Lung cancer is one of high mortality malignancy. It is known that skin metastasis from lung cancer is uncommon. We report a very rare case of finger tip metastasis from double primary cancer of the lung and lower lip. A 79 year-old man diagnosed with non small cell lung cancer presented with protruding solid mass in his lower lip. It showed central necrosis with purulent discharge. It had appeared rapidly growing features. Simultaneously, another solid mass accompanying painful swelling without skin lesion was found in his left middle finger tip. Both two solid masses were moderately differentiated squamous cell carcinomas. Lower lip mass was a primary cancer, while middle finger tip mass was diagnosed with clinically metastatic cancer from lung or lower lip, which means that it had double primary cancer origin.

Lip and oral cavity cancer, which can occur in any part of the mouth, is the 11th most common type of cancer worldwide. The major obstacles to patients' survival are the poor prognosis, lack of specific biomarkers, and expensive therapeutic alternatives. This study aimed to identify the main genes and pathways associated with lip and oral cavity carcinoma using network analysis and to analyze its molecular mechanism and prognostic significance further. In this study, 472 genes causing lip and oral cavity carcinoma were retrieved from the DisGeNET database. A protein-protein interaction network was developed for network analysis using the STRING database. VEGFA, IL6, MAPK3, INS, TNF, MAPK8, MMP9, CXCL8, EGF, and PTGS2 were recognized as network hub genes using the maximum clique centrality algorithm available in cytoHubba, and nine potential drug candidates (ranibizumab, siltuximab, sulindac, pomalidomide, dexrazoxane, endostatin, pamidronic acid, cetuximab, and apricoxib) for lip and oral cavity cancer were identified from the DGIdb database. Gene enrichment analysis was also performed to identify the gene ontology categorization of cellular components, biological processes, molecular functions, and biological pathways. The genes identified in this study could furnish a new understanding of the underlying molecular mechanisms of carcinogenesis and provide more reliable biomarkers for early diagnosis, prognostication, and treatment of lip and oral cavity cancer.

Lymphocytic interstitial pneumonia(LIP) is characterized by a massive infiltration of the interstitium of the lung by mature lymphocytes, plasma cells and reticuloendothelial cells. LIP may be associated with autoimmune diseases including Sj$\check{o}$grens syndrome, SLE, myasthenia gravis, pernicious anemia, autoimmune hemolytic anemia, and HIV or an EB virus infection. There is a possibility of LIP progressing to a pulmonary or systemic lymphoma. The therapeutic response to corticosteroids and/or immunosuppressive drugs varies. Here we report a case of LIP that was diagnosed by an open lung biopsy and clonality study. The patient was a 36 year-old man without autoimmune disease or HIV infection. He was admitted as a result of severe hypoxemia showing $PaO_2$ of 48.3mmHg. The patient was treated with corticosteroids after the diagnosis and had fully recovered without a sequalae or relapse.

구강암의 발생 시, 구순의 결손과 방사선치료에 의한 치주조직과 치경부우식증 등의 문제가 발생할 수 있다. ADI (Association of dental implantology)에 의하면 상 하악골에 대한 방사선치료가 최근에 시행되었을 경우 임플란트를 식립하는 것은 상대적 비적응증이 된다. 대부분의 경우 임플란트를 이용한 보철물의 제작이 어렵고 의치를 사용한 수복이 이루어지게 된다. 특히, 구강암 수술로 인한 구순결손은 의치의 유지에 심각한 영향을 주게 된다. 본 증례는 상순암을 가진 환자로 일차적으로 절제술을 시행하고, 이차적으로 방사선 치료가 정기적으로 이루어진 결과, 환자의 상악 치아들은 순차적으로 자연 발치되었고, 하악은 매우 불량한 치주상태를 나타내었다. 상악은 총의치에 의치접착제를 적용하여 구순결손에 의한 의치의 유지력 저하를 극복하였고, 하악에서는friction pin을 이용한 하악이중관의치가 2년 동안 성공적으로 사용되었다.

Since the upper lip does not receive direct actinic radiation, only 5% of lip tumors develop in the upper lip, while the lower lip is the site of the remainder. Among the lower lip cancer, squamous cell carcinoma is the most common tumor, especially the vermillion border of lower lip is the most common site. The aims of reconstruction of the lip are both aesthetic effect and functional restoration and the ideal procedure must produce a aesthetically normal, not-tao-tight lip and a good sensation and muscle tone of the lip. We have a satisfactory reconstruction of a subtotal loss of lower lip after squamous cell carcinoma extirpation using Gillies fan flap and the case is presented with reviewing a many published reports.

Squamous cell carcinoma is the most common cancer occurring in the oral cavity and oncologic wide cancer excision is a major cause of large lip defects. Large lower lip defect reconstruction with good functional and aesthetic results has always presented a challenge for plastic surgeons. There are various lower lip reconstruction methods depending on its size, location, and surgeon's expertise. This is a case of a large defect spanning more than two-thirds of the lower lip after wide excision due to squamous cell carcinoma. The Karapandzic flap was used to reconstruct the defect with a commissuroplasty carried out in a second operation, which yielded a relatively good functional and aesthetic result. No recurrences or metastases were observed within a one year follow-up period.

The most common cause of treatment failure in oral cavity cancer is when it is found to have local recurrence, usually occurring in the ipsilateral cervical lymph node. On the contrary, it is extremely rare to find local recurrence in soft tissue metastasis (STM) in the contralateral neck. Furthermore, lung cancer and malignant lymphoma are most commonly confined to their primary sites. The poor general condition increases the likelihood of STM, which indicates bad prognosis. A 72-year-old man with a hard and fixed mass on the right submandibular space visited our clinic. He had received a wide excision with local flapreconstruction for squamous cell carcinoma in the left corner of lower lip 18 months ago. We performed the wide excision with bilateral selective neck dissection (I-III), and he was finally diagnosed as STM from contralateral lip cancer. We report this unique and rare disease entity with a literature review.

Generally, if the size of a lip cancer defect exceeds 30% of the lower lip, a local flap or free flap is recommended. However, defects up to 50% of the lower lip in size have been reconstructed successfully by primary closure without a local flap or free flap. In one case, an 80-year-old male farmer who had smoked for more than 50 years presented with squamous cell carcinoma of the lower lip and underwent mass resection and supraomohyoid neck dissection. The defect accounted for almost 2/3 of the lower lip and was repaired by primary closure with V-shaped resection. Biopsy results confirmed pT2N0cM0 stage II disease with clear margins. In another case, a 68-year-old male also presented with squamous cell carcinoma of the lower lip and underwent mass resection. The defect accounted for about half the size of the lower lip but was repaired by primary closure with V-shaped resection. Both patients experienced no discomfort while eating or speaking and were satisfied with the cosmetic and functional outcomes with no evidence of recurrence. Thus, direct closure can be considered even in large lower lip cancers.

This study aimed to investigate the correlation between ${\beta}$-catenin immunoexpression and histopathological grades of lower lip squamous cell carcinoma (LSCC). $\beta$-Catenin abnormal expression was found in 29% of the squamous cells of well differentiated LSCC, 63% of moderately differentiated and 86% of poorly differentiated, and therefor was significantly associated with histological grade (p=0.000). Nuclear $\beta$-catenin expression appeared in 5% of the cells and was also correlated with the histological grades (p=0.000). In 14.7% of the cells it was localized in the cytoplasm, again correlating with histology (p=0.002). According to this study the expression of $\beta$-catenin is an independent prognostic factor for histological grade and to the tumor differentiation. This appears to reflect a structural association and the role of $\beta$-catenin in tumor progression.

Squamous cell carcinoma of the lip is a common malignant tumor originating from oral cancer. However, unlike other areas, the lips hold significant functional and aesthetic importance as a part of the face. As a result, a tailored approach based on the tumor's size, type, and location is essential. The Karapandzic flap is especially suitable for reconstructing lesions located on the lip, particularly when the size of the cancer is large and other surgical treatments like free flaps are not feasible. It allows for extensive resection beyond the size of the lower lip. In this case, considering the patient's overall condition, successful reconstruction of the lower lip was achieved using the Karapandzic flap.
