Management of an Atypical Lipomatous Tumor/Well-Differentiated Liposarcoma of the Left Laterocervical Region: Report of a Rare Case.

Liposarcomas are among the most usual cancerous growths of mesenchymal tissues and represent about 1% of head and neck sarcomas. They are extremely rare in childhood and are mostly seen between 30 and 60 years of age. The biologic behavior and histologic features of liposarcomas vary. Although these tumors grow very slowly and have a benign behavior, sometimes they grow rapidly and metastasize early, with fatal results. This case report presents a 63-year-old man with a tumor of the left side of the cervical region which has grown to a large size over four years. For an accurate diagnosis, fine needle aspiration biopsy (FNA) biopsy was performed. The cytological examination showed an adipose tumor. Surgical removal was done under local anesthesia and the pathologic examination showed a well-differentiated liposarcoma. These are usually early stage tumors, with fewer metastases than other sarcomas. Surgical abscission is the gold standard for the treatment of liposarcomas. The efficacy of postoperative radiotherapy or/and chemotherapy is controversial.

Pyogenic Granuloma Gravidarum of the Nasal Cavity Causing Recurrent Epistaxis. A Case Report and Review of the Literature.

Pyogenic granuloma is a benign proliferative fibrovascular lesion commonly arising from the skin and mucous membranes of the head and neck region. Histologically, this tumor is characterized by vascular proliferation and a circumscribed group of capillaries organized in lobules. It is usually located in the oral cavity and nasal location is less frequent. When it occurs in pregnant women, it is usually referred as pyogenic granuloma gravidarum. In this article we present the case of a pyogenic granuloma gravidarum in a young woman with intermittent epistaxis during the last trimester of pregnancy that did not resolve after childbirth and was treated with transnasal endoscopic resection and cautery at the base of the lesion for hemostasis under local anesthesia.

Seromucinous Hamartoma of the Lateral Nasal Wall with Infiltration of the Orbit: A Rare Case Report and Review of the Literature.

Seromucinous hamartoma is a rare benign glandular proliferation arising from the respiratory epithelium of the sinonasal tract and nasopharynx. It was described for the first time in 1974 by Baillie and Batsakis. Since then, few cases have been reported in the literature with most of them occurring in the posterior nasal septum. We report the case of a 52-year-old woman that presented to our department with left periorbital edema, pain, and dacryorrhea due to seromucinous hamartoma arising from the left inferior turbinate and extending through the lateral nasal wall into the maxilla, the nasolacrimal duct, and the orbit. Endoscopic medial maxillectomy and endoscopic transnasal orbital tumor resection were performed. The patient remains symptom-free for 16 months, till her most recent follow-up. Seromucinous hamartoma of the nasal cavity is an exceedingly rare diagnosis, especially in the lateral nasal wall. It should be included in the differential diagnosis of nasal tumors. According to the literature review, this is the first case report of seromucinous hamartoma with orbit infiltration. Endonasal endoscopic resection is the treatment of choice.

Hemorrhage of Upper Digestive and Respiratory Tracts in a Child with Glanzmann Thrombasthenia.

Glanzmann thrombasthenia (GT) is an autosomal recessive platelet disorder that could cause mild to severe bleeding episodes. The incidence is approximately 1 per 1,000,000 births. Patients with GT frequently have mucocutaneous bleeding with absent platelet aggregation in response to all physiologic stimuli, but a normal platelet count and morphology. Specifically, the glycoprotein IIb/IIIa (GP IIb/IIIa) complex is either inadequate or dysfunctional. This case reports a 3.5-year-old boy with Glanzmann thrombasthenia who had two episodes with uncontrolled hemorrhage from upper digestive and respiratory tracts, the first with the bleeding point found in the left tonsil and the second in the adenoids.

Resection of Primary and Recurrent Parapharyngeal Space Pleomorphic Adenomas via a Combined Transcervical-Transparotid Approach: A Case Series.

Primary parapharyngeal space tumors are rare, and due to the complex anatomy of the parapharyngeal space, their diagnosis and treatment are challenging. Pleomorphic adenoma is the most common histologic type followed by paragangliomas and neurogenic tumors. They can present as a neck lump or an intraoral submucosal mass with the displacement of the ipsilateral tonsil or might be asymptomatic and discovered incidentally on imaging obtained for other reasons. Magnetic resonance imaging (MRI) with gadolinium is the imaging of choice. Surgery remains the treatment of choice and many approaches have been described. In this study, we present three patients with PPS pleomorphic adenoma (two primary and one recurrent), which were resected successfully with a transcervical-transparotid approach without mandibulotomy. Division of the following anatomical structures: the posterior belly of the digastric muscle, stylomandibular ligament, stylohyoid muscle and ligament, and styloglossus muscle is a very important tip for the surgeons because enables displacement of the mandible providing excellent exposure for complete tumor excision. The only postoperative complication was temporary facial nerve palsy in two patients who fully recovered within two months. The aim of this mini case series is to present our experience, together with some tips and benefits of the transcervical-transparotid approach for the resection of pleomorphic adenomas of the PPS.

Differential Diagnosis of Cervical Lymph Nodes with Ultrasound and Virtual Touch Imaging Quantification: a Report of Three Cases.

Cervical lymphadenopathy is a common clinical presentation, and its differential diagnosis is challenging. In this article we present three cases with enlarged cervical lymph nodes evaluated with combination of ultrasound (US) and virtual touch imaging quantification (VTIQ) performed by the head and neck surgeon G.P. with a 10-year experience in ultrasound elastography (USE). In the first two cases, US and VTIQ evaluation showed predominance of areas with increased stiffness and higher share wave velocities compared with those in the third case. Malignancy was suspected in the first and second cases. The histology report revealed metastatic squamous cell carcinoma in the first two cases and chronic non-specific lymphadenopathy in the third case. The development of VTIQ share wave elastography has improved the diagnostic accuracy of ultrasonography and can guide clinical decision when dealing with cervical lymphadenopathy.

Management of an Acute Airway Obstruction Due to Tracheal Carcinoma in a Patient With Severe Glottic Stenosis.

In this paper, we present the case of acute airway obstruction due to tracheal carcinoma in a patient with glottic stenosis due to previously treated laryngeal carcinoma. Because of severe dyspnea from the obstructive endotracheal mass, tracheotomy under local anesthesia was immediately performed. Intubation with pediatric size (I.D. 4.5 mm) cuffed endotracheal tube was performed by the surgeon through tracheostomy under endoscopic visualization. Blakesley forceps and electrocautery were used for tumor debulking. Postoperatively there were no complications and the patient was discharged after four days. The histopathology report showed a squamous cell carcinoma. The tumor board decided on adjuvant chemoradiotherapy for the treatment of the patient.

A Study of Airborne Pollen Grains and Fungal Spores in the Region of Epirus (Northwestern Greece).

INTRODUCTION: In the region of Epirus (Northwestern Greece) there are characteristic climatic and geographical conditions that facilitate the growth of typical vegetation with the production of allergic pollen. Aerobiological research into airborne pollen diversity and seasonal variation in pollen counts and fungi spores has become essential due to the growing incidence of allergic rhinitis, allergic asthma, and other pollen-related and spore-related allergic conditions. Furthermore, weather conditions and other factors like air pollution may affect the intensity, the onset, and the duration of the pollen season, and the impact on the patient's symptomatology. METHODS: The diversity of airborne pollen grains (grains/m3) and fungal spores (spores/m3) in the region of Epirus were measured volumetrically using Burgard trap for 13 months, from May 1, 2017 to May 31, 2018. RESULTS: Totally, 10 pollen families and two fungi were recognized. The six most common taxa were Cupressaceae, Pinaceae, Urticaceae, Poaceae, Betulaceae, and Compositeae. The fungi taxa were Cladosporium and Alternaria. Peak pollen centralization was recorded from May to September. Urticaceae had the longest pollen season while Oleaceae and Pinaceae had the shorter. Fungal spores were recorded during all the months of the year. Also, there was a correlation between meteorological parameters and most pollen taxa. CONCLUSION: The pollen and spore calendar shows the concentration of pollen grains and fungal spores in the region of Epirus. This knowledge is important for physicians and allergic patients as it could improve the management of the allergic respiratory disease.

Primary Cutaneous Anaplastic Large Cell Lymphoma of the Nasal Dorsum and Nasal Tip.

Primary cutaneous anaplastic large-cell lymphoma (C-ALCL) is described as a non-Hodgkin lymphoma that affects only the skin, with no evidence of an extracutaneous disease during the first six months following the diagnosis. We present an unusual case of a 53-year-old man with developed fever and a rapidly increasing ulcerated skin lesion located on the nasal dorsum and nasal tip. The nasal endoscopy revealed a reddish polypoid lesion over the anterior edge of the superior turbinate which had extended through the roof of the nasal cavity in the adjacent area of the nasal septum.

Parenchymal Brain Abscess as an Intracranial Complication After Sinusitis.

Brain abscesses caused by sinusitis are rare in the antibiotic era. The purpose of the current manuscript was to report a rare case of a brain abscess located mainly in the frontal lobe after sinusitis, which was initially thought to be meningitis or encephalitis. A 39-year-old man was transferred to our hospital from another neighbouring hospital with tonic-clonic seizures, severe headache, and purulent nasal secretions. For one week, he was taking antibiotics for sinusitis. The computed tomography indicated lesions in the right sinuses but not in the parenchymal brain and thus antibiotics along with antiepileptic drugs were given. However, due to the deterioration of symptoms, magnetic resonance imaging was executed, which revealed an abscess in the frontal lobe. Afterward, an anterior ethmoidectomy and middle maxillary antrostomy were performed in order to drain the purulent content from the right sinuses. Ten days later, the patient presented disorientation and thus an open craniotomy for successful removal of the parenchymal abscess was performed. One month later, the patient was discharged with mild irritability, which was eliminated gradually over the next two months. Conclusively, brain abscesses can be caused by local spread from an infection of the paranasal sinus. The contribution of imaging modality is very significant not only for the early diagnosis but also for the therapeutic management of such cases. Frequently antibiotic treatment is insufficient and surgery may be required.

Intraoperative flow cytometry for head and neck lesions. Assessment of malignancy and tumour-free resection margins.

Head and neck cancer poses a significant health problem worldwide. We set out to investigate the value of rapid intraoperative cell cycle analysis by flow cytometry for the intraoperative characterization of head and neck lesions and surgical margins. Seventy patients with head and neck lesions suspicious of malignancy were included in the study. There were 31 neoplastic and 39 benign lesions. Flow cytometry permitted the intraoperative detection of neoplastic lesions within 6 min with high sensitivity and specificity based on cell cycle fractions. In the cases in which surgical margins were assessed, intraoperative flow cytometry had complete concordance with pathology. Intreoperative flow cytometry is a novel promising technique for rapid intraoperative characterization of malignancy and tumour free resection margins in head and neck lesions.
