A 34-year-old man presented with an expansile, erosive tumor involving the left side of the mandible, with secondary invasion into the maxilla, measuring 13 Χ 7 cm. Microscopic analysis revealed a malignant small round cell neoplasm with focal cartilaginous differentiation. Immunohistochemical analysis revealed positivity for vimentin, NSE and CD99 with primitive small round cells, and S100 positivity with neoplastic chondrocytes. To the best of our knowledge, this is perhaps the largest reported case of mesenchymal chondrosarcoma of the maxillofacial region. Diagnosed as inoperable, he was treated with radiation and chemotherapy only to die within a few months.

Juvenile ossifying fibroma is an uncommon benign but aggressive fibroosseous lesion that affects the craniofacial skeleton. Their distinct clinical and histopathological features warrant the lesion to be considered as a separate entity from other fibro-osseous group of lesions such as fibrous dysplasia and cemento ossifying fibroma. Concomitant development of secondary aneurysmal bone cyst may rarely occur, which makes the lesion more aggressive and difficult to treat. We report a case of a 6 year old girl who was diagnosed with aneurysmal bone cyst during her earlier presentation at a private hospital and was treated for the same. The lesion recurred within 6 months. The second incisional biopsy specimen revealed features of trabecular variant of juvenile ossifying fibroma along with areas of aneurysmal bone cyst.

Cancrum oris is an orofacial gangrene, which during its fulminating course causes, progressive and mutilating destruction of the infected tissues with a consortium of microorganisms. This condition is considered to represent the “face of poverty” because factors connected with poverty, such as chronic malnutrition, poor oral hygiene and sanitation, faecal contamination, and exposure to viral and bacterial infections in an immunosupressed host contribute to disease progression. This condition is seen almost exclusively among the young children and carries a high mortality rate. We present a case of cancrum oris in a 45 years old lady being treated for acute myeloid leukemia with chemotherapy, who in addition to a polymicrobial bacterial infection had superinfection with Mucormycosis.

Breast conservation therapy is currently considered as a viable alternative to mastectomy in early breast cancer. Radiotherapy by virtue of its ability to reduce local recurrences is an integral component of breast conservation therapy. Apart from irradiating the whole breast, the tumor bed is usually delivered a boost dose in breast conservation therapy to increase the local control rate. One of the methods which has been adopted to selectively boost the tumor bed to high doses is the use of per-operative high dose rate interstitial implants. This particular paper deals with our department's experience with breast conservation therapy using per-operative template guided, High Dose Rate (HDR) interstitial implants in early breast cancer. Local control rates, disease free survival and cosmetic benefit with this technique will be discussed along with literature review.
