ABSTRACT
Primary small cell neuroendocrine carcinoma (SCNC) of the larynx is a rare subtype of laryngeal cancer, accounting for less than 1% of all laryngeal tumours. It most commonly affects smokers in their fifth to sixth decade of life and is characterised by a high incidence of advanced disease at presentation and an aggressive clinical course. Here we present a case of SCNC of the larynx, presenting initially with dysphonia, and an associated literature review collating current knowledge regarding therapeutic approaches. After review of 260 cases in the literature we determined a disease-specific survival of 33.1%. Combined chemoradiotherapy is currently the recommended first-line treatment option.

Pulmonary enteric adenocarcinoma (PEAC) is a rare, aggressive variant of lung adenocarcinoma with early metastatic potential. We present the case of a male smoker in his 50s who presented with right-sided numbness, pain and headache. Imaging revealed a destructive skull base mass invading the right sphenoid sinus. Histopathology was consistent with PEAC. The diagnosis was metastatic PEAC with a distant spread to the skull and represents the first case reported in the literature. We present an associated literature review of the clinical presentation, histological features and management of PEAC with skull metastasis. Metastasis should be considered when evaluating any persistent cranial lesion. Diagnosis requires thorough clinical, radiological and pathological assessment. Treatment involves surgical resection, chemoradiation and targeted therapy. Prognosis directly correlates with clinical stage at presentation. This case highlights the importance of careful evaluation of skull lesions, even in patients without known primary malignancy. Early diagnosis and multimodal therapy may improve outcomes.
