Leiomyosarcoma of the Middle Ear and Temporal Bone

Leiomyosarcoma is a malignant tumor of smooth muscle origin. It is rarely encountered in the head and neck area. A patient with leiomyosarcoma of the middle ear and the temporal bone with unusual bone destruction is presented. To our knowledge it is the first report of a middle ear and temporal bone leiomyosarcoma.

Introduction. Tuberculous otitis is a diagnostic problem due to the difficulty to obtain microbiological, histomorphological and cytological confirmation of the disease. Objective. Our objective was to compare clinical and radiological characteristic and development of otogenic complications in patients with tuberculous otitis and otitis with cholesteatoma as the most destructive form of chronic nonspecific otitis in the purpose of establishing the diagnostic criteria for tuberculous otitis. Methods. Medical records of 12 patients with tuberculous otitis and 163 patients with cholesteatoma treated at the Institute of Otorhinolaryngology and Maxillofacial Surgery in Belgrade during the eight-year period were analyzed. All of the patients underwent otomicroscopic, audiological and radiological examination of the thorax and temporal bone, microbiological examination of the secretion and histomorphological examination of the tissue taken during middle ear surgery. Statistical analysis was done using ?2 test with Yates correction. Results. Otogenic complication as facial palsy and sensorineural hearing loss were more frequent in tuberculous otitis patients, than in cholesteatoma. Also, fistulas of the labyrinth and facial canal bone destruction were also more frequent in tuberculous otitis than in cholesteatoma. A larger extent of temporal bone destruction was noticed on CT scans of the temporal bone in half of the patents with tuberculous otitis. Coexistence with miliary pulmonary tuberculosis was detected in one third of the patients. There were no microbiological or histomorphological confirmations of the disease, except in one case with positive Ziehl-Neelsen staining. Conclusion. Tuberculous otitis media should be considered in patients with serious otogenic complications and with shorter duration of ear discharge, and in association with diagnosed miliary pulmonary tuberculosis and extensive temporal bone destruction. Polymerase chain reaction still is not reliable for diagnosis.

Liposarcoma is a very rare malignant tumor affecting the head and neck area. Since it is an invasive and life-threatening disease, active treatments is necessary. However, differential it from lipoma, its corresponding benign counterpart, may be difficult. Herein, we report a rare case of posterior neck myxoid liposarcoma in a 72-year-old man who was initially misdiagnosed with lipoma, including a literature review of differential diagnosis between lipoma and liposarcoma.

Abstract Introduction This pilot study explores whether a human Thiel-embalmed temporal bone is suitable for generating an accurate and complete data set with micro-computed tomography (micro-CT) and whether solid iodine-staining improves visualization and facilitates segmentation of middle ear structures. Methods A temporal bone was used to verify the accuracy of the imaging by first digitally measuring the stapes on the tomography images and then physically under the microscope after removal from the temporal bone. All measurements were compared with literature values. The contralateral temporal bone was used to evaluate segmentation and three-dimensional (3D) modeling after iodine staining and micro-CT scanning. Results The digital and physical stapes measurements differed by 0.01–0.17 mm or 1–19%, respectively, but correlated well with the literature values. Soft tissue structures were visible in the unstained scan. However, iodine staining increased the contrast-to-noise ratio by a factor of 3.7 on average. The 3D model depicts all ossicles and soft tissue structures in detail, including the chorda tympani, which was not visible in the unstained scan. Conclusions Micro-CT imaging of a Thiel-embalmed temporal bone accurately represented the entire anatomy. Iodine staining considerably increased the contrast of soft tissues, simplified segmentation and enabled detailed 3D modeling of the middle ear.

Medial Maxillectomy

Angiosarcomas are rapidly growing malignant neoplasms arising from the vascular endothelial cells. Most common sites are the extremities and the retroperitoneal space, with only four per cent of angiosarcomas arising in the head and neck area, whilst the paranasal sinuses are one of the rarest locations. We report the case of a maxillary sinus angiosarcoma in a 72-year-old male patient. The first biopsy was inconclusive, whereas the second revealed an angiosarcoma. Medial maxillectomy was performed with subsequent external irradiation.
