Carcinoma epidermoide de seno maxilar: a propósito de un caso / Squamous cell carcinoma of the maxillary sinus: a case report

Fundamento: el carcinoma epidermoide de seno maxilar es de poca frecuencia, capaz de provocar compromiso estético-funcional por lo que su diagnóstico temprano permitirá al paciente un mejor pronóstico. Objetivo: exponer aspectos clínicos del carcinoma epidermoide de seno maxilar. Caso clínico: paciente masculino de raza blanca, 64 años de edad, con aumento de volumen en región orbito-cigomática izquierda de un mes de evolución. La tomografía axial computarizada de senos paranasales reveló imagen heterogénea sugestiva de tumor de seno maxilar del lado izquierdo. El diagnóstico histopatológico reportado fue de carcinoma epidermoide bien diferenciado. Se instauró el tratamiento con quimioterapia y radioterapia concurrente. El motivo de mostrar este caso consiste en aportar experiencias que permitan el diagnóstico temprano de la enfermedad y así mejorar el pronóstico para el paciente. Conclusiones: un examen clínico minucioso conducirá a un diagnóstico precoz de estas enfermedades que presentan una evolución tórpida y carecen de signos patognomónicos sobre todo en sus estadios iniciales. Es de vital importancia el papel protagónico que tiene la Atención Primaria de Salud para la detección del cáncer el cual constituye una de las primeras causas de muerte en Cuba (AU)

Background: squamous cell carcinomas of maxillary sinus are rare. It causes esthetic-functional compromise. Therefore, its early diagnosis will allow the patient better prognosis. Objective: to expose clinical aspects of squamous cell carcinoma in maxillary sinus. Case report: a clinical case is reported from 64-year-old white male patient with swelling over the orbit-zygomatic area that progressed over 1 month. The paranasal sinus CAT scan showed a heterogenic image suggesting a left maxillary tumor. The histopathological diagnosis reported a well- differentiated squamous cell carcinoma. Chemotherapy and radiotherapy can be used in this case. The scope of showing this case is to provide some aspects that allow the early diagnosis of the aforementioned disease as well as to improve the patients prognosis.Conclusions: the deep clinical examination in patients will allow a soon diagnosis of these pathologies that present a torpid evolution lacking pathognomonic signs mainly in first stages. It is of paramount importance the role of the Primary Health Service in the early detection of cancer, which constitutes one of the main causes of death in Cuba (AU)

Case report. Metastatic renal cell carcinoma to the left maxillary sinus.

Metastatic tumors in the paranasal sinuses are very rare. The origin of metastatic tumors in the paranasal sinuses is often renal cancer. Renal cell carcinomas are known for their tendency for early metastasis, and symptoms due to the metastatic lesion may be the only initial manifestation. In this paper, we deal with the case of a 35-year-old male patient who presented with a mass in the left maxillary region. The presence of a primary renal cell carcinoma was recognized only after surgical removal of the metastatic tumor. The presentation, diagnosis and treatment of this tumor are discussed with a review of the literature.

Reactive post-radiotherapy bone formation in the maxilla.

OBJECTIVE: High-dose radiation therapy affects bone metabolism, and therefore post-radiotherapy bone formation is an uncommon finding. This case describes an unusual ossification in the maxillary region identified after head and neck radiotherapy. RESULTS: A 45-year-old female patient was submitted to maxillary surgical resection and orbital exenteration due to squamous cell carcinoma. Radiotherapy post-surgery was performed because of compromised surgical margins. After 4 months of the conclusion of radiotherapy, the patient presented a bone exposition at surgical site. Surprisingly, the oral examination and computed tomography revealed a new formation of the right palatine vault and bone formation filling the nasal and orbital cavity. The incisional biopsy discarded residual disease or osteoradionecrosis and showed normal tissue. CONCLUSIONS: To the best of the authors' knowledge, this is the first case of wide bone formation as an early effect of head and neck radiotherapy.

Adenoid cystic carcinoma and mucoepidermoid carcinoma of the maxillary sinus: report of a 44-year experience of 25 cases from a single institution.

PURPOSE: The aim of this study was to analyze the clinicopathologic characteristics of all cases of adenoid cystic carcinoma (ACC) and mucoepidermoid carcinoma (MEC) arising in the maxillary sinuses treated in a single institution. PATIENTS AND METHODS: From 1953 to 1997, 18 ACCs and 7 MECs from the maxillary sinus were studied. Clinical data were obtained from the medical records and microscopic slides were reviewed. RESULTS: Mean age was 45.9 years (range, 13 to 77 years) and TNM staging revealed 88.9% of ACCs at advanced clinical stages, while 57.1% of the MECs were initial clinical stages. Surgery combined with radiotherapy was the most common treatment. Follow-up showed 88.8% of ACC patients died from the tumor, while 42.8% of patients with MEC are alive without disease. CONCLUSION: Maxillary sinus ACC and MEC are uncommon tumors and a patient's prognosis depends on the clinical stage and histologic type; MEC has shown a better outcome.

Postoperative radiotherapy in the management of cancer of the maxillary sinus.

This report comprises 149 patients with carcinoma of the maxillary sinus treated with radical surgery and postoperative radiotherapy (5500 to 6000 cGy in 6 weeks) between 1963 and 1980 at the Instituto Nacional de Enfermedades Neoplasicas of Lima. Permanent local control was observed in 67.1% of the cases with a 5-year actuarial survival of 36.2% and a corrected survival for death not due to cancer of 42.3%. The ultimate local and distant failures were 61%. Data were analyzed regarding stage of the disease, radiotherapeutic technique and its influence on local control, complications, and patterns of relapse. The data indicate that the stage of the tumor influences survival. Because of the natural history of this disease, local control is paramount.
