Objectives:
Atypical lymphatic spread of germ cell tumors to inguinal lymph nodes has been reported mostly related to prior surgical involvement of the inguinoscrotal region, as in orchiopexy.
Methods:
A patient with cryptorchidism and failed orchiopexy in his childhood was diagnosed with a testicular neoplasm. Inguinal orchiectomy was performed.
Results:
Pathological analysis showed classical seminoma spreading into a subcutaneous adjacent lymph node. Further metastatic disease was not found. Patient was treated with adjuvant chemotherapy.
Conclusions:
We emphasize the need for accurate staging and a multidisciplinary approach when dealing with onco-urological patients presenting with atypical disease.

The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
