摘要:

Cornoid lamellation is a constant histologic marker of porokeratosis in its many variants. This histologic appearance, heretofore thought to be pathognomonic of and restricted to porokeratosis alone, has also been found by us in a variety of other conditions. Cornoid lamellation is, therfore, analogous to the histologic findings of focal acantholytic dyskeratosis, epidermolytic hyperkeratosis, and follicular mucinosis as a distinctive histologic reaction pattern that reflects disordered progression of epidermal cells to cornification.

摘要:

A brief historical review and a unifying classification of the non-Hodgkin's lymphomas are presented. The principles underlying this classification are that 1) ncoplastic cells are named after normal cells they resemble most; 2) the germinal center is a reaction center where small lymphocytes undergo blastic transformation as well as the birthplace of small lymphocytes; and 3) lymphoid cells can be subdivided by size and cytologic characteristics into small, intermediate, and large types. This classification can be expanded by additional qualifying terms. Whether such expansions are justified in terms of reproducibility and clinical significance remains to be proven.

摘要:

A historical basis is proposed for the 13th-century legend of the Pied Piper, who led away the rats from the town of Hamelin and, when refused payment for his services, led away 130 children and disappeared with them in the mountains. It is suggested that the children actually died in an outbreak of disease and were buried in a common grave at the site of the legendary disappearance. The association with rats points to a rodent-borne infection, and the pied (mottled) coat of the Piper seems to indicate a disease causing conspicuous macular lesions. Historical and epidemiologic arguments are presented in favor of murine typhus as the predominant infection in the Hamelin epidemic.
