Maxillary bone metastasis, as an early sign of breast cancer; an unusual & rare site of metastasis from the common cancer.

Oral cavity metastases are considered rare and represent approximately 1% of all oral malignancies. Due to their rarity and atypical clinical and radiographic appearance, metastatic lesions are considered a diagnostic challenge. In this article we present a rare, unusual & exceptional case of left maxillary mass which on further evaluation leading to diagnosis of left breast carcinoma with metastasis to isolated left maxillary bone. Sixty five year old postmenopausal woman of low socioeconomic status with good performance status presented with a 3 months history of progressive pain and swelling in the left maxillary region. Fine Needle Aspiration Cytology (FNAC) from the maxillary mass shows invasive ductal carcinoma. On further clinical, radiographic, and histopathological examination findings from the breast lesion confirmed the diagnosis of hormone receptor positive metastatic breast carcinoma. In view of painful metastatic maxillary lesion with breast disease she was managed with a palliative radiotherapy to the maxillary lesion and palliative chemotherapy with Doxorubicin-Cyclophosphamide and bhisphosphonate-Zolendronic acid. Patient responded very well to palliative radiotherapy and chemotherapy, in view of hormone receptor positive breast cancer, now she is on Tab. Anastrazole 1 mg once a day along with monthly Zolendronic acid injection since last 13 months without any symptoms of disease evolution. A high index of clinical thought of metastatic cancer to maxilla is necessary when evaluating patients who complain of maxillary pain and swelling without a history of pain or swelling in the head and neck & non-head and neck region. To the best of our knowledge, this is the first reported case of a metastatic isolated solitary maxillary bone metastasis presenting as an early sign of breast cancer.

Feasibility and clinical value of CT-guided 125I brachytherapy for metastatic soft tissue sarcoma after first-line chemotherapy failure.

PURPOSE: To evaluate the feasibility and usefulness of computed tomography (CT)-guided iodine125 (125I) brachytherapy for patients with metastatic soft tissue sarcoma (STS) after first-line chemotherapy failure. METHODS: We recruited 93 patients with metastatic STS who had received first-line chemotherapy 4-6 times but developed progressive disease, from January 2010 to July 2015; 45 patients who had combined 125I brachytherapy and second-line chemotherapy (Group A), and 48 patients who received second-line CT only (Group B). RESULT: In Group A, 49 125I seed implantation procedures were performed in 45 patients with 116 metastatic lesions; the primary success rate was 91.1% (41/45), without life-threatening complications. Local control rates at 3, 6, 12, 24 and 36 months were 71.1%, 62.2%, 46.7%, 28.9% and 11.1% for Group A, and 72.9%, 54.2%, 18.8%, 6.3% and 0% for Group B. Mean progression-free survival differed significantly (Group A: 7.1±1.3 months; Group B: 3.6 ±1.1 months; P<0.001; Cox proportional hazards regression analysis), but overall survival did not significantly differ (Group A: 16.9 ±5.1 months; Group B: 12.1 ± 4.8 months). Group A showed better symptom relief and quality of life than Group B. CONCLUSION: CT-guided 125I brachytherapy is a feasible and valuable treatment for patients with metastatic STS. KEY POINTS: • 125 I brachytherapy is feasible and valuable for treating metastatic soft tissue sarcoma. • 125 I brachytherapy represents a prominent activity in disease control. • 125 I brachytherapy can achieve better symptom relief and quality of life.

Breast cancer metastases to the head and neck: Case series and literature review.

Breast cancer is the most common cancer in women and is the second most common cause of cancer-related death. Despite the relatively high prevalence of this disease, breast cancer manifestations in the head and neck are relatively rare. Supraclavicular lymphadenopathy and bony metastases to the mandible and maxilla are the most common manifestation of breast cancer in the head and neck. Head and neck metastases are the first presentation of distant disease in approximately one-third of cases. The prognosis of breast cancer with distant metastases to the head and neck is generally poor, and the management of these lesions is controversial. Overall extent of disease and individual patient prognosis must guide treatment decisions. Atypical cases including maxillary sinus mass, jugular foramen mass, and dermal metastases are presented. Metastatic breast cancer is a rare diagnosis in the head and neck, yet metastatic disease from an infraclavicular primary deserves inclusion on any comprehensive differential diagnosis list. In women, breast carcinoma is the most common infraclavicular primary to metastasize to the head and neck.

Cervical metastases of oral maxillary squamous cell carcinoma: A systematic review and meta-analysis.

Cervical treatment of oral maxillary squamous cell carcinoma (SCC) remains controversial. We determined the metastases incidence and evaluated its predictive factors. Systematic review and meta-analysis was conducted of 23 Chinese and English-language articles retrieved from PubMed, Ovid, Embase, Cochrane Library, China National Knowledge Infrastructure, and Chinese Scientific and Technological Journal databases. Total cervical metastases and occult metastases rate was 32% and 21%, respectively. Positive lymph node detection was likeliest from levels I to III. The maxillary gingival metastases rate was higher than that of the hard palate. Advanced-stage tumors had higher metastatic risk than early-stage tumors. Well-differentiated tumors had a significantly higher metastases rate than medium and poor-differentiation tumors. N0 cases had survival benefit compared with N+ cases. Metastases rate of oral maxillary SCC correlates significantly with T classification and pathological stage. T and N classifications impact outcome significantly. Therefore, levels I to III selective neck dissection is recommended for patients with T3/4 cN0 disease. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2335-E2342, 2016.

Metastatic cervical carcinoma of the jaw presenting as periapical disease.

AIM: To present a case report of a metastasis from cervical cancer to the maxilla, which was misdiagnosed as periapical disease and to caution clinicians that metastases could have a disguised clinical presentation that must be taken into account in the differential diagnosis of periapical disease in oncologic patients. SUMMARY: Although metastatic tumours of the jaws are uncommon, they may mimic benign inflammatory processes and reactive lesions. The ability of metastatic lesions to mimic periapical disease is discussed and a brief review of the literature is presented, emphasizing the importance of correct diagnosis to prevent delay in diagnosing cancer. Attention should therefore be given to the patient's medical history, especially of those with a previous history of cancer, and all dental practitioners should be aware of the possibility of metastases that may be confused with periapical disease. Finally, endodontists are well placed to recognize malignant and metastatic oral lesions during the initial clinical stages, given that their treatments are usually based on frequent dental appointments and long-term follow-ups.

Metstatic papillary thyroid carcinoma to maxilla: a rare case.

Metastatic involvement of oral osseous and soft tissues constitutes nearly 1% of all oral malignancies. However, maxillary involvement is uncommon and this phenomenon is even less likely when the primary source is thyroid. A rare case of papillary thyroid carcinoma metastatic to maxillary right posterior alveolar process and sinus in a 43-year-old woman is described and the spectrum of metastatic oral disease is reviewed. The importance of including metastasis in the differential diagnosis of jaw lesions is also emphasized.

Metastatic renal cell carcinoma to the jaws: report of cases.

Renal cell carcinoma (RCC) is one of the most frequent urological malignancies in adults. RCC often metastasizes to other organs, but rarely to the oromaxillofacial region. Metastatic tumors to the jaws are also unusual. In this report, we present two cases of RCC metastasis to the jaws. Metastatic RCC is resistant to radiotherapy and chemotherapy, so surgery is the primary therapeutic choice. This report describes the diagnostic procedures utilized and the therapeutic process in the two cases. The differential diagnosis and treatment methods are discussed.

Synchronous antiresorptive osteonecrosis of the jaws and breast cancer metastasis.

Antiresorptive osteonecrosis of the jaws (ARONJ) is a significant and poorly understood oral complication that may affect patients receiving antiresorptive agents, such as intravenous bisphosphonate therapy. There are scarce reports of the coexistence of ARONJ and metastasis at the same jaw site in the English-language literature. In the present case, a 60-year-old white woman was referred for the evaluation of a nonhealing extraction socket. The patient was undergoing treatment with intravenous zoledronic acid to metastatic breast cancer in bone, and her medical history and clinical characteristics led to the diagnosis of ARONJ. Nevertheless, histologic analysis showed a fragment of necrotic bone and bacterial colonies associated with malignant epithelial cells that were confirmed to be metastatic breast adenocarcinoma. This case showed that jaw metastasis can occur at the same time and site of ARONJ, making diagnosis and management challenging.

Maxillofacial metastasis from breast cancer.

Metastatic tumors to paranasal sinuses are exclusively rare. In this paper, we report a case of breast carcinoma metastasizing to the right maxilla. The metastasis occurred 5 years after radical mastectomy and presented as a primary sinonasal mass. The diagnosis was confirmed with histopathologic and immunohistochemical examination however the patient died before starting any specific treatment because of tumor bleeding.

Hepatocellular carcinoma metastasis to the maxilla: a rare case.

The manifestation of metastatic malignant disease in the oral cavity can present in a number of ways and may mimic benign conditions. This case reports a rare presentation from a metastasis of a hepatocellular carcinoma that had invaded the attached gingiva of the maxilla and which on initial inspection could have been misdiagnosed as a pyogenic granuloma. With the advent of new classes of drugs to manage this disease it could be expected that this presentation may become more common.

Maxillary surgical seeding of a clival chordoma.

Seeding on surgical pathway is a rare form of clival chordoma treatment failure. We report the case of a 42-year-old male with a clival chondroid chordoma removed by a sublabial transsphenoidal approach followed by proton beam radiotherapy, who developed a maxillary bone recurrence 3 years after surgery.

Maxillofacial metastasis of genitourinary origin. A report of 3 cases and review of the literature.

INTRODUCTION: The maxillofacial region can harbour a wide range of primary tumours, as well as secondary tumours spreading from distant sites. Rare, though nevertheless important among the latter are genitourinary tumours, such as clear cell renal carcinoma and cervical cancer. Diagnosis of the maxillofacial metastasis sometimes precedes that of the original site, though in other cases the metastasis may arise many years after treatment of the primary tumour. CASE REPORT: We present three cases of maxillofacial metastasis of genitourinary tumours, two clear cell renal adenocarcinoma and squamous cell carcinoma of the uterine cervix. The patients were referred our hospital service for diagnosis and treatment, after having been initially evaluated for buccodental symptoms. DISCUSSION: The appearance of a maxillofacial tumour, initially with the aspect of a primary tumour, may sometimes be the consequence of haematogenous dissemination from another site, such as these surprising cases originating in the genitourinary area. If disseminated metastatic disease is suspected, an extensive oncological screening should be done to evaluate the best therapeutic option in each patient.

Metastatic papillary thyroid carcinoma to the maxilla: case report and literature review.

Metastatic tumors to the oral cavity are uncommon and a thyroid origin is considered exceedingly rare. A case of metastatic papillary thyroid carcinoma (PTC) presenting as a painful swelling in the right posterior maxilla of a 63-year-old male is reported here. The patient had been diagnosed with PTC 2 years ago and treated with thyroidectomy and radioactive iodine treatment. Radiographically, the metastatic lesion presented as a poorly-defined radiolucent lesion around an impacted maxillary third molar in the right maxilla. Histopathologic examination revealed features of PTC which was immunohistochemically positive for pancytokeratin, keratin 19 and thyroglobulin. Imaging studies revealed the presence of residual maxillary and neck disease as well as additional metastatic lesions in the sternum, ribs, and left tibia. A thorough review of the English language literature revealed only 36 previously published cases of thyroid cancer metastases to the oral cavity, the demographic and clinicopathologic features of which are summarized.
