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 diagnos...

Orbital injuries with a foreign body may result in severe structural and functional damage to the eye or orbital contents. The clinical presentation of an orbital foreign body is variable. Management and prognosis depend on the composition, location of the object and presence or absence of secondary infection. Metallic objects and glass particle foreign bodies are the most frequently encountere...

The polymerase chain reaction (PCR) is an elegant technology for faithfully replicating and amplifying the master molecule of life, but a valid scientific procedure remains essential without which the resulting data have only very limited value. The presence of microbial infection in the complex apical root canal system is the major cause of posttreatment apical periodontitis in well-treated te...

The polypropylene mesh, although is one of the most used prosthetic biomaterials for abdominal wall defects, proved not to be completely inert, generating from precocious foreign body inflammatory reactions (varying by individual reactivity, the amount of used material and its structure), to late complications such as chronic infections, stercoral fistulae or mesh migration. The present paper w...

introduction: tracheobronchial foreign body may often be treated as asthma, chronic bronchitis or etc. especially in patients with no memories of aspiration episodes. case presentation: a 74-year-old woman, suffering from persistent cough, was temporarily misdiagnosed with allergic bronchopulmonary aspergillosis and treated for six months. during this period, computed tomography (ct) findings c...

introduction: the phenomenon of neglected foreign bodies is a significant cause of morbidity in soft tissue injuries and may present to dermatologists as delayed wound healing, localized cellulitis and inflammation, abscess formation, or foreign body sensation. localization and removal of neglected soft tissue foreign bodies (stfbs) is complex due to possible inflammation, indurations, granulat...

Giant cells are the soldiers of defensive system of our body. They differ based on the stimuli that provoked their formation. On the other hand, squamous cell carcinoma (SCC) being the most common oral cancer, presents with varied histopathological features based on the degree of differentiation. Keratinizing islands of dysplastic squamous epithelial cells & a dense inflammatory response form t...

Orbital injuries with a foreign body may result in severe structural and functional damage to the eye or orbital contents. Management and prognosis depend on the composition and location of the foreign body and whether there is secondary infection. Metallic objects and glass are the most frequently encountered and well-tolerated, whereas organic foreign bodies can elicit an inflammatory reactio...
