Eponyms in the Dermatology Literature Linked to „bodies’’, Seen in Skin Biopsies

In dermatology practice, it is very common to hear about „Bodies’’, which refer to a pthological structure with a particular features. Most of them are large and can be seen by light microscopy, but there are few very tiny bodies which can only be seen by electron microscopy. Examples for the latter are comma-shaped body, and the worm-shaped body, seen in histiocytoses like benign cephalic histiocytosis (however; they are not specific), and zebra body, seen in mucopolysaccharidoses. Some of the bodies were seen in one disease and they are characteristic for one disease whereas others can be seen in multiple conditions. As an example for the former group, is caterpillar body, which is pale amorphous pink linear structures in the epidermis of porphyria cutanea tarda. Another example is the papillary mesenchymal body which is structure thought to be an abortive attempt of fibroblasts to form mesenchyme necessary for hair induction, reminiscent of early hair germ. They are seen in trichoblastoma and trichoepithelioma. Examples for the bodies which can be seen in multiple conditions include ,asteroid body for example might be seen in several conditions like sarcoidosis and berylliosis. Also, psammoma body is a concentric laminated, calcified bodies seen in papillary thyroid carcinoma, benign nevi, meningiomas, and other conditions. Most of the „bodies’’ are known by a single term. As an exception medlar bodies which are seen in chromoblastomycosis are also called sclerotic bodies and copper penny bodies. Eponyms are very common in the nomenclature of „bodies’’. In Table I [1-21], we are highlighting on Eponyms in the dermatology literature linked to „Bodies’’, seen in skin biopsies.
