Fine-needle aspiration biopsy (FNAB) is a cost-effective and safe office procedure performed to evaluate thyroid nodules. We report a case of a 33-year-old woman who presented with pain and swelling of the thyroid after undergoing an FNAB for a right thyroid nodule at an outside hospital. The patient received a course of antibiotics without complete resolution of her symptoms and ultimately, underwent a right thyroid lobectomy. Pathology of the excised thyroid tissue showed chronic lymphohistiocytic inflammation with giant cell reaction and hemorrhage consistent with a foreign-body reaction. The patient's symptoms completely resolved after the surgery. Though uncertain what foreign body was introduced into the thyroid tissue during the FNAB, we surmise that an accidental introduction of ultrasound gel may have caused this rare and unexpected complication of a procedure with usually few and manageable complications.

Neural electrodes used for bidirectional communication between the nervous system and external devices like prosthetic limbs have advanced in neuroprosthetic applications. However, their effectiveness is hindered by the foreign body reaction, a natural immune response causing inflammation and fibrosis around the implanted device. This process involves protein adsorption, immune cell recruitment, cytokine release, and fibroblast activation, leading to a fibrous capsule formation and a decrease in electrode functionality.

Biomaterial scaffold engineering presents great potential in promoting axonal regrowth after spinal cord injury (SCI), yet persistent challenges remain, including the surrounding host foreign body reaction and improper host-implant integration. Recent advances in mechanobiology spark interest in optimizing the mechanical properties of biomaterial scaffolds to alleviate the foreign body reaction and facilitate seamless integration. The impact of scaffold stiffness on injured spinal cords has not been thoroughly investigated.

Foreign body granuloma (FBG) is an inflammatory reaction to an exogenous agent. This entity is well known on the cutaneous organ but very rarely described in the abdominal cavity. We report three clinical cases of intraperitoneal FBG following major debulking of pseudomyxoma and intraperitoneal hyperthermia chemotherapy.

We report a case of a woman in her late 40s with a history of breast implant surgery following breast cancer treatment. She presented with asymmetrical breast enlargement, palpable contralateral axillary lymph nodes and cutaneous nodules on both forearms. In addition, imaging evaluation revealed intracapsular implant rupture, ipsilateral internal mammary enlarged lymph nodes and multiple mediastinal lymphadenopathies.

Objectives: This study aims to identify patterns and to describe the clinical course of delayed adverse tissue responses in patients who underwent orthognathic osteotomy with biodegradable osteofixation.
Patients And Methods: Through a retrospective review of cases between 2013 and 2020, we identified three patients who underwent bimaxillary osteotomy and fixation with unsintered-hydroxyapatite/poly-L lactic acid (u-HA/PLLA) devices, after which they developed delayed inflammation. These lesions were treated with drainage and/or removal of the devices.
