# Idiopathic tumoral calcinosis of the left thigh: a case report

## TL;DR

A rare case of idiopathic tumoral calcinosis in a Sudanese woman is reported, emphasizing the importance of recognizing this condition in underreported regions.

## Contribution

This is the first documented case of idiopathic tumoral calcinosis in Sudan.

## Key findings

- The patient had a painless, calcified mass in her left thigh confirmed by imaging and histopathology.
- Surgical excision was successful with no malignancy detected.
- The case underscores the need to include this condition in the differential diagnosis of soft tissue masses.

## Abstract

Idiopathic tumoral calcinosis is a very rare benign condition characterized by pathological deposition of calcium phosphate crystals into the soft tissues, particularly into the peri-articular regions. This case report narrates the first reported case of idiopathic tumoral calcinosis in Sudan. A 38-year-old Sudanese female from Gadarif presented with a history of progressive enlargement of the left thigh swelling over a period of 1 year, which was painless. Clinical examination revealed a firm and well-circumscribed mass without overlying skin changes. Imaging revealed calcification with a characteristic “chicken wire” pattern in X-rays, and histopathology confirmed lobulated calcium deposits surrounded by fibrous tissue and foreign body giant cell reactions without malignancy. The patient underwent complete surgical excision of the mass under spinal anesthesia, and her recovery was uneventful. This case highlights the need for recognition of idiopathic tumoral calcinosis in the differential diagnosis of soft tissue masses, especially in the region where these are underreported.
