by aspiration cytology in an outside hospital. She had a histo...

Submandibular swellings occur relatively commonly in infants and children. Such swellings may be congenital or acquired. The differential diagnoses generally include common conditions, such as cervical lymphadenopathy, branchial arch anomalies, vascular malformations, inflammatory lesions and, less commonly, neoplasm.1-6 Biopsy or excision is the standard approach taken for most pediatric nonva...

Myasthenia gravis (MG) is associated with ectopic germinal centers in the thymus. Thymectomy and glucocorticoids are the main treatments but they induce operative risks and side effects, respectively. The aim of this study was to propose new therapies more efficient for MG. We hypothesized that molecules dysregulated in MG thymus and normalized by glucocorticoids may play a key role in thymic p...
