A Male Patient With Breast Hamartoma: An Uncommon Finding.

Mammary hamartoma is a rare type of breast tumor that is composed of the same elements as normal mammary tissue. This condition is very rare in men. In current literature, there are fewer than five case reports on male breast hamartoma. This benign pathology is under-reported because of several reasons. Since breast tumors are still considered an exclusively female diagnosis and statistically proven to be gynecomastia when arising in men, they are often overlooked. In addition to the uncommon clinical presentation in men, insufficiency of definitive pathologic and radiologic characteristics can make an accurate diagnosis a challenging task. Mammary hamartoma is a benign condition with an excellent prognosis. The following case describes a rare instance of an enlarging mammary hamartoma in a male patient, highlighting the imaging features, pathohistological findings, and clinical management.

Cat Scratch Disease Is an Entity Often Diagnosed in Breast Imaging Department During Axillary Lymph Node Assessment.

Cat scratch disease (CSD) is an infectious disease process of generally immunocompetent children and young adults. This infection can be introduced through skin trauma by direct exposure to the saliva of an infected kitten or cat. CSD is typically associated with constitutional symptoms and self-limited regional lymphadenopathy. In the sole presence of swollen lymph nodes, however, the differential diagnosis for CSD is relatively broad, including an active infection, an ongoing inflammatory process, and a metastatic process. CSD can present as axillary lymphadenopathy without typical constitutional symptoms. With proper clinical and laboratory investigation, CSD can be accurately identified and correctly diagnosed, as demonstrated in this case series featuring five symptomatic young adults with axillary lymphadenopathy. Breast imaging clinic specializes in lymph node assessment because metastatic lymphadenopathy is one of the most common presenting signs of breast cancer. Most isolated axillary lymphadenopathy without breast mass is benign reactive lymphadenopathy, but biopsy is necessary to exclude malignancies, such as metastatic lymphadenopathy or lymphoma.
