Coexpression of intermediate‐sized filaments in sialadenoma papilliferum and other salivary gland neoplasms

Journal of Oral Pathology and Medicine (1990)

Akiyo Nakahata Hiroyo Deguchi Tetsuo Yanagawa Hideo Yoshida Mitsunobu Sato

The neoplastic cells present in a sialadenoma pappiliferum were found by immunoperoxidase method and immunofluorescent staining technique to co‐express 3 different types of intermediate‐sized filaments (IPs) defined by monoclonal antibodies to cytokeratin, vimentin and desmin. When other salivary gland tumors such as 18 pleomorphic adenomas, 15 adenolymphomas, 2 oxyphilic adenomas, 7 mucoepidermoid tumors, 5 acinic cell tumors, 8 adenoid cystic carcinomas and 6 adenocarcinomas were examined immunohistochemically for the expression of IPs, no tumors with all 3 types of IPs observed in sialadenoma papilliferum were found.

Four cases of cementifying fibroma.

Japanese Journal of Oral & Maxillofacial Surgery (1992)

Shinya Kawata Eiji Hayashi Youji Miyamoto Masaru Nagayama Hiroyo Deguchi

Cementifying fibroma is a relatively rare odontogenic tumor with a predilection for the jaw bone. We reported here 4 cases of cementifying fibroma we had recently encountered.The tumors of all 4 cases were surgically removed. Histopathological examination revealed that the tumorous lesions consisted of various amounts of fibrous tissues with extensive proliferation of cementum-like tissues.Therefore, the tumors were histopathologically diagnosed as cementifying fibromas. The prognosis of these cases are favorable with no sign of recurrence.

A case of transverse colon adenocarcinoma metastating to the maxilla and cervical lymph nodes

Japanese Journal of Oral & Maxillofacial Surgery (2007)

Naoya Kitamura Kousei Ishida Hiroyo Deguchi Tsuyoshi Hata Tetsuji Okamoto

Metastatic oral tumors generally carry a poor prognosis. It is therefore important to consider thepatient's quality of life (QOL) when planning treatment of metastatic oral lesions. In this article, we report a caseof transverse colon adenocarcinoma that metastasized to the maxilla and cervical lymph nodes 1 year after colorectomy.A 64-year-old man underwent surgery for transverse colon adenocarcinoma in January 2005 and received preoperativechemotherapy followed by secondary surgery because metastases to the iliopsoas muscle appeared in May2005. Because the patient's serum tumor marker levels increased again in October 2005 and he had swelling inhis left maxillary gingiva, he visited our hospital in January 2006. At presentation, the carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels were 18.1 and 689.9 ng/ml, respectively. Histologicalexamination of the gingival tumor revealed adenocarcinoma. Because distant metastasis was not detected in additionto the oral and neck lesions, we performed radical surgery of the oral and neck region. After surgery, theserum tumor marker levels of CEA and CA19-9 significantly decreased to 3.9 and 92.5 ng/ml, respectively. Thepatient is presently alive with no postoperative local recurrence or metastasis to other organs as of December 2006.

Intraosseous schwannoma of the mandible : A case report

Kawasaki medical journal (2009)

Satoshi Ito Toshiko Mandai Kosei Ishida Hiroyo Deguchi Tsuyoshi Hata

A 70‑year‑old man was referred to our department with the chief complaint of pain and swelling in the right posterior mandible. Panoramic radiography disclosed a large unilocular radiolucent lesion with distinct borders involving the right mandibular body and ramus extending from the second molar to the upper portion of the ramus. A complete excision was achieved by removing the tumor with the inferior alveolar nerve from the right mandible. Histologically Antoni‑A tissue was the predominant microscopic pattern but it occasionally alternated with Antoni‑B areas. Immunohistochemical staining for S‑100 proteins showed diffusely positive findings. An examination confirmed a diagnosis of an intraosseous schwannoma of the mandible.

Assessment of swallowing function following reconstruction of base of tongue and/or lateral pharyngeal wall with microvascular tissue transfer.

舌根, 中咽頭側壁欠損を遊離組織移植術で再建した18症例の術後嚥下機能を摂取食物形態, 水飲みテスト, Videofluorography により評価し, その再建術式を検討した。舌切除範囲は口腔舌を含め舌根1/2以上, 同側の舌骨上筋群, 口底が切除された。中咽頭側壁は舌切除または下顎枝切除に合併切除された。舌根1/2欠損10例は中咽頭側壁を合併切除しても前大腿皮弁や腹直筋皮弁再建により良好な嚥下機能が得られた。舌根2/3+中咽頭側壁欠損3例は前大腿皮弁で再建しても, 誤嚥が後遺した。舌が温存された中咽頭側壁欠損5例は残存粘膜の縫縮が可能な切除範囲でも遊離皮弁再建の方が術後嚥下機能は良好であった。術後嚥下機能は舌根切除範囲の拡大と共に低下した。その原因は再建舌根部の容積不足による口腔咽頭閉鎖不全と舌骨上筋群広範切除に伴う喉頭挙上障害と考えられた。今後, 再建術式の改良と誤嚥防止術の併施を図る必要がある。

A case of papillary adenocarcinoma arising on the left apex of the tongue.

Japanese Journal of Oral & Maxillofacial Surgery (1991)

Tetuo YANAGAWA Ryoji KAJI Takashi Bando Hitoshi Kawamata Yoshiaki Yura

A papillary adenocarcinoma with metastasis occurred in a 68-year old man. The neoplasma arose on the left apex of the tongue and metastasized to both neck lymph nodes. A partial glossectomy, marginal resection of the mandible and total neck dissection of both sides of the neck were performed. Histopathologic examination showed that the tumor was papillary adenocarcinoma, which invaded into deep muscle tissues and adjacent minor salivary glands but not in to the sublingual gland. In addition, metastatic papillary adenocarcinoma of 10 lymph nodes in the remaining 26 left cervical lymph nodes and 1 lymp node in the remaining 16 right cervical lymph nodes were observed.To clarify whether papillary adenocarcinoma of the tongue originated in the minor salivary gland or cc topic thyroid gland the immunohistochemical method was applied with the result that amylase (salivary type) was positive but thyroglobulin was negative. TI use results including clinical manifestation indicated that tumor originated in the minor salivary gland.
