Background A malignant myoepithelioma is a rare tumor, mostly arising from the salivary glands. Myoepitheliomas of the ear have rarely been reported. The manuscript reports myoepithelial carcinoma of the external auditory canal (EAC) spreading to the infratemporal fossa. A clinician must be aware of anatomical variation of the bony EAC wall, such as the foramen of Huschke. This rare defect may be a pathway for spreading pathologies between these two anatomical regions. Case report We present a case of osteoma-like stenosis of the EAC, which turned out to be an extremely rare malignant tumor. The preoperative MRI and PET/CT revealed that two parts of the tumor communicated through a defect in the antero-inferior portion of the bony ear canal. No distant metastases were detected. Subsequently, the tumor was resected from the ear canal and the infratemporal fossa en bloc. Perioperatively the defect in the EAC wall was suspected of the foramen of Huschke. After the surgery, the older scans of the patient from the past showed no presence of a congenital EAC wall defect. Therefore, the authors concluded that the tumor aggressively grew through the bone due to its biological nature. Conclusion Malignant myoepithelioma of the external auditory canal is an extremely rare condition and could be misdiagnosed as other benign lesions. In cases of suspicious lesions, it is advisable to do a probatory biopsy from the EAC. Surgery is the treatment of choice in malignant myoepitheliomas, and regular follow-ups are essential to monitor for recurrence or metastatic disease. Any mass located at the antero-inferior portion of the EAC wall warrants close evaluation due to its potential for expansion from the EAC.

“…While primary ear cancer is uncommon, these structures are more frequently affected by cutaneous squamous cell carcinoma (cSCC) from the pinna or metastatic cSCC of the parotid gland [10]. Rare tumors such as myoepitheliomas, benign or malignant, may also affect the ear, including the external meatus [4][5][6]11].…”

Background: Myoepitheliomas are rare tumors, mostly arising from the salivary glands. Malignant myoepitheliomas of the ear have rarely been reported. This manuscript reports myoepithelial carcinoma of the external ear canal (EAC) spreading to the infratemporal fossa. A clinician must also be aware of anatomical variation of the bony EAC wall, such as the foramen of Huschke. This rare defect may be a pathway for spreading pathologies between these two anatomical regions. Case report: We present a case of osteoma-like stenosis of the EAC, which turned out to be an extremely rare malignant tumor. The preoperative MRI and PET/CT revealed that two parts of the tumor communicated through a defect in the antero-inferior portion of the bony ear canal. No distant metastases were detected. Subsequently, the tumor was resected from the ear canal and from the infratemporal fossa en bloc. Perioperatively the defect in the EAC wall was suspected of the foramen of Huschke. After the surgery, the older scans of the patient from the past showed no presence of a congenital EAC wall defect. Therefore, the authors concluded that the tumor aggressively grew through the bone due to its biological nature. This case report is aimed to improve the clinical knowledge of possible unusual communication between EAC and infratemporal fossa. Conclusion This is only the fourth reported case describing malignant myoepithelioma of the ear, to date. The purpose of this article is to point out the clinical importance of proper diagnostic management of ear canal masses, considering their location and possible invasion of adjacent structures. The manuscript also highlights the clinical importance and development of the foramen of Huschke.
