Tongue metastasis from carcinoma of the rectum

Primary intestinal-type adenocarcinoma of the tongue

Primary intestinal-type adenocarcinoma (ITAC) of the tongue is a rare neoplasm. The case of a 59-year-old male with a painless mass in the dorsum of the oral tongue diagnosed as primary ITAC is reported here. The particular characteristic of the case was the patient's long-term medical history of 40years. The patient underwent resection of the tongue carcinoma through a midline approach and direct suture, with postoperative chemoradiotherapy. Immunohistochemical staining indicated that the tumour was positive for CK20 and negative for CK7. A review of the English-language literature was performed, which identified six cases of primary ITAC and three cases of metastatic ITAC of the tongue. The clinical characteristics and therapeutic methods used in these cases were analysed.

Rectal adenocarcinoma metastatic to the tonsil; PET-CT observations with pathological confirmation: A case report

Metastasis of rectal adenocarcinoma develops by lymphatic or hematogenous spread. The usual sites of metastasis from rectal adenocarcinoma include local and distant lymph nodes, the liver and the lungs. The current case report presents a unique case of a mass that was identified in the tonsil by positron emission tomography-computed tomography (PET-CT), indicating a metastasis from rectal adenocarcinoma. Metastatic tumor to the tonsil is extremely rare and to the best of our knowledge, no previous studies have reported a case of tonsil metastasis from rectal adenocarcinoma. PET-CT scanners represent an important evolution in technology that is helping to bring anatomical imaging togeother with functional imaging in cancer diagnosis and therapy. Written informed consent was obtained from the patient.

Colonic-type adenocarcinoma of the base of the tongue: a case report of a rare neoplasm

Lingual adenocarcinomas (ADC), either primary or metastatic to the tongue are extraordinarily rare neoplasms. Primary lingual adenocarcinomas are primarily of minor salivary gland origin. Two cases of primary colonic-type adenocarcinomas of the base of the tongue were recently reported for the first time in the English literature. We present an additional case of lingual intestinal-type adenocarcinoma with mucinous features that occurred in association with cervical node metastasis and discuss the clinicopathologic features and histogenetic aspects of this rare entity.

Metastatic tumors to the oral and maxillofacial region: a retrospective study of 19 cases in West China and review of the Chinese and English literature

PURPOSE

The aim of this article was to obtain an overview of metastatic tumors to the oral and maxillofacial (OMF) region, especially the differences in the constituent ratios of primary cancers between the United States and China.

PATIENTS AND METHODS

Clinical findings of 19 cases encountered in West China Hospital of Stomatology were summarized and the English and Chinese literature were reviewed and analyzed. The main clinical features of OMF metastases were summarized, with an emphasis on primary cancers' constituents.

RESULTS

The lung, breast, kidney, liver, and prostate were the top 5 common primary sites of cancer. However, there was a significant difference in the primary cancers' constituents between United States and China (P < .001). The breast, kidney, prostate cancers, and melanoma of skin were more frequent primary cancers in United States than in China, whereas that of the lung, thyroid, liver, esophagus, and the stomach were more common in China than in United States. The proportions of the OMF metastatic lesions originating in the lung, kidney, liver, thyroid, and esophagus in all OMF metastatic tumors were higher than the corresponding primary cancers' prevalent proportions.

CONCLUSIONS

The frequency of developing OMF metastasis is not always consistent with primary cancers' prevalence, which suggests that different cancers have different potentiality to develop OMF metastasis. Cancers of the kidney, liver, lung, thyroid, and esophagus were more likely to spread to the OMF region. In general screening of primary cancer, it would be helpful to take into account the metastatic potentiality of different cancers and primary cancers' prevalence in different countries in the case of occult primary.

Gingival metastasis from a prostate adenocarcinoma: report of a case

Prostate cancer is the cause of 10% of cancer-related deaths in males in the United States. Metastases are found late in the course of the disease. Metastatic tumors of the oral cavity are rare, representing about 1% of oral tumors and affect jaws much more frequently than soft tissues. Metastatic prostate cancer tends to involve the bones of the axial skeleton. In a recent review, 22 cases of metastases to the jawbones from prostate cancer were found in 390 cases. On the other hand, only 1 case of a metastasis to the oral soft tissues was reported. The authors describe the second case of oral soft tissue metastasis from a prostate cancer. The metastatic lesion was located in the gingiva. Clinicians should be aware of oral soft tissue metastases since they can be the first sign of a not yet diagnosed malignant tumor and they can be very easily confused with several different benign lesions.

Metastases to the oral mucosa: analysis of 157 cases

A review of the English-language literature revealed 157 well-documented cases of metastatic lesions to the oral mucosa. Most (64%) were diagnosed in patients in their fifth to seventh decade. The frequency of the primary site differed between genders: for men it was the lung (35.5%) followed by the kidney (16%) and skin (15%); for women it was the breast (24%) followed by the genital organs (17%). The most common oral site was the gingiva and alveolar mucosa (54.8%) followed by the tongue (27.4%), and with much less frequency by the tonsil, palate, lip, buccal mucosa and floor of the mouth. Of the dentulous patients, 79% exhibited the metastatic tumor in the attached gingiva. The clinical appearance of the metastatic oral lesion in most cases resembled hyperplastic or reactive lesions.
