Background: Myeloid sarcoma (MS) is a solid malignant tumour associated with infiltration of immature myeloid precursor cells in an extramedullary site. The term MS has replaced the term granulocytic sarcoma and chloroma, which were used in the past. MS in the oral cavity is very uncommon, with less of 40 cases reported until recently. Case Report: We report the first case, the features, and th...

Though proximal extremities, limb girdles and head, neck are common sites of occurrence, rarely cases of this unique entity have been reported in oral cavity. Chondroid lipoma due to its complex histology comprised of lipoblast like cells in myxoid and chondroid background, is apt...

Rhabdomyosarcoma (RMS), a tumor of skeletal muscle origin, is the most common soft tissue sarcoma encountered in childhood and adolescence. The common sites of occurrence are the head and neck region, genitourinary tract, retroperitonium, and, to a lesser extent, the extremities. In the head and neck region, the most commonly affected sites are the orbit, paranasal sinuses, soft tissues of the ...

Intraoral granulocytic sarcoma is an unusual manifestation of chronic or acute leukemia. The oral manifestations often involve enlargements of the gingival and mucosal tissue from direct leukemic cell infiltration. Only 38 cases have been reported in scientific literature to date. We present the case of a 47 year-old female who was diagnosed with chronic myeloid leukemia (CML) in December 2006....

Case series Oral manifestations of HIV disease are broadly classified as “strongly associated with HIV”, “less commonly associated with HIV” and “can be seen in HIV infection”. Malignancies reported in HIV infection include Kaposi’s sarcoma, Non-Hodgkin’s lymphoma and squamous cell carcinoma of the oral cavity.
