Fibroadenomas are benign breast tumours characterized by an admixture of stromal and epithelial tissue. Breasts are made of lobules (milk producing glands) and ducts (tubes that carry the milk to the nipple ).
HCCC consist of cells with abundant clear cytoplasm, arranged in cords, trabeculae or clusters in a hyalinized stroma. [3] Nuclear pleomorphism is usually minimal and mitoses are infrequently seen. [2] Owing to their glycogen content, which explains the "clear" appearance under the microscope, tumour cells stain with PAS.
It consists of a zone of hyalinized collagen between dead cells and preserved cells, commonly eosinophilic. If dead nuclei present, they are uniform and the chromatin is often. Necrosis secondary to ulceration in submucous leiomyomas features acute inflammatory cells and a peripheral reparative process, whereas ghost outlines of nuclei are ...
This condition is characterised by abnormal growth of hyalinized fibrous tissue with cutaneous, mucosal, osteoarticular and systemic involvement. Clinical features include extreme pain at minimal handling in a newborn, gingival hypertrophy, subcutaneous nodules, painful joint stiffness and contractures, muscle weakness and hypotonia.
Micrograph showing the characteristic hyalinized papillary cores found in some hereditary leiomyomatosis and renal cell carcinoma syndrome-associated renal cell carcinomas. H&E stain . Hereditary leiomyomatosis and renal cell carcinoma ( HLRCC ) or Reed's syndrome is rare autosomal dominant disorder associated with benign smooth muscle tumors ...
For comparison, this is about 15 years older than the typical age of patients with a fibroadenoma, a common differential diagnosis in patients with a suspected phyllodes tumors. [26] Younger women have a higher chance of having a benign phyllodes tumor, while older women are more likely to have higher-grade tumors.
Usual ductal hyperplasia with small cells that lack atypia. Histopathology of usual ductal hyperplasia (UDH) on H&E stain and immunohistochemistry.As seen on higher magnification H&E stain at left, it has the usual irregular "slit-like" lumina.
A true mixed tumor contains multiple types of neoplastic cells. [4] Some sources require the included tissue types to be neoplastic for the definition of mixed tumor. [1]A "false" mixed tumor contains one type of neoplastic cells, but which have more than one appearance.
