Carcinoma de lábio com prognóstico sombrio devido conduta médica inadequada

The Squamous Cell Carcinoma is what more happens among the oral cancers, being considered sweats incidence in more than 90%. As important prognostic factor competes the early diagnosis and the immediate institution of the treatment, that it can involve radiotherapy and chemotherapy besides the surgery. The initial lesions don’t offer great diagnostic difficulties and now complemental laboratory exams define the diagnosis quickly, In the present report, the initial medical conduct was inadequate, with incomplete interpretation of the laboratorial result and adoption of inadequate therapeutic conduct, what resulted in constant evolution of the lesion. The patient came to the consultation with that medical history, after six months of the first attendance accomplished in another center. To the physical exam, infiltrative ulcerated lesion was observed in the lower lip, with having accentuated tissue loss superficially. The patient accused spontaneous pain and she did use an ointment, recommended six months ago for occasion of the first attendance. As diagnostic conduct was indicated the accomplishment of cytology and biopsy, being defined the diagnosis of Squamous Cell Carcinoma. The patient was immediately guided to the medical service of its municipal district for manegement of the specialized oncologic treatment. The patient was submitted the surgery followed by radiotherapy, being verified involvement of another structures by contiguity. Now, the patient meets abed, without viable perspectives of cure.

Oral focal mucinosis: clinical case presentation with a focus on aesthetic and functional surgical resolution

Introduction: When planning excisional surgery, alterations in the oral mucosa, particularly in esthetically important areas, represent a challenge. For cases involving an exophytic lesion with a vegetative tumoral aspect, a clinician may prioritize obtaining a definitive diagnosis by histopathologic and histochemical examinations over the preservation of esthetics or maintenance of the involved tooth. Case Presentation: A painless, hard lesion with normal coloration was present in the maxillary left central incisor of a patient for at least 6 years. A biopsy was performed to preserve oral mucosa and a treatment plan was established that included endodontic retreatment and prosthetic restoration. The histopathologic diagnosis was oral focal mucinosis, an uncommon and poorly characterized type of lesion. Conclusion: A conservative biopsy of the lesion facilitated an accurate diagnosis, promoted the patient’s comfort, and achieved satisfactory esthetic results.

Actinic Cheilitis: epidemiological study in a riverine population of northern Brazil
