Synonyms for in situ: * Confined to epithelium * Ductal carcinoma in situ (DCIS) * Intracystic * Intraductal * Intraepidermal * Intraepithelial * Lobular carcinoma in situ (LCIS) * Lobular neoplasia * Lobular noninfiltrating * Noninfiltrating * Noninvasive * No stromal involvement * Papillary intraductal * Papillary non infiltratingNotes
**Note 1:** **Dimpling, tethering** * Changes such as dimpling of the skin, tethering, and nipple retraction are caused by tension on Cooper's ligament(s), not by actual skin involvement. * They do not alter the classification. **Note 2:** **Clinical evidence ONLY descriptions** * Adherence, attachment, fixation, induration, and thickening are clinical evidence of extension to skin or subcutaneous tissue; assign code 200 if that is the only information available. * Do not use these descriptions for pathological assessment of the breast. **Note 3:** **Fixation, NOS** * **"Fixation", NOS** is involvement of pectoralis muscle; assign code 200. **Note 4:** **Inflammatory carcinoma** * Inflammatory carcinoma is a clinical diagnosis. It is defined as greater than 33% of a breast involved WITH erythema, edema, peau d'orange, or other terms describing skin changes. * See codes **400 and 500** for descriptions of inflammation **WITHOUT** a diagnosis of inflammatory carcinoma. * See code **600** for a diagnosis of inflammatory carcinomaDefault
