Breast disorders in the pediatric and adolescent patient

Abstract:
Despite the wide range of breast abnormalities that affect patients in the pediatric and adolescent populations, some conclusions can be drawn. Breast self-examination in the adolescent population is controversial but is recommended for girls who carry the BRCA1 or BRCA2 gene beginning at age 18 to 21 years. All girls with a disorder of breast size or symmetry should be given the opportunity of consultation with a plastic surgeon to discuss reconstructive options. Ultrasound is the most appropriate initial investigation in any adolescent patient with a breast mass owing to the dense nature of breast tissue in this age group. Although it is extremely rare in this population, breast cancer must always be included in the differential diagnosis of a breast mass, particularly in the patient with a prior history of childhood malignancy or chest irradiation.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
