Papillary microcarcinoma is a subset of papillary thyroid cancer defined as measuring less than or equal to 1 cm. [15] The highest incidence of papillary thyroid microcarcinoma in an autopsy series was reported by Harach et al. in 1985, who found 36 of 101 consecutive autopsies to have an incidental microcarcinoma. [16]
Inflammatory papillary hyperplasia (IPH) is a benign lesion of the oral mucosa which is characterized by the growth of one or more nodular lesions, measuring about 2mm or less. [ 4 ] [ 5 ] The lesion almost exclusively involves the hard palate, and in rare instances, it also has been seen on the mandible.
A papillary tumor is a tumor shaped like a small mushroom, with its stem attached to the epithelial layer (inner lining) of an organ. [ 1 ] [ 2 ] It consists of papillae , which are outgrowths that consist of stroma with at least one central blood vessel, surrounded by epithelium.
Papillary microcarcinoma is a subset of papillary thyroid cancer defined as a nodule measuring less than or equal to 1 cm. [41] 43% of all thyroid cancers and 50% of new cases of papillary thyroid carcinoma are papillary microcarcinoma.
Papillary renal cell carcinoma (PRCC) is a malignant, heterogeneous tumor originating from renal tubular epithelial cells of the kidney, which comprises approximately 10-15% of all kidney neoplasms. [1] Based on its morphological features, PRCC can be classified into two main subtypes, which are type 1 and type 2 (eosinophilic). [2]
Papillary muscle rupture can be caused by a myocardial infarction, and dysfunction can be caused by ischemia. Rarely, blunt chest trauma can be the cause of papillary muscle rupture, resulting from the sudden deceleration or compression of the heart. [4] Complications may lead to worsening of mitral regurgitation. [5]
Thyroid neoplasm is a neoplasm or tumor of the thyroid.It can be a benign tumor such as thyroid adenoma, [1] or it can be a malignant neoplasm (thyroid cancer), such as papillary, follicular, medullary or anaplastic thyroid cancer. [2]
Papillary tumors of the pineal region were first described by A. Jouvet et al. in 2003 [1] and were introduced in the World Health Organization (WHO) classification of central nervous system in 2007. [2] Papillary Tumors of the Pineal Region are located on the pineal gland which is located in the center of the
