Diffuse Large B Cell Lymphomas (DLBCL) encompasses a heterogeneous group of tumors that together constitute the commonest of all Non Hodgkin Lymphoma (NHL) and the proclivity of DLBCL to oral cavity is unknown. They mostly arise from soft tissues as asymptomatic lesions, mostly without 'B' symptoms and involvement of jaw bones is uncommon. Most studies and case reports of oral DLBCL's are based on, manifestation of primary extra-nodal disease or a component of a disseminated disease process involving regional lymph nodes. Many investigators have proposed that patients with this cell type who maintain a complete response for 24 consecutive months are cured because late relapses seldom occur. With advances in treatment modalities, many patients with NHL become long-term survivors and the risk of relapses or second tumors are of growing concern. We present a case of DLBCL which relapsed after five years of initial lesion in a 41 year old female patient and presented as a nonspecific bilateral anterior maxillary radiolucency. DLBCL usually express pan-B markers with small percentage expressing T-cell markers. Few rare cases of DLBCL have shown CD3 expression, which is a most sensitive T-cell marker which was focally expressed in the present case.

The peripheral odontogenic fibroma is a relatively rare, benign, unencapsulated and gingival mass of fibrous connective tissue, considered to be the extraosseous counterpart of the central odontogenic fibroma. Peripheral odontogenic fibroma was earlier quite commonly confused with peripheral ossifying fibroma, until WHO classification (1992), classified it under odontogenic tumours. Peripheral odontogenic fibroma is seen so infrequently that little is known about this neoplasm; the largest series of cases have been that of Farman who found five cases in the literature and added another 10 cases. Through this case report we try to clarify the features of this condition and attempt to clear its distinction with other commonly occurring conditions.

Aneurysmal bone cysts (ABCs) are rare benign lesions seen as locally destructive, rapidly expansile, and mostly affecting the long bones and vertebrae. The association of ABCs with juvenile psammomatoid ossifying fibroma (PsJOF) is predominantly seen in the extra gnathic region, and it is extremely rare with only a few cases reported so far in the mandible. Here, we report one such case of a hybrid lesion in a 30-year-old male, who presented with a solitary swelling of the right mandible showing partial obliteration of lingual vestibular sulcus, which was histologically confirmed as PsJOF as a preexisting lesion, transforming into an ABC. Such hybrid lesions are usually misdiagnosed and have been sparsely reported in the literature.
