Hyperplasia of the breast – "Hyperplastic" lesions of the breast include usual ductal hyperplasia, a focal expansion of the number of cells in a terminal breast duct, and atypical ductal hyperplasia, in which a more abnormal pattern of growth is seen, and which is associated with an increased risk of developing breast cancer.
Heck's disease, also known as Focal Epithelial Hyperplasia, is an asymptomatic, benign neoplastic condition characterized by multiple white to pinkish papules that occur diffusely in the oral cavity. [1] [2]: 411 It can present with slightly pale, smooth or roughened surface morphology. It is caused by the human papilloma virus types 13 and 32. [3]
Intravascular papillary endothelial hyperplasia (Masson's hemangio-endotheliome vegetant intravasculaire, Masson's lesion, Masson's pseudoangiosarcoma, Masson's tumor, papillary endothelial hyperplasia) Juvenile hyaline fibromatosis (fibromatosis hyalinica multiplex juvenilis, Murray–Puretic–Drescher syndrome)
Epidermodysplasia verruciformis (EV) is a skin condition characterised by warty skin lesions. [1] It results from an abnormal susceptibility to HPV infection (HPV). It is associated with a high lifetime risk of squamous cell carcinomas in skin. [1]
Because of the differences between mucous membranes and the skin (e.g., keratinizing mucosa does not have a stratum lucidum and non keratinizing mucosa does not have this layer or normally a stratum corneum or a stratum granulosum), sometimes specialized texts give slightly different definitions of hyperkeratosis in the context of mucosae.
Examining multiple deeper levels is recommended if initial cuts do not correlate well with the clinical history. [2] Psoriaform dermatitis typically displays: [2] Regular epidermal hyperplasia, elongation of the rete ridges, hyperkeratosis, and parakeratosis. Usually:A superficial perivascular inflammatory infiltrate
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.
epidermal necrosis; subcorneal pustules; confluent parakeratosis, epidermal hyperplasia, and marked papillary dermal hyperplasia in a psoriasiform pattern; angioplasia of papillary dermis; suppurative folliculitis; The vacuolated, pale, swollen epidermal cells and necrosis of the superficial epidermis are most characteristic.
