Phyllodes tumors are rare fibroepithelial neoplasms of the breast, classified as benign, borderline, or malignant based on histological features. Osseous metaplasia, characterized by presence bone formation within tumor, is an uncommon finding. This case report highlights rarity osseous metaplasia in a benign phyllodes tumor. A 23-year-old female presented with gradually enlarging lump left bre...

Osseous metaplasia is a rare disorder of endometrium in which a bone is formed from a different tissue inside the same individual. It is not generally applicable to the persistence of embryonic or foetal bone resulting in calcification or ossification. Most common presentation of osseous metaplasia of bone is infertility usually secondary. A case of osseous metaplasia as a cause of memetrorrhag...

Osseous metaplasia is a phenomenon which is described in a variety of tissue types with respect to both neoplastic and non-neoplastic conditions. In the gastrointestinal tract, osseous metaplasia (heterotopic bone formation) is rarely detected. Most of the reported cases were associated with malignant lesions. Here, we are reporting a rare case of a juvenile rectal polyp in a 14 years male, whi...

Results The 384 cases included 206 benign and 178 carcinomas in mixed tumors. Osseous metaplasia was present in 16.1% and calcified areas exclusively in 3.1% of lesions. Among all osseous metaplasia, 33.9% presented some type of extramedullary hematopoiesis, of which 71.4% were classified as myeloid metaplasia and 28.6% as extramedullary hematopoiesis. Myeloid metaplasia cases consisted of 67% ...

This paper presents a case of osseous metaplasia of the endometrium, a rarely encountered disease. Metaplasia is described as a change of one epithelium into another epithelium due to some triggering factor. In this case, endometrium is converted into osseous spicules. It might be followed by an abortion presenting with Infertility or chronic endometritis or metabolic disorder like hypervitamin...

Background: Osseous metaplasia occurring within the gastrointestinal tract is a rare phenomenon. Only a few of cases have been documented that osseous metaplasia can occur in colorectal polyps, although its underlying pathogenesis has not yet been elucidated. Methods: Two cases of osseous metaplasia within inflammatory and adenomatous polyps of colon, respectively. The clinical and histological...
