Hypoglossal nerve palsy (HNP) is a common finding in neurologic diseases when associated with other cranial nerve palsies or further pathology and exhibits characteristic clinical manifestations, including unilateral atrophy of the musculature of the tongue. It occasionally appears as the initial or solitary sign of an intracranial or extracranial space-occupying lesion, head or neck injury, or vascular abnormality of the internal carotid artery. There are few cases of idiopathic isolated unilateral HNP, which should be diagnosed through exclusion...

Canine Leishmaniasis is a disease endemic in many parts of Europe, carried by insects of phlebotomous species. Humans are occasional hosts of the parasites. Cases of human leishmaniasis have been registered in Italy, particularly in the southern and coastal regions. In the period 1997-2016, we collected a series of 35 patients affected by cutaneous leishmaniasis, uncovered by skin biopsy and histological examination, 21 of them found in last 3 years. The patients, 28 males and 7 female, aged between 19 and 91, resided in a restricted area of Northern Italy, and none, but two, had travelled abroad...

The surgical pathologist plays a crucial role in the multidisciplinary team. In nearly all cases, a tissue diagnosis is required to confirm the disease process before treatment begins. Even in settings where the diagnosis appears straightforward, a timely and appropriate report is necessary. The pathologist is also responsible for providing many of the more specific data elements that will guide treatment decisions: examples include evidence of virally driven malignancy, margin status, and the precise depth to which tumor invades...

BACKGROUND: The laryngeal framework provides a natural barrier preventing tumour spread to extralaryngeal structures. Transoral laser microsurgery (TLM) for laryngeal squamous cell carcinoma (SCC) may violate these boundaries, altering the pathways of tumor spread for potential recurrences. Our project objective is to describe laryngeal SCC recurrence patterns and overall survival in patients requiring total laryngectomy (TL) after TLM. METHODS: Patients undergoing TLM for laryngeal SCC requiring salvage TL were identified from a prospective CO2 laser database containing all patients undergoing TLM for head and neck malignancies at the QEII Health Sciences Center in Halifax, Nova Scotia between March 2002 - May 2014...

Granular cell tumors are uncommon, usually benign neoplasms, mainly observed in the head and neck region, chest wall and upper extremities. These tumors account for ~0.5% of all soft-tissue tumors. Less than 2% are malignant. These are associated with poor prognosis. Clinical signs suspicious for malignancy are large size, rapid growth, invasion, recurrence and metastasis. Malignancy is confirmed by histological examination. We present the case of a 79-year-old patient with a 6-month history of a rapidly growing mass in the left gluteal region giving the clinical impression of a malignant tumor...

Background: Benign aggressive bone lesions of the femoral head and neck are mostly seen in young adults and warrant treatment for pain, impending fracture or established fracture, and disease clearance. It becomes challenging to treat them effectively while attempting salvage of the femoral head and yet achieving long term disease control with minimum complications. We describe our technique and experience in dealing with these lesions which can achieve the above-mentioned goals and can be easily replicated...

Osseous choristomas are rare benign lesions characterized by ectopic bone formation in the soft tissue of the head and neck region. Dermoscopy visualizes the morphological characteristics that are not observable by the naked eye, and may be used for the evaluation of calcification under the skin. The present study reports a case of an osseous choristoma arising in the tongue, and reveals the dermoscopic features of osseous choristoma from a surgical specimen. A 7-year-old boy was referred to the Department of Dentistry and Oral Surgery, with an asymptomatic pedunculated mass in the tongue...
