Condyloma acuminatum (CA) is human papilloma virus-induced disease, rarely involving oral cavity, usually sexually transmitted and frequently occurs in anogenital areas. Oral lesions are being present predominantly on the tongue, lip mucosa, buccal mucosa, palate and floor of the mouth. The disease is more common in teenagers and appears as solitary or multiple, sessile or pedunculated masses. Here, we report the unique case of CA on the lower lip in a 45-year-old man, showing changes in the excretory duct of the minor salivary gland, which is relatively unusual. The majority of the head and neck squamous cell carcinomas (HNSCC) occur in the oral cavity. Even with advances in cancer therapy only minor improvements in the survival of HNSCC patients have taken place and approximately 350,000 patients die annually of HNSCC worldwide. Tumor budding (TB) is a novel and promising histo-morphological parameter that has been studied in many cancers. The presence of TB is associated with lymph node and distant metastasis as well as poor survival, independently of the applied scoring system. The depth of tumor invasion (D) measured from the surface of the tumor to the deepest point of invasion is also an important prognostic parameter for oral squamous cell carcinoma (OSCC) with a cutoff point of 4 mm. Both taken together constitute BD model and it has also been found to be an independent prognostic factor for patients with OSCC. Therefore, it would be highly beneficial to evaluate TB and BD model in routine histopathological reporting. This study aims to compare the detectat the tumor invasive front. Tissues submitted for histopathological diagnoses are routinely fixed in formaldehyde fixative which facilitates tissue storage for the extended period of time for further investigation or research purpose. The literature has reliable data relating to immunohistochemistry and molecular studies done using tissue fixed in formalin for longer duration and in paraffin-embedded tissue blocks. We have attempted to evaluate staining adequacy of archival specimens using hematoxylin and eosin (H&E) and trichrome stains. We compared staining adequacy in tissues stored in formalin for a minimum period of 5 years labeled as long term fixed tissues (LFT) and corresponding 5-year-old paraffin-embedded tissue blocks of same cases available in the archives designated as old tissue blocks (OTB), along with freshly fixed tissues (FFT) used as controls. Fifty-one tissue sections in each study group were stained with H&E, Mallory's trichrome and Van Giesons' and microscopic evaluation was carried out using Research Mank and source for prospective studies. Odontogenic cysts (OCs) constitute a major part of oral pathological lesions, but little is known about their distribution patterns in various populations. The aim was to determine the prevalence and factors associated with the cases of histopathologically diagnosed OCs that report to our institution and to analyze the factors associated with the presence of OCs and to study the biologic behavior of different types of cysts. A cross-sectional study was performed on 596 oral and maxillofacial specimens during 2013-2017. Out of these, the cases which were histopathologically proven as OCs were separated and data were collected and analyzed regarding the age, gender, primary symptom, site, radiographic feature, histopathologic diagnosis, treatment given, recurrences and associated conditions if any. Of the 596 cases included in the study, 67 (11.2%) had a histopathological diagnosis of OCs. 41 cases were inflammatory cysts and 26 developmental cysts. 28 cases (41.8%) were reported as periapical cysts, 10 cases (14.9%) were odontogenic keratocysts (OKCs), 9 cases (13.4%) were dentigerous cysts, 8 cases (11.9%) were inflamed cyst wall, 5 cases (7.5%) each of residual cyst and developmental OCs and one case (1.5%) each of ortho
