Primary manifestations of extraganglion non-Hodgkin lymphoma (NHL) from T-cells in the oral cavity are rare and often difficult to diagnose. Herein, we describe a case of T-cell NHL with a primary lesion on the lip diagnosed with a 25-year-old woman. The patient reported the appearance of the initial lesion on the upper lip, which advanced to the hard palate and oral mucosa. Histological examination and immunohistochemistry were compatible with peripheral T-cell NHL without further specifications. The proposed treatment consisted of six cycles of multiagent chemotherapy. The patient died from complications of the disease before the third cycle of chemotherapy. Understanding the clinical signs of lymphoma is important for the early diagnosis of this disease to avoid aggressive and potentially fatal behavior.

Aim To evaluate the use of the network of oral health services by children and adolescents with leukemia, according to the phase of cancer treatment, type of dental treatment received, and access barriers. Methods and results An exploratory cross-sectional study carried out in a referral hospital in cancer in northeast of Brazil, with all children and adolescents (3-16 years old) with leukemia who used dental services and who attended the medical consultation in the outpatient clinic between March and August 2016. The analysis of the medical records and a structured interview with caregivers were performed. The majority who used only the specialized network were in a single phase of cancer treatment (49.1%), had oral mucositis treatment (79.2%), and had a time of displacement for oral health services greater than 40 minutes (92.6%). In addition, dental care was centered in the specialized network (76.8%) and during hospitalization (37.7%). Conclusions The findings suggest that the oral health care of these individuals is centered on tertiary care, reflecting a deficiency in communication between the network services, as well as the nonrecognition of the basic network as a caregiver source by its users. Despite this, more research is needed.
