The pathological findings are characterized by the presence of foreign body granulomas with a sarcoid-like reaction. Its Interpretation Is difficult given Its association with sarcoidosis. We report the clinical case of a female patient with granulomatous lesions In reaction to a foreign body secondary to the multiple application of unknown substances on the face and buttocks.

Delayed Granulomas after Filler Injection in an Immunosuppressed Patient: A Case Report

Recently, dermal fillers have been used with increasing frequency to improve facial contours for cosmetic purposes. The appreciable increase in such filler procedures has led to more adverse events and complications. Herein, we report the clinical significance and differential diagnosis of delayed multiple granulomas that occurred in a patient with a history of an injection of an unknown substance as a filler 20 years previously. She was also taking oral steroids and tacrolimus for immune suppression after a kidney transplant that she received 10 years before she presented with granulomas.

Diagnostic value of integrated ¹⁸F-fluoro-2-deoxyglucose positron emission tomography/computed tomography in recurrent epithelial ovarian cancer: accuracy of patient selection for secondary cytoreduction in 134 patients / 부인종양

OBJECTIVE: The aim of this study was to evaluate the diagnostic value of integrated 18F-fluoro-2-deoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) for suspected recurrence of epithelial ovarian cancer (EOC) with non-disseminated lesions. METHODS: We retrospectively reviewed the medical records of recurrent EOC patients who underwent secondary cytoreduction from January 2000 to December 2013. A total of 134 patients underwent secondary cytoreduction after imaging with either 18F-FDG-PET/CT or contrast-enhanced computed tomography (CECT). RESULTS: In a patient-based analysis of 134 patients, 124 (92.5%) were confirmed to be positive for malignancy. Among 72 patients with suspected non-disseminated recurrence on 18F-FDG-PET/CT, 65 (89.0%) were confirmed to have recurrence, giving 98.5% sensitivity, 87.7% accuracy, and 88.9% positive predictive value (PPV). In the 65 patients with recurrence, residual tumor remained in 14 patients, giving an accuracy of patient selection for secondary cytoreduction of 69.4% (50/72) and it is higher than that of CECT (64.0%). In 169 lesions removed from patients who underwent preoperative 18F-FDG-PET/CT, 135 (79.9%) were confirmed to be positive for malignancy and 124 were accurately detected by 18F-FDG-PET/CT, giving 91.9% sensitivity, 81.1% accuracy, and 85.5% PPV. Foreign body granuloma was found in 33.3% of 21 lesions with false-positive 18F-FDG-PET/CT findings (7/21). The mean preoperative cancer antigen 125 (CA-125) level in false-positive patients was 28.8 U/mL. CONCLUSION: Compared with CECT, 18F-FDG-PET/CT shows higher sensitivity in lesion-based analysis and better accuracy of patient selection for secondary cytoreduction. However, there is still a need for integration of the results of 18F-FDG-PET/CT, CECT, and CA-125 levels to aid treatment planning.

Pencil-core granuloma

Abstract: Pencil core granulomas are still infrequently reported in the literature. A 67-year-old woman presented with a 4mm hard blue subcutaneous nodule on the forehead. She remembered being injured with a pencil tip about 60 years before. The subcutaneous nodule was excised, which microscopically revealed a foreign body reaction with histiocytes containing fragmented coarse black particles. We diagnosed pencil-core granuloma based on the patient's history of pencil tip injury and histological examination findings.

Pulmonary foreign body granulomatosis in a chronic user of powder cocaine / Granulomatose pulmonar de corpo estranho em um usuário crônico de cocaína em pó

ABSTRACT We describe the case of a 33-year-old man, a chronic user of powder cocaine, who presented with dyspnea, fever, night sweats, and significant weight loss. Chest HRCT revealed centrilobular nodules, giving an initial impression of miliary tuberculosis. Therefore, he was started on an empirical, four-drug antituberculosis treatment regimen. Four weeks later, despite the tuberculosis treatment, he continued to have the same symptoms. We then performed transbronchial lung biopsy. Histopathological analysis of the biopsy sample revealed birefringent foreign body granuloma. A corroborative history of cocaine snorting, the presence of centrilobular nodules, and the foreign body-related histopathological findings led to a diagnosis of pulmonary foreign body granulomatosis. This report underscores the fact that pulmonary foreign body granulomatosis should be included in the differential diagnosis of clinical profiles resembling tuberculosis.

RESUMO Descrevemos o caso de um homem de 33 anos de idade, usuário crônico de cocaína em pó, que apresentava dispneia, febre, sudorese noturna e perda de peso significativa. A TCAR de tórax revelou nódulos centrolobulares, dando uma impressão inicial de tuberculose miliar. Por isso, o paciente passou a receber tratamento empírico com quatro tuberculostáticos. Quatro semanas depois, apesar do tratamento antituberculose, o paciente continuou a apresentar os mesmos sintomas. Foi então realizada a biópsia pulmonar transbrônquica. A análise histopatológica da amostra obtida revelou granuloma de corpo estranho birrefringente. A história de uso de cocaína por inalação, a presença de nódulos centrolobulares e os achados histopatológicos de corpos estranhos confirmaram o diagnóstico de granulomatose pulmonar de corpo estranho. Este relato destaca o fato de que a granulomatose pulmonar de corpo estranho deve ser incluída no diagnóstico diferencial de perfis clínicos que se assemelham a tuberculose.

Necrose de parafinoma peniano após injeção de óleo mineral por profissional não médico / Penile paraffinoma necrosis after mineral oil injection applied by a non-medical professional

Parafinoma decorre da implantação de óleo mineral na pele, sendo caracterizado por reação inflamatória do tipo corpo estranho com período de latência variável. As lesões iniciais são nódulos endurecidos, que podem ulcerar, fistulizar ou necrosar. Esta técnica foi muito utilizada para fins estéticos no século XX, não sendo mais realizada por médicos. Contudo, ainda é empregada por profissionais não médicos ou pelos próprios pacientes, principalmente na região genital, para melhoria da prática sexual. Relata-se caso de implante de óleo mineral no pênis, realizado por profissional não médico para fins estéticos, que evoluiu com necrose após três anos.

Paraffinoma results from the implantation of mineral oil in the skin, being characterized by inflammatory reaction of foreign body type, with variable latency period. Initial lesions consist of hardened nodules, which can ulcerate, fistulate or necrose. This technique was widely used for aesthetic purposes in the 20th century, and is no longer performed by physicians. However, it is still used by non-medical professionals or by the patients themselves, mainly in the genital region, aimed at improving sexual activity. This paper reports a case of implantation of mineral oil in the penis, performed by a non-medical professional, for aesthetic purposes that evolved with necrosis after three years.

Magnetic resonance imaging appearance of foreign-body granulomatous reactions to dermal cosmetic fillers

Foreign Body Granulomas after the Use of Dermal Fillers: Pathophysiology, Clinical Appearance, Histologic Features, and Treatment

A foreign body granuloma is a non-allergic chronic inflammatory reaction that is mainly composed of multinucleated giant cells. Foreign body granulomas may occur after the administration of any dermal filler. Factors such as the volume of the injection, impurities present in the fillers, and the physical properties of fillers affect granuloma formation. The formation of granulomas involves five phases: protein adsorption, macrophage adhesion, macrophage fusion, and crosstalk. The clinical and pathologic features of granulomas vary depending on the type of filler that causes them. Foreign body granulomas can be treated effectively with intralesional corticosteroid injections. Surgical excisions of granulomas tend to be incomplete because granulomas have ill-defined borders and moreover, surgical excisions may leave scars and deformities.

Penile Augmentation with Resultant Foreign Material Granuloma and Sequalae

Throughout history, a proportion of men appear to correlate penis size and dimensions directly with physical fitness and sexual prowess. Foreign materials, such as paraffin oil, paraffin balm, mineral oils, and silicone, have been used to promise an improvement in penile shaft contour and dimensions. These materials are injected directly into the penis; inducing granuloma formation to achieve increased penis length and girth. However, the result is a severely disfigured and swollen penis, which cannot achieve erection. Local complications of penile lipogranuloma include infection, ulceration, local migration, and cavernosal invasion; leading to functional impairment. Meanwhile, systemic complications include foreign body embolization, organ infarct, and death. Penile lipogranuloma is best treated surgically. Granulomatous skin needs to be completely excised; wound closure with a scrotal skin flap, Cecil’s inlay operation and split thickness skin graft commonly used options. Our case series has shown that penile lipogranuloma, induced by subcutaneous foreign body injections into the penile shaft, and its subsequent adverse outcomes to patients and their partners.

Se considera como cuerpo extraño a cualquier objeto, material o sustancia, que por accidente o de manera voluntaria llegue del exterior a invadir nuestro organismo, pudiendo o no alterar cualquiera de las funciones de este. Los cuerpos extraños llegan a localizarse en cualquier nivel de nuestro cuerpo, siendo los sitios de mayor predisposición las cavidades naturales tales como oídos, boca, nariz, así como también en piel, mucosa, sistema respiratorio, sistema digestivo. Los tipos de materiales que con mayor frecuencia encontramos como cuerpos extraños son los huesos de animales, vidrio, materiales sintéticos, elementos metálicos tales como monedas o baterías. El tratamiento que se le dé a estos depende de la localización y el efecto que esté produciendo. Se presenta el caso clínico de un paciente que de manera fortuita se observó la presencia de un cuerpo extraño a nivel de mucosa labial inferior. El cual se diagnosticó gracias a una buena realización de la historia clínica y a la utilización de ayudas diagnosticas necesarias para establecer la presencia del cuerpo extraño y dar el tratamiento adecuado.

Any object, material, or substance which accidentally or voluntarily enters from outside and invades the organism, is considered a foreign object, and which is capable or not of altering any of the body functions. Foreign objects can enter any part of the body, with the natural cavities such as ears, mouth, and nose being the most commonly affected. Other areas affected are skin, mucosa, respiratory track and digestive system. The materials most commonly found as foreign objects are animal bones, glass, synthetic materials, and metallic elements such as coins or batteries. The treatment provided to these problems depends on the location and the effect being produced. A clinical case of a patient who accidentally observed the presence of a foreign body in the labial mucosa of the lower lip is presented.
