ABSTRACT

Context: Maspin is a novel serine protease inhibitor (serpin) with multifaceted tumor‑suppressive activities. It was originally identified in normal human breast myoepithelial cells and shows variable expression in different types of cancer cells. Maspin displays anti‑metastatic properties in mammary and prostate cancer. Its expression is maintained during ovarian, lung and pancreatic carcinogenesis, indicating that Maspin regulated metastatic potential is tissue specific. Thus, it is possible that Maspin participates in salivary gland tumor biology as well. In this study, expression pattern of maspin in benign and malignant salivary gland tumors is analyzed, to understand the biological behavior of salivary gland tumors with respect to maspin expression. Aims and Objectives: The aim of this study was to demonstrate, record, and correlate the expression pattern of maspin in benign and malignant salivary gland tumors. Settings and Design: A retrospective study of maspin expression in 30 diagnosed cases of benign and malignant salivary gland tumors retrieved from archives of our department. Materials and Methods: Anti‑maspin antibody and horseradish peroxidase detection system. Statistical Analysis: Descriptive statistical analysis and Chi‑square/Fisher Exact test. Results: Intense expression with P < 0.001 is associated with benign tumors, nuclear staining with P < 0.001 is significantly associated with benign tumors and cytoplasmic staining with P = 0.020 is associated with malignant tumors. Conclusion: Intensity of expression is more in benign tumors when compared with malignant tumors. The benign tumors showed both nuclear and cytoplasmic expression. Some malignant tumors did express maspin, but mainly in the cytoplasm.

ABSTRACT

Progressive anterior segment fibrosis syndrome (ASFS), after intraocular surgery in older children (≥9 years) and adults with congenital aniridia, is described in the literature. In this report, we describe an unique case of ASFS in an infant with congenital aniridia following a combined trabeculotomy‑ectomy and its recurrence after a descemet stripping endothelial keratoplasty. The ophthalmologists should be well aware of this entity and warn the parents about its possibilities. Use of immunomodulators or prolonged anti‑inflammatory therapy may be considered to prevent its occurrence.

ABSTRACT

Benign fibrous histiocytoma (BFH) is a benign fibrohistiocytic neoplasm. It is documented to occur in all anatomic sites with a strong predilection for sun exposed skin surfaces. Intra oral occurrence of BFH comprises a lesser percentage of cases with tongue being the least reported site. We report a case of BFH of the tongue with an emphasis on its histogenesis and a review of the literature.

ABSTRACT

Keratoconus is the most common corneal ectatic disorder, the cause of which is largely unknown. Many factors have been implicated, and the ocular allergy is being one of them. The commonly proposed pathogenesis includes the release of inflammatory mediators due to eye rubbing which may alter the corneal collagen and lead to corneal ectasias. The onset of keratoconus is often early in cases associated with allergy and routine corneal topography may detect subtle forms of keratoconus. These cases may require early keratoplasty and are at an increased risk of having acute corneal hydrops. Surgical outcomes are similar to primary keratoconus cases. However, post-operative epithelial breakdown may be a problem in these cases. Control of allergy and eye rubbing is the best measure to prevent corneal ectasias in cases of ocular allergy.
