mammary peri-prothetic capsula
Formation of a fibrous envelope around the implant, a so-called capsule with resultant contracture of the prosthesis, is an occasional complication of augmentation mammoplasty.
The capsulectomy specimen contains mature scar tissue with mononuclear cells, histiocytes, and foreign body giant cells.
Studies showed a striking form of papillary villous synovial-like hyperplasia similar to detritic synovitis, a form of proliferative synovitis caused by orthopedic (...)

pediatric non-Helicobacter pylori atrophic gastritis
Although autoimmune atrophic gastritis is classically a disease of elderly adults, recent studies have described the disease in younger adults, particularly in those with other autoimmune diseases and iron-deficiency anemia. Atrophic gastritis in pediatrics is a rare and possibly underdiagnosed entity.

Papillary adenocarcinoma is another common histologic variant often seen in early gastric carcinoma. It tends to affect older people, occur in the proximal stomach, and is frequently associated with liver metastasis and a higher rate of lymph node involvement. Histologically, it is characterized by epithelial projections scaffolded by a central fibrovascular core.
micropapillary carcinoma of stomach
Micropapillary carcinoma of stomach is a newly recognized histologic variant characterized by small papillary clusters of tumor cells without a distinct fibrovascular core.
The micropapillary features are often noted in the deep advancing edge of tumor, surrounded by an empty space mimicking retraction artifact.
Micropapillary carcinoma of stomach, as its counterpart at other organs, tends to form endolymphatic tumor emboli and metastasize to lymph (...)
Mucin production in primary liver neoplasms is typically interpreted as evidence for biliary differentiation. However, it has been observed benign and malignant liver tumors that have abundant extracellular myxoid/mucinous material, yet have only evidence of hepatocellular differentiation.
Extracellular myxoid/mucinous material in isolation should not be interpreted as cholangiocarcinoma. Furthermore, the unique morphology, the clinical characteristics, and the immunophenotype results (...)
