Initially thought to affect mainly the respiratory system, it strikes all vital organ systems and cause defects in cardio-circulatory, respiratory system and gastrointestinal systems to name a few leading to copious biochemical alterations.

Metastasizing Ameloblastoma: A 10 Year Clinicopathological Review with an Insight Into Pathogenesis.

Ameloblastoma, a benign but locally aggressive odontogenic tumor, often demonstrates metastasis despite benign histological features and this variant is termed as metastasizing ameloblastoma (METAM). It was classified under the malignant category in the 2005 WHO but has been re-classified under benign epithelial odontogenic tumors in the latest 2017 WHO classification. The present review aimed at gathering the available data on METAM to update the current cognizance about the pathology.

Both clinical and histopathological diagnoses of reactive lesions were selected for the study.

Numb chin syndrome associated with metastatic invasive ductal carcinoma of breast.

Numb chin syndrome (NCS), also known as mental nerve neuropathy, is characterized by facial and oral numbness restricted to the distribution of the mental nerve. Although not a common neuropathy, the clinical importance of this syndrome is its frequent association with malignancies. A 56-year-old Indian female reported with a complaint of numbness on the left side of chin.

Immunohistochemical expression of CD34 and basic fibroblast growth factor (bFGF) in oral submucous fibrosis.

Background: Oral submucous fibrosis (OSMF) is an insidious chronic fibrotic condition that involves the oral mucosa and occasionally the pharynx and esophagus. Vascularity in OSMF has always been a matter of debate. The prevailing concept is that epithelial atrophy occurs due to lack of perfusion but the recent data challenges this concept.

Plasma cell myeloma infiltrating the dental pulp: An interesting finding.

Plasma cell myeloma (PCM) is a clonal neoplastic proliferation of terminally differentiated B lymphocytes (plasma cells/myeloma cells) that involves the skeletal system in a multifocal fashion. Even though jaw involvement has been reported in as many as 30% of cases, myeloma cells infiltrating into the pulpal tissue is extremely rare. Here, we present a case of PCM in which myeloma cells are seen infiltrating into the pulpal tissue of 46.

Disseminated histoplasmosis with oral and cutaneous manifestations.

Histoplasmosis is a systemic mycotic infection caused by the dimorphic fungus, Histoplasma capsulatum. Systemic histoplasmosis has emerged as an important opportunistic infection in human immunodeficiency virus (HIV) patients and those in endemic areas. Reported cases of histoplasmosis have been low in India with less than 50 cases being reported.

Intraosseous lipoma of mandible presenting as a swelling.

Lipomas are the most common form of benign mesenchymal tumors and are composed of mature adipocytes. They can occur anywhere in the body where fat is found and thus, called as the 'universal tumor' or the 'ubiquitous tumor'. Intraosseous lipomas (IOL) are among the rarest (0.

Amelanotic melanoma masquerading as a granular cell lesion.

Amelanotic melanoma (AM) presents a diagnostic challenge due to its wide clinical presentations, lack of pigmentation, and varied histological appearances. Immunohistochemistry plays a crucial role in the diagnosis of these lesions. Amelanotic melanoma of oral mucosa is an uncommon lesion.

Clear cell variant of intraosseous mucoepidermoid carcinoma: Report of a rare entity.

Intraosseous mucoepidermoid carcinoma of jaw bones is a rare lesion. Abundance of clear cells in an intraosseous mucoepidermoid carcinoma may complicate its histopathologic diagnosis. It becomes extremely important to distinguish this lesion from other clear cell lesions of jaw region.

Necrotizing sialometaplasia of tongue.

Necrotizing sialometaplasia, is a benign inflammatory lesion primarily involving the minor salivary glands of the hard palate. The lesion often presents itself as a deep-seated palatal ulcer with clinical and histological features similar to those of a malignant neoplasm.
