Lymphadenopathic form of solid variant of alveolar rhabdomyosarcoma: A rare case report.

Lymph node enlargement due to metastatic rhabdomyosarcoma, without an obvious primary tumor, is rare. We report a fine-needle aspiration diagnosed and histopathologically confirmed case of solid variant of alveolar rhabdomyosarcoma in a 13-year-old female. She presented with right cervical lymphadenopathy, followed by a diffuse swelling in right forearm 2 months later.

Ultrasound guided fine needle aspiration cytology in the diagnosis of retroperitoneal masses: A study of 85 cases.

Background: The diagnosis of retroperitoneal lesions is one of the most difficult areas in surgical pathology. The retroperitoneal space allows both primary and metastatic tumors to grow silently before the appearance of clinical signs and symptoms. Fine needle aspiration cytology has shown promising role in establishing the diagnosis in this region.
