European Review for Medical and Pharmacological Sciences

|July 1, 1997

Summary

A rare case of a calcified osteo-producing fibroma, a benign retroperitoneal tumor, was diagnosed in a 31-year-old male. This slow-growing tumor, originating from the adrenal gland, presented with heavy calcifications, an unusual characteristic for fibromas.

Area of Science:

Oncology
Pathology

Background:

Retroperitoneal tumors are rare, with benign neoplasms accounting for approximately 25% of all cases.
Adrenal gland tumors can present as retroperitoneal masses, requiring accurate diagnostic imaging and histological evaluation.

Observation:

A 31-year-old male presented with a left para-aortic calcific mass identified via abdominal ultrasound.
CT scan revealed the mass originated from the left adrenal gland.
Surgical excision of the large, retroperitoneal mass, which was adherent but not infiltrating the left kidney and spleen, was performed.

Findings:

Histological examination diagnosed the tumor as a calcified osteo-producing fibroma.
The tumor exhibited heavy calcifications, an atypical feature for fibroma-type masses.
The patient's tumor demonstrated slow growth and a benign clinical course.

Implications:

This case highlights an unusual presentation of a benign retroperitoneal tumor with significant calcification.
Accurate diagnosis of retroperitoneal masses requires a combination of imaging and histopathology.
Understanding rare tumor variations is crucial for effective clinical management and treatment strategies.
