Plasmacytoma masquerading as an abscess.

Plasma cell neoplasia is a lymphoid neoplastic proliferation of B cells and has been classified as multiple myeloma, solitary plasmacytoma, and extramedullary plasmacytoma. Extramedullary plasmacytoma is defined as neoplastic proliferation of plasma cells in the soft tissue. Extramedullary plasmacytoma of the head and neck is very uncommon tumors, representing approximately 0.4% of all head and neck malignancies; amongst them, plasmacytoma of the maxilla is extremely rare. We present a case of a 70-year-old male with swelling on the right middle third of the face, mimicking an abscess, but proven to be extramedullary plasmacytoma. This report discusses the clinical, radiographic, histological, and immunohistochemical features of extramedullary plasmacytoma.

Hand-Schüller-Christian disease

Langerhan cell histiocytosis, formerly known as histiocytosis X, traditionally denotes a group of diseases that stem from proliferative reticuloendothelial disturbances.The etiology and pathogenesis of the disease remain debatable. In this paper we report a case of Langerhan cell histiocytosis in a 3 1/2 -year-old child who reported to the department of oral pathology with gingival enlargements. The radiological features and histopathological features are also discussed.

Odontogenic Myxoma of the Maxilla Infiltrating the Maxillary Sinus: A Rare Case Report

Odontogenic myxomas are tumors derived from embryonic mesenchymal elements of dental anlage. Although benign, odontogenic myxomas draw great attention because of their invasive nature into the surrounding tissues, which make the tumour amenable to recur especially after conservative treatment. We present a case of odontogenic myxoma with a displaced maxillary molar in the sinus, an unusual radiographic finding reported in literature.
