Objective: To present a rare case of Adenoid Cystic Carcinoma of the external ear canal in a 73-year-old man, including its diagnosis and surgical management. : Methods Design: Case Report Setting: Tertiary Government Training Hospital Patient: One Results: A 73-year-old man who consulted due to decreased hearing on the right ear had a 4-year history of gradually enlarging mass occupying the right external auditory canal. Wide en bloc resection of the external auditory canal mass and superficial parotidectomy with facial nerve preservation was performed with final histopathology results of adenoid cystic carcinoma. Follow-up at 2 years has shown no signs or symptoms or recurrence. Conclusion Adenoid cystic carcinoma of the external ear canal is a very rare disease that can present similarly to other otologic infections. Early identification of symptoms, performance of necessary imaging, and timely biopsy are key to reducing misdiagnosis and improving the survival rate. Complete resection of the tumor with adequate margins is the recommended treatment due to its high rates for recurrence.

A 27-year-old female patient suffering endolymphatic sac tumor with intralabyrinthine hemorrhage was reported. The patient had hearing loss in the left ear with continuous tinnitus, and MRI showed the soft tissue shadow of endolymphatic sac. Considering that the tumor involved semicircular canal and vestibule,endolymphatic cyst tumor resection was performed by labyrinth route. After surgery, there was no cerebrospinal fluid leakage and facial nerve function was normal. More importantly, enhanced MRI of temporal bone showed no tumor recurrence 1 year after surgery.

OBJECTIVES: The purposes of this study were to evaluate the clinical characteristics of temporal bone metastasis (TBM) and to determine whether the characteristics differed according to primary malignancy. METHODS: We retrospectively analyzed data on 20 patients diagnosed with TBM between January 2000 and January 2017. Demographics, the period from diagnosis of primary malignancy to TBM diagnosis, the period from TBM diagnosis to death, the type and staging of primary malignancy, otologic manifestations, and TBM sites were assessed. After the primary malignancies were divided into solid cancers and hematologic malignancies, each parameter was compared between the two groups. RESULTS: The most common primary malignancy with TBM was lung cancer (45%). The most common otologic symptoms and signs were facial palsy (30.5%) and hearing loss (30.5%). The temporal squama (23%) and the facial nerve (20%) were the most commonly involved. Most TBMs occurred late in the disease process after the primary malignancy first metastasized to other organs. Hematologic malignancies metastasized significantly more frequently to the external auditory canal and the middle ear/mastoid compared to solid cancers (P=0.001 and P=0.004, respectively). CONCLUSION: If otologic manifestations such as facial palsy and hearing loss are presented in patients at advanced stages of malignancy, TBM of primary malignancy should be suspected. In addition, hematologic malignancies tend to metastasize to the external auditory canal and the middle ear cleft more commonly than solid cancers do.

OBJECTIVES: Carcinomas of the external auditory canal (EAC) are rare, and management remains challenging. Previous studies seeking prognostic factors for EAC cancers included cancers other than carcinomas. In this study, we analyzed the treatment outcomes of, prognostic factors for, and survival rates associated with specifically squamous cell carcinoma (SCC) of the EAC. METHODS: A retrospective review of 26 consecutive patients diagnosed with SCCs of the EAC in a 10-year period was performed in terms of clinical presentation, stage, choice of surgical procedure, and adjunct therapy. Overall survival (OS) and recurrence-free survival (RFS) were calculated and univariate analysis of prognostic factors was performed. RESULTS: The median age of the 26 patients with SCCs of the EAC was 63 years (range, 40 to 72 years), and 16 males and 10 females were included. According to the modified University of Pittsburgh staging system, the T stages were T1 in 11, T2 in six, T3 in four, and T4 in five cases. The surgical procedures employed were wide excision in three cases, lateral temporal bone resection (LTBR) in 17, and extended LTBR in four, and subtotal temporal bone resection in two. Two patients underwent neoadjuvant chemotherapy, and two underwent adjuvant chemotherapy. One patient received preoperative radiation therapy, and eleven received postoperative radiation therapy. Of the possibly prognostic factors examined, advanced preoperative T stage and advanced overall stage were significant predictors of RFS, but not of OS. CONCLUSION: The advanced T stage and overall stage were associated with decreased survival after surgical treatment in patients with SCC of the EAC, highlighting the importance of clinical vigilance and early detection.
