ABSTRACT Laryngeal cancer ranks third among the most common head and neck neoplasms. The most common histological subtype is squamous cell carcinoma, and neuroendocrine tumors are rare. An even rarer entity is a composite tumor with both these histologies. This case reports a metastatic combined carcinoma of squamous cells and large neuroendocrine cells, presenting favorable response to treatment with a total laryngectomy followed by adjuvant therapy including chemo-, radio-, and immunotherapy.

Highlights Twenty-eight cases of bladder squamous cell carcinoma cases were evaluated for p16, p53, p63 immunohistochemistry, and HPV PCR. Neither direct HPV detection nor its indirect marker (p16) was identified in most cases. Decision trees constructed described the relationships of a variety of clinicopathological features with high classification accuracy.   ABSTRACT Objective To investigate the expression of human papillomavirus (HPV), p16, p53, and p63 in non-schistosomiasis-related squamous cell carcinoma of the bladder and to develop an accurate and automated tool […]

ABSTRACT Cemiplimab is a novel programmed death-1 inhibitor recently approved for advanced cutaneous squamous cell carcinoma. Immune-related adverse events derived from cemiplimab are similar to other anti-PD-1 drugs, including gastrointestinal and cutaneous toxicities. Oral immune-related adverse events were not reported with cemiplimab in previous studies; thus this case report warns of the fact that the oral cavity may be a site of immune-related adverse events during programmed death-1 block therapy and that this can lead to significant limitations when not […]

ABSTRACT Percutaneous endoscopic gastrostomy is used to provide enteral nutritional support for patients with obstructive oropharyngeal or esophageal neoplasms. The placement of the catheter is considered safe, with few complications. Despite this, a specific complication that is considered rare, has been increasingly described in the literature, i.e., metastasis of head and neck cancer in the gastrostomy stoma. In this report, we described a case of metastasis of squamous cell carcinoma of the larynx in the gastrostomy site, and discussed the […]

ABSTRACT Objective: To gather information on penile cancer epidemiologic trends and its economic impact on the Brazilian Public Health System across the last 25 years. Methods: The Brazilian Public Health System database was used as the primary source of data from January 1992 to December 2017. Mortality and incidence data from the Instituto Nacional de Câncer José Alencar Gomes da Silva was collected using the International Classification of Diseases ICD10 C60. Demographic data from the Brazilian population was obtained from […]

ABSTRACT Spindle cell squamous cell carcinoma of the tongue is a rare variant of squamous cell carcinoma. This paper reports the case of a spindle cell squamous cell carcinoma of the tongue, in a 64-year-old male patient, and presents a review of the etiopathogenesis, clinicopathological and immunohistochemical features and treatment of the malignancy. The patient presented for evaluation of a painful swelling on his tongue. Extraoral examination revealed palpable submandibular and superior cervical lymph nodes. Based on the presumptive diagnoses […]

ABSTRACT Objective: Functional in vitro studies are fundamental to understand the role of microRNAs, small non coding RNA molecules that function as post-transcriptional regulators, in cancer. The objective of this study was to determine the applicability of head and neck squamous cell carcinoma cell lines and human oral keratinocytes as models for functional studies on microRNAs previously identified as deregulated in head and neck squamous cell carcinomas. Methods: The expression level of four microRNAs was assessed in cell lines and […]

ABSTRACT Objective: To evaluate the influence of lymph node reactivity on recurrence and survival rates in a population of pT3 or pT4 pN0 patients with laryngeal squamous cell carcinoma. Methods: Between 2002 and 2005, 105 patients with LSSC underwent total laryngectomy with bilateral selective neck dissection including levels II, III and IV. Most (69) received PO radiotherapy. All pathological specimens were either pT3 or pT4, and all necks were pN0. All lymph nodes were analyzed and their reactivity status were […]
