Tongue cancer in non-smoking and non-alcoholic mother and daughter.

Tongue cancer is more prevalent in male smokers and alcoholics. Although an increased incidence of tongue cancer has been noted in non-smoking and non-alcoholic women, reports of its occurrence in mother and daughter are extremely rare. Here, we report a case of a non-smoking and non-alcoholic mother and her daughter diagnosed and treated surgically for tongue squamous cell carcinoma (SCC).

Bilateral intra-lymph node Warthin's tumor as a potential diagnostic pitfall mimicking metastatic carcinoma.

Warthin's tumor (WT) is a benign and frequent salivary gland tumor primarily affecting the parotid gland. In some cases, this tumor can involve the extra parotid region and affect cervical lymph nodes. Fine-needle aspiration can be the first step in the diagnostic approach to lymphadenopathy; however, specimens from intra-nodal WT can present a potential pitfall, leading to a misdiagnosis of metastasis.

Influence of different methods for classification of lymph node metastases on the survival of patients with oral squamous cell carcinoma.

Background: Despite the advances in the classification of oral squamous cell carcinoma (OSCC) based on its extension by the TNM system, there is still a need for methods to better classify the patients to predict prognosis and indicate adjuvant therapy.

Objectives: To analyze the influence of the number of positive lymph nodes (PN), lymph node ratio (LNR), and log odds of positive lymph nodes (LODDS) in survival of patients with OSCC.

Methods: Clinicopathologic data from patients with OSCC who were treated with curative purposes by surgery and neck dissection (ND) with or without subsequent adjuvant therapies from 1991 to 2015 was retrospectively assessed.

Potential of lymph-node ratio as a prognostic factor for patients with oral squamous cell carcinoma.

Background: To analyze the influence of the lymph node ratio (LNR) in survival of patients with OSCC METHODS: Clinicopathologic data from patients with OSCC who were treated with curative surgery and neck dissection (ND) with or without adjuvant therapies from 1991 to 2015 was retrospectively assessed. The impact of LNR and other variables on overall survival (OS) and disease-free survival (DFS) was analyzed in univariate and multivariate analyses.

Results: One hundred nineteen patients were included.

Clinicopathological and prognostic profile of non-smoking and non-drinking head and neck cancer patients: a population-based comparative study.

Tobacco and alcohol consumption are the main risk factors for head and neck cancer (HNC). However, some individuals do not have a history of addiction and even so they develop the disease. This study evaluated clinicopathological and prognostic features of non-smoking and non-drinking (NSND) HNC patients.

Blastoid variant of mantle cell lymphoma in palatine tonsil.

Blastoid variant of mantle cell lymphoma (MCL) is an aggressive and extremely rare malignancy. MCL may be diagnosed in lymph nodes and/or extranodal sites exhibiting a poor prognosis. MCL with primary presentation in palatine tonsils has been rarely reported.

In situ melanoma of oral cavity: Diagnosis and treatment of a rare entity.

Oral melanoma is an extremely aggressive and rare tumor. Commonly, oral melanomas are diagnosed as invasive tumors, which considerably reduces the chances of cure. In situ oral melanomas being exceedingly rare, which makes its clinicopathological and prognostic characteristics poorly known.

Multifocal papillary carcinoma of the thyroid with heterotopic ossification and extramedullary hematopoiesis associated with a lipomatous follicular nodule.

Heterotopic ossification has been described in papillary thyroid carcinoma in association with high incidence of extrathyroidal invasion, multifocality, lymph node metastasis, and older age. Nevertheless, it has not been described as a specific subtype of papillary thyroid carcinoma, because of its rarity. We described the case of an 80-year-old female patient, with familial history of papillary thyroid carcinoma.

Lip Cancer: A Clinicopathological Study and Treatment Outcomes in a 25-Year Experience.

Purpose: There are few clinical studies focusing on treatment outcomes of lip cancer. This study investigated the clinicopathologic variables of a large sample of patients with lip squamous cell carcinoma (LSCC) treated in a reference head and neck cancer center for the past 25 years and analyzed the influence of these variables on treatment outcomes.

Materials And Methods: This retrospective cohort study reviewed the clinical records of patients with LSCC.

Gingival metastasis from salivary duct carcinoma of the parotid gland.

Background: This article reports a rare case of metastasis of salivary duct carcinoma of the parotid gland to the gingiva and reviews the occurrence of metastatic processes to the oral mucosa.

Methods: A 67-year-old white male presented with a chief complaint of a painless nodular tissue growth on the gingiva with reportedly 5 months of evolution. The intraoral examination revealed a reddish, superficially ulcerated nodular lesion ( approximately 2 cm in diameter) on the right mandibular buccal attached gingiva, and the clinical aspect was that of a benign reactive lesion.
