Basaloid squamous cell carcinoma of gingiva: A rare case report.

Basaloid squamous cell carcinoma (BSCC) is an exceptional, aggressive variant of squamous cell carcinoma (SCC) because of its unique histological feature and an ominous clinical behavior. Recently, it has been recognized as a high-grade SCC. The most preferential site of occurrence is the upper aerodigestive tract.

Mucormycosis occurring in an immunocompetent patient: a case report and review of literature.

Mucormycosis is an opportunistic fungal infection with a high fatality rate and is the third most common fungal infection that is invasive in nature, next to candidiasis and aspergillosis. The condition is generally vasotropic and angio-invasive in nature. It gets disseminated to a wider area locally and also exhibits a distant spread.

Caspase cascade pathways of apoptosis in oral pemphigus: An immunohistochemical study.

Background: Pemphigus is a group of autoimmune blistering diseases characterized by loss of keratinocyte cell adhesion that leads to blister formation clinically. Induction of apoptosis or of proapoptotic proteins by pemphigus immunoglobulin G (IgG) may be part of the mechanism by which IgG induces acantholysis. Some of the current data suggest that activation of proapoptotic proteins such as bax and caspase cysteine proteinases may sensitize cells to the acantholytic effects of pemphigus IgG.
