Langerhans' cell histiocytosis of the thymus associated with multilocular thymic cyst

Human Pathology
P Wakely, Saul Suster


Though Langerhans' cells are a normal component of the thymus, the pathologic entity of Langerhans' cell histiocytosis (LCH) occurs very uncommonly in this organ. The few reports of thymic LCH are nearly all in children or young adults and may or may not be associated with extrathymic clinical disease. Although radiographic descriptions of cyst formation in the thymus in association with LCH have been reported, no examples to our knowledge of thymic LCH have been reported in association with multilocular thymic cyst (MTC). We report a case of thymic LCH in association with an asymptomatic multilocular thymic cyst which was discovered as part of cardiothoracic surgery in a middle-aged man. To our knowledge, this is the first example of MTC occurring in association with thymic LCH. HUM PATHOL 31:1532-1535.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
