“…39,40 While the gender distribution of Burkitt's lymphoma is in support of published reports, 3,9 the observed slight predilection for the maxilla contrasts with other reports that noted higher occurrence in the mandible. 3,9,14 The results of this study support the observed female predominance for rhabdomyosarcoma 5 but differs from that of a study from Germany. 41 Other malignant jaw tumors such as Hodgkin and nonHodgkin lymphomas, malignant salivary gland tumors, neural and vascular lesions were not observed in this series.…”

“…The reason for this difference may be explained by the exclusion of cystic and reactive lesions from the previous studies. 2,[12][13][14] Generally, studies from the developed countries reports higher proportion of malignant jaw lesions than benign lesions when compared to reports from Africa. This observed difference may be explained in terms of relatively lower life expectancy among Africans compared to their Western counterparts.…”

“…This is evident in the fact that in our 12-year audit, not a single case was reported in this study, neither has it been reported across the African continent [31]. However, in China it is reported as the 2nd most frequent tumor type after PSA [15,31]. Eveson and Cawson found peak incidence of benign tumours in the 6th decade and malignant in the 7th decade.…”

Salivary gland tumours (SGT) are rare, comprising about 5% of head and neck tumours with a higher incidence reported in the western compared with the African centres. There are few studies on SGTs that have been conducted in Africa. A descriptive retrospective study was done to describe the demographic characteristics, site distribution and histological patterns of SGT at a University teaching hospital in Kenya over a 12-year-duration. There were 132 SGTs out of 2426 biopsies of head and neck tumours, the age range was between 8 to 80 years (mean = 43.6 yrs) and the modal age was 50 yrs. The percentage of tumours arising from minor salivary glands (MiSG) (67%) were twice than that from the major salivary glands (MaSG) (33%). The sites most affected for the Misg was the palate and for the MaSG was the submandibular gland. Pleomorphic salivary adenoma (PSA) (40.2%) was the most common benign SGT while adenoid cystic carcinoma) (ACC) (20.5%) was the most frequent amongst the malignant type. The overall male:female ratio was almost 1:1. However, there were more females than males with benign SGTs, whereas an equal gender distribution was noted in malignant SGT. Benign and malignant SGT occur at a younger age. MiSGs of the palate were most frequent site of tumour and the least frequent is the sublingual gland. More than 50% of SGT were malignnant and hence any SGT should raise a high index of suspicion.

“…El tratamiento de elección es la cirugía, con reportes de evolución favorable, aunque puede recidivar por exéresis incompleta 7 . La edad de aparición está entre los 30 y los 60 años 8,9 ; algunos autores sugieren que se diagnostica en la raza negra con mayor frecuencia, y sus dimensiones varían entre 0,3 y 10 cm 10 . El trauma puede aparecer como antecedentes personales, y se han publicado casos en familiares que sugieren una herencia autosómica dominante 11 .…”

Condroma del espacio parafaríngeo, reporte de un caso

ResumenIntroducción. El condroma es una neoplasia benigna de origen mesenquimal y de etiología desconocida, muy infrecuente en los tejidos blandos debido a su constitución de células de cartílago maduro sin hueso; sin embargo, son frecuentes las calcificaciones focales. Al presentarse en cabeza y cuello, suele hacerlo en el maxilar o el paladar duro, y son pocos los reportes de este tumor en el espacio parafaríngeo. Se reporta el caso de una paciente de 68 años de edad, que acudió a consulta por dolor en el paladar blando, cefalea y dolor paratiroideo izquierdo asociado a disfagia de cuatro años de evolución. Se practicaron los estudios pertinentes y, finalmente, se confirmó el diagnóstico de condroma mediante biopsia. Discusión. Los condromas muy rara vez se encuentran en los tejidos blandos, por lo cual se sugiere que el diagnóstico sea cuidadosamente orientado para descartar una posible malignidad de la lesión y que los controles posquirúrgicos sean frecuentes. Palabras clave: condroma; faringe; neoplasias faríngeas; diagnóstico. AbstractIntroduction: Chondroma is a benign neoplasm of mesenchymal origin and of unknown etiology, very infrequently appearing in the soft tissues due to its constitution of mature cartilage cells without bone; however, they usually present focal calcifications. When occurring in the head and neck, they usually appear in the jaw or hard palate. Just a few cases of this pathology are reported in the pharynx. Materials and Methods:We present a case of a female 68 years old, who came to the clinic due to pain in the soft palate, headache and left parathyroid pain associated with dysphagia, of four years of evolution. Corresponding studies were carried out and finally the diagnosis of chondroma was confirmed by biopsy. Discusion: Chondromas are rarely found in the soft tissues, suggesting that the diagnosis should be carefully oriented to rule out possible malignancy of the lesion and that post-surgical controls should be frequent.
