Relevance of Tumor Budding and Pattern of Invasion in Oral Squamous Cell Carcinoma.

Background: Standard histopathological parameters such as depth of invasion (DOI), lymphovascular invasion (LVI), and perineural invasion (PNI) are known parameters that can correlate with the prognosis and aggressiveness of oral squamous cell carcinomas (OSCCs). Tumor budding (TB) (≤5 tumor cells at infiltrating borders) and pattern of invasion (POI) are emerging histopathological parameters that have shown promising results as reliable risk factors in predicting nodal metastasis in early OSCCs.

Aim: The aim of the study was to assess TB and POI in OSCCs.

Pretreatment hematological parameters as predictors of tumor granulocyte-colony-stimulating factor expression in patients of head-and-neck squamous cell carcinoma.

Background: Tumor secreting granulocyte-colony-stimulating factor (G-CSF) and/or G-CSF therapy has been documented as a poor prognostic factor. Tumor G-CSF study is a relatively costly and sparsely available investigation. Therefore, this study was undertaken to predict tumor G-CSF score from pretreatment hematological parameters (PTHP) in patients of head-and-neck squamous cell carcinoma (HNSCC).

Metastatic malignant melanoma: A case of metastasis from foot to mandibular anterior region.

Metastatic malignant melanoma (MMM) of the oral cavity is extremely rare which generally presents in the setting of disseminated disease and have extremely poor prognosis. The most common site for MMM in the oral cavity is tongue followed by buccal mucosa for soft-tissue lesions and posterior mandible for bone involving lesions. Primary tumor sites of oral MMM are usually cutaneous lesions of the trunk, head and neck, limbs, and nasal septum mucosa.

Proliferative verrucous leukoplakia: An update.

Proliferative verrucous leukoplakia (PVL) is a rare form of oral leukoplakia, which was first described in 1985 by Hansen et al. Since then, various published case series have presented PVL as a disease with aggressive biological behavior due to its high probability of recurrence and a high rate of malignant transformation, usually higher than 70%. PVL is a long-term progressive condition, which is observed more frequently in elderly women, over 60 years at the time of diagnosis.

Nonsyndromic Synchronous Multifocal Central Giant Cell Granulomas of the Maxillofacial Region: Report of a Case.

Central giant cell granuloma (CGCG) is a benign proliferation of fibroblasts and multinucleated giant cells that almost exclusively occurs in the jaws. It commonly occurs in young adults showing a female predilection in the anterior mandible. Multifocal CGCGs in maxillofacial region are very rare and suggestive of systemic diseases such as hyperparathyroidism, an inherited syndrome such as Noonan-like multiple giant cell lesion syndrome or other disorders.
