ABSTRACT
Extranodal marginal zone lymphoma (EMZL) is a low-grade subtype of B-cell non-Hodgkin lymphoma that can affect any mucosal tissue, most commonly the GI tract. Primary involvement of the breast, known as primary breast lymphoma (PBL), is a very rare manifestation. We report an unusual case of a 65-year-old woman with primary breast EMZL presenting as calcifications discovered during screening mammography. This represents an exceedingly atypical appearance of primary breast lymphoma that is rarely described in the literature.
ABSTRACT
Marginal zone lymphoma of mucosa-associated lymphoid tissue is a B-cell lymphoma which arises in extranodal sites, most commonly the stomach. Involvement of the breast is very rare. We present a case of an asymptomatic 63-year-old woman with synchronous mucosa-associated lymphoid tissue lymphoma involving both breasts and subcutaneous tissues. This represents a form of secondary breast lymphoma (given the concurrent involvement of the breast and non-mammary organ systems) and is an exceedingly rare diagnosis which, to our knowledge, has only been discussed in a few case series.
ABSTRACT
Endosalpingiosis is defined as the ectopic location of benign ciliated tubal epithelium outside of the fallopian tubes. It is a rare entity that was previously regarded as an incidental finding on pathology, and is becoming more prevalent within the medical literature. Diagnosis is made based on histologic sampling. There are no specific radiological features but commonly reported findings include numerous cystic and solid masses scattered throughout the pelvis. Common ectopic locations seen on imaging include the serosa of the uterus, fallopian tubes, ovaries and the pelvic cul-de-sac. Less common locations include the bladder wall, omentum, bowel serosa, and skin. We present the clinical presentation of a patient with histologically proven endosalpingiosis. Atypical imaging findings and correlative histology are also reviewed.
