Summary: Clinical and imaging tests help in the diagnosis and tumor localization. Key Message: Adequate surgical knowledge for these cases ensures lower rates of recurrence and nail dystrophy.

Tumor glómico de la vía aérea y resección carinal, a propósito de un caso

Introducción: describir caso infrecuente de tumor glómico pulmonar que compromete tráquea y bronquio principal derecho con síntomas respiratorios. Los tumores glómicos (GT) de la tráquea son una enfermedad infrecuente, se originan a partir de células musculares lisas modificadas. Los pacientes presentan síntomas inespecíficos como tos, disnea o hemoptisis. Se han reportado tratamientos quirúrgicos, incluyendo toracotomía y resección por fibrobroncoscopia. No hay duda de que la cirugía es el tratamiento de elección, sin embargo, pocos estudios han evaluado el tratamiento ideal para los (GT) traqueales. Caso Clínico: Describimos un caso de (GT) originado en la vía aérea, mujer de 62 años que presentó tos y expectoración durante 7 días, había sido diagnosticada de tumor endotraqueal por tomografía computada. La resección tumoral se intentó mediante broncoscopía, pero presentó bordes positivos, por lo que se realizó resección traqueal quirúrgica y anastomosis. La paciente logró buenos resultados y no se observó recurrencia en un seguimiento de 10 meses. Este es el tercer informe de (GT) originado en vía aérea (tráquea y bronquio principal derecho).

Introduction: Glomus tumors (GTs) of the trachea are a rare soft tissue disease, originating from modified smooth muscle cells. Patients are usually presented with nonspecific symptoms such as cough, dyspnea or hemoptysis. Surgical treatment has been reported, including thoracotomy and bronchoscopic electrocautery, there is no doubt that surgery is the treatment of choice, however few studies have evaluated the ideal treatment for tracheal GTs. Case Report: We describe a case of glomus tumor originated at large airway, a 62-year-old woman who presented with cough, and expectoration for 7 days, had been diagnosed as having a tracheal tumor by thoracic computed tomography. Tumor resection was attempted by fiberoptic bronchoscopy but there were positive edges, therefore surgical tracheal resection and anastomosis were performed. The patient achieved good results and no recurrence was observed during a 10-month follow-up. This is the third report of glomus tumor of the tracheal originated at large airway (trachea and right main bronchus).

The clinicopathologic and immunohistochemical features of 60 cutaneous glomus tumor: a retrospective case series study.

BACKGROUND: Glomus Tumor (GT) are benign neoplasms that originate from mesenchymal cells. It presents as tenderness and cold allodynia in the digits, especially in the subungual region. There are a few studies that investigated the mechanism of pain. OBJECTIVES: To analyze the clinical-pathologic characteristics of GT and to identify the expression of IL-1ß, IL-6, and CGRP in it, further, to explore the possible mechanism of pain. METHODS: The clinical and pathological data of 60 GT patients were retrospectively analyzed. Tissue microarrays and immunohistochemistry were used to measure the expression of IL-1ß, IL-6 and CGRP. RESULTS: GT is more common in females and the ratio of male to was near to 1:2, mostly in middle-aged people. It often occurs in fingertips, especially the thumbs. Patients often present with spontaneous pain, tenderness, and cold hypersensitivity. Both the two pain mediators IL-1ß and IL-6 were highly expressed in GT cells of patients with and without cold hypersensitivity. While CGRP was not expressed in GT. STUDY LIMITATIONS: Low sample size and further research is needed to explore the specific mechanism. CONCLUSIONS: IL-1ß and IL-6 were highly expressed in GT cells, suggesting that IL-1ß and IL-6 have certain nociceptive roles in GT. In the 4 patients with cold intolerance, the intensity of IL-1ß and IL-6 staining was also strong, suggesting that they may not play a role in the cold hypersensitivity. However, since there are only 4 patients with cold intolerance, it's necessary to conduct further in-depth research using a larger sample size. The specific role of CGRP in GT has not been found yet.

High-frequency ultrasonography for subungual glomus tumor evaluation - imaging findings.

OBJECTIVE: This article aimed to describe the common imaging features of subungual glomus tumors. METHODS: The study involved data collected between January 2019 and December 2022. Twenty-three patients with a total of 31 glomus tumors underwent high-frequency ultrasound examinations with a 24-MHz probe. Two experienced radiologists independently evaluated the images, and only data from the more experienced radiologist were used for subsequent analyses. RESULTS: The average size of the tumors was 4.6 mm, and most of them appeared homogeneously hypoechogenic (90.3%). Bone remodeling of the distal phalanx was observed in 87.1% of cases, with an average axial circumference loss of 0.8 mm, indicating the slow and expansive growth of glomus tumors. Intense vascularization was found in 54.8% of cases on Doppler images, and the stalk sign, reflecting the vascular origin of the tumor, was present in 64.5% of cases. The most common clinical feature was pain, reported in 84.6% of cases, with a mean pain scale score of 7.0, indicating a negative impact on patients' lives despite being benign tumors. CONCLUSION: The study concludes that ultrasound evaluation is highly useful for diagnosing glomus tumors, especially when multiple findings, such as bone remodeling, hypervascularization, and the stalk sign, are present. This method allows for accurate diagnosis, observation of periungual structures, and proper surgical planning, ultimately reducing recurrence rates.

Subungual Glomus Tumor of the Hallux A Report of 4 Cases.

This study reports the clinical outcomes and evolution of 4 patients with subungual glomus tumor (GT) of the hallux treated with tumor excision. Preoperatively, all patients had pain of intensity 9 or 10. Three were sensitive to cold and had stabbing pain, and one reported pulsatile pain. No patient presented nail alterations. There were no bone alterations on radiographic images and diagnostic suspicion of GT was supported by magnetic resonance images. Surgical treatment was indicated due to severe pain and functional limitation. The GT excision was performed by removing the nail through an L-shaped incision in the nail bed. After surgery, they all showed clinical improvement with return to previous activities and had no difficulty in wearing regular shoes. Three patients were pain-free and one had occasional stabbing pain of intensity 2. Half of them had nail changes. There has been no recurrence so far. Thus, we found that resection of subungual GT of the hallux was effective for the clinical improvement of patients.Level of Evidence: IV, case reports.

Presentación atípica de tumor glómico en vía aérea: reporte de caso y revisión de literatura / Atypical presentation of glomus tumor in the airway: Case report and literature review

Introducción. Los tumores glómicos provienen de los cuerpos glómicos, que son estructuras con función de termorregulación y se encuentran distribuidas por todo el cuerpo humano, principalmente a nivel distal de las extremidades, donde es común encontrar lesiones características, aunque hay reportes de casos que se presentaron como neoformación en localizaciones más inusuales. Su etiología aun es desconocida. No se sospechan en muchos pacientes y el diagnostico se realiza de manera incidental, por estudios imagenológicos o anatomopatológicos. Caso clínico. Paciente femenina de 66 años, con presencia de tumor glómico en vía aérea, diagnosticado por histopatología e inmunohistoquímica, que fue sometido a resección quirúrgica, con buena evolución posterior. Discusión. Esta presentación atípica de tumor glómico en vía aérea se manifiesta principalmente con síntomas y signos relacionados con obstrucción de la vía aérea. El manejo oportuno es primordial y el diagnóstico definitivo es por histopatología e inmunohistoquímica, donde se observan las características de las células glómicas, estructuras vasculares, músculo liso y la positividad en la inmunotinción de marcadores como actina del músculo liso, CD34, y actina específica del músculo, entre otras. Conclusión. Los tumores glómicos son neoformaciones benignas raras, con presentación más común en zonas distales. Su aparición depende de factores intrínsecos y extrínsecos de los pacientes. Su tasa de recidiva es muy baja en comparación de otros tumores

Introduction. Glomus tumors originate from glomus bodies, which are structures with thermoregulatory function and are distributed throughout the human body, mainly at the distal level of the extremities where it is common to find these characteristic lesions. Although, there are case reports of neoformation presentations with more unusual locations. Their etiology is still unknown. Many times when there is evidence of lesions in atypical areas they are not suspected in many patients and the diagnosis is made incidentally by imaging and/or anatomopathological studies. Clinical case. A 66-year-old female patient with the presence of a glomus tumor in the airway diagnosed by histopathology and immunohistochemistry, underwent surgical resection and presented good evolution after surgery. Discussion. This atypical presentation of glomus tumor in the airway presents mainly with symptoms and signs related to airway obstruction. Timely management is paramount in these patients, and the definitive diagnosis is by histopathology and immunohistochemistry where the presence of the characteristics of glomus cells, vascular structures, smooth muscle and immunostaining positivity towards some markers such as smooth muscle actin, CD34, muscle specific actin, among others, are seen. Conclusion. This type of tumors are rare benign neoformations, with common presentations in distal areas. Their appearance depends on intrinsic and extrinsic factors of the patients and their recurrence rate is very low compared to other tumors

Biomodelling and 3D technologies: A novel technique for subungual glomus tumor evaluation.

Subungual glomus tumors often remain undiagnosed for several years with patients seeing an average of 2.5 dermatologists before the diagnosis is confirmed. We describe the use of biomodelling and 3D technologies that allows the detection of tumoral recurrences more easily, as well as providing supplementary information for the radiologist report, such as select anatomical structure analysis, images with 360° rotation and visualization in transparency mode for detailed anatomic analysis.

Juxtaglomerular cell tumor: report of a case with unusual presentation.

Juxtaglomerular cell tumor is a benign, renin-secreting neoplasm. The tumor arises from the juxtaglomerular apparatus cells of the kidney. Because the tumor is hormonally active, patients usually suffer from hypokalemia, hyperaldosteronism, and hypertension. Herein, we describe a case of a 19-year-old Asian female with a somewhat unusual presentation. A 19-year-old Asian female presented with upper extremity weakness, numbness, and tingling. On physical examination, the only notable finding was hypertension. Extensive workup revealed elevated aldosterone level and plasma renin activity. CT scan of the abdomen revealed a 2.2 cm mass in the lower pole of the left kidney. The mass was resected by partial nephrectomy. On microscopic evaluation, the tumor had glomoid appearance with sheets of uniform, round to polygonal cells with clear to eosinophilic cytoplasm. Immunohistochemical stains showed the tumor cells to be positive for CD117, CD34 and CD10 and negative for ER, PR, CK7, PAX-8, pan-cytokeratin, EMA, S100, Melan-A, HMB45, SMA and CAIX. Diagnosis of Juxtaglomerular cell tumor was rendered. This case highlights the importance of a regular physical exam and a high index of suspicion in patients presenting with unusual complaints.

Resumen Los paragangliomas (cuerpo carotideo) son tumores benignos de alta vascularización ubicados en la región de los quimiorreceptores del cuerpo carotideo. Respecto a su localización, el glomus carotídeo, es del 0,01% en relación a los otros tumores de tipo paranganglioma, se observa con mayor incidencia en habitantes de lugares de altitud, más frecuente en sexo femenino. Clínicamente se presenta como una tumoración en región cervical de progresivo crecimiento, indoloro y con frémito. Dentro de los exámenes de gabinete auxiliares para diagnóstico, estan: la Ecografia Doppler, la Tomografía Axial Computarizada, la Resonancia Magnética y la Arteriografía. La técnica quirúrgica más frecuente para abordar este tumor es la disección subadventicial. Presentamos el caso clínico de una mujer de 57 años con tumor cervical, que fue intervenida quirúrgicamente, previo exámenes de laboratorio y gabinete, para la resección total del tumor y posterior estudio anatomo-patológico que reportó: paraganglioma de cuerpo carotideo.

Abstract Paragangliomas (carotid body) are benign tumors with high vascularization located in the region of the carotid body chemoreceptors. Regarding its location, the carotid glomus is 0.01% in relation to other paranganglioma type tumors, it is observed with higher incidence in high altitude populations, more frequent in females. Clinically it presents as a tumor in the cervical region of progressive growth, painless and with fremitus. Among the auxiliary tests for diagnosis are: Doppler Ultrasound, Computerized Axial Tomography, Magnetic Resonance Imaging and Arteriography. The most frequent surgical technique to address this tumor is subadventitial dissection. We present the clinical case of a 57-year-old woman with a cervical mass, who underwent surgery, after preliminary laboratory tests, for total resection with subsequent anatomo-pathological study that reported: paraganglioma of the carotid body.

Extradigital glomus tumor: dermoscopic description and histopathological correlation

Abstract Glomus tumors are rare benign neoplasms arising from the neuromyoarterial structure called glomus body. They present as angiomatous papules, soft and painful, especially to cold and pressure. In general, they are solitary and affect the extremities, located mainly the subungual bed. Extradigital lesions are rare and can constitute a diagnostic challenge. This is the report of a patient with an extradigital lesion on the left arm, and its dermoscopic aspects, including angiomatous lagoons circumscribed by a pale halo, a structure not previously described in the two reports of extradigital glomus tumor with dermoscopic features, found in the literature.

Tumores gástricos peculiares: tumor glómico, schwannoma, leiomioma y cistoadenoma en el páncreas ectópico. Serie de casos y revisión de la literatura / Unusual gastric tumors: Glomus tumor, schwannoma, leiomyoma, and cystadenoma in ectopic pancreas. A case report and literature review

Resumen Introducción: la patología gástrica es excepcionalmente benigna, se registra a nivel mundial un porcentaje de aparición de las mismas del 0,005 %-4 %. Además de lo anterior, suele plantearse como primer diagnóstico diferencial un carcinoma gástrico, por lo que la mayoría de los pacientes termina en un procedimiento quirúrgico mayor. El objetivo de este estudio fue describir una serie de casos registrados en una institución de alta complejidad, así como la revisión de la literatura al respecto del tema. Pacientes y métodos: se realizó la revisión de las bases de datos del servicio de cirugía general de la Clínica Universitaria Colombia y se encontraron 4 tumores gástricos de presentación inusual, de los cuales se hizo revisión de la historia clínica y las imágenes disponibles (diagnósticas y de las piezas de cirugía). Resultados: en la revisión de la base de datos, se encontraron 4 casos, 2 de sexo femenino y 2 de sexo masculino, con una media de edad de 51 años (26-75 años). El 100 % de los pacientes tenía una lesión en la región antral y solo uno de ellos tenía una segunda lesión a nivel prepilórico. La totalidad de los pacientes fue llevada a gastrectomía subtotal con reconstrucción en Y de Roux por abordaje laparoscópico y la media de estancia hospitalaria fue de 3,5 días (2-6 días). Conclusión: para determinar la mejor opción de tratamiento en general en pacientes con lesiones gástricas siempre hay que considerar tanto las características endoscópicas y endosonográficas como las histológicas.

Abstract Introduction: Gastric pathology is exceptionally benign with a percentage of appearance between 0.005% - 4% worldwide. Moreover, gastric carcinoma is often suggested as the first differential diagnosis and for that reason, the outcome for a vast majority of admitted patients is a major surgical procedure. This study aims to describe a series of cases recorded in a high complexity medical institution and to carry out a literature review related to that subject. Patients and Methods: Databases from the general surgery service of the Clínica Universitaria Colombia were reviewed, and four unusual gastric tumors were found. A review of the related medical records and available images (diagnostic images and surgical elements) was performed. Results: After the database review, four cases were found: two female cases and two male cases, with a mean age of 51 years (26-75 years). All the patients had lesions in the antrum area and only one of them has an additional lesion in the prepyloric region. All patients were treated with a laparoscopic subtotal gastrectomy with Roux-en-Y reconstruction and the mean length of hospital stay was 3.5 days (2-6 days). Conclusion: It is required to consider the endoscopic, endosonographic, and histological examinations and their features to determine the best treatment for patients with gastric lesions.
