[Carney triad: Report of one case]. / Tríada de Carney. Una rara asociación de tumores infrecuentes: Caso clínico.

Carney described a disorder characterized by the presence of several uncommon tumors which were pulmonary chondromas, gastric sarcomas and extra-adrenal paragangliomas. We report a 14 year-old girl in whom multiple gastric tumors were discovered during a study of an iron deficiency anemia and was subjected to a partial gastrectomy. At 25 years of age, she developed several pulmonary chondromas and at 33 years, a mediastinal tumor with features of an extra-adrenal paraganglioma was found. At 35 years of age, a total gastrectomy was performed to remove a gastrointestinal stromal tumor with excision of peritoneal and lymph node metastasis. One year later, the patient died due to liver failure secondary to liver metastases.

Tumor condroide del cartílago tiroides: reporte de un caso clínico y revisión de la literatura / Chondroid tumor of the thyroid cartilage: case report and literature review

Los tumores condroides de la laringe son poco frecuentes, y generalmente se ubican en el cartílago cricoides. El tratamiento de elección es quirúrgico, con buen pronóstico general. Se presenta el caso de un hombre de 60 años con historia de disfonía. El estudio nasofaringolaringofibroscópico revela una masa laríngea supraglótica. Las imágenes son compatibles con una lesión del cartílago tiroides. La biopsia obtenida por microlaringoscopía directa informa tumor compatible con condroma. Se realiza una resección completa de la masa por abordaje externo, la biopsia corrobora el diagnóstico de tumor condroide de bajo grado. Se describe esta patología mediante revisión bibliográfica.

Chondroid tumors of the larynx are uncommon, and usually located in the cricoid cartilage. Surgery is the treatment of choice, with good prognosis in general. We report the case of a 60-year-old man consulting for dysphonia. The nasopharyngolaryngoscopy showed a supraglottic laryngeal mass. The images were compatible with a thyroid cartilage lesion. The biopsy sample obtained by direct microlaryngoscopy was consistent with a condroma. A complete excision of the lesion was performed by external approach and the biopsy confirmed the diagnosis of a low grade chondroid tumor. We present a review of chondroid tumors of the larynx based on available literature.

Enchondroma of the Hand: Evaluation and Management.

Enchondroma is the most common primary bone tumor of the hand. This benign, cartilaginous tumor often presents as a pathologic fracture. When hand enchondroma is suspected, less common conditions, such as multiple enchondromatosis syndromes and benign and malignant lesions, should be ruled out. Surgical management with curettage is the standard of care for symptomatic lesions. However, controversy surrounds the timing of surgery for pathologic fractures and the use of surgical adjuncts and postcurettage void management. Microscopically distinguishing hand enchondroma from low-grade hand chondrosarcoma is a diagnostic challenge for pathologists, but the primary surgical treatment for both conditions is curettage because the latter has a low metastatic potential. Postoperative complications are typically joint stiffness and soft-tissue[FIGURE DASH]related deformities, whereas recurrence and malignant degeneration of solitary lesions are much less common. Most patients return to full function after surgery.

Chondroma of the Cerebral Falx: Case Report of a Very Rare Intracranial Tumor / Condroma da foice do cérebro: relato de caso de um tumor intracraniano muito raro

Chondromas are a benign cartilaginous tumor that account for approximately 0.5% of primary intracranial tumors. They usually arise from the synchondrosis of the skull base, being rarely reported elsewhere (dura convexity, falx, or even intraparenchymal). Because they are very rare tumors sharing clinical behavior and imagiological similarities with the much more common meningioma, the clinical diagnosis is frequently mistaken after an initial imaging workup. The authors present a case of a 48-year-old woman, with frequent headaches and an extra-axial tumor arising from the anterior falx, initially diagnosed as a meningioma.

Condromas são tumores cartilaginosos benignos que correspondem por aproximadamente 0,5% dos tumores primários intracranianos. Eles geralmente surgem da sincondrose da base do crânio, sendo raramente registrados em outros locais como a convexidade dural, a foice, até mesmo no parênquima cerebral. Por serem tumores muito raros que compartilham comportamento clínico e imagiológico com meningiomas, o diagnóstico é frequentemente confundido após exame de imagem inicial. Os autores apresentam o caso de uma mulher de 48 anos, com cefaleia frequente e um tumor extra-axial ascendendo da foice anterior, inicialmente diagnosticado como um meningioma.

Rehabilitation Management of Hemicorporectomy.

This is a case report of a 55-year-old woman who was treated with a hemicorporectomy consequent to an invasive undifferentiated sacral chordoma. We describe the clinical course and rehabilitation process in an amputee outpatient clinic and report outcome measures such as the modified Functional Reach Test, the Amputee Mobility Predictor, the Functional Independence Measure, and the Short-Form Health Survey after 9 months of rehabilitation.

Simultaneous rupture of the anterior cruciate ligament and a knee tumor.

We report two patients with simultaneous lesions about the knee; a traumatic injury (acute anterior cruciate ligament rupture) and a musculoskeletal tumour; that may be particularly misleading for the treating surgeon.

Condroma de cartilagem cricóide / Chondroma of the cricoid cartilage

Introdução: Os tumores cartilaginosos da laringe são raros, compreendendo 1% de todos os tumores cartilaginosos. O condroma é tumor benigno mais comum acometendo a cartilagem cricóide da laringe (75%), manifestando-se comumente no gênero masculino, com disfonia, dispnéia progressiva e disfagia em alguns casos. Objetivo: O presente estudo tem como objetivo relatar um caso de condroma de cartilagem cricóide, em paciente com sintoma de lesão nodular em região cervical anterior, de crescimento lento e progressivo. Relato do Caso: O tratamento foi a laringectomia parcial modificada, com ressecção do hemisegmento inferior da cartilagem tireóide, hemicartilagem cricóide e primeiro anel traqueal com margens livres e reconstrução com de retalho de pericôndrio e muscular pré-tireoideano. O exame anátomo-patológico demonstrou condroma de 1,1 cm, de baixa celularidade e baixas figuras de mitose atipicamente na região anterior da cartilagem cricóide. Conclusão: Neste relato concordamos com a literatura para o tratamento primariamente cirúrgico, de extensão dependendo da localização e do tamanho do condroma de cricóide, porém outras modalidades de tratamento podem ser adotadas nos casos onde a extensão tumoral indique a laringectomia total ou quando esta não é passível de realização, visando à preservação da laringe. Para o tratamento adequado de condromas de cricóide e entendimento da evolução natural da doença mais relatos de casos ainda são necessários.

Introduction: The larynx cartilaginous tumors are uncommon and comprise 1% of all cartilaginous tumors. The chondroma is the most common benign tumor affecting the larynx cricoid cartilage (75%), and manifests normally in the male gender with dysphonia, progressive dyspnea and dysphagy in some cases. Objective: The objective of this study is to report a case of cricoid cartilage chondroma, in a patient with the symptom of a nodular lesion in the frontal cervical region of slow and progressive growth. Case Report: The treatment was the modified partial laryngectomy with resection of the lower hemisegment of the thyroid cartilage, cricoid hemicartilage and the first tracheal ring with free margins and reconstruction with a pericondrium and muscular prethyroidean piece. The anatomopathological exam showed a chondroma of 1.1 cm, of atypical low cellularity and low figures of mitosis in the frontal region of the cricoid cartilage. Conclusion: In this report we agreed with the literature for the primarily extensive surgical treatment depending on the location and the size of the cricoid chondroma; however, other modalities of treatment may be adopted in cases where the tumor extension appoints a total laryngectomy or when this is not possible to carry out, aiming at the preservation of the larynx. For the suitable treatment of cricoid chondromas, the understanding of the disease natural evolution and more case reports are still necessary.

Condroma de partes blandas / Condroma of soft parts

Se presenta un caso de condroma extra esquelético de pabellón auricular, en un paciente de sexo masculino de 11 años de edad, cuyo inicio fue dos años antes de la consulta en 1999, permaneciendo estable hasta la actualidad. Se consideran los diferentes diagnósticos diferenciales clínicos e histológicos, características evolutivas y el tratamiento del tumor.

Extraosseous vulvar chondroma: a case report.

BACKGROUND: Extraosseous chondromas are cartilaginous tissue tumors with a nodular appearance on the hands and feet. There are reports of these tumors occurring on the knee, neck, back, liver and testis and in the oral cavity. Occurrence in the pelvis is generally rare. The origin is metaplastic and may be mesenchymal or subcelomic. Treatment is by surgery and requires removing the tumor with a safety margin. Recurrences are infrequent, and distant metastasis has never been reported. CASE: An 11-year-old girl was referred for a painless solid tumor located on the mons pubis. Surgical removal of the tumor with a safety margin was performed. Macroscopically, the tumor was shiny when cut open and yellowish. Microscopic examination revealed a very distinct cartilage-forming tumor compatible with extraosseous chondroma. Two years after the operation, the patient had no recurrence. CONCLUSION: Extraosseous chondroma is a rare benign tumor. Finding it in children is even less frequent, and localization in the vulvar region has never before been reported. This appears to be the first such report of this type of tumor in this region and age range.

[Incomplete Carney's Triad and arterial hypertension in a young woman]. / Triada de Carney incompleta e hipertension arterial en una mujer joven.

The case of young woman with arterial hypertension diagnosed two years before, is here presented; she had a ferropenic anemia caused by digestive loss of blood. Multiple gastric tumors and pararenal non functioning paraganglioma were found. No chondromas were detected. An incomplete Carney's Triad was diagnosed. We remark that multiple gastric tumors in a young adult suggest the possibility of gastrointestinal stromal tumors (GIST) Endoscopic biopsy frequently is not effective because these tumors are deep placed in the muscular gastric layers. The importance of specific techniques for a positive diagnosis are emphasized. Continuous follow up is needed because these tumors have uncertain prognosis. Lung chondromas may appear years later after the GIST was removed and might be confused with GIST metastases.

Triada de carney incompleta e hipertension arterial en una mujer joven / Incomplete Carney’s triad and arterial hypertension in a young woman

Se presenta una el caso de paciente joven, con tríada de Carney incompleta que cursa hipertensión arterial de dos años de evolución y anemia ferropénica grave por pérdida crónica de sangre por tubo digestivo, con tumores gástricos múltiples y paraganglioma pararrenal. No presenta aún desarrollo de condromas pulmonares visibles por tomografía axial computada. En nuestra paciente el paraganglioma no resultó funcionante. Resaltamos que la presencia de tumores gástricos múltiples en un adulto joven debe sugerir la posibilidad de tumores estromales (GIST), cuyo diagnóstico por biopsia endoscópica es difícil debido a su localización profunda, situada en las capas musculares de la pared gástrica. Asimismo queremos remarcar la importancia de las técnicas de marcación descriptas para el diagnóstico preciso. El seguimiento debe ser constante dado el pronóstico incierto de estos tumores. Los condromas pulmonares pueden aparecer años después de la resección del GIST y ser confundidos con metástasis del GIST.

Tumores Oseos Condroides: Condromas Versus Condrosarcomas Convencionales

Chondroid lesions present some radiologic features which are common to benign chondroid lesions and chondrosarcomas of low-grade. It is not always possible to differentiate them, and a careful analysis must be looked. We revised the main characteristics of the continuum Enchondroma-Conventional Chondrosarcoma from the perspective of plain X-ray films, Computed Tomography and Magnetic Resonance imaging.

Las lesiones condroides presentan aspectos radiológicos que son comunes para las de carácter benigno y condrosarcomas convencionales de bajo grado. La diferenciación no siempre es posible y se debe considerar una cuidadosa evaluación imagenológica patológica y clínica. Se revisan las principales características imagenológicas del continuo encondroma-condrosarcoma convencional desde la perspectiva de la radiología simple, tomografía computada y resonancia magnética.

Biopsias guiadas por marcación radioisotópica para alteraciones costales solitarias presuntivamente neoplásicas / Radioisotope-guided rib biopsies in suspected neoplastic patients

Antecedentes: El centellograma óseo se usa rutinariamente para estadificación y seguimiento de tumores malignos, especialmente de aquellos que con frecuencia dan origen a metástasis esqueléticas. Anormalidades costales múltiples alejadas de las articulaciones, son generalmente compatibles con metástasis. Pero por otro lado, un sitio solitario de hipercaptación puede no ser debido a la ya conocida enfermedad neoplásica, sino a un proceso benigno coexistente. Para evaluar la significación de este hallazgo, debe llevarse a cabo una biopsia a cielo abierto. Objetivo: Evaluar las biopsias radioguiadas, y la significación de un foco solitario de hipercaptación costal en pacientes neoplásicos o sospechosos de serlo. Lugar de aplicación: Centro oncológico universitario público. Diseño: Retrospectivo. Población: 23 pacientes con lesiones costales solitarias sospechosas de ser neoplásicas primitivas o bien metastásicas de tumores en actividad en algunos casos, o presumiblemente controlados en otros...(AU)
