Gingival carcinoma cuniculatum mimicking a reactive/inflammatory process

ABSTRACT Carcinoma cuniculatum (CC), a rare variant of oral squamous cell carcinoma, presents well-differentiated neoplastic epithelial cells infiltrating the underlying submucosal or bone tissues, forming the so-called "rabbit burrows" filled with keratin. A 67-year-old female patient was referred complaining of a painless tumoral mass in the left mandibular body, with several months of evolution. Previous history indicated extraction of the teeth #37 and #38 and diagnosis of chronic suppurative osteomyelitis. A deep incisional biopsy revealed CC. Due to its microscopic features, suggesting an inflammatory or reactive process, strict clinicopathological correlation is necessary for the correct diagnosis of CC.RESUMEN El carcinoma cuniculatum (CC), una variante del carcinoma de c élulas escamosas oral, presenta células epiteliales neoplásicas bien diferenciadas que se infiltran en la submucosa o en el tejido óseo subyacente, formando la llamada "madriguera de conejo", rellenada con queratina. Reportamos el caso de una paciente de 67 años con quejas de una masa tumoral a sintomática en el cuerpo mandibular izquierdo con varios meses de evolución. La historia previa apuntó exodoncia de los dientes 37 y 38 y diagnóstico de osteomielitis supurativa crónica. Una biopsia incisional profunda reveló CC. Debido a las características microscópicas, que sugirieron un proceso in...

ConclusionMicroelectrodes and radiofrequency in transoral laryngeal surgery produced mild tissue damage and offer an excellent alternative to the use of high frequency energy.ResumoIntroduçãoEm 2006 e 2009, relatamos os níveis de danos teciduais agudos e crônicos após cordectomia associados ao uso de microeletrodos utilizando energia de alta frequência. Em 2010, passamos a utilizar radiofrequência em vez de eletrogeradores de alta frequência.ObjetivoO objetivo deste estudo é avaliar a lesão tecidual aguda na laringe após cordectomia utilizando microel...

ConclusionThe close relationship between HPV and oropharyngeal squamous cell carcinoma could not be shown in larynx malignancy in many studies, including our study. Our findings support a limited role of HPV in laryngeal carcinogenesis. Protein16 is not a reliable surrogate for HPV status in laryngeal cancers and is not a predictor of laryngeal cancer survival. Supraglottic localization of tumor was determined to be increased in protein16 positive cases. The correlation between protein16 positivity and supraglottic area location was determined to be statistically significant. There is a need for more populated clinical tri...

Authors: Chang MS, Chen NC, Hsu CY, Huang CW, Lee PT, Chou KJ, Fang HC, Chen CL Abstract Background: Encapsulating peritoneal sclerosis (EPS) is a serious complication of peritoneal dialysis (PD), with high morbidity and mortality that requires an early diagnosis for effective treatment. PD withdrawal and bacterial peritonitis are important triggers for the onset of EPS. However, few studies have focused on cases of PD withdrawal without a clinical diagnosis of peritonitis, cirrhosis, or carcinomatosis. We aimed to compare the clinical characteristics and computed tomography (CT) images of patients with or without ...
