First Report on a Rare Poorly Differentiated Neuroendocrine Tumour of the External Auditory Canal Involving Pinna.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Malignancies arising from the external auditory canal are rare, with just 0.2% of all head and neck cancers. Only 4% of the external ear cancers arise from the external auditory canal. The most common histological variant is Squamous cell carcinoma, while neuroendocrine tumours are quite rare, with just 8 cases previously reported in EAC and few others in pinna. To the best of our knowledge, ours is the first reported case of poorly differentiated NET of EAC, which is involving pinna. The patient was a 56-year-old lady who presented with complains of right ear mass, blood-stained purulent discharge, decreased hearing and pain. Biopsy showed WHO grade III Neuroendocrine tumour. She was operated (lateral temporal bone resection with superficial parotidectomy and neck dissection with cervicofacial flap reconstruction). However, due to surgical site infection and flap failure, wound was again reconstructed with supraclavicular flap. She was planned for radiotherapy, but never turned for followup. The case represents the challenges in diagnosis, management and follow-up of such a rare entity.
