Abstract Introduction/Objective Myoepithelial carcinoma is identified by nearly exclusive myoepithelial differentiation and evidence of malignancy. It may arise de novo or in preexisting benign tumors including pleomorphic adenoma and benign myoepithelioma. It occurs most commonly in the parotid gland followed by submandibular glands, minor salivary glands, and occasionally in the sublingual gland. Nasopharyngeal origin has been rarely reported. Methods/Case Report An afebrile 19-year-old female presented to the emergency department with persistent facial pressure, otalgia (right side greater than left side), rhinorrhea, and several episodes of epistaxis. One month before, she has been treated with Amoxicillin for three days with no relief, where Augmentin started for her for five days. About four days prior presentation, she was placed on Prednisone and Cefdinir. Over the next several days, she began having throat pain with difficulty swallowing. Routine blood work revealed a leukocytosis of 14.2 with normal differentiation. CT of the neck showed a large soft tissue mass centered at the right nasopharynx. Flexible nasal endoscopy performed bilaterally to reveal the nasopharynx is entirely obstructed with a lobulated mass filling the nasopharynx. On the right side, it extends into the posterior nasal passage filling the sphenoethmoid recess and the posterior floor of the nasal passage. Outpatient biopsy from nasopharynx mass is also performed. Results (if a Case Study enter NA) Mass biopsy reveals a mucinous and chondromyxoid background with mixed epithelial and myoepithelial differentiation. The is squamous metaplasia of myoepithelial cells and prominent mitotic activity and apoptotic activity. Immunohistochemistry was positive for CK5/6, calponin, BCL2, SMA, BerEp4, Sox10, and a proliferative index up to 40%. Based on this information Myoepithelial Carcinoma ex-pleomorphic adenoma of the nasopharynx is the diagnosis. Conclusion Carcinoma ex pleomorphic adenoma is usually a high-grade malignancy. It occurs most commonly in the parotid gland, followed by submandibular glands, minor salivary glands, and occasionally in the sublingual gland. Our case is one of the few cases of myoepithelial carcinoma arising in nasopharyngeal pleomorphic adenoma.

Cholesteatoma is a pathological tissue that may extend into all parts of temporal bone and rarely, as this study highlights, beyond its structures. Nevertheless, the spread outside the mastoid tip into the soft tissues of the neck or parotid space is very rare. The case of 23-year-old male with right parotid mass is presented. The patient had history (2006, 2009, and 2012) of three tympanoplastics for recurrent right ear cholesteatoma. The parotid tumor was revealed incidentally in magnetic resonance imaging in January 2016, but the imaging was inconclusive. After 6 months, the patient developed right-sided facial nerve palsy. The second look of the right ear was performed with simultaneous parotid surgery. The ear was healed and free of cholesteatoma, but the parotid mass resembled the cholesteatoma confirmed later on by histological examination. The tumor extended from stylomastoid foramen. This case was unusual as the disease had extended beyond the ear with the bony parts of the mastoid being preserved. To our knowledge, this is the first case report to describe a parotid gland cholesteatoma not being an extension of a cholesteatoma present in the tympanic cavity and entering the parotid gland via stylomastoid foramen.

Congenital unilateral agenesis of the parotid gland is a rare condition with only few cases reported in the literature. A review of 21 cases in the available literature is presented in this article. We report on a further case of a 34-year-old woman with agenesis of the left parotid gland and lipoma of the right cheek. Clinicopathological characteristics of described cases in the literature were discussed.

The facial nerve divides within the parotid gland into upper temporozygomatic and lower cervicofacial branches. The two branches further subdivide and emerge from the parotid gland as five main branches. We observed a rare anomalous branching pattern of the facial nerve along with double parotid duct on the right side of a 50-year-old male cadaver. The two parotid ducts emerged at the level of the anterior border of parotid gland then united to form one single duct thereby opened into the oral cavity. The first duct (D1) emerged from the upper one third of the anterior border of the parotid gland and traversed horizontally for 9 mm to join the second duct. Knowledge of anomalous branching pattern of facial nerve and double parotid ducts may be beneficial for maxillofacial surgeons.

Introduction: Lipomas among the most common benign neoplasms and rarely observed in parotid glands. We present a new case of lipoma in the superficial and deep lobes of the right parotid gland. Case report: A 52-year-old woman with painless and progressive inflation in the right preauricular region was referred to us. Computed Tomography scanning showed a hypodense area 5.2×4 cm in dimension in the right parotid gland region, and the facial nerve was fully exposed. The patient underwent parotidectomy, during which extensive removal of the mass was done. The pathology report cited a yellow-colored fatty tissue mass, 5×4×2 in dimension. In the microscopic report, lipoma of the parotid gland was seen.Conclusion: Determination of the exact tumor location is very important in the surgical approach in such cases. To our knowledge, this case seems to be an extremely rare case of lipoma in the superficial and deep lobes of the parotid. [GMJ. 2012;1(2):88-90]

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.
