ABSTRACT
BACKGROUND: Universally accepted fixative is 10% formalin which has been used for preserving the tissues and their architecture. In certain conditions, formalin might not be readily available for immediate fixation. We here by explore more economical, eco-friendly and easily available solutions that can be used as transit media/ transporting media for tissue specimens. MATERIALS AND METHODS: The study included commonly available solutions like Spirit, Saline, Betadine solution, Hydrogen peroxide (H2O2), Local anesthesia (L.A), Rose water, Coconut oil, Coconut water, Ice cold water, Honey and Milk while keeping formalin as control. The fresh tissue sample was cut into multiple bits and placed in different containers for a period of 8 hours before transferring to formalin solution. CONCLUSION: Transit fixatives are very important in certain situations where formalin is not readily available. These fixatives can be used to fix the tissues for a period of at least 8 hours without causing any damage or distortion before they are fixed in formalin solution.
ABSTRACT
Lymphomas are malignant neoplasms arising from lymphocytes B cell or T cell that affects mainly lymph nodes, spleen and other non hematopoietic tissues. They are classified as Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL). Diffuse large B-cell lymphoma (DLBL) is the most common variant of non-Hodgkin's lymphomas and frequently involves extranodal sites. In the oral soft tissues lesions can occur as hard and diffuse tumors involving oral vestibule, gums and posterior region of the hard palate. Most lymphomas, including DLBL arise from B cells are characterized by diffuse population of large cells with cleaved or non cleaved oval nuclei. Both histopathlogical and immunohistochemical (IHC) analysis were strongly advisable for proper management and prognosis. We hereby report a rare case of Diffuse large B-cell variant of non-Hodgkin's lymphoma in a male patient of age 50yrs in left upper buccal vestibule.
ABSTRACT
Odontoameloblastoma are tumours which represent a histological combination of ameloblastoma and complex odontoma. It behaves in an invasive manner like Ameloblastoma and is more aggressive in nature. We report a new case of ameloblastic fibro-odontoma (AFO). Clinical, radiographic and histopathological features are discussed.
