Ceruminous Adenoma: A Rare Mass that Impair Hearing

Ceruminous adenoma is described as a glandular neoplasm of ceruminous glands. It is seen for less than one percent of all external ear tumours. Ceruminous adenoma cases were reported to have recurrence and residual tumour, however there was no malignant transformation known in ceruminous adenoma up to this date. Here, we report a young adult woman with two years history of progressive reduced hearing and tinnitus of the right ear. She was proven to have right moderate conductive hearing loss with pure tone audiometry. There was a cystic mass with serous content arising from the posterior wall of the right ear canal. We proceeded with wide local excision of the mass via trans-canal approach. Ceruminous adenoma was confirmed with histopathology and immunohistochemistry of CK7 staining. The hearing impairment was resolved completely post excision and there was no recurrence of the tumour on one year follow-up. We concluded wide local excision with appropriate margin of the mass is adequate to prevent recurrence in ceruminous adenoma cases.

Apocrine Adenoma of the External Auditory Canal with Pseudoepitheliomatous Hyperplasia

The tumors derived of the ceruminous gland in the external auditory canal are rare. Here, we report a case of a ceruminous adenoma (apocrine adenoma) with refractory chronic inflammation in the external auditory canal. A 46-year-old man presented with otorrhea, itching, and a foreign body sensation in his right ear. A soft reddish protruding lesion was revealed at the posterosuperior portion of the entry to the right external auditory canal by otoscopy. The skin lesion was endaurally resected; histopathology showed luminal structures in the middle to deep layer of the epidermis and inflammatory granulation below pseudoepitheliomatous hyperplasia. The walls of the luminal structures consisted of inner luminal secretory cells featuring apical decapitation secretion and outer myoepithelial cells. The patient was diagnosed with an apocrine adenoma. Three years after surgery, there has been no evidence of recurrence. Complete resection, including the deep layer of the epidermis, is necessary.

Feline ceruminous cystomatosis pada kucing persia 7 tahun

<em></em><em>Feline ceruminous cystomatosis </em>(<em>ceruminous adenoma</em>,<em> apocrine cystadenomatosis</em>) adalah kelainan nonneoplastik dan tidak umum yang terjadi pada kucing. Kucing Persia berusia 7 tahun datang ke My Vets Animal Clinic di Kemang Selatan dengan keluhan ada kutil-kutil hitam di sepanjang kedua daun telinga. Tindakan bedah berupa pengangkatan dipilih untuk menangani <em>feline ceruminous cystomatosis </em>tersebut dengan teknik ablasi saluran telinga vertikal sebagai pilihan. Ablasi terhadap kista menggunakan laser karbon dioksida adalah metode penanganan<em> </em>yang lebih dipilih, namun tindakan bedah berupa pengangkatan total pernah menjadi terapi<em> </em>pilihan. Hasil persembuhan luka jangka panjang pascabedah pada <em>feline ceruminous cystomatosis </em>menunjukkan hasil yang cukup bagus.

Ceruminous adenoma mimicking otitis externa

Ceruminous adenoma is an extremely rare condition that arises in the external auditory canal. The right ear canal in a 32-year-old man was obstructed by a ceruminous adenoma mimicking otitis externa and its symptoms. The lesion was resected under microscopic view using a transcanal approach. There were no tumor-related symptoms postoperatively and he has been disease free for 1 year after surgery.

Ceruminous Adenoma of the External Auditory Canal: A Case Report with Imaging and Pathologic Findings

Ceruminous adenomas are benign tumors that are rare in humans and present with a nonspecific symptomatology. The treatment of choice is surgical excision. We present an 87-year-old woman who presented with a reddish, tender, round, soft mass of the outer third of the inferior wall of the left external auditory canal, discharging a yellowish fluid upon pressure. Coincidentally, due to her poor general condition, this patient also showed symptoms consistent with chronic otitis media, parotitis, and cervical lymphadenopathy, such as otorrhea, through a ruptured tympanic membrane and swelling of the parotid gland and cervical lymph nodes. The external auditory canal lesion was surgically excised under general anesthesia, utilizing a transmeatal approach. The pathological diagnosis was ceruminous gland adenoma. The tumor was made of tubular and cystic structures and embedded in a fibrous, focally hyalinized stroma. Immunohistochemistry confirmed the presence of two distinct cell populations. The luminal cells expressed keratin 7, while peripheral (basal) cells expressed keratins 5/6, S100 protein, and p63. The apocrine gland-related antigen GCDFP-15 was focally expressed by tumor cells. The postoperative course was uneventful and at the 2-year follow-up no recurrence of the ceruminous adenoma was noted.
