Malignant tumors of the sinonasal tract constitute about 2% of those arising in the head and neck. Exposure to industrial fumes has been associated with an increased incidence of this malignant tumor. Early symptomatology of this cancer is identical to the symptomatology seen in benign conditions, such as swelling on forehead, headache, diplopia, and rhinorrhea. Thereby, delayed diagnosis leads to poor prognosis. Squamous cell carcinoma is the most common malignancy of the sinonasal tract, constituting about 80%, and primary carcinoma of the frontal sinus is extremely rare. Recently, authors experienced a case of primary carcinoma of the frontal sinus in a 60 year old male and performed transcranial resection. Now we report this case with brief review of literatures.

We report a case with squamous cell lung cancer with concomitant Guillain-Barre syndrome (GBS) as a paraneoplastic syndrome. A 67-year-old patient who was previously diagnosed as metastatic squamous cell lung cancer developed mild symmetrical weakness, paresthesia and sensory ataxia. Nerve conduction study showed sensorimotor polyneuropathy. Analysis of cerebrospinal fluid showed high tilter for monospecific anti-GD1b IgG antibody without onconeuronal antibodies. After treatment with intravenous immunoglobulin, the patient's symptoms improved.

Duplication of the urethra within a single penile shaft is a rare anomaly. These can be divided into those that are in the sagittal plane, which is most common, and those that occur side by side. In some cases, the accessory channel is complete, having a separate bladder opening and no communication with the more normal ventral urethra. In other cases, the accessory urethra is incomplete, either ending blindly or communicating with the urethra distal to the bladder neck. We report on a 20-year-old male with incomplete double urethra.

Primary intraosseous carcinoma(PIOC) is defined as a squamous cell carcinoma arising within the jaw, having no initial connection with the oral mucosa. The squamous cell carcinoma within the bone can be presumably developed from residues of the odontogenic epithelium, therefore, it is seen in the jaw only. Metastatic carcinoma from another primary site should be excluded in the diagnosis of Primary Intraosseous Carcinoma. This is a case of 62-year-old man, who initially diagnosed as odontogenic cyst on maxilla, but its pathologic examination was diagnosed as squamous cell carcinoma with odontogenic cyst. We treated this patient with partial maxillectomy, modified radical neck dissection(mRND), and postoperative radiation therapy.

Purpose: The cutaneous squamous cell carcinoma is the second most common skin malignancy. It is noted that keratoacanthoma is difficult to differentiate from squamous cell carcinoma, clinically or historically. It is still a hypothetical question whether keratoacanthoma is a pseudomalignancy or a form of squamous cell carcinoma. Methods: We report the case of squamous cell carcinoma around left ala of nose in a 64-year-old female patient. Through an incisional biopsy, the mass was found to be keratoacanthoma in the pathologic report. An excisional biopsy was performed. Results: Pathologic report notified that it was found well-differentiated squamous cell carcinoma arising in keratoacanthoma with focal involvement of deep resection margin. Wide excision was made with 0.5-1.5 cm margin and immediate reconstruction was performed. Conclusion: The relationship between keratoacanthoma and squamous cell carcinoma has been debated in the treatment. It is still controversial whether to excise it or not. We concluded that kerathoacanthoma must be removed completely.

The carcinoma of the maxillary sinus occupies about 0.25% of all human cancers. The radiations therapy for maxillary sinus hs not been practiced widely in this country. The authors treated a case of relatively advanced maxillary sinus cancer with combined radium and external irradiation with a succesful result. The clinical course and treatment are introduced and evaluated in detail. The authors believe that the carcinoma of the maxillary sinus is a curable disease even though it is relatively advanced one.

Mature cystic teratoma is a common ovarian lesion, approximately 10-20% of ovarian tumor. However, it can undergo a malignant transformation, but incidence of malignant transformation is very low. Squamous cell carcinoma is the most common type of malignant transformation in the mature cystic teratoma. Preoperative diagnosis of malignant transformation in the mature cystic teratoma is very difficult, because malignant transformed tissues are very small in the mature cystic teratoma components. And so most of the carcinoma arising in mature cystic teratoma were diagnosed after histologic examination. We experienced a case of squamous cell carcinoma arising in the mature cystic teratoma of the ovary and report a case with a brief review of the literatures.

Two cases of stomach mass and one case of tongue mass were observed in Japanese monkeys(Macaca fuscata) which were raised in Yong-in Farm Land. Histologically, two spontaneous tumors were found in the cardiac region of the stomach and were diagnosed as squamous cell carcinoma. These tumors had invaded the submucosa, muscular layer and serosa, but metastasis was not found in the other tissues including the lymph node. One spontaneous tongue mass was diagnosed as squamous cell carcinoma.

This is one case report of coexisting two histologically different carcinomas in the different lobes of the right lung, which operated the right pneumonectomy in the Dept. of Thoracic and Cardiovascular Surgery Hanyang University Hospital. The 43 years old male patient complained coughing, blood tinged sputum and weight loss. The chest films [PA and lateral view] showed a small round hazy shadow in the posterior segment of the right upper lobe and irregular hazy densities in the right middle lobe and hilar area. Histopathologically, the tumor in the posterior segment of the right upper lobe was consisted of a tissue of adenocarcinoma and the tumor in the right middle lobe was consisted of a tissue of well-differentiated bronchial squamous cell carcinoma.

Two 53-day-old broiler chickens were condemned due to multiple cutaneous nodular masses at slaughter house. Grossly, variable sized round masses were scattered in the abdomen and pelvis. Some of them were large and fused each other. Center of large fused nodules were ulcerated. Histopathologically, tumor masses consisted of multiple cords or masses of epidermal cells. Some of \ulcornerem contained central conoentric lamella of keratin (cancer pearl). From these results, these cases were diagnosed as cutaneous squamous cell carcinoma. This is the first report of cutaneous squamous cell carcinoma occurred in broiler chickens in Korea.
