 Abstract
- Malignant glomus tumor is a rare neoplasm arising from the glomus body, comprising categories of locally infiltrative glomus tumor, sarcoma arising in benign glomus tumor and de novo glomangiosarcoma. We report one case of locally infiltrative glomus tumor arising in nail bed of the right thumb of a 50 year-old woman. The tumor showed the architectural features of glomus tumor but cytologically bizarre, pleomorphic features without mitosis and infiltrative growth pattern to adjacent connective tissue and nerve. Immunohistochemical results were consistent with glomus tumor. This category of malignant glomus tumor must be distinguished from other round cell tumors because of its good prognosis.

- A case of sacrococcygeal chordoma diagnosed by fine needle aspiration is presented. This is a case of a 54-year-old woman who came with coccygeal pain of 5-6 months duration.
Aspiration biopsy cytology revealed many nests of cells having abundant bubbly cytoplasm and round to oval variably sized nuclei. The cells had indistinct cytoplasmic borders and many of the cells had cytoplasmic vacuoles. The nuclei had thin regular nuclear membranes, finely granular chromatin and one or two small nucleoli. The cells were generally monotonous, but focally pleomorphic with giant cell formation. Mitotic figures were scanty. The backgroud of the aspirate contained abundant mucinous materal. These findings were typical of those of recorded chordoma cases and the diagnosis was confirmed by a following open biopsy.
The patient received 4,000 rads of neutron radiotherapy and has been well till March '88.

Abstract
PDF
- Fine needle aspiration cytologic findings of four cases of chondrosarcoma were described. The cases consisted of one primary scapular tumor, two recurrent shoulder masses, and right upper quadrant mass which developed after an A-K amputation for an unknown tumor. The aspirates characteristically revealed cell-rich smears containing clusters and isolated cells having abundant cyanophilic cytoplasm and round to oval or elongated vesicular nuclei.
The cytoplasm was occasionally foamy. The nuclei were usually small but prominent. Nuclear atypism and pleomorphism were frequently associated. The last case showed epithelioid sheets of polygonal cells, possibly representing chondroblasts, and a well differentiated chondroid element. The fine needle aspiration could be a good diagnostic tool for primary, recurrent, and metastatic chondrosarcomas.
