Quiste radicular residual / A residual radicular cyst

En la región cervicofacial los quistes de los maxilares de origen odontogénico constituyen una afección relativamente importante, los más frecuentes son los quistes radiculares. Se presentó un paciente masculino de 23 años de edad con un quiste radicular residual extenso que ocupaba la zona mandibular posterior izquierda, y acude a consulta estomatológica de la Clínica «Celia Sánchez Manduley» por un aumento de volumen que causa asimetría facial notable de la hemicara izquierda, de tres centímetros de diámetro, indoloro, asintomático, con 6 meses de evolución y consistencia dura; además refiere tratamiento de exodoncia de molar inferior en la zona (37) hace 2 años. Se indicó radiografía periapical y panorámica donde se observó zona radiolúcida bien definida de 35 a 38 con reabsorción de raíz mesial de 38, distal de 36 y movilidad dentaria grado II en ambos dientes. Se realizó exéresis de la lesión cuyo estudio histológico informó un quiste radicular residual.

Jaw cysts of odontogenic origin constitute a relatively important condition in the cervicofacial region, where radicular cysts are the most frequent. We present a 23-year-old male patient who come to "Celia Sánchez Manduley" Dental Clinic with an extensive residual radicular cyst that occupied his left posterior mandibular area and an increase in volume that caused him a notable facial asymmetry in the left side of his face, of three centimeters in diameter, painless, asymptomatic, with 6 months of evolution and hard consistency; he also mentions a lower molar extraction treatment in area (37) 2 years ago. Periapical and panoramic X-rays were indicated where a well-defined radiolucent zone of 35 to 38 was observed with mesial root resorption of 38, distal of 36 and grade II dental mobility in both teeth. Exeresis of the lesion was performed, whose histological study reported a residual radicular cyst.

A rare case of co-infection with pulmonary tuberculosis and oronasal actinomycosis / Caso raro de coinfecção tuberculose pulmonar e actinomicose oronasal

Oronasal actinomycosis is an infection seldom described in the literature, especially in the form of a co-infection with pulmonary tuberculosis. We report the case of a 48-year-old male admitted to the isolation ward due to active pulmonary tuberculosis, with a history of diabetes and alcohol abuse. While hospitalized, the patient complained of dysphagia and nasal regurgitation of food. The examination of the oral cavity revealed an oronasal fistula. The infecting agent was identified, and the treatment was successful. We also present a brief review of the literature, as well as a full description and discussion of the process of investigating this rare clinical case.

Durante a internação, o paciente referiu queixas de disfagia e regurgitação alimentar por via nasal. O exame da cavidade oral revelou uma fístula oronasal. O agente infeccioso foi identificado, e o tratamento foi realizado com sucesso. Apresentamos também uma breve revisão da literatura e uma descrição e discussão completa do processo de investigação deste raro caso clínico.
