<unk>  was also the name formerly (and incorrectly) used for a tumor now called a paraganglioma. A<unk>  (also known as a "solitary<unk> ," "solid<unk> ,") is a rare neoplasm arising from the<unk>  body and mainly found under the nail, on the fingertip or in the foot. They account for less than 2% of all soft tissue tumors. The majority of<unk> s are benign, but they can also show malignant features.<unk> s were first described by Hoyer in 1877 while the first complete clinical description was given by Masson in 1924. Histologically,<unk> s are made up of an afferent arteriole, anastomotic vessel, and collecting venule.<unk> s are modified smooth muscle cells that control the thermoregulatory function of dermal<unk>  bodies. As stated above, these lesions should not be confused with paragangliomas, which were formerly also called<unk> s in now-antiquated clinical usage.<unk> s do not arise from<unk>  cells, but paragangliomas do. Familial glomangiomas have been associated with a variety of deletions in the GLMN <unk> in) gene, and are inherited in an autosomal dominant manner, with incomplete penetrance.
