Pagetoid : ウィキペディア英語版
Pagetoid
Pagetoid is a term used in dermatology to refer to "upward spreading" of melanocytes into the epidermis. It is uncommon and a possible indication of a precancerous or cancerous condition. Cells display pagetoid growth when they invade the upper epidermis from below. Squamous cell carcinoma, melanoma in situ, Pagetoid Bowen disease and other carcinomas can all display pagetoid growth.
The term Pagetoid (Paget-like) is derived from the Extramammary Paget's disease, wherein the large tumour cells are arranged singly or in small clusters within the epidermis and its appendages. These cells are distinguished by a clear halo from the surrounding epithelial cells and a finely granular cytoplasm.〔Kumar V, Abbas AK, Fausto N. Robbins and Cotran's Pathologic Basis of Disease.Elsevier.1069〕 This proliferation of cells in the epidermis is responsible for the 'buckshot scatter' pattern.〔http://www.dermnetnz.org/pathology/pathology-glossary.html〕 This is a typical feature of superficial spreading type of Malignant Melanoma.
