Synchronic nasopharyngeal and intraparotid warthin tumors: a case report and literature review
2014
Warthin tumor is the second most frequent benign salivary gland tumor after pleomorphic adenoma; it occurs almost exclusively in the parotid gland and peri-parotideal lymph nodes, although it may rarely present in other locations. It may be multicentric and bilateral in a small percentage of cases. Nasopharyngeal Warthin tumor is very rare, and the presence of a synchronic WT involving nasopharynx and parotid is an exceptional event, as it has been described only twice in the literature. In this article we report an additional case of a synchronic Warthin tumor and review the related literature. Key words:Warthin tumor, synchronic WT, multicéntrico, nasopharynx.
Soft palate preservation after tumor resection with transoral laser microsurgery
2012
Background: Management and preservation of the soft palate is dependent on clinical stage and tumor histology. However, available literature is scarce regarding the palate preservation with the use of laser CO 2 . Objectives : We report the results obtained after management with laser surgery and soft palate preservation in three patients with salivary gland neoplasms. Method: Three patients with minor salivary gland tumors were treated by means of transoral laser microsurgery. All tumors were assessed using magnetic resonance imaging. All tumors were >3 cm. Soft palate function was preserved and reconstruction was performed with primary closure. Patients began oral feeding the same day and…
Hybrid salivary gland tumor of the upper lip or just an adenoid cystic carcinoma? Case report
2010
A 65 year-old male patient with a one year-duration tumoral growth located in the upper lip was diagnosed on incisional biopsy as epithelial-myoepithelial carcinoma. After wide surgical excision the histopathological analysis revealed the lesion was composed predominantly (>90%) of adenoid cystic carcinoma. In new sections it was found a very small and isolated area of adenoid cystic carcinoma at the bottom of the incisional biopsy. As surgical margins were free of lesion, no adjuvant treatment was given. The occurrence of a transitory ischaemic attack at 36 months of follow-up led to a neurological and MRI evaluation, which disclosed a well-defined 3.5x3 cm lesion suggestive of metastasis,…
Expression of hormonal receptors in osteosarcomas of the jaw bones: clinico-pathological analysis of 21 cases
2013
Background: Sexual hormones have an important role in many hormone-dependant tumors like breast and prostate carcinomas, and also a relationship has been found with bone metabolism and bone tumors. Some studies have demonstrated that the expression of hormonal receptors (HR) in osteosarcomas (OS) of long bones is associated with gender, histological grade, histological type, and possibly may be connection with pathogenesis and evolution. However, to our knowledge there are no studies of HR in osteosarcomas of craniofacial bones (OS-CF). Objectives: To assess the expression of hormonal receptors in OS-CF. Material and Methods: Twenty one cases of OS-CF were included in this study. Clinical o…
Upper lip malignant neoplasms : a study of 59 cases
2011
Objectives: To present the demographic data, clinico-pathologic features and therapeutic outcome of a series of upper lip malignancies. Study Design: Retrospective study at a single Cancer Institution in Mexico City during a 14-year period. Results: There were 59 cases, (30 males and 29 females); age range: 14 to 106 years (mean: 73 yr.). Antecedents of ultraviolet light and tobacco exposure were found in 20 (33.9%) and 16 cases (27%) respectively. There were 35 squamous cell carcinomas (59.3%), 19 basal cell carcinomas (32.2%) and one case each (1.7%) of adenocarcinoma NOS, adenoid cystic carcinoma, angiosarcoma, Merkel cell carcinoma and melanoma. There were 14 cases in stage I (23.7%), 1…
Laser resection of liposarcoma of the hypopharynx
2009
Liposarcomas represent between 15 and 18% of all sarcomas with the most common site being the extremities and retroperitoneum. Liposarcomas of the head and neck are rare, with an estimated incidence representing 3 to 5.6% of all liposarcomas. Liposarcomas most commonly present in the soft tissues of the neck. Primary liposarcoma of the hypopharynx (piriform sinus) is extremely rare. The symptoms presented are principally dysphagia, dyspnea, dysphonia, airway obstruction and sensation of a foreign body. Treatment of choice is surgery, and the literature describes the performance of lateral pharyngotomy, simple excision and even total laryngectomy. We present the case of a 23-year-old patient…
