        Fibromatoses are benign fibroblastic proliferation, which forms infiltrating tumor-like mass. Their histologic features cannot reflect the biologic behavior; local recurrence and aggressive infiltration to the adjacent tissue make fibromatoses intermediate tumor, between benign and malignant. Infantile fibromatosis consists of desmoid-type tumor and lipofibromatosis, and mainly affects children under age of 10. While desmoid-type tumor is characterized by elongated mature fibroblastic proliferation, the fibroblasts in lipofibromatosis look more primitive and accompany adipocytes. Here, we report a case of infantile fibromatosis of 4 month old boy involving the tongue.

        As the designated name, adenocarcinoma, not otherwise specific (ANOS) revealed lack of histomorphologic characteristics that could classify the tumors under specific name. ANOS had nothing in common with other salivary gland malignancies, but glandular differentiation. The purpose of this study is to find out the solid characteristics of ANOS on the base of cytological and architectural features. 20 ANOS cases were studied. We identified 20 patients with salivary adenocarcinoma, not otherwise specified, ranging in age from 26 to 76 years (median, 53.85 years), with slight female predilection (female 11: male 9). The minor salivary gland was the most common site of tumor origin, especially on the palatal area (11 out of 20). The size of tumor was from 1.0 to 7.0(median 3.07). For the histopathological analysis, we classified the tumors by cytological and architecture patterns. Basaloid and epitheloid cytological patterns were showed with solid, microcystic/pseudocystic architecture. We found invasive growth patterns in 7 out of 20 cases. Reviewing and classifying the common features of ANOS could be helpful to make a diagnosis of malignant salivary gland tumors.

        Lysyl oxidase (LOX) family, the copper dependent amine oxidase, oxidizes lysine residues in extracellular collagen and elastin. LOX increases the strength of the extracellular matrix and plays an important role in tumor development and metastasis. It has been reported that increased LOX protein and RNA are found in head and neck squamous cell carcinoma. Moreover some studies regarded LOX as a prognostic marker of oral and oropharyngeal squamous cell carcinoma. However there has not been any report on LOX expression of salivary gland tumors. Here, we investigated LOX expression in mucoepidermoid carcinoma (MEC) and adenoid cystic carcinoma (ACC) of salivary gland and compare it to those of pleomorphic adenoma (PA). We evaluated LOX expression in eighteen MEC, eighteen ACC and twenty PA cases by immunohistochemical examination. Whereas PA showed relatively low density of LOX expression, ACC revealed more cases that showing high staining intensities for LOX. Significantly increased LOX expression was found in the cases of ACC when compared to those of PA (P = 0.010).

        Clear cell odontogenic carcinoma (CCOC) is a very rare malignant neoplasm of jaw, with a significant clear cell component. It is nearly three times as common in the mandible with distinct female predominance. Past, identified as locally invasive tumor, CCOC is now considered to be malignant neoplasm, showing distant and regional lymph node metastasis. CCOC is histopathologically characterized by large glycogen-rich clear cells, often intermixed with eosinophilic cells. When diagnosing CCOC, ruling out salivary gland tumors, such as mucoepidermoid carcinoma or clear cell adenocarcinoma is important because they have overlapping histologic features with CCOC. Here in, we report a case of CCOC involving the right maxillary sinus of a 72-year-old female.

        Clear cell adenocarcinoma (CCA) is a rare malignant neoplasm of salivary gland that represents only 1% of all salivary gland tumors. CCA is histopathologically characterized by monotonous, glycogen-rich, round to ovoid clear cells intermixed with hyalinized stroma. However, other salivary gland tumors such as mucoepidermoid carcinoma, acinic cell adenocarcinoma, oncocytoma, epithelial-myoepithelial carcinoma, and myoepithelial carcinoma should be ruled out to diagnosis CCA. We herein report a case of CCA involving the soft palate in a 56-year-old female. It is essential to consider CCA in the differential diagnoses of clear cell tumors.
