A case of oral foreign-body granuloma due to diatoms.

Diatoms are photosynthetic algae with a siliceous exoskeleton. Diatoms are utilized by a wide array of industries for applications such as filtration and pest control. Unsubstantiated claims have also propelled their societal reach to trendy oral and topical uses. This case highlights a rare case of an oral granuloma secondary to diatoms. An 80-year-old woman presented with a mobile, firm, asymptomatic submucosal mass on her lower left mandibular vestibular mucosa. Histopathology showed a non-caseating granulomatous reaction to diatoms. Her only verified contact with a diatomaceous earth product was a dental impression using alginate after upper front teeth trauma 5 months before. Although there have been several cases of allergic contact dermatitis attributed to diatoms, there are no reported cases of diatom-induced granuloma formation found in the literature. There are, however, ample data on granulomas initiated by silica. Given the silica-based composition of diatoms, and the broad use of diatoms in industry and alternative medicine, it is unclear why diatom-induced granulomas are not more widely described. This report may alert clinicians to the existence of diatom granulomas and incline them to tailor their history to cover questions about possible exposure when evaluating patients presenting with a localized oral lesion.

A case of foreign body granuloma caused by 'Bong-chim' at the site of postherpetic neuralgia.

Foreign body granuloma is a potential adverse effect of acupuncture and usually occurs as an inflammatory reaction to foreign bodies that are accidentally or intentionally injected. This case presents a foreign body granuloma caused by honeybee acupuncture at the site of postherpetic neuralgia and highlights the need for caution and awareness of the side effects of acupuncture-related procedures.

Diagnose of occult bronchial foreign body: A rare case report of undetected Chinese medicine aspiration for 10 long years.

BACKGROUND: Occult bronchial foreign body can be very difficult to diagnose early in an adult patient without acute symptoms. This report describes a rare case of undetected Chinese medicine "Coptis chinensis" aspiration for 10 long years. METHODS: A case was reported that a female patient complained of a 10-year history of productive cough. A battery of tests were given to confirm the diagnosis. RESULTS: Chest computed tomography (CT) showed extensive bronchiectasis and multiple nodules, along with stenosis of left lower lobar bronchus. An extensive solid lesion with surrounding inflammatory granulation tissue was seen on her first bronchoscopy and biopsy revealed chronic mucosal inflammation. A neglected history of Coptis chinensis regularly kept in-mouth while sleeping for the last 10 years in this patient provided clues for a final diagnosis. Confirmatory diagnosis of bilateral tracheobronchial foreign bodies caused by recurrent inhalation of Coptis chinensis was made by a second bronchoscopy. CONCLUSIONS: This case clearly demonstrates that a precise medical history is often overlooked. A high index of suspicion, a precise medical history, radiographic features of chronic respiratory symptoms not explained by other conditions were keys to diagnosing this case.

Neglected foreign body aspiration mimicking bronchial carcinoma.

Foreign body aspiration can occur in any age group, but it is more commonly seen in children. In adults, there is usually a predisposing condition that poses a risk of aspiration. If aspiration occurs, prompt diagnosis and extraction of the foreign body is needed to prevent early and late complications. We report a rare case of neglected foreign body aspiration in a 45-year-old schizophrenic opium addicted patient, which resulted in an occlusive lesion in the bronchus, mimicking bronchial carcinoma.

Abdominal Subcutaneous Mass After Laser-Assisted Lipolysis and Immediate Multiple Treatments with a Dual-Wavelength Laser, Vacuum and Massage Device.

UNLABELLED: Body contouring by means of minimally invasive procedures is a growing trend. Current approaches to body contouring often involve a combination of surgical techniques (eg, laser-assisted liposuction) and a series of noninvasive device-based treatments aimed at accelerating recovery and improving aesthetic outcomes. In this case study, we describe a 38-year-old woman who presented with an abdominal-wall mass that resembled a tumor when assessed with magnetic resonance imaging. Twenty-six months before presenting to our office, the patient had undergone laser lipolysis and a series of treatments with a device that delivered dual-wavelength laser energy and vacuum-assisted massage. To address the patient's concerns, we removed the mass and performed abdominal dermolipectomy. No postoperative complications occurred, and the patient was highly satisfied with the aesthetic outcome. The results of histologic studies indicated that the mass was pseudocystic and fluid-filled, surrounded by a fibrous capsule, and characterized as a foreign-body granuloma. Further analysis is warranted regarding the safety of laser lipolysis without aspiration combined with a device delivering dual-wavelength laser energy and vacuum-assisted massage. LEVEL OF EVIDENCE: 5 Risk.

Calcium hydroxylapatite nodule resolution after fractional carbon dioxide laser therapy.

BACKGROUND: Injection of calcium hydroxylapatite filler may result in nodule formation owing to superficial placement of the filler. Calcium hydroxylapatite nodules are difficult to reverse. Previously reported therapeutic options are limited and include intralesional triamcinolone, massage, needling, and excision, each with inconsistent results or potential for scarring. OBSERVATION: We have observed complete resolution of calcium hydroxylapatite nodules after a single treatment with fractional carbon dioxide laser. CONCLUSIONS: A single session of fractional carbon dioxide laser treatment may resolve selected cases of calcium hydroxylapatite nodules. The mechanism of action may involve conversion of the product into tricalcium phosphates which dissolve readily. This novel therapeutic technique may enhance treatment options for a difficult clinical problem.

Silicone implant for chin augmentation mimicking a low-grade liposarcoma.

The silicone implant has been widely used in facial aesthetic surgery for chin augmentation. A case of a 71-year-old woman with a lesion in the anterior mandibular region detected by radiographies and suggestive of benign soft tissue tumor is presented. The patient denied previous surgical intervention in the mental area. A biopsy was performed and initially interpreted as low-grade liposarcoma. After an immunohistochemistry study showing CD-68-positive cells and complementary information regarding a silicone implant for chin augmentation, the definitive diagnosis was silicone granuloma. This case reinforces that silicone implant in the mandibular region can be misdiagnosed as malignant tumor and the correct diagnosis is heavily dependent on close collaboration between clinician and pathologist in order to avoid unnecessary surgical intervention.

Pseudotumor of the omentum with a fishbone nucleus.

A 23-year-old Japanese man was admitted with a chief complaint of abdominal pain. He was previously healthy, and his past medical history was unremarkable. Local tenderness and rebound tenderness at McBurney's point were elicited. Abdominal roentgenography was non-diagnostic. Ultrasonography and computed tomography showed a tumor with a central core. Based on a diagnosis of appendicitis with omental inflammation or an omental tumor, laparotomy performed. Intraoperatively, no site of gastrointestinal perforation was detected; however, a 5-cm omental granuloma was identified that proved to have a fishbone nucleus on pathological examination. The postoperative course was uneventful, and upper gastrointestinal endoscopy and barium enema were unremarkable. A large solitary omental pseudotumor is rare, and the clinical course in this case was atypical compared with the usual course of intestinal perforation by a foreign body and formation of an intra-abdominal granuloma.

Granuloma de colesterol de mama, una lesión que simula carcinoma mamario / Cholesterol granuloma of the breast. A lesion which mimics carcinoma

El granuloma de colesterol de la mama es una entidad clínico-patológica infrecuente y descrita pocas veces en la literatura médica. Se trata de una respuesta del organismo a la hemorragia localizada o a material lipídico extracelular. Se caracteriza por la presencia de células gigantes multinucleadas fagocitando cristales de colesterol. Su importancia radica en la posible confusión clínica y radiológica con un carcinoma de mama.Se describe el caso de una paciente de 54 años con una masa asintomática en la mama izquierda. (AU)

Acupuncture granulomas.

Silicone compounds have recently been a source of controversy with regard to their potential role in the genesis of collagen vascular diseases. Foreign body reactions to injectable silicone were noted early in its cosmetic use and led to subsequent abandonment of this procedure. Here we report the first documented case of silicone granulomas to occur after acupuncture.

Late-onset miliary pneumonitis after near drowning.

We report a 7-year-old pediatric patient with an apparently self-limiting, subacute miliary pneumonitis that occurred 6 weeks after a near-drowning accident in shallow, muddy water. After biopsy, histological examination revealed aspirated foreign bodies (algae and pollen grains) in the affected lung areas and a foreign body reaction in the form of a granulomatous inflammation. The lack of any detectable infectious agents suggested a causative role of these aspirated algae and pollen grains in the development of lung disease.
