Primary adrenal leiomyosarcoma with lymph node metastasis: a case report.

BACKGROUND

Leiomyosarcomas typically originate in smooth muscle cell. Leiomyosarcoma potentially arising from the adrenal gland is an extremely rare mesenchymal tumors associated with delayed diagnosis and poor prognosis.

CASE PRESENTATION: A 34-year-old man visited our department complaining of right hypochondriac pain. Computed tomography demonstrated a solid mass measuring 5.2 cm in diameter above the right kidney, corresponding to the right adrenal gland, and a lymph node mass, which appeared to have invaded the IVC wall. Right adrenalectomy and lymphadenectomy were performed. A microscopic examination revealed primary adrenal leiomyosarcoma with lymph node metastasis. No adjuvant therapy was performed, and the patient remains recurrence-free at 10 months postoperatively.

CONCLUSIONS

We experienced a very rare case of primary adrenal leiomyosarcoma. Aggressive surgical resection including vascular reconstruction may be associated with improved survival.
