Abstract

A histologically confirmed malignant, primary bone tumour in the pelvis, presumably an osteosarcoma, underwent spontaneous regression. The large tumour was inoperable and gave rise to severe pain as well as difficulty in walking. After 2 years of progression, with increasing desition improved spontaneously, and at present the patient is alive, almost symptom-free, after 6 years follow-up.

Case Details

Disease Location

Pelvis

Personal Characteristics

36-year-old male

Clinical Characteristics

Radiography disclosed widespread osteolytic lesion in left half of pelvis open biopsy at anterior demarcation of tumor in iliac bone exploratory operation through wide posterior approach tumor in iliac bone measuring 12x8x8 cm histological examination of tumor tissue displayed tumor was inoperable condition deteriorated steadily--> radiologic examination displayed destruction of left half of pelvis

Remission Characteristics

In course of latter half of 1973, reveral occurred pain subsided, normal walking resumed, tumor area increasingly delimited & sclerosed

Treatment & Mechanisms

Proposed Remission Mechanisms

Possible causes: hypersensitivity reaction hemorrhage in tumor reaction to tumor protein immunological factors

Clinical Treatment

Symptomatic treatment (non-weight-bearing & analgesic medication)
