Abstract
|
|
|
Glomus tumors are neoplasms that are composed of modified smooth muscle cells of the glomus body. Here, we report a case of multiple glomus tumors of the ankle that showed various histologic types, including the solid type (glomus tumor proper) and angiomatous type (glomangioma). The tumor cells observed in this case also showed prominent intranuclear inclusions, which has not yet been reported in glomus tumors. Ultrastructural examination demonstrated that the nuclear inclusions were not true inclusion bodies but were intranuclear cytoplasmic pseudoinclusions formed by cytoplasmic invaginations that formed as a result of the deep and complex nuclear contours.
