Sir,

Shahi et al, refer to Langerhans cells and Langerhan [sic] cell in their report on testicular tuberculosis. [1] In reality, they mean to refer to Langhans' cells rather than Langerhans' cells. It is not uncommon to see this error being made by students as well as physicians writing in the learned journals and books. [2],[3]

Langerhans' cells are dendritic cells that are present in the epidermis. They were first described in 1868 by Paul Langerhans while still a student. [4],[5],[6] The multinucleate giant cells seen in tuberculosis, on the other hand, are named after Theodor Langhans who described them in the same year, 1868. Furthermore, both scientists published their seminal papers on these cells in the same journal, Virchow's Archives. [4],[5]

Another interesting fact is that both Langerhans and Langhans developed tuberculosis and this is consistent with the hypothesis that researchers may die or at least suffer from the same disease that they study! [7]

Both Langhans and Langerhans made other discoveries too-in 1869, Langerhans described the islets in the pancreas that now bear his name while Langhans in 1882 described a layer of cells in the cytotrophoblast. [4],[5] To my knowledge, there has been an eponymous mixup even between these cells: there exists an erroneous reference to Langerhans cells of the trophoblast! [8]

Finally, I have recently seen a histopathology report signed out with a diagnosis of Langhans cell histiocytosis!
