Objective: The purpose of the study was to present the clinical and microscopic features of oral foreign body granulomas associated with the injectable dermal filler Radiesse, and to increase awareness of this potential complication as the use of dermal fillers by the aging Baby Boom generation increases.
Study Design: Demographic and clinical data of 8 patients with foreign body granulomas containing the characteristic microscopic appearance of hydroxyapatite microspheres were studied. Analysis of the microspheres of 1 case was carried out by energy dispersive x-ray microanalysis to confirm the calcium and phosphorus content.
Results: The clinical and microscopic appearance of Radiesse-induced foreign body granulomas is illustrated and discussed.
Conclusions: Foreign body granulomas containing hydroxyapatite microspheres in patients receiving treatment with the cosmetic filler Radiesse have a characteristic microscopic appearance. Oral Radiesse-induced nodules occur more often in older women, most commonly in the lips and the mandibular labial vestibule.

Inadvertent Ingestion of Orthodontic Wire Impacted in the Esophagus, Mistaken for a Chicken Bone.

Accidental ingestion of foreign bodies frequently necessitates emergency department visits, with many cases requiring surgical consultation. Although most ingested items pass through the gastrointestinal tract uneventfully, orthodontic components, such as wires, present a specific risk due to their shape and material properties. This report describes a rare case of a 13-year-old male adolescent whose initial presentation suggested ingestion of a chicken bone.

Intracardiac migration of inferior vena cava (IVC) filter or stent is a rare but potentially fatal complication of endovascular venous device placement. There is no consensus whether migrated stents should be surgically removed by open cardiac surgery or retrieved by the percutaneous endovascular route and whether an intervention should be performed immediately or expectantly. Herein, we report a 39-year-old female who received emergent left lobe living donor liver transplantation (LDLT) owing to posthepatectomy liver failure.

Background: Gauzoma is a foreign body reactive granuloma which is an extremely rare complication of thoracic surgery. We describe a case of a Gauzoma in which the gauzes were removed by mini-thoracotomy as a less invasive procedure, discovered incidentally after 35 years of follow-up.
Case Presentation: A 51-year-old man was referred to our department for hyperhidrosis treatment, and imaging studies and biopsy confirmed the diagnosis of Gauzoma.
