When this produced no results, the alliance members took their campaign to Tokyo, securing an official visit to Minamata by members of the Japanese Diet. During the visit on 2 November, alliance members forced their way into the factory and rioted, causing many injuries and ¥10 million ($100,000) worth of damage. The violence was covered widely in the media, bringing the nations attention to the Minamata issue for the first time since the outbreak began. Another mediation committee was set up, and an agreement was hammered out and signed on 17 December. Some ¥25 million of "sympathy money" was paid to the alliance and a ¥65 million fishing recovery fund was established. In 1959, the people with  Minamata disease were in a much weaker position than the fishermen. The recently formed Minamata Disease Patients Families Mutual Aid Society was much more divided than the fishing cooperatives. Patients families were the victims of discrimination and ostracism from the local community. Local people felt that the company (and their city that depended upon it) was facing economic ruin. To some patients, this ostracism by the community represented a greater fear than the disease itself. After beginning a sit-in at the Chisso factory gates in November 1959, the patients asked Kumamoto Prefecture Governor Hirosaku Teramoto to include the patients request for compensation with the mediation that was ongoing with the prefectural fishing alliance. Chisso agreed and after a few weeks further negotiation, another "sympathy money" agreement was signed.
A trichilemmal cyst  is a common cyst that forms from a hair follicle, most often on the scalp, and is smooth, mobile, and filled with keratin, a protein component found in hair, nails, skin, and horns. Trichilemmal cysts are clinically and histologically distinct from trichilemmal horns, hard tissue that is much rarer and not limited to the scalp. Rarely, these cysts may grow more extensively and form rapidly multiplying trichilemmal tumors, also called proliferating trichilemmal cysts, which are benign, but may grow aggressively at the cyst site. Very rarely, trichilemmal cysts can become cancerous. Classification
Trichilemmal cysts may be classified as sebaceous cysts, although technically speaking are not sebaceous. "True" sebaceous cysts,  which originate from sebaceous glands and which contain sebum, are relatively rare and are known as steatocystoma simplex or, if multiple, as steatocystoma multiplex. Medical professionals have suggested that the term "sebaceous cyst" be avoided since it can be misleading. : 31  In practice, however, the term is still often used for epidermoid and pilar cysts. Pathogenesis
Trichilemmal cysts are derived from the outer root sheath of the hair follicle. Their origin is currently unknown, but they may be produced by budding from the external root sheath as a genetically determined structural aberration. They arise preferentially in areas of high hair follicle concentrations, so 90% of cases occur on the scalp. They are solitary in 30% and multiple in 70% of cases.Histologically, they are lined by stratified squamous epithelium that lacks a granular cell layer and are filled with compact "wet" keratin.
