Multiple Glomus Tumors of the Ankle with Prominent Intranuclear Pseudoinclusions.: Jae Yeon Seok, Se Hoon Kim, Tae jung Kwon, Jieun Kwon, Yoon Hee Lee, Kyoo Ho Shin, Woo Ick Yang; Korean J Pathol. 2007;41(5):337-342.

Abstract PDF: 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.

Phycomycosis Involving Ankle Joint: Report of a case.: Eui U Park, Jung Ran Kim, Je G Chi; Korean J Pathol. 1988;22(4):495-499.

Abstract PDF: Phycomycosis is an uncommon opportunistic fungal infection, involving several organs, such as brain, lungs, gastrointestinal tract and skin. Invasion of joint cavity by phycomycetes, however, has never been reported. We report a case of 33-year-old male who had had prehallux with congenital equinovarus and underwent correction operation on the right ankle joint. There after, joint pain and edema had developed on that site. He received reoperation and underwent excisional biopsy from there. Operation showed hypertrophied yellowish synovium. On microscopic examination, the tissue showed several foci of fibrinoid necrosis and suppurative and granulomatuous inflammation. Periodic acid Schiff stain demonstrated broad. Aseptate hyphae that were wrinkled and folded.

Congenital Melanocytic Schwannoma in Ankle Joint Potentially Malignant: A case report.: Jong Tae Park, Chang Soo Park, Sang Woo Juhng, Kyu Hyuk Cho; Korean J Pathol. 1987;21(4):308-316.

Abstract PDF: Congenital malignant melanocytic schwannoma in ankle joint was not reported on literature and it was a very interesting case. Light microscopically, melaninladen cells were mixed in abundant wavy spindle cells, some mitotic cells were also observed. Ultrastructurally, melanosomes in variable stages of development were scattered in the cytoplasm which had basal lamina. Collagen bundles were abundant in the intercellular connective tissue. It was histologically malignant tumor and clinically recurred. But in non-congenital potentially malignant melanocytic schwannoma which had been reported, reccurrence or distant metastasis were not noted. So, further clinical survey may be necessary for evaluation of the malignant behavior of this neoplasm.
