An insight into diagnosis of a hidden entity: Impacted food material

Foreign bodies and tissue reactions to foreign materials are commonly encountered in the oral cavity. Exogenous materials causing foreign body reactions may be metallic (amalgam) or nonmetallic (suture materials, vegetable matter). Implantation of food particles in the oral tissues has been known to cause reactive lesions such as oral pulse granuloma. Implantation could be through extraction sockets, deep periodontal pockets, associated with tumor growth, interdental areas of teeth, unfilled root canals, and grossly decayed teeth. These get rapidly digested and altered by host responses. Cellulose persists as hyaline material and invokes chronic granulomatous response. This change may mimic other pathologies. Materials and Methods: Representative specimens from commonly consumed food groups were selected, fixed in 10% neutral buffered formalin, processed, sectioned, stained with hematoxylin and eosin stain and observed under light microscope. Results: Each specimen revealed unique, distinct histology of each food type. The plant materials had a characteristic appearance of rigid double cell wall while rigid regular partitions containing nutrient material were revealed in seeds and beans. Starch-contained lentils exhibited clear spaces. Following is a brief description of some of the significant histological findings of each of the specimens processed and stained. Conclusion: Thus, the study of histological structure of vegetables and legumes will enable their easy recognition in oral biopsy samples and help in distinguishing them from other pathologies and artifact.

Distrofia corneal granular / Granular corneal dystrophy

Las distrofias corneales constituyen un conjunto de enfermedades que presentan, en su mayoría, una baja incidencia y se caracterizan por acúmulo de material hialino o amiloide que disminuyen la transparencia corneal. La distrofia granular es una enfermedad autosómica dominante que presenta opacidades grises en el estroma superficial central de la córnea y se hacen visibles en la primera y segunda décadas de la vida, lo que provoca disminución de la visión más significativa cerca de los 40 años de edad. Presentamos dos casos clínicos de distrofia granular en pacientes hermanos de diferentes sexos, quienes acudieron a la consulta y refirieron visión nublada. El estudio de la historia familiar nos ayuda en el correcto diagnóstico y la biomicroscopia constituye el elemento más importante(AU)

Corneal dystrophies are a group of diseases that mostly have low incidence rates and are characterized by accumulation of hyaline or amyloid material that reduces the corneal transparency. Granular dystrophy is a dominant autosomal disease with gray opacities in the central superficial stroma of cornea, which are visible in the first and second decades of life and leads to significantly reduced vision when going into the 40 years of age. Here are two clinical cases of granular dystrophy in a pair of siblings who went to the doctor's because of blurred vision. The study of the family history helps the physician to reach a right diagnosis and the most important element is biomicroscopy(AU)
