Nephrogenic Metaplasia of the Ureter
American Journal of Clinical Pathology, 1983We present what, to our knowledge, is the first reported case of nephrogenic metaplasia of the ureter. Nephrogenic metaplasia involves the transitional epithelium of the urinary tract and results in the formation of epithelial tubules, which are histologically similar to renal tubules.

Synovial Metaplasia of the Skin
The American Journal of Surgical Pathology, 1987Synovial metaplasia has been described in bone or soft tissues following surgical procedures or under experimental conditions. Three cases in which skin biopsies showed synovial metaplasia of the dermis are herein reported. The metaplastic foci were associated with cyst formation and transepidermal fistulae.

Synovial metaplasia of the skin
Virchows Archiv A Pathological Anatomy and Histopathology, 1993We present two female patients, aged 15 and 45 years, with synovial metaplasia of the skin. Both lesions, localized in the knee and hand respectively, arose after preceding local trauma. Case 1 had intradermal irregular cystic spaces in the adjacent myxoid stroma of which large polygonal eosinophilic cells were found.

Are metaplasias in colorectal adenomas truly metaplasias?
The American journal of pathology, 1984Five thousand seven hundred seventy-eight adenomas or adenomas containing carcinoma from 3215 patients were examined by routine histologic methods for the presence of epithelial metaplasias. Three forms of epithelial metaplasia were encountered: squamous cell metaplasia (0.44%), Paneth cell metaplasia (0.20%), and melanocytic metaplasia (0.017%).

Thymoma with Osseous Metaplasia
Journal of Computer Assisted Tomography, 2001A 69-year-old woman with a 15-year history of abnormal chest shadow was referred to our hospital. An enhanced chest CT scan of the anterior mediastinum revealed a mass containing a high-density area. The preoperative radiologic diagnosis was thymoma. Operation was performed in October 2000.

Oncocytic metaplasia of the pharynx
Otolaryngology–Head and Neck Surgery, 1991Oncocytic metaplasia of the pharynx has been infrequently described, with only two previous cases in the literature. With the advent of panendoscopy during the last decade, however, a better understanding of this histopathologic diagnosis is desirable. Thirty‐three cases are reviewed, with thirty occurring in the nasopharynx.

A Gnogenic myeloid metaplasia may best be defined as a disorder involving hematopoiesis outside the usual marrow sites, most frequently accompanied by fibrosis of the marrow. This condition represents a distinct clinical-hematologic-roentgenologic entity, with characteristic features. The literature dealing with this disease is voluminous and confused.

We present a unique case of a lipoma with widespread synovial metaplasia. A 52-year-old woman had a recurrence 1 year after excision of a subcutaneous lipoma of the neck. Histologically, the primary tumor was an ordinary lipoma. The recurrent tumor was a myxoid lipoma with synovial metaplasia.

Postpolycythemia Myeloid Metaplasia
Archives of Internal Medicine, 1974From 1950 through 1955, a total of 207 patients were seen at the Mayo Clinic with a diagnosis of polycythemia vera; 29 developed postpolycythemia myeloid metaplasia (PPMM). The patients with PPMM tended to have more symptoms than patients with agnogenic myeloid metaplasia.
