Mucosa-associated lymphoid tissue (MALT) lymphoma has specific clinical and pathologic features. The most common site MALT lymphomas is the stomach; however, it can also occur in other organs, such as the salivary glands. MALT lymphoma is rare, but its prognosis is good. A 32-year-old man visited Konyang university hospital with parotid mass. Superficial partial parotidectomy was performed to exclude lymphoid neoplasms. IgH gene rearrangement analysis of the surgical specimen led to the diagnosis of MALT lymphoma. The patient underwent esophagogastroduodenoscopy, positron emission tomography-computed tomography, and whole-body bone scan. Regional or distant metastasis was not observed on staging workup. The patient underwent postoperative radiation therapy, there has been no recurrence of MALT lymphoma to date. Here, we report this rare case of parotid MALT lymphoma that was treated with surgery and postoperative radiation therapy.

Clear cell odontogenic carcinoma (CCOC), a very rare neoplasm located mostly in the mandible, has been regarded as a benign tumor. However, due to the accumulation of case reports, CCOC has been reclassified as a malignant entity by the World Health Organization. Patients with CCOC present with regional swelling and periodontal indications with variable pain, often remaining misdiagnosed for a long period. CCOC has slow growth but aggressive behavior, requiring radical resection. Histologic analysis revealed the monophasic, biphasic, and ameloblastic types of CCOC with clear cells and a mixed combination of polygonal and palisading cells. At the molecular level, CCOC shows the expression of cytokeratin and epithelial membrane antigen, along with markers that assign CCOC to the sarcoma family. At the genetic level, Ewing sarcoma breakpoint region 1-activating transcription factor 1 fusion is regarded as the key feature for identification. Nevertheless, the scarcity of cases and dependence on histological data delay the development of an efficient therapy. Regarding the high recurrence rate and the potential of distant metastasis, further characterization of CCOC is necessary for an early and accurate diagnosis.

Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is a rare subtype of primary cutaneous lymphoma with a favorable prognosis. Primary cutaneous CD30+ lymphoproliferative disorders, which include C-ALCL and lymphomatoid papulosis, are the second most common group of cutaneous T-cell lymphomas. C-ALCL is comprised of large cells with anaplastic, pleomorphic, or immunoblastic cytomorphology, and indeed, more than 75% of the tumor cells express the CD30 antigen. C-ALCL clinically presents with solitary or localized reddish-brown nodules or tumors, and sometimes indurated papules, and they may be with ulceration covering with dark eschar. Multifocal lesions are seen in 20% of the patients. Extracutaneous dissemination, which mainly involves the regional lymph nodes, occurs in 10% of patients. A 69-year-old man noticed a mild elevated cutaneous lesion containing central ulceration covering with brownish black necrotic tissue on the right lower lip, and the lesion was surgically removed. After the first operation, another skin lesion was developed and the histological examination confirmed the diagnosis, C-ALCL. Eight specimens were excised during the 7-month follow-up period. The patient started the treatment with low-dose oral methotrexate (15 mg/wk) and there was no recurrence for 11 months.

The optimal treatments of carcinoma in situ of glottis include radiotherapy, laser surgery and vertical partial laryngectomy. Conventional surgical treatments need general anesthesia and radiotherapy has several complications. Recently, the effectiveness of 532 nm potassium titanyl phosphate (KTP) laser has been proven and widely used in vocal fold diseases even some cases of vocal fold dysplasia. A patient with difficult laryngeal exposure underwent fiberoptic laryngeal laser surgery using KTP laser under local anesthesia, showed improved voice outcome and the glottic lesion was removed successfully without local recurrence and regional metastasis 18 months after surgery.

Mucinous Eccrine carcinoma (MEC) is a rare malignant tumor related to the eccrine sweat gland and is commonly located on the face, especially around the eyelids and scalp. Most of these tumors are diagnosed at age 40's to 60's and exhibit a wide variety of patterns in addition to the general appearance previously reported. MEC is difficult to diagnose clinically, but can be diagnosed by accompanying biopsy. We present the case of a 75-year-old man who complained of a gradually growing Left lower lid tumor of duration one year. Initially, the tumor was mistaken for an epidermal cyst and treated by surgical resection. However, biopsy findings resulted in a diagnosis of Mucinous Eccrine carcinoma. Therefore, we performed wide excision and flap reconstruction surgery. In a one year follow-up examination, the patient achieved successful functional and aesthetic results without regional or distant metastasis and recurrence.

A 51-year-old male patient had four times of massive hematochezia episode three days before arrival. Carbohydrate antigen (CA) 19-9 level was extremely elevated. Computed tomography, magnetic resonance imaging, and positron emission tomography-computed tomography identified 5.7 cm sized periampullary duodenal cancer with regional metastatic lymph nodes and vascular invasion to aberrant right hepatic artery, main portal vein, and superior mesenteric vein. Diagnosed as duodenal adenocarcinoma through endoscopic biopsy, 16 times of FOLFIRI (5-fluorouracil, leucovorin, irinotecan) was conducted. The regimen changed to XELOX (capecitabine, oxaliplatine), four times of administration was done, and the CA19-9 level dramatically decreased. The tumor decreased to 2.1 cm. After R0 laparoscopic pylorus preserving pancreatoduodenectomy, no adjuvant therapy was given. No sign of recurrence or metastasis was reported, and the patient reached complete remission after five years. We reported a case where neoadjuvant chemotherapy for locally advanced duodenal adenocarcinoma was shown to be effective.

Purpose: To evaluate the prognostic value of preoperative neck lymph node (LN) assessment with $^{18}F$-fluorodeoxyglucose positron emission tomography ($^{18}F$-FDG PET), computed tomography (CT), and magnetic resonance imaging (MRI) in oral cavity squamous cell carcinoma (OSCC) patients with pathologically positive LN. Materials and Methods: In total, 47 OSCC patients with pathologically positive LN were retrospectively reviewed with preoperative $^{18}F$-FDG PET and CT/MRI. All patients underwent surgical resection, neck dissection and postoperative adjuvant radiotherapy and/or chemotherapy between March 2002 and October 2010. Histologic correlation was performed for findings of $^{18}F$-FDG PET and CT/MRI. Results: Thirty-six (76.6%) of 47 cases were correctly diagnosed with neck LN metastasis by $^{18}F$-FDG PET and 32 (68.1%) of 47 cases were correctly diagnosed by CT/MRI. Follow-up ranged from 20 to 114 months (median, 56 months). Clinically negative nodal status evaluated by $^{18}F$-FDG PET or CT/MRI revealed a trend toward better clinical outcomes in terms of overall survival, disease-free survival, local recurrence-free survival, regional nodal recurrence-free survival, and distant metastasis-free survival rates even though the trends were not statistically significant. However, there was no impact of neck node standardized uptake value ($SUV_{max}$) on clinical outcomes. Notably, $SUV_{max}$ showed significant correlation with tumor size in LN (p < 0.01, $R^2$ = 0.62). PET and CT/MRI status of LN also had significant correlation with the size of intranodal tumor deposit (p < 0.05, $R^2$ = 0.37 and p < 0.01, $R^2$ = 0.48, respectively). Conclusion: $^{18}F$-FDG PET and CT/MRI at the neck LNs might improve risk stratification in OSCC patients with pathologically positive neck LN in this study, even without significant prognostic value of $SUV_{max}$.
