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.

A case of squamous cell carcinoma of the thyroid gland associated with esophageal carcinoma is presented A squamous cell carcinoma of the thyroid gland is rare and is prognosis is poor. The histogenesis of squamous cell carcinoma is not clear, but at present, it is believed that most cases arise from the follicular epithelium It is very important to know whether squamous cell carcinoma of the thyroid is primary or secondary. Thus, the possibility of squamous cell carcinoma in the thyroid being the result of a metastasis or extension from a primary tumor in the trachea or esophagus must always be ruled out and intensive evaluation should be required to confirm the diagnosis of this disease. We report a squamous cell carcinoma of the thyroid associated with esophageal cancer with brief review of literature.

Squamous papilloma is a benign proliferation of stratified squamous epithelium, resulting in a papillary or verruciform mass. Verrucous carcinoma is a differentiated variant of squamous cell carcinoma and may present diagnostic difficulties as it may be erroneously diagnosed as squamous papilloma. Squamous papilloma is similar to other oral mucosa malignancy in microscopic view. So, it is difficult to distinguish between squamous cell papilloma and other oral mucosa malignancy. Here are three patients. they were diagnosed as squamous papilloma initially, but the lesion was recurred. In recurred lesion, verrucous carcinoma or squamous cell carcinoma were found. So we report that recurred oral mucosa malignency(verrucous carcinoma or squamous cell carcinoma) which was diagnosed as squamous papilloma.

Cutaneous squamous cell carcinoma has a high incidence. However, regional metastasis occurs infrequently because skin cancer is usually recognized and treated early. We report the case of squamous cell carcinoma around the earlobe in a 74-year-old male patient. The cutaneous squamous cell carcinoma invaded ipsilateral parotid gland directly without lymphatic spreading. Wide excision was made with 1.5 cm margin and immediate reconstruction was performed with radial forearm fasciocutaneous free flap. During operation facial nerve was preserved. No recurrence was noted for 5 years and the patient was satisfied with good aesthetic result. Cutaneous squamous cell carcinoma spreads to the parotid gland usually through lymph nodes and there are few reports of invasive organ damage by direct invasion. We experienced a case of direct invasion to parotid gland without lymph node involvement of cutaneous squamous cell carcinoma and treated the cancer adequately with wide excision and free flap coverage.

Background : Lung cancer is one of the most common malignancy in the world. Types of lung cancer are Non small cell lung cancer and small cell lung cancer. Subtypes of Non small cell lung cancer are adenocarcinoma, squamous cell carcinoma and large cell carcinoma. Knowing the type of lung cancer is important in determining both treatment and prognosis. Recently, due to newly developed anti-cancer drugs, squamous cell carcinoma has relatively poor prognosis than non-squamous cell carcinoma. Case : We report a squamous cell lung cancer case treated with allergen removed Rhus verniciflua Stokes (aRVS) extract. The patients initially diagnosed stage squamous cell lung carcinoma, but she refused recommended operation. She initiated aRVS extract monotherapy in October. 2006. The follow up Computed tomography in March. 2007, she diagnosed stable disease of tumor response on aRVS treatment. However, this case was lost to follow up for 6 months while she was treated with tomotherapy. In October 2007, she came back to our cancer center after diagnosed stage IV metastasized lung to lung, and aRVS monotherapy was restarted. She had survived 2 years after metastasis of squamous cell lung carcinoma. Conclusion : Allergen removed Rhus verniciflua Stokes(aRVS) sucessfully prolonged overall survival of a squamous cell lung cancer patient.

The oral cavity has frequent contacts with many carcinogenic compounds and its soft tissue is continuously stimulated by numerous dental factors. We have examined the detailed dental factors and its correlation with oral squamous cell carcinoma, and denture-wearing effects to analyze the effect of the dental factors on the genesis of oral squamous cell carcinoma. We have studied clinical contributing factors and the dental factors in the genesis of oral squamous cell carcinoma when the effects of smoking and drinking are controlled. The study cases are 100 patients(75 males and 25 females) who were diagnosed histo-pathologically as squamous cell carcinoma at the Yonsei Medical Center. The control group was 154 patients who have no systemic malignant tumors. The effects of 6 dental factors were analyzed in this study. They were divided into the smoking group, the non smoking group, the drinking group, and the non-smoking group. The effects of dental factors were analyzed in each group. In this study, we have drawn some conclusions on the relationship between the dental factors and oral squamous cell carcinoma using $x^2$-test. 1. The repaired teeth have statistical significance on the genesis of squamous cell carcinoma. This is probably due to the combining effects of past poor oral hygiene and continuous stimulation due to poor prosthesis. 2. There is statistical significance of the lost teeth in the smoking group, and the repaired teeth and the degree of alveolar bone resorption had statistical significance in the non-smoking group. 3. Smoking and drinking by-itself have no statistical significance in the genesis of oral squamous cell carcinoma. However, in combination, they have statistical significance. In this study, dental factors had a synergistic effect with smoking and drinking. Together with avoidance of smoking and drinking, appropriate restoration and oral hygiene control are most important factors in the preventive aspects of the oral squamous cell carcinoma.

A primary squamous cell carcinoma of the breast was evaluated by fine needle aspiration cytology in a 60 year-old female. Squamous cell carcinoma is a rarely encountered lesion in the breast and nine cases of cytologic findings of mammary squamous cell carcinoma have been reported in the world literature. Our case appears to be one of these rare pure squamous cell tumors. The cytologic diagnosis was possible because of the well defined characteristics of the malignant squamous cells, similar to those found in other locations. Thorough examination of the patient did not reveal squamous cell carcinoma elsewhere.

Distant metastasis of squamous cell carcinoma from the anal canal is an uncommon event. However, hematogenous spread to the vertebrae may occur in the course of this disease. The route of metastasis from the anal canal seems to be Batson's vertebral venous system. A 52-year-old female patient presented with lower back and right leg pain of one-week history. She has undergone radiotherapy and chemotherapy for squamous cell carcinoma of the anal canal and then was followed by surgical resection. Three months later, magnetic resonance images of the lumbar spine disclosed a well-enhanced mass of L5 vertebral body compressing the thecal sac. Surgical decompression and biopsy were performed. Histopathological study confirmed carcinoma of the squamous cell origin. We report a ra re case of vertebral metastasis from squamous cell carcinoma of the anal canal with a pertinent review of literature.

Primary intracranial squamous cell carcinoma is extremely rare, with most cases arising from a preexisting benign epidermoid cyst. We report a rare case of primary intracranial squamous cell carcinoma in the brain stem with a cerebellopontine angle (CPA) epidermoid cyst. A 72-year-old female suffered from progressive left hemiparesis, difficulty in swallowing, and right hemifacial numbness. Diffusion-weighted magnetic resonance imaging revealed a high signal intensity (SI) lesion in the CPA region and an intra-axially ring-enhanced cystic mass in the right brain stem with low SI. Whole-body positron emission tomography showed no evidence of metastatic disease. The histological findings revealed a typical epidermoid cyst in the CPA region and a squamous cell carcinoma in the brain stem. We speculate that the squamous cell carcinoma may have been developed due to a chronic inflammatory response by the adjacent epidermoid cyst. The patient underwent a surgical resection and radiotherapy. After 12 months, she had no evidence of recurrence.
