What is the best course of action for a 46-year-old male patient with minimal benign gynecomastia (enlargement of breast tissue in males) and no suspicious findings?

From the Guidelines

For a 46-year-old male with minimal benign gynecomastia and no suspicious findings, the best course of action is typically reassurance and monitoring without specific medical intervention. The patient should be informed that his condition is benign and common, affecting up to 30% of men. Regular follow-up examinations every 6-12 months are recommended to monitor for any changes. If the gynecomastia causes significant psychological distress or physical discomfort, treatment options could be considered. These include medications such as tamoxifen (10-20 mg daily for 3-6 months) or surgical options like liposuction or mastectomy for persistent cases. However, these interventions are usually unnecessary for minimal gynecomastia. It's essential to identify and address any potential underlying causes, such as certain medications (spironolactone, finasteride, some antipsychotics), recreational drugs, or hormonal disorders, as suggested by the evaluation and management of testosterone deficiency guideline 1. Weight management through diet and exercise may help reduce the appearance of gynecomastia if there is an adipose tissue component. The patient should be advised to report any changes in the breast tissue, particularly rapid growth, pain, discharge, or lumps, which would warrant immediate reevaluation, as recommended by the ACR Appropriateness Criteria for the evaluation of the symptomatic male breast 1. In this case, since the patient's physical examination is consistent with gynecomastia and there are no suspicious findings, no further imaging is routinely recommended, according to the ACR Appropriateness Criteria 1. The patient's laboratory tests, including CHEM 24, HDL, CBC, T3, T4, TSH, and testosterone, may help identify any underlying hormonal imbalances that could be contributing to the gynecomastia, as suggested by the evaluation and management of testosterone deficiency guideline 1. Overall, a conservative approach with monitoring and lifestyle modifications is the most appropriate course of action for this patient.

From the Research

Diagnosis and Findings

• The patient has been diagnosed with minimal benign gynecomastia bilaterally, which refers to the enlargement of breast tissue in males 2.
• The breast tissue is almost entirely fatty, categorized as Category A 3.
• No suspicious mass, suspicious calcifications, or unexpected architectural distortion was found in either breast.

Treatment and Management

• For patients with persistent gynecomastia, a tailored approach of close follow-up and use of anti-estrogen drugs may be recommended 3.
• Tamoxifen, a selective estrogen receptor modulator (SERM), has been found to be a safe and effective alternative treatment for male pubertal gynecomastia 4.
• Discontinuing the use of contributing medications and treating underlying diseases are the mainstay of treatment for nonphysiologic gynecomastia 5.
• Medical therapy can be tried for patients with persistent gynecomastia associated with tenderness or social embarrassment prior to contemplating surgical removal of the breast tissue 6.

Recommendations

• Clinical follow-up is recommended for the patient 3.
• The patient's laboratory tests, including CHEM 24, HDL, CBC, T3, T4, TSH, and testosterone, should be evaluated to determine if there are any underlying conditions contributing to the gynecomastia 2.
• Treatment should be pursued early and directed by the patient's needs and preferences 5.
