A case of otoliquorrhoea secondary to immunotherapy response in head and neck cutaneous squamous cell carcinoma. When abrupt response may worry the physician
Extension of cutaneous squamous cell carcinoma (cSCC) to the temporal bone represents a challenging scenario associated with poor outcomes. Scarce literature data is available to guide clinicians towards the optimal management of this disease. A dedicated TNM staging is lacking, and the modified Pittsburgh classification is typically adopted. Up to 80% of cSCC arises in the head and neck (HN) area, and the ear is part of the so called “H-zone”, an area at highrisk for tumour. Invasion of temporal bone is a condition to be considered in auricular cSCC, representing the consequence of a direct invasion of mastoid cortex or through external auditory canal (EAC) and middle ear.
