Abstract Lymphoepithelial carcinoma is an undifferentiated carcinoma with nonneoplastic lymphoplasmacytic infiltrate, mostly located in the nasopharynx, while it is extremely rare in the oropharynx. We present a rare case of lymphoepithelial carcinoma arising from palatine tonsil. A 81-year old male patient complained of dysphagia, hypersalivation and bloody sputum. Clinical examination revealed hypertrophy of the right palatine tonsil and ipsilateral cervical lymphadenopathy. Biopsy and histopathological analysis confirmed the diagnosis of lymphoepithelial carcinoma. Multi-slice computed tomography showed a 33x31x38 mm heterodense mass in the region of the right palatine tonsil, and 37x30 mm and 21x20 mm lymph nodes on the right side of the neck. The patient was reffered to an oncology council, which suggested radiotherapy and concurrent chemotherapy. Although rare in clinical practice, lymphoepithelial carcinoma should be considered in cases of tonsil cancer.

Paragangliomas can be found from the skull base to the sacrum. Sinonasal paragangliomas are infrequent. A 16-year-old female reported spontaneous discrete bilateral epistaxis once a month beginning when she was 3 years of age. Computed tomography showed an expansive hypervascular mass occupying the right nasal cavity and nasopharynx. Sinonasal paragangliomas usually occur in middle-aged women. Radiologic investigation is essential for the diagnosis of sinonasal paragangliomas and evaluating extension of the lesion. Endoscopic and conventional approaches are effective, and preoperative embolization is paramount for reducing bleeding risk. Histopathological features cannot differentiate benign from malignant paragangliomas, and since metastasis may eventually occur, follow-up must be carried out for a long period of time.

Objective: To present a rare case of parathyromatosis. Methods: We present the clinical, laboratory, and imaging findings, along with a review of the literature. Results: A 33-year-old man with a history of right upper parathyroid adenoma removal 5 years prior due to hyperparathyroidism was admitted for severe hypercalcemia (15.6 mg/dL; normal, 8.5 to 10.5 mg/dL) with elevated plasma parathyroid hormone (PTH) (882 pg/mL; normal, 15 to 65 pg/mL). Ultrasound, computed tomography (CT), sestamibi, and positron emission tomography scans were unremarkable; however, a four-dimensional CT (4DCT) of the neck showed an area of increased signal enhancement and hypervascularity without discrete nodule in the posterior right thyroid region. The patient underwent parathyroid surgical exploration with right hemithyroidectomy and compartment neck dissection to remove the affected tissue. PTH levels dropped to 208 pg/mL postoperatively; calcium decreased but remained elevated at 12.7 mg/dL. Pathology revealed the presence of several small nodular foci of atypical hyperplastic parathyroid tissue in the right thyroid and soft tissue in the left central neck compartment consistent with parathyromatosis. Conclusion: This case report represents the first-time use of 4DCT to localize parathyromatosis. Parathyromatosis is a rare but problematic cause of recurrent hyperparathyroidism. Ultrasound and 4DCT may represent the best imaging modalities for identification and perioperative management to remove all affected tissue without reseeding.

<p>Epidermoid carcinoma is a frequent tumor in the upper aerodiodestive tracts, and depending on its location and tumor, nodes, metastases (TNM) stage, its therapy and prognosis vary enormously. Its location in the hypopharynx is rare, and in children or young adolescents, this location is extremely rare; The incriminated causes and the pathophysiology of the development of these tumors at this age remain a mystery. We present the case of a young patient of 13 years old, followed for squamous cell carcinoma of the right piriform sinus, with contralateral synchronous tonsil localization, and right lateral cervical lymphadenopathy fixed at 5 cm. In the absence of existing guidelines on the management of this type of location at this age, a multi-disciplinary meeting was necessary to decide on the management of this difficult case at this age.</p>

Lymphoepithelial cyst (LEC) is the most commonly encountered congenital neck pathology in the lateral part of the neck. A 66-year-old woman presented to the ENT clinic due to difficulty in swallowing persisting for approximately 1 year. Magnetic resonance imaging revealed a cystic mass at right tonsil. Surgery was performed due to this unilateral tonsillar mass, which was excised together with the right tonsil. LEC was diagnosed at histopathological examination. LEC in the palatine tonsil is rare, and only a few cases have been reported in the literature. We report a rare case of LEC in the palatine tonsil.

Aggressive Variant

Lymphoepithelial Carcinoma (LEC), an aggressive variant of Squamous Cell Carcinoma (SCC), is an undifferentiated carcinoma with an intermixed reactive lymphoplasmacytic infiltrate. Most cases of LEC occur in the nasopharynx, while it rarely involves other sites. LEC of larynx and hypopharynx is an extremely rare and aggressive neoplasm, characterized by a high propensity to loco-regional dissemination and a poor prognosis; it represents the 0,2% of all tumours of the larynx. Since it is such a rare tumor, the current literature provides only recommendations and there are no treatment guidelines available. A 70-year-old man with laryngeal LEC and both distant and nodal metastases was treated with chemotherapy, following EXTREME regimen therapy. It was classified as a cT3 N3b M1 glottic cancer (Stage IVC, AJCC 8th Ed.), stage IVC. As the response on metastases was unexpectedly encouraging, surgical treatment on T could be performed. Patient underwent to total laryngectomy and bilateral neck dissection. To date, eight months after surgery, the patient is disease free. The unusual clinical course is reported.

Abstract BackgroundMacrodystrophia lipomatosa is a rare nonhereditary congenital gigantism, characterized by overgrowth of mesenchymal and fibro-adipose tissue, affecting one or more digits of the extremities. Here, we report a rare case of macrodystrophia lipomatosa of the entire right lower limb with extension of hypertrophied fatty tissue into the abdominal wall and breast. Case presentationA 32 years old woman was born with abnormally elongated and thickened right leg, and the condition aggravated gradually. The disease was multiple, including the right leg, right abdominal wall, and the left breast were also involved. The patient mainly complained that she was unable to walk but with the knee flexed. Physical examination revealed that the elongation and thickening was proportional to the left leg, and the involved joints were malformed and dysfunction. X-ray and Computed tomography angiography (CTA) showed the bones and vessels were elongated and thickened, and the joints were hypertrophic and swollen. Amputation, volume reduction and liposuction was performed on the lesions. Histological examination could see abnormal fibro-fatty tissue hyperplasia, the adipocytes were invasive, and part of muscles presented fat degeneration. The lesions showed no recurrence for one year after surgery.ConclusionAfter reviewing the literature of the macrodystrophia lipomatosa, we believed that our case was rare because the hypertrophied fatty tissue extended into the abdominal wall and breast, which was different from former studies and had not been documented worldwide. This novel case will further deepens the understanding of this disease, and will be useful for clinicians in diagnosing it.

AbstractObjective:We present an extremely rare case of a 44-year-old woman with right gustatory otorrhoea and otalgia.Case report:The patient had been initially treated for otitis externa after Pseudomonas aeruginosa was grown from a microbiological swab. The otorrhoea fluid was collected and tested positive for amylase. Sialography and computed tomography imaging of the temporal bone confirmed a sialo-aural fistula from the right parotid gland to the bony external acoustic meatus. The defect was consistent with a patent foramen of Huschke. The fistula was identified surgically via a superficial parotidectomy approach, after contrast injection of Bonney's blue dye into the parotid duct, and then ligated and divided. The patient had immediate and sustained resolution of her otorrhoea.Conclusions:Sialo-aural fistulae are extremely rare, and usually arise as a complication of surgery or as an acquired disease process. To date, only four cases have been reported. This case demonstrates the use of sensitive investigation involving sialography and computed tomography, as well as successful surgical management, with complete resolution of symptoms.

Cranial Injury

A ten-month old, male Black and Tan Coonhound dog was referred with ocular bleeding due to gunshot injury. His mental state was normal. A computed tomography revealed that the bullet was planted in the left cranium. It was presumed that the trajectory of the bullet penetrated from the right medial angle of the eye to the orbit, and changed its track to caudo-dorsal by penetrating the cranium, ending up at the left cranium. The bullet was removed by lateral rostrotentorial craniectomy. No complications were observed during a one-year follow-up except the blindness in the right eye. This is a rare case of gunshot-induced traumatic brain injury featuring a bullet which went through the orbit into the cranium. The damaged frontal lobe seemed to show no neurological signs at the time of first examination in this case. In conclusion, a less aggressive surgical approach is recommended to remove bullets when they are accessible.
