Abstract

Tumoral calcinosis has long been a disputed clinical-pathological subject. It has been characterized by the deposition of calcium salt and hydroxyapatite in different periarticular soft tissue regions. It is most commonly seen in adults, and rarely seen in children. In this report, we present the case of a six-year-old girl referred to our institution for one year with a history of left hip pain and swelling. The patient underwent an open reduction of left hip and acetabuloplasty for developmental dysplasia of the hip (DDH) at the age of two years. Systematic investigations were performed and showed that the patient had abnormal calcifications and large, ill-defined lesions with an irregular margin on the left hip extended to the left gluteal area with skin ulceration suggestive of primary tumor calcinosis. Medical therapy has started, and a follow-up appointment was given to her in a pediatric metabolic clinic. In addition, we present a brief literature review of the effect of medical and surgical treatments on tumor calcinosis.

Highlights

Tumoral calcinosis is considered a rare medical disorder characterized by the deposition of calcium salt and hydroxyapatite in different periarticular soft tissue regions [1]
The concept of tumoral calcinosis was described by Inclan et al [6] in his review which defined this condition as an abnormal calcification of soft tissue
The diagnosis of tumoral calcinosis is based on clinical evaluation, imaging modalities, and histopathologic examination

Summary

Introduction

Tumoral calcinosis is considered a rare medical disorder characterized by the deposition of calcium salt and hydroxyapatite in different periarticular soft tissue regions [1] It involved different regions such as hips, elbows, and shoulders, and they are the most commonly affected regions [2]. Radiographic pelvis X-ray was done for her, and it showed large abnormal calcifications on the left hip extended to the iliac bone (Figure 2A,B). CT for the chest, abdomen, and pelvis were performed to exclude any malignancy They showed a large calcified lesion (41 mm x 80 mm x 108 mm) seen in the inner border of the left iliac bone extended laterally to the left lower abdominal wall with infiltration of the lateral abdominal wall.
