Microscopic appearances of commonly implanted food particles.

Background: Pathologists come across various structures in the microscopic sections that are unrelated to the tissues. Artifacts can occur in the tissue from the time the area is prepared for biopsy, during fixation, grossing, processing, sectioning and staining of the specimen. Food substances may get entrapped into the oral tissues and can lead to misdiagnosis.

Volatile Organic Compounds in Human Breath.

A comprehensive analysis of volatile organic compounds (VOCs) from the exhaled breath sample is termed as breathomics. Breath samples are a complex mixture composed of a multitude of VOCs and other molecules. The analysis of total VOCs in exhaled breath provides a promising tool for the diagnosis of many diseases because it enables the observation of biochemical processes in the body in a non-invasive way.

Clear-cell variant of oral squamous cell carcinoma: A rare entity.

Clear-cell variant of oral squamous cell carcinoma is an extremely rare entity in the maxillofacial region. We report a case of 42-year-old female who presented with a soft-tissue growth with erythematous and nonscrapable irregular white patches on the left alveolar mucosa for the past 3 months. Histopathologic examination showed lobules and sheets of clear cells with features of malignancy extending from the surface epithelium.

Odontogenic sarcoma: First report after new who nomenclature with systematic review.

Ameloblastic fibrosarcoma (AFS) now designated as odontogenic sarcoma is a malignant odontogenic tumor characteristically composed of a benign epithelium and a malignant mesenchymal component. It can arise without any preexisting lesion or it can result from the malignant transformation of ameloblastic fibroma (AF). Hereby, we report an extremely rare case of odontogenic sarcoma which was transformed from AF over a period of about 2 years.
