Mixed squamous cell and glandular papilloma of the lung is an extremely rare benign epithelial tumor showing a mixture of squamous and glandular epithelium. Here, we report a case of mixed squamous cell and glandular papilloma that presented as a solitary nodule in the left lower lobe of a 64-year-old woman. Chest computed tomography demonstrated a lobulated mass in the basal segment of the left lower lobe. The patient underwent a lobectomy under the suspicion of lung malignancy. The histopathological diagnosis was mixed squamous cell and glandular papilloma.

Pilomatricoma is a well defind and characteristic entity histologically, but this tumor may be encountered during aspiration biopsy of subcutaneous mass, and is, occasionally, confused with other neoplasms, particularly squamous cell carcinoma, basal cell carcinoma, and epidermal inclusion cyst. Recently, we have experienced a case of pilomatricoma diagnosed by aspiration biosy. The smear of the aspirate revealed anucleated "ghost" squamous cells, basaloid or basophilic squamous cells and nucleated squamous cells, which lack nuclear features of malignacy. These findings are consistent with pilomatricoma.

Osseointegrated implants are now commonplace in contemporary dentistry. However, a number of complications can occur around dental implants, including peri-implantitis, maxillary sinusitis, osteomyelitis, and neoplasms. There have been several reports of a malignant neoplasm occurring adjacent to a dental implant. In this report, we describe 2 such cases. One case was that of a 75-year-old man with no previous history of malignant disease who developed a solitary plasmacytoma around a dental implant in the left posterior mandible, and the other was that of a 43-year-old man who was diagnosed with squamous cell carcinoma adjacent to a dental implant in the right posterior mandible. Our experiences with these 2 cases suggest the possibility of a relationship between implant treatment and an inflammatory cofactor that might increase the risk of development of a malignant neoplasm.

A female unknown aged Yorkshire terrier, weighing 3.5 kg with nasal discharge, left facial swelling and severe inflammation was referred to Veterinary Medical Teaching Hospital, Seoul National University. Radiographic findings were lytic change and soft tissue swelling of left zygomatic process and increased radiopacity of nasal cavity. In computed tomography, turbinate bone destruction was observed as well as lytic change of left zygomatic process and left maxilla indicating aggressive lesion. Then 3-dimensional reconstruction was also performed. Biopsy of tissue mass revealed it as squamous cell carcinoma. For this patient, euthanasia was performed guarded prognosis. Generally, tumors of the nasal cavity in dogs account for approximately 1 % to 2% of all neoplasms. The prevalence of these tumors increased with age and exposure to the ultraviolet. About two thirds of all nasal tumors are malignant tumors such as squamous cell carcinoma and adenocarcinoma. As these tumors of nasal cavity are locally invasive, and external beam radiotherapy is the current treatment of choice. Unfortunately, diagnosis of these tumors often occurs late in the course of disease, resulting in a poor prognosis for outcome in many patients. It is considered that computed tomography could be used as an aid modality for the exact evaluation of extend and degree of bone lysis of nasal cavity and metastasis.

Growth factors and the receptors play an important role in the regulation of the growth and development of mammalian cells. In particular, epidermal growth factor is a polypeptide with potent mitogenic activity that stimulates proliferation of various normal and neoplastic cells through the interaction with its specific receptor(EGFR). EGFR has been described as a parameter of poor prognosis in many human neoplasms such as breast, bladder, and vulvar cancers. The objectives of this study are the evaluation of the expression of EGFR and cell cycle analysis in the head and neck squamous cell carcinomas(SCC), and the evaluation of the correlation between clinico-patholgic features and expression of EGFR and S-phase fraction. 37 head and neck squamous cell carcinoma specimens were evaluated for expression of EGFR by Western blot analysis and S-phase fraction by cell cycle analysis using the flow cytometry. The obtained results were as follows : 1. The expressions of EGFR were observed in 20 specimens(54%) among 37 head and neck SCC specimens. In case of oral SCC, 15 specimens(56%) out of 27 specimens were observed, and in case of nasopharyngeal SCC 5 specimens(50%) out of 10 specimens. 2. There was no correlation between clinical features(location, stage) of head and neck SCC and expression of EGFR (p>0.05). 3. There was a significant correlation between histo-pathological differentiation of head and neck SCC and expression of EGFR (p<0.02). 4. There was a significant correlation between expression of EGFR and S-phase fraction of cell cycle in the head and neck SCC (p<0.05). The above results suggest that expression of EGFR and S-phase fraction of cell cycle are adjunctive prognostic marker in the head and neck squamous cell carcinomas.

Squamous cell carcinoma infrequently occurs at the soft palate. Although various methods can be used for reconstruction of soft palate defects that occur after resecting squamous cell carcinoma, it is difficult to obtain satisfactory results from the perspective of the functional restoration of the soft palate. A combination of bilateral palatal mucomuscular flap for the oral side and superiorly based posterior pharyngeal flap for the nasal side were performed on two patients who were diagnosed with squamous cell carcinoma of the soft palate in order to reconstruct the soft palate defects after surgical resection. After surgery, the patients were followed-up for a mean period of 11 months. The flaps were well maintained in both patients. The donor site defects were epithelialized and completely recovered. Additionally, no recurrence of the primary sites was shown. Slight hyponasality was observed in the voice assessments that were conducted 6 months after surgery. No food regurgitation or aspiration was observed in the swallowing tests. We used a combination of bilateral palatal mucomuscular flap and superiorly based posterior pharyngeal flap to reconstruct the soft palate defects that occurred after resecting the squamous cell carcinomas. We reduced the donor site complications and achieved functionally satisfactory outcomes.

The coexistence of pneumothorax and pneumopericardium in patients with primary lung cancer is a very rare phenomenon. We report one such case, in which squamous cell carcinoma of the lung was complicated by pneumopericardium and pneumothorax. Several explanations of the mechanisms involved will be discussed.

Introduction: The characteristics of oral tongue squamous cell carcinomas (SCC) and the treatment results were reviewed to determine the appropriate treatment strategies. Materials and Methods: The medical records of 140 patients diagnosed and treated for oral tongue SCC at Yonsei University Health System from January 1995 to December 2004 were reviewed. For statistic analysis, the survival rate was determined using the Kaplan-Meier method with SPSS version 12.0, and the difference in survival rates was evaluated using a log-rank test. Results: The mean age of the patients with oral tongue SCC patients was 55 (19-85 years old). According to the T, N and pathologic stage, the patients were distributed from a higher to a lower incidence of cases, as follows: T2 (46.4%), T1 (37.9%), T4 (8.5%), and T3 (7.1%); N0 (65%), N1 (20.7%), N2 (13.6%), and N3 (0.7%); and stage I (31.4%), stage II(25.7%), stage IV (22.2%), and stage III (20.7%). Local and regional recurrence and distant metastasis was present in 13.6%, 5% and 4.2% of patients, respectively. The five-year survival rate was 72.2%, and the prognostic factors for oral tongue SCC included neck metastasis, pathologic stage of the disease, cell differentiation, treatment modality, neck dissection as part of the treatment plan, and neck node recurrence. Discussion: It is suggested that ipsilateral neck dissection or bilateral neck dissection should be selected as a treatment of tongue SCC patients with advanced stage.

Non small cell lung cancer (NSCLC) frequently metastasizes to brain, bone, liver, and adrenal glands. While an autopsy of NSCLC reveals some cases of metastasis to the kidney, clinical detection of renal metastases is extremely rare. Furthermore, metastases to the kidney usually present as multifocal or bilateral lesions and solitary renal metastases are usually suspected to be renal cell carcinoma. We now report a case of asymptomatic solitary renal metastasis from a primary squamous cell carcinoma, which was detected by routine surveillance with abdominal CT after curative surgery.
