Summary
Leydig cell tumors in adults can cause endocrine issues like gynecomastia before a mass is felt. Treatment varies, with surgery for adults and steroid suppression for congenital adrenogenital syndrome.
Area of Science:
- Endocrinology
- Urologic Oncology
Background:
- Leydig cell tumors (LCTs) are the most common non-germ cell testicular tumors in adults.
- Endocrinologic manifestations can precede palpable testicular masses in LCT patients.
Observation:
- This study discusses four patients with LCTs and endocrine symptoms.
- Three adult patients presented with gynecomastia, a common sign of increased estrogen secretion.
- One patient had congenital adrenogenital syndrome with testicular enlargement, complicating diagnosis.
Findings:
- Endocrine signs occur in 30% of adult LCT cases.
- Distinguishing LCT from adrenal rest hypertrophy in adrenogenital syndrome is challenging.
- Gynecomastia is the most frequent endocrine manifestation, linked to estrogen production.
Implications:
- Early recognition of endocrine signs is crucial for timely LCT diagnosis.
- Treatment strategies differ: inguinal orchiectomy for adult LCTs.
- High-dose steroid suppression is the initial approach for adrenogenital syndrome before surgical intervention.
