Fibroma de Células Gigantes en Lactante Mayor / Giant Cell Fibroma in Older Infant. A Case Report

RESUMEN: El fibroma de células gigantes es considerado un tumor benigno no neoplásico de la mucosa oral. Este aparece en las primeras tres décadas de la vida, siendo relativamente raro en pacientes pediátricos. Puede encontrarse principalmente en la encía mandibular, mostrando predilección por el sexo femenino. Clínicamente se presenta como un crecimiento indoloro, de base sésil o pediculado, que generalmente se confunde con otras lesiones de tipo fibrosas como los fibromas de irritación. Histológicamente, se distingue por presentar fibroblastos estrellados con la presencia de células gigantes multinucleadas cerca de la lámina del epitelio. Presentamos el caso de una paciente femenino de un año de edad la cual presenta crecimiento nodular indoloro en relación con una superficie del paladar de 51 y 61. Teniendo en cuenta el tamaño y la ubicación de la lesión, se realizó escisión, biopsia y se envió para análisis histopatológico que confirmó la lesión como fibroma de células gigantes.

ABSTRACT: The giant cell fibroma is a benign nonneoplastic fibrous tumor of the oral mucosa. It occurs in the first three decades of life and is relatively rare in pediatric patients. It can be found predominantly in the mandibular gingiva, showing predilection for females. Clinically it presents as a painless, sessile, or pedunculated growth which is usually mistaken for other fibrous lesions like irritation fibroids. Histologically it is distinguished by the presence of stellated fibroblasts along with multinucleated giant cells near the epithelial sheet. We present a case where a one-year-old female patient presented with a painless nodular growth in relation to a palatesurface of 51 and 61. Considering the size and location of the lesion, excision and biopsy were performed and sent for histopathological analysis which confirmed the lesion as giant cell fibroma.

Florid cemento-osseous dysplasia and peripheral giant cell granuloma in a patient with neurofibromatosis 1

Abstract: We report a 35-year-old mulatto female patient with neurofibromatosis Type 1 who presented with facial asymmetry. The patient had two lesions: florid cemento-osseous dysplasia associated with peripheral giant cell granuloma. She was referred for surgical treatment of the peripheral giant cell granuloma and the florid cemento-osseous dysplasia was treated conservatively by a multidisciplinary team. So far, no changes have been observed in the patient's clinical status. We observed no recurrence of peripheral giant cell granuloma. To the best of our knowledge, the present case is the first report of a patient with neurofibromatosis Type 1 associated with a giant cell lesion and florid cemento-osseous dysplasia.

Giant cell reparative granuloma concurrent with squamous cell carcinoma of the temporal bone: a case report and review of the literature.

A case of giant cell reparative granuloma concurrent with squamous cell carcinoma of the right temporal bone in a 44-year-old man with clinically presenting otorrhea from the mass of the right acoustic canal with hearing loss is reported. The histopathological examination of the lesion characterizes by multinucleated giant cells with in a fibroblastic stroma and area of keratinizing squamous cell carcinoma. GCRG may have been a local reaction provoked by the squamous cell carcinoma. Clinical and pathological features with briefly reviewed relevant literatures of temporal GCRG describing 24 cases are discussed. The patients have the mean age of 34.8 years. The ages of the patients ranged from 4 months to 72 years old. Temporal bone GCRG shows a male predilection of approximately 3:1. The frequently presenting symptoms of temporal bone GCRG are hearing loss, mass, tinnitus, otalgia, otorrhea, vertigo, headache, facial weakness, and diplopia. This is the first reported description in the literature of temporal bone GCRG concurrent with squamous cell carcinoma.

An autopsy case of sudden death in a patient with giant cell myocarditis.

We present a case of a 28-year-old male weight lifter who died suddenly while driving a bicycle. Forensic autopsy and histopathological examinations revealed granulomatous lesions in the myocardium and hilar lymph nodes. The latter had massive caseation necrosis, epithelioid granulomas and Langhans' giant cells suggestive of tuberculosis. However, the myocardium showed predominantly multinucleated foreign body and myogenic giant cells, lymphocytes, plasma cells, macrophages, eosinophils. Staining for acid-fast bacilli was negative. The present case highlights the difficulty in establishing whether the granulomatous lesions in the hilar lymph nodes and the myocardium are incidental findings or whether they are related by the same pathogenetic mechanisms.

Giant cell reparative granuloma of the base of the skull presenting as a parapharyngeal mass.

Giant cell reparative granuloma is an infrequent non-tumoral lesion affecting the maxillary and mandibular bones and only rarely, the cranial bones. We report a case of giant cell reparative granuloma of the base of the skull in a 12-year-old female who presented with a parapharyngeal mass. Computerized Tomography (CT) showed the intracranial extension and destruction of surrounding bones.

Granuloma gigantocelular central en un niño de 7 años de edad / Giant cell granuloma in a 7 year-old boy

Realizado un breve relato acerca de la naturaleza de G.G.C.P., su presentación clínica, radiográfica, histopatológica y diagnóstico diferencial con otros lesiones que se presentan en cavidad bucal, se indica la terapia correspondiente. Seguidamente se presenta el caso clínico de un G.G.C.C. con asiento en el maxilar inferior, en un niño de 7 años de edad, caracterizado por un crecimiento acelerado y recidivas luego de cada extirpación, lo que llevó a la resección del cuerpo mandibular, con posteriores complicaciones generales (PTA y LE), quedando el mismo con graves secuelas físicas e inmunológicas
