AbstractChondroblastoma represents approximately one per cent of all primary bone tumours. It is even rarer in the temporal bone and so far only 34 cases have been reported. We report here two cases with chondroblastoma of the temporal bone. The first case was discovered as a small lesion of the attic and root of zygoma. It was removed via mastoidectomy and reconstruction of the bony defect achieved normal external ear canal anatomy and hearing post-operatively. The second case presented as an advanced tumour involving the infratemporal fossa and parapharyngeal space. It was treated surgically via the infratemporal fossa approach. As clear surgical margins were not obtained, post-operative radiotherapy was also given to minimize the chance of recurrence.

First Case

Abstract Myxomas are mesenchymal origin, benign tumor, constituting approximately half of the benign cardiac tumors. Occasionally, it may also occurs at other locations, though the intracranial location of a myxoma is considered exceptionally rare. Only isolated few cases of intracranial myxoma are reported in the literature, almost all were locally confined within the originating bone. The extensive Pubmed and Medline search yielded only eight cases of primary myxoma arising in the temporal bone with extension into intracranial compartment. However intracranial extension is limited as early detection, however, Osterdock et al reported a case also arising from temporal bone with extensive intracranial extension. Author report an interesting case of intracranial myxoma in 27- year- old- male, involving the temporal bone associated with extensive bony erosion and also extending into infratemporal fossa, mastoid, and frontoparietal region and a polypoidal mass protruding into external ear. To the best of knowledge of authors, temporal myxoma presenting with external ear polypoidal mass, which underwent successful surgical excision is not reported and represent first case in the world literature.

Neural Sheath

Schwannoma or neurilemmoma is a common soft tissue neoplasm arising from the neural sheath of Schwann cells. However, intraosseous schwannoma is rare, accounting for less than 0.2% of primary bone tumours. Several variants of schwannoma have been reported; among them, intraosseous schwannoma with ancient change is extremely rare. This current report presents an extremely rare case of ancient intraosseous neurilemmoma. The patient presented with right elbow pain and disability. A radiolucent, well-defined, lobulated lesion with a thin sclerotic rim in the proximal ulnar metaphysis that had caused a pathological fracture was noted. The mass was surgically excised using marginal resection and bone curettage was undertaken. The bone deficit was grafted with hydroxyapatite and β-tricalcium phosphate and augmented with bone cement. There were no signs of any recurrence after 3 years. This is the first case of an ancient intraosseous schwannoma of the proximal ulna. Although rare, intraosseous schwannoma should be considered in the differential diagnosis of radiographically benign-appearing osseous tumours in the bone. The cement technique is recommended for the treatment of intraosseous schwannoma.

The Mean

The mean rupture pressure of the porcine tympanic membrane (TM) was measured in 9 specimens. Pressure was delivered gradually into the external ear canal of an excised piece of temporal bone, via a syringe and polyurethane tubing attached to the canal. Tympanometry was used to ascertain the structural integrity of the TM before pressure delivery. Rupture pressure was defined to be that point at which a sudden drop occurred in the overpressure in the ear canal, as measured by a pressure gauge. From the results, we concluded that the mean rupture pressure for the porcine TM is 1.2 ± 0.3 atm. This is of the same order of magnitude as and slightly less than pressures obtained for the human TM.

Introduction: Turicella otitidis, described as a new species over 20 years ago, has been isolated mainly from the external ear canal and middle ear fluid. Here, we report the first case of palmoplantar eczema related to T. otitidis. Case presentation: Here, we report the first case of palmoplantar eczema in a 74-year-old female related to T. otitidis. Conclusions: The question as to whether T. otitidis is a potential pathogen in cases of dyshidrotic eczema is still open, but this could be better elucidated if corynebacteria were speciated more often.

AbstractThe manifestations of multiple myeloma are protean and related to bony osteolytic lesions, and to medullar and renal insufficiency. We report a patient who presented with otalgia as the inaugural symptom of multiple myeloma. Local irradiation combined with systemic chemotherapy led to the disappearance of the temporal bone mass and the accompanying symptoms. To date, 24 months after the diagnosis, the patient is still in remission.The literature on otological involvement in multiple myeloma is reviewed. Symptoms are non-specific and include hearing loss, tinnitus, dizziness, facial paralysis, and otalgia. The diagnosis of multiple myeloma should be considered in the presence of a temporal bone mass.

Temporal Bone Tumor

Background: Carney complex (CNC) is a rare autosomal dominant syndrome, manifesting mainly with cardiac, cutaneous, and mucosal myxomas. Osteochondromyxoma is known as an extremely rare bone lesion of CNC which usually appears early in life; however, there were no reports of primary bone myxoma of the skull in the patients with CNC. We present the first case of primary myxoid skull tumor in the patient with CNC. Case Description: We report the left temporal bone tumor with significant intracranial mass effect in a 58-year- old woman already diagnosed with CNC. Complete resection of the tumor with skull bone reconstruction was carried out. Pathological diagnosis was labeled the lesion as an atypical myxoid spindle cell neoplasm. The features were different from atrial myxoma and osteochondromyxoma which has been described in CNC. There have been no signs of recurrence in 9 years follow-up. Conclusion: To the best of our knowledge, there have been no reports of the primary myxoid tumors in the skull in the patients with CNC. This paper highlighted a possible important association between CNC and primary intracranial myxoid tumors.

Yolk sac tumor (endodermal sinus tumor) is rarely encountered in the temporal bone. Facial nerve paralysis can be a primary manifestation of this condition. Histologically, the tumor can be difficult to diagnose, although elevated levels of alpha fetoprotein can facilitate its identification. In this report, we describe the case of an 18-month-old girl who developed peripheral VIIth nerve palsy and a polypoid mass in the left external ear canal 3 months following myringotomy. Computed tomography and magnetic resonance imaging revealed that the tumor involved the left external ear canal, middle ear space, and mastoid air cells. Biopsies were consistent with a yolk sac tumor. Special staining demonstrated that only a very few tumor cells were positive for alpha fetoprotein, despite the markedly elevated level of alpha fetoprotein in her serum. The patient was treated with chemotherapy, which included cisplatin, etoposide, and bleomycin. Within a period of weeks, she experienced a complete reversal of her left VIIth nerve palsy, a marked decrease in her serum alpha fetoprotein levels, and a dramatic resolution of the tumor as demonstrated radio graphically. Such a successful chemotherapeutic response in this case argues against surgical intervention in other cases, particularly in view of the risk of serious complications with surgery.
