Described in Peter Parker's notebook, case No. 3,790, June 19th 1837: 'Yang She, aged 20, of Huayuen, had a tumour pendulous from the chin and larynx. It commenced ten years since, and the last six years had been very cumbersome. The attachment beneath the chin was five inches in circumference. Centrally and horizontally it measured two feet three inches, and vertically three feet two inches. It extended below the umbilicus, but not so as to rest in the lap; consequently, its weight was sustained by its attachment, and the patient had to sit constantly in a bracing posture, to prevent its drawing down her head. The normal features were distorted, the cheeks drawn tense by the weight of the tumour.’
