BACKGROUND: Recent studies have shown an increasing incidence of cutaneous adnexal carcinomas (CACs) over the years. OBJECTIVE: The aim of our study was to evaluate incidence and survival of CACsand investigate their association with other skin neoplasms. METHODS: Population based study. Data on incident cases of CACs were obtained from the Tuscany Cancer Registry (TCR) between 1985 and 2010. In order to determine if the occurence of squamous cell carcinoma (SCC) among patients with CAC is higher or lower than expected in the general population, standardized incidence ratio (SIR) was calculated...

Schwannoma is usually an uncommon benign encapsulated slow-growing neural tumor that originates from Schwann cells of peripheral, cranial, and autonomic nerves. It constitutes 1% to 8% of all head and neck neoplasms. Extracranial schwannoma are very rarely seen originating from the infraorbital nerve. Most of the schwannomas are usually solitary and not associated with NF1. The typical presentation is a slow-growing soft-tissue mass. Treatment of schwannoma is surgical resection.

The expression of proinflammatory cytokines in various malignant neoplasms is widely considered to represent the host immune response to tumor development. The role of interferon (IFN)γ in head and neck squamous cell carcinoma, and its association with endoplasmic reticulum (ER) stress pathways, remains a subject of ongoing investigation. Dentin sialophosphoprotein (DSPP), which is a member of the small integrin‑binding N‑linked glycoproteins family, has been implicated in malignant transformation and invasion of oral squamous cell carcinoma (OSCC)...

Sinonasal non-intestinal-type adenocarcinoma (non-ITAC) is a rare, morphologically diverse neoplasm of the head and neck. Squamoid morular metaplasia has recently been reported as an occasional finding in non-ITAC. Interestingly, these squamoid morules often show aberrant expression of CDX2 as well as nuclear expression of β -catenin, similar to other tumors that show this type of metaplasia, but the underlying mechanism responsible for this finding is not completely understood. We present two cases of low-grade non-ITAC with squamoid morules coexpressing CDX2 and nuclear β -catenin by immunohistochemistry, both of which were found to harbor a mutation in CTNNB1 , the gene encoding β -catenin...

PURPOSE OF REVIEW: Recurrent respiratory papillomatosis (RRP) is the most common as well as the costliest benign airway neoplasm in the United States [Ivancic et al. (2018). Laryngoscope Investig Otolaryngol 3:22; Derkay (1995). Arch Otolaryngol Head Neck Surg 121:1386]. In addition, it is potentially deadly, with risk of airway obstruction as well as a 3-7% risk of malignant conversion [Schraff et al. (2004). Arch Otolaryngol Head Neck Surg 130:1039]. This review highlights exciting advancements over the past 1-2 years in scientific understanding of the pathophysiology, epidemiology, natural history, prevention, and treatment of this difficult disease...

Papillary thyroid carcinoma (PTC) arising within follicular adenoma is a rare histological subset of papillary carcinoma. A 24-year-old female (euthyroid and asymptomatic) presented with a solitary mass in the right lobe of thyroid for 2 years. Fine-needle aspiration cytology (FNAC) suggested features of hyperplasia of thyroid. Hemithyroidectomy was performed. Histopathological examination revealed two distinct areas and was reported as encapsulated variant of papillary carcinoma along with follicular adenoma...

Adamantinoma-like Ewing sarcoma (ALES) is a rare tumor that demonstrates the EWSR1-FLI1 translocation characteristic of Ewing sarcoma despite overt epithelial differentiation including diffuse expression of cytokeratins and p40. Most cases of ALES described to date have occurred in the head and neck where they can mimic a wide range of small round blue cell tumors. Because distinguishing ALES from basaloid salivary gland carcinomas can be particularly difficult, we analyzed a series of 10 ALESs that occurred in the salivary glands with the aim of identifying features that allow for better recognition of this entity...

Rhinosporidiosis is a communicable disease prevalent in tropical countries that affects one or more mucocutaneous sites such as the nasal cavity, pharynx, skin, bronchus, genitals, and bone, in isolation or together. We report a case of multicentric rhinosporidiosis involving the nasal cavity, oropharynx, larynx, and cheek skin without disseminated disease outside the head and neck. Although the appearance of mucocutaneous lesions in our patient was similar to that of papilloma or neoplasm, the distinct clinicopathologic characteristics of the rhinosporidiosis guided us in managing the case successfully...

Cellular neurothekeoma is a benign cutaneous neoplasm that typically occurs on the head, neck, and upper body of young adults with a slight female predominance. It is a rare lesion to diagnose and multiple neurothekeomas in one patient is an even more uncommon finding. We present a case of multiple neurothekeomas in a middle-aged woman with lower extremity involvement and summarize the current literature on multiple neurothekeoma patients. A 46-year-old female presented with nearly one dozen skin-coloured papules on the head, upper limb, and lower limb...

Feline oral squamous cell carcinomas (FOSCC) are highly aggressive neoplasms with short survival times despite multimodal treatment. FOSCC are similar to squamous cell carcinomas of the head and neck (SCCHN) in humans, which also present therapeutic challenges. The current study was undertaken to identify novel chemotherapeutics using FOSCC cell lines. A high throughput drug screen using 1,952 drugs was performed to identify chemotherapeutics for further investigation. Two of the drugs identified in the drug screen, actinomycin D and methotrexate, and two drugs with similar molecular targets to drugs found to be efficacious in the screening, dinaciclib and flavopiridol, were selected for further investigation...

Paragangliomas are neuroendocrine neoplasms, derived from paraganglia of the sympathetic and parasympathetic nervous systems. They are most commonly identified in the head and neck, being most frequent in the carotid body, followed by jugulotympanic paraganglia, vagal nerve and ganglion nodosum, as well as laryngeal paraganglia. Abdominal sites include the well-known urinary bladder tumors that originate in the Organ of Zuckerkandl. However, other unusual sites of origin include peri-adrenal, para-aortic, inter-aortocaval, and paracaval retroperitoneal sites, as well as tumors in organs where they may not be expected in the differential diagnosis of neuroendocrine neoplasms, such as thyroid, parathyroid, pituitary, gut, pancreas, liver, mesentery, lung, heart and mediastinum...

INTRODUCTION: Parapharyngeal space (PPS) is the anatomical area lateral to the upper pharynx and clinically important due to PPS tumors. They account for less than 1% of head and neck neoplasms. Both benign and malignant neoplasms may arise there and typical for this localization is diversity of histological origin. Complete surgical excision is still the basis of treatment. AIM OF THE STUDY: Evaluation of the results of surgical treatment of PPS tumors in the Department of Otolaryngology at the Medical University over the period 2015-2017...

Background: Field cancerization is a phenomenon in which prolonged exposure to carcinogens induces changes throughout the epithelium leaving the field ready for the appearance of premalignant or malignant lesions. These alterations can promote the development of multiple carcinomas and explain the appearance of recurrences and second primary tumors. The objective of this study was to report the case of a patient who developed six oral cavity tumors in five years of treatment and, also, demonstrate the immunohistochemical changes for p53 and Ki-67, routinely used to assess dysplasic regions...

Liposarcoma of the larynx is a rare entity, typically well differentiated with a good prognosis. We present a patient who presented to ENT clinic with a 3-month history of hoarseness. Contrast-enhanced computed tomography of the neck demonstrated a 2.5-cm mass of the true vocal cord, which biopsy demonstrated to be dedifferentiated liposarcoma of the larynx. The patient went on to total laryngectomy with planned adjuvant radiation therapy. The presentation and imaging findings of laryngeal liposarcoma are nonspecific, but this neoplasm should be considered in the differential of masses in the head and neck...

Rhabdomyosarcoma is a malignant neoplasm of mesenchymal cells, showing varying degrees of striated muscle cell differentiation. It predominantly occurs in children while rarely found in adults and involvement of the oral cavity accounts for only 10%-12% of all head-and-neck cases. Herewith, we present a rare case of spindle cell rhabdomyosarcoma in a 52-year old male, involving the mandibular gingiva, and describe the clinical, radiological, histopathological and immunohistochemical findings.
