AbstractAbstract PDF
Acinic cell carcinoma (ACC) is a rare, low-grade malignancy of the salivary glands. Most cases occur in the major salivary glands, especially the parotid gland, with only a few cases involving the minor salivary gland previously described. A 67-year-old male patient was admitted complaining of an obstructive feeling in the throat. On examination, a lobulated mass in the tonsillar surface was noticed. Tonsillectomy was performed under general anesthesia. Histopathological examination of the mass revealed sheets of large, polygonal acinar cells with granular, slightly basophilic cytoplasm, which led to the diagnosis of ACC. Here, we present a case of low-grade ACC of the palatine tonsil, which we believe to be the first reported case of ACC in this location.

AbstractAbstract PDF
True malignant mixed tumor (carcinosarcoma) of the salivary gland is an extremely rare tumor. By definition, it is a heterologous neoplasm that's composed of both malignant epithelial and mesenchymal components. We report here on a case of an 83 year old female patient with a parotid gland mass. Histologic examination showed a biphasic pattern of growth with both a poorly differentiated epithelial component and a sarcomatous spindle cell background. The immunohistochemical and ultrastructural findings support the diagnosis of a small cell neuroendocrine epithelial tumor and an undifferentiated malignant mesenchymal features. The histologic and ultrastructural features along with the immunohistochemical findings are presented. We also review the literature and we discuss the different opinions on the exact histogenesis of the true malignant mixed tumor of the salivary gland. To the best of our knowledge, this histological pattern has not been previously reported in the English medical literature.

AbstractAbstract PDF
Adrenocortical oncocytomas have rarely been reported on in the medical literature, and most of them have been nonfunctional and benign. We report here on a case of a 43-year-old man with a left abdominal mass. The patient showed no signs of hypertension or hormonal imbalance. The abdominal CT scans showed a huge mass that measured 11 cm in diameter, and it was located at the left adrenal area. Grossly, the tumor was well encapsulated and homogenous with central necrosis. Microscopically, the tumor was composed of oncocytes with abundant granular cytoplasm. Immunohistochemically, these cells were diffusely positive for cytokeratin and focally positive for synaptophysin and NSE. The ultrastructural studies showed numerous mitochondria in the cytoplasm. We will discuss the criteria that indicates malignancy as presented by Weiss et al. and we summarize the difference between conventional and oncocytic adrenocortical neoplasm. This case showed some features of malignancy based on the criteria presented by Weiss et al.

AbstractAbstract PDF
A case of Burkitt lymphoma diagnosed through fine needle aspiration cytology is described. A 66-year-old man presented with lymphadenopathy on the right cervical neck and axillary area. An ultrasonogram and CT scan for the cervical neck showed a multiple variable sized lymphadenopathy with pericapsular invasion and necrotic foci. Fine needle aspiration cytology (FNAC) of the cervical lymph nodes revealed very cellular and necrotic smears consisting of diffusely scattered intermediate monotonous round cells, tingible body macrophages and many mitotic figures. Histological features of the excised lymph nodes showed the classic morphological features of Burkitt lymphoma. Recognition of the characteristic cytological features can suggest the possibility of Burkitt lymphoma.

AbstractAbstract PDF
Although the genetic determinants of most sporadic breast cancers remain unknown, the understanding of the molecular and genetic events that contribute to breast carcinogenesis has been significantly advanced. We investigated the clinicopathologic significance of allelic imbalance or mutation of both p53 and PTEN tumor suppressor genes in sporadic breast carcinomas.
Genomic DNA from 62 breast carcinoma cases was extracted from paraffin blocks, and PCR was performed to determine loss of heterozygosity (LOH) for DNA markers around the p53 and PTEN genes and to amplify exons 5, 6, 7, and 8 of p53 and all 9 coding axons of PTEN.
Somatic p53 mutations were detected in 6 (9.7%) of the 62 cases. LOH for DNA markers surrounding p53 was observed in 18 (29.0%) of the 62 cases. LOH for DNA markers surrounding PTEN was detected in 29 (46.8%) of the 62 cases. Only one case (1.6%) showed somatic PTEN mutations. Tumors with LOH on 17p or p53 mutation were large in size and negative for ER, had a high Ki-67 index, and exhibited p53 immunoreactivity (p<0.05). Tumors with LOH on 10q23 were associated with c-erbB-2 positivity (p=0.018).
Our results indicate that LOH at 17p and/or p53 mutation is significantly associated with the aggressive pathologic parameters of breast cancer.

AbstractAbstract PDF
Paratesticular papillary serous tumors have been rarely reported, and they often resemble ovarian serous tumors of borderline malignancy. We experienced a case of papillary serous tumor in the left paratestis of a 39-year-old man. This is the second case reported in the Korean literature. The tumor, which was found incidentally during an operation for a hydrocele, was composed of papillary structures lined by cuboidal to columnar epithelial cells that displayed low cytologic atypia and frequent psammoma bodies.

AbstractAbstract PDF
Scleroma of the larynx is a rare specific granulomatous disease and is usually presented as alaryngeal extension of a primary rhinoscleroma. We report an unusual case of laryngeal scleromain a 64-year-old female patient whose presented with progressive upper respiratory obstructivesymptoms lasted for 2 years. Symptoms were acutely exaggerated during the course of one month.On physical examination, the nasal mucosa was atrophic and crusted, and septal perforationwas noted. The fiberoptic laryngoscopy revealed a yellowish granulated epiglottic mass with adirty surface mimicking laryngeal cancer. Histological sectioning showed the characteristic featuresof scleroma including Mikulicz cells with scattered plasma cells and some neutrophils.Warthin-starry stains and electron microscopy examination showed numerous short rods insidethe cytoplasm of the Mikulicz cells. After the diagnosis, the patient underwent an emergency tracheostomyfollowed by long-term antibiotic treatment, and her symptoms have slowly improved.
