 Abstract

- An adenoid cystic carcinoma is a very rare primary pulmonary neoplasm. Bronchial washing and brushing cytological findings of pulmonary adenoid cystic carcinoma have rarely been described. Here, we report the bronchial brushing cytological findings of an adenoid cystic carcinoma, finally diagnosed in a 71-year-old female patient. The low-power view showed moderate cellularity and cohesive clusters of small to medium-sized cells. The high-power view revealed distinct nuclear moldings, a coarse chromatin pattern, and inconspicuous nucleoli, which was favorable to a diagnosis of small cell carcinoma. However, apoptotic bodies, nuclear debris, and mitoses were not seen frequently. The bronchial biopsy showed solid, trabecular, and cribriform patterns in small cells. Periodic acid Schiff staining disclosed globular basement membrane-like materials, and the immunohistochemical staining revealed the presence of myoepithelial cell components, strongly suggestive of a salivary gland type tumor, compatible with an adenoid cystic carcinoma. In this report, we describe the exfoliative cytological features of a pulmonary adenoid cystic carcinoma with emphasis on some diagnostic pitfalls.

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.

- BACKGROUND
A medulloblastoma is a primitive neuroepithelial tumor of the cerebellum that occurs in children and metastasizes through the cerebrospinal fluid. It is highly malignant and invasive, and the 5-year survival rate is only 60%. Surgical resection techniques, radiation, and chemotherapy have improved the overall survival but the patients suffer life-long cognitive dysfunctions or endocrine abnormalities as the side effects of treatment.
Therefore it is essential to identify prognostic markers to determine the appropriate treatment strategy in order to minimize the side effects.
METHODS
This study evaluated the immunohistochemical differentiation and survival rate with synaptophysin, glial fibrillary acidic protein, epithelial membrane antigen, vimentin and primitive neuroepithelial marker nestin of 55 paraffin-embedded medulloblastomas, using a tissue microarray. The expression of survivin, the apoptotic inhibitor, and the survival rate with regard to the proliferation index of Ki-67 were also investigated.
RESULTS
The group testing positive to vimentin, a mesenchymal differentiation marker, had a worse prognosis and there was a strong correlation between vimentin expression and nestin expression. Patients with a survivin expression rate >35% had a significantly poorer clinical course and there was a correlation between the survivin expression rate and Ki-67 expression rate.
CONCLUSION
In conclusion, vimentin and survivin are negative prognostic markers in medulloblastomas.
