It is essential to recognize the ana- tomic continuity of subserous connective tissue with its vessels and lymphatics as an extension of the Early Embryonic Development extraperitoneal space that underlies the holistic con- cept of the subperitoneal space.

Clinical Embryology of the Abdomen Thus, by the 4th week the continuity of the body wall (extraperitoneal space) with the sus- pended gastrointestinal tract is established by the connecting primitive mesentery. This interconnec- tion persists throughout development and into the adult form as the subperitoneal space.

Although melanoma has been described in patients with Becker’s nevus, the risk of malignant transformation appears to be very low. Traditional surgical approaches to remove Becker’s nevus are either unsuccessful or result in signifcant scarring. Laser technol- ogy offers the clinician a means to reduce both the pigmentation and the hypertrichosis often seen in Becker’s nevus, and there- fore may improve the cosmetic appearance of the lesion. Man- agement of asymptomatic, benign lesions should be based on confrming the diagnosis and fully documenting any associated pathology.

Differential Diagnosis The differential diagnosis includes cancer, fibroade- noma, lobular hyperplasia, lipoma, and (rarely) leukemia, lymphoma, sarcoma, neuroma, and tu- berculosis. Because the mass has persisted longer than 2 weeks, it requires further evaluation by completion of a modified triple test (addition of a needle biopsy to the clinical breast ex- amination and ultrasound).
