Foreign Body Granuloma Originating From the Lateral Process of Malleus: A Case Series of 19 Children.

OBJECTIVE: A special presentation of foreign body granuloma originating from the lateral process of the malleus (FBGLP) was noted in the absence of a history of foreign body entry into the external auditory canal (EAC). This study reported the clinical features, pathology, and prognosis of patients with FBGLP. DESIGN: Retrospective study. SETTING: Shandong Provincial ENT Hospital. PATIENTS: Nineteen pediatric patients (age, 1-10 yr) with FBGLP. INTERVENTIONS: Clinical data were collected from January 2018 to January 2022. MAIN OUTCOME MEASURES: Clinicopathologic characteristics of the patients were analyzed. RESULTS: All patients had an acute course, and were within 3 months of ineffective medical treatment. The most common symptoms were suppurative (57.9%) and hemorrhagic (42.1%) otorrhea. FBGLP imaging examinations demonstrated a soft mass blocking the EAC without bone destruction and occasionally concomitant effusion in the middle ear. The most common pathologic findings were foreign body granuloma (94.7%,18/19), granulation tissue (73.7%, 14/19), keratotic precipitate (73.7%, 14/19), calcium deposition (63.2%, 12/19), hair shafts (47.4%, 9/19), cholesterol crystals (5, 26.3%), and hemosiderin (15.8%, 3/19). Foreign body granuloma and granulation tissue showed higher expression levels of CD68 and cleaved caspase-3 than did the normal tympanic mucosa, whereas Ki-67 levels were similarly low in all tissues. The patients were followed up for 3 months to 4 years without recurrence. CONCLUSION: FBGLP is caused by endogenous foreign particles in the ear. We recommend the trans-external auditory meatus approach for FBGLP surgical excision, as this shows promising outcomes.

Microblading-Induced Granulomatous Reaction: Case Report and Review of the Literature.

ABSTRACT: Microblading is a common cosmetic procedure that can modify the appearance of one's eyebrows. Although generally well-tolerated, the procedure can cause a number of dermatologic issues; on rare occasions, granulomatous reactions can manifest. We use this case to highlight a presentation of a nonsarcoidal granulomatous dermatitis and review the literature on granulomatous reactions secondary to microblading. Of the 21 cases included in our review, approximately half (10/21) were diagnosed with foreign-body granulomas and the other half with sarcoidosis (7 of 21 with systemic sarcoidosis and 4 of 21 with cutaneous sarcoidosis). Although microblading remains a commonplace cosmetic technique, it is not without risk. Much like other types of tattoos, microblading can cause granulomatous reactions for which we must be vigilant, and further workup for sarcoidosis might be considered in select patients.

Pulse Granuloma-Like Reaction on the Forearm Following an Accidental Wound.

ABSTRACT: Pulse granulomas are uncommon reactions to vegetable exogenous matter characterized by the presence of hyaline rings. Although they are usually found in the oral cavity or along the gastrointestinal or respiratory tracts, there are a few cases described outside those regions. We present the first case of a granulomatous reaction with hyaline rings in the skin reaction after an accidental wound and suggest the term pulse granuloma-like to describe lesions that resemble pulse granulomas but with no connection to the gastrointestinal or respiratory tracts. Moreover, we provide a graphic comparison of the hyaline rings observed in our case and the histologic sections of some plants that could have been involved.

Endoscopic Removal of Huge Cholesterol Granuloma in the Maxillary Sinus Confused With Odontogenic Keratocyst.

Cholesterol granuloma is a foreign body reaction to the deposition of cholesterol crystals, usually found in association to chronic middle ear diseases, being highly uncommon in the paranasal sinuses. Furthermore, a huge and aggressive cholesterol granuloma involving the maxillary sinus, hard palate, buccal space, and maxillary alveolus is extremely rare and has not been reported previously. This article reports a case of huge cholesterol granuloma in the maxillary sinus confused with an expansile odontogenic keratocyst, which was treated successfully via transnasal endoscopic approach.

Oral pulse granuloma and oral pulse granuloma associated with odontogenic keratocyst: Two clinical cases and a review of the literature.

Two cases of oral pulse granuloma (OPG) or vegetable granuloma (VG) are presented, one of which was concomitant with an odontogenic keratocyst (OKC), which is an unusual finding. OKC is characterized by the presence of hyaline rings which include vessels, giant cells, other inflammatory cells and collagen fibres. There are two hypotheses as to its histogenesis: firstly, as a reaction to vegetable matter, such as legumes (thus the nomenclature "pulse" or edible seed) and secondly as a degenerative change in the vessel walls as a result of localized vasculitis. Due to the deceptive appearance of OPG, diagnosis can be challenging.

Cholesterol Granulomas: A Comparative Meta-Analysis of Endonasal Endoscopic versus Open Approaches to the Petrous Apex.

Petrous apex cholesterol granulomas (PACG) are rare disorders that can lead to patient morbidity and must, occasionally, be drained by either endoscopic endonasal (EN) or open procedures (OP). The objective of our study was to complete a review of the literature to compare the EN and OP approaches on multiple levels, notably on safety and effectiveness. Ovid MEDLINE and Embase were used to perform a thorough literature review of all cases of PACG treated by either EN or OP dating from January 1948 to August 2017. In total, 49 articles were selected including 23 for EN (n=76) and 26 for OP (n=210). Differences were found in the incidence of preoperative hearing loss (HL) (EN 18.4%, OP 57.3%; p<0.001), headache (EN 48.7%, OP 31.2%; p=0.007), and disequilibrium (EN: 14.5%, OP 26.1%; p=0.04). Differences in lesion proximity to the sphenoid sinus (EN 23.6%, OP: 1.0%; p<0.001), clivus (EN 11.8%, OP 4.7%; p=0.03), otic capsule (EN 0.0%, OP 5.2%; p=0.03), internal auditory canal (EN 2.6%, OP 10.9%; p=0.01), and internal carotid artery (ICA) (EN 9.2%, OP 2.8%; p=0.02) were found on preoperative imaging. The EN procedure had better hearing improvement rates (EN 85.7%, OP 23.4%; p<0.001), lower complication rates (EN 7.9%, OP 17.6%; p=0.04), shorter median follow-up (EN:13.5 months, OP:37.2 months; p<0.001), and shorter time to recurrence (EN 3 months, OP 22.6 months; p=0.002) than the known OP. No differences were found in age, preoperative size, recurrence rate, operative time, stent placement, or improvement of other symptoms. Endoscopic nasal approaches, when feasible, should be favored to open procedures for PACG drainage given their better hearing improvement and less complication rates.

Cochlear Implant Electrode Migration due to Cholesterol Granuloma: Cues from a Case.

This paper aims to describe a rare case of cochlear implant (CI) failure due to electrode array migration and review the literature on the topic. A 72-year-old woman complained of retroauricolar pain two years after receiving a left CI, with deterioration of the auditory skills and an increased impedance of electrodes. Temporal bone computed tomographic scans revealed a soft density tissue involving the left mastoid and the middle ear. It also revealed a lateral displacement of the array into the middle ear. Surgery with CI re-implantation was performed. The specimen examination disclosed the presence of a cholesterol granuloma. According to the literature, array migration after CI due to cholesterol granuloma is very rare. When patient's auditory performances decline and electrodes impedance increases, computed tomography (CT) scans should be performed to detect possible electrode issues, as in this case. Middle ear and mastoid cholesterol granuloma represent a possible, rare, cause of electrode array migration, even in absence of cochlear erosions.

Complete Recovery of Sensorineural Hearing Loss Following Endoscopic Transsphenoidal Surgery for a Petrous Apex Cholesterol Granuloma: Case Report.

BACKGROUND Cholesterol granulomas of the petrous apex may impinge surrounding cranial nerves, leading to neurological impairments such as hearing loss. Less invasive endoscopic techniques are gaining popularity as the mainstay of therapy for this lesion. CASE REPORT We present a case of petrous apex cholesterol granuloma causing mild sensorineural hearing loss. An endoscopic endonasal transsphenoidal approach was successfully performed to partially resect and aerate the lesion. The auditory function on the affected side was completely restored after surgery. The patient experienced no post-operative complications. CONCLUSIONS This case report highlights the advantages of using an endoscopic transsphenoidal surgical approach in cases of petrous apex cholesterol granuloma, including the potential for this less invasive technique to restore sensorineural hearing loss.

Diagnosis and management of hypercalcemia associated with silicone-induced granuloma.

Hypercalcemia associated with silicone-induced granuloma is a rare disease. Diagnosis can be tricky as it is established after ruling out other hypercalcemia-causing entities. In addition, management is customized depending on the patient's wishes and possible solutions. We present a male bodybuilder, in his thirties, with multiple silicone injections in his upper extremities, who developed hypercalcemia and urinary symptoms. Advanced laboratory tests ruled out various causes of hypercalcemia and CT imaging revealed nephrocalcinosis. A biopsy of the upper arm showed granulomatous tissue and inflammation. The patient necessitated two sessions of dialysis and corticosteroids were given to relieve symptoms and reverse laboratory abnormalities. Silicone-induced hypercalcemia should be on high alert because of the increasing trend of body contour enhancements with injections, implants and fillers. Treatment should be optimized depending on the patient's needs and condition.

Muslin Granuloma Mimicking Parenchymal Hematoma in Patient with Seizures 30 Years After Aneurysm Wrapping.

Muslin foreign body granulomas are a known complication of muslin aneurysm wrapping and have been associated with vision loss from optochiasmatic arachnoiditis. Muslin granulomas have also been confused with abscesses due to surrounding inflammatory changes. In this clinical image, we present a unique case of a muslin granuloma mimicking an intraparenchymal hematoma.

RESUMO A hipercalcemia associada ao granuloma induzido por silicone é uma doença rara. O diagnóstico pode ser complicado, pois é estabelecido depois de eliminadas outras entidades que causam hipercalcemia. Além disso, o gerenciamento é personalizado, dependendo dos desejos do paciente e das possíveis soluções. Apresentamos um fisiculturista masculino, com trinta e poucos anos, múltiplas injeções de silicone nas extremidades superiores, que desenvolveu hipercalcemia e sintomas urinários. Testes laboratoriais avançados descartaram várias causas de hipercalcemia e a imagem da TC revelou nefrocalcinoses. Uma biópsia da parte superior mostrou tecido granulomatoso e inflamação. O paciente exigiu duas sessões de diálise e foram administrados corticosteroides para aliviar os sintomas e reverter as anormalidades laboratoriais. A hipercalcemia induzida por silicone deve estar em alerta elevado devido à crescente tendência de aprimoramentos do contorno corporal com injeções, implantes e enchimentos. O tratamento deve ser otimizado de acordo com as necessidades e condições do paciente.

[Post-traumatic pulmonary aspergilloma]. / Aspergillome pulmonaire sur corps étranger résiduel post-traumatique. Diagnostic et prise en charge.

INTRODUCTION: Aspergillomas occur due to colonization of a pre-existing pulmonary, bronchial or pleural cavity by Aspergillus spp. Often asymptomatic, this pathology can reveal itself by recurrent haemoptysis or when bacterial superinfections occur. Aspergillomas occurring in post-traumatic cavities are rare and their management is poorly codified. CASE REPORT: A child suffered from a chest wound at the age of 13 years. Two years later, investigation of recurrent haemoptysis revealed a residual pneumatocele in the right lower lobe colonized by Aspergillus spp. Initial treatment with systemic azole antifungals was unsuccessful because of digestive and ophthalmological intolerance. Surgical treatment by right lower lobectomy was finally decided on by the multidisciplinary team. This revealed an intrabronchial foreign body of vegetal type with cellulosic reinforcement, causing a polymorphic granulomatous reaction around, and associated with a proliferation of filamentous fungi including Aspergillus fumigatus. Surgery was followed by liposomal amphotericin B treatment for three weeks with a favourable outcome. CONCLUSIONS: This clinical case illustrates the benefits of surgical management of post-traumatic aspergillomas, even in children, in order to eradicate the aspergillus implant and to remove any foreign body to prevent recurrence.

Surgical Management of Penile Lesions Secondary to Foreign Body Reaction: A Case Report and Systematic Review.

BACKGROUND: To improve the penile contour, some men choose to undergo implantation or injection of nonbiological materials. Foreign body reactions in penile tissue may produce scarring, deformity, ulceration, necrosis, and even gangrene. Consensus is lacking regarding the most effective surgical procedure for reconstruction of these penile lesions. OBJECTIVES: The authors describe one case study and the first systematic review focusing on reconstructive surgical management for penile lesions secondary to foreign body reaction. METHODS: PubMed, Medline, and Cochrane databases were queried for publications written in English, French, Portuguese, and Spanish from 1951 to May 2017. Multiple search terms were applied. RESULTS: Of the 3304 articles identified, 51 were included in the systematic review. All were retrospective studies, case series, or case reports. A total of 260 patients underwent surgical procedures, and the complication rate was 37.3%. The scrotal flap technique was performed most frequently (43.4%) and resulted in 65.6% of the total complications observed. One Brazilian case study was also described with an extensive and circumferential ulcer after six mineral oil bolls implant in the penile subcutaneous tissue. CONCLUSIONS: Restoration of the penile shape preserving the functionality and maintaining a good physician-patient relationship may be a challenge. The scrotal pouch may be advantageous for patch grafting of penile soft-tissue lesions, owing to its skin laxity and good blood supply. A less aggressive surgical approach has the benefits of shorter healing time and fewer early complications. Penile injuries are best treated by experienced surgeons on a case-by-case basis with care given to identify the most appropriate treatment.

Transsphenoidal and infralabyrinthine approach of the petrous apex cholesterol granuloma.

Space-demanding or destructive changes in the petrous bone are often challenging differential diagnosis. Cholesterol granulomas of the petrous apex can clinically present in a combination of hearing loss, vertigo, tinnitus, chronic cephalgia, impairment of facial nerve function, neuralgic pain of the nervus trigeminus, or manifest diplopia by the nerve palsy of the nervus abducens. CT-morphologically cholesterol granulomas appear as soft-tissue density masses, which may display a discrete rim after intravenous administration of a contrast agent. The MRI, T1 as well as T2-weighted images show a strong signal in the area of the lesion. Depending on the individual anatomical conditions, the surgical access must be carefully chosen between transsphenoidal, transtemporal, infracochlear/-labyrinthine, or translabyrinthine. Here, we present the transsphenoidal and translabyrinthine access for the excision of cholesterol granulomas of the petrous apex. The different accesses are compared using a neuro-navigation-supported surgical technique with respect to its complications, drainage possibilities, outcomes, and recurrence of symptoms.

B Cell Lymphoma Underlying Paraffinoma of Glabella.

Soft tissue reactions to paraffin include inflammation, fibrosis, disfigurement, and granulomatous inflammation with foreign body giant cell reaction. The authors report the case of a 77-year-old woman with cutaneous marginal zone B cell lymphoma located on glabella, arising in association with underlying paraffinoma. While it is unclear whether the implant directly contributed to the development of lymphoma, this association has not been previously documented, prompting this report.
