Iotaderma #257
IOTADERMA #257 Plants are found frequently in dermatologic disease names: LICHEN planus, CHERRY and STRAWBERRY angiomas, POISON IVY dermatitis, an ASH LEAF macule in tuberous sclerosis, the LILAC ring of morphea, the peau d’ORANGE changes in inflammatory breast carcinoma, etc. In what disease is MOSSY foot used in a clinical description? Robert I. Rudolph, MD, FACP Answer will appear in the JAAD Online section of the August issue of the Journal.
JUNE IOTADERMA (#256) The word ‘‘sabre’’ is used in the description of the manifestations of 2 wellknown diseases in dermatology. The first usage is found in en coup de sabre, a variety of linear morphea usually located on the forehead or face. What is the other instance in which sabre has been used for decades to describe a striking clinical manifestation of an ancient disease? Answer: Sabre is used in ‘‘sabre shins,’’ one of the many osseous and dental deformities classically associated with late congenital syphilis.1 In affected patients, the tibiae are curved and bowed anteriorly when viewed from the side—hence the descriptive image of the sabre (which is a long, slightly curved, thick backed cavalry sword). This dramatic bony abnormality, interestingly, can also be found in several other disparate diseases, including yaws (a nonvenereal treponemal infection), severe vitamin D deficiency, or the rare WeismanneNetter syndrome.2 REFERENCES 1. Rasool MN, Govender S. The skeletal manifestations of congenital syphilis. A review of 197 cases. J Bone Joint Surg Br. 1989;71:752-755. 2. Khandare AL, Harikumar R, Sivakumar B.
