“…Malignancies located in the abdomen can ascend via the thoracic duct into the head and neck. The right lymphatic duct drains from right half of the thoracic cavity, right side of the head and neck and right upper limb 5. The patient described in the case report also had other new metastases.…”

The patient presented to the ear, nose and throat clinic with failed conservative treatment of persistent right otitis externa. On examination, the roof of the right ear canal was polypoid and the tympanic membrane could not be visualised. There was a fragile mass noted in the external auditory canal (EAC) which on microsuction started to bleed. CT internal auditory meatus and MRI internal auditory meatus identified soft tissue mass in the EAC. The patient underwent urgent examination under anaesthetic of the ear and biopsies were taken. He had a background of ascending colon cancer; Duke’s C1, pT4, N1 M0, R0 resection and had undergone laparoscopic right hemicolectomy with adjuvant chemotherapy, in the previous year. The biopsy results proved that the mass in the EAC was due to metastatic deposit of colorectal primary tumour. The patient also had a full body CT which revealed other new metastases. The patient is being treated with palliative chemotherapy.

“…The common primary sites of metastasis to the temporal bone is breast followed by lungs, kidney. 9 Metastasis to the temporal bone is common in petrous temporal bone, internal auditory canal, mastoid process and is very rare in external auditory canal. 9 Our patient (case 1) had presented with history of profuse bleeding from the ear which can be explained by the rich vascularity of the metastatic renal cell carcinoma.…”

<p>We describe 3 rare cases of metastatic renal cell carcinoma in the head and neck region. Our first case was a 72 years old male presented with profuse bleeding from the left ear. On examination, proliferative, pink, friable mass was present in the left external auditory canal. On eliciting the detailed history, it was found that patient had renal cell carcinoma in the left kidney four years back and underwent left radical nephrectomy. Patient underwent left lateral temporal bone resection with cul-de-sac closure. Histopathological examination of the specimen showed metastatic renal cell carcinoma. Our second case was a 64 years old male presented with complaints of growth in the oral cavity of 1 month duration. On examination, 5×3 cms proliferative growth was present in the hard palate. Biopsy from the growth in the hard palate showed metastatic renal cell carcinoma. Patient gave history of renal cell carcinoma in the past for which he did not receive treatment. Our third case was a 45 years old male who presented to us with a diffuse swelling in the left temporal region of 2 months duration. On examination, 3×2 cms swelling was present in the left temporal region. Patient had history of renal cell carcinoma of left kidney and underwent left nephrectomy one year prior to the presentation of the left temporal swelling. Ultrasonography guided biopsy of the left temporal region showed metastatic renal cell carcinoma.</p>

“…Malignant tumor of EAC is very rare, and its incidence has been reported in decreasing order as follows: squamous cell carcinoma, basal cell carcinoma, adenocystic carcinoma, acinic cell carcinoma, mucoepidermoid carcinoma, and giant cell tumor of bone [1,2]. Metastatic tumor of EAC is exceedingly rare with only a few reported cases [3]. Prostatic adenocarcinoma (PA) is one of the most common malignancies in male population, and tends to metastasize to bones.…”

Background: Metastatic carcinoma manifesting as a mass in external auditory canal (EAC) is very rare, and prostatic adenocarcinoma (PA) presenting firstly as a mass of EAC has not been reported. Aim: To report a case of PA manifesting as only a mass of EAC. Case report: A 77-year-old man presented a right EAC mass. Otoscope identified a small mass approximately 7 mm in right EAC neat to the external orifice. Biopsy showed well differentiated adenocarcinoma with cribriform appearances. The author highly suspected metastatic prostatic PA (Gleason 4 + 4 = 8) and performed an immunohistochemical (IHC) study. The IHC showed positive prostate-specific antigen, prostatic acid phosphatase, alpha-methylacyl-CoA racemase, cytokeratin (CK) 7, and CK20. The tumor was negative for TTF-1, CDK2, and NCAM. The definite diagnosis of PA metastatic to EAC was made. The patient was referred to Urology and prostatic needle biopsy showed PA with immune-expressions of PSA, PAP, and AMACR. Serum PSA was high (63 ng/L). Imaging techniques showed a few metastases in bones of vertebula and ribs. The skull appeared free of metastasis, and head and neck soft tissue showed no metastatic areas except for the shadow of EAC. The patient is now treated with hormone and chemotherapy. Conclusion: The first case of an EAC mass that is a metastatic lesion of prostatic adenocarcinoma, was reported.

External Auditory Canal Mass as the First Manifestation of a Bronchogenic Carcinoma: Report of a Rare Case

Abstract: A patient with an aural mass presents a diagnostic dilemma. Metastatic tumors in the EAC are extremely rare, but they should be included in the differential diagnosis of a mass in this location.
