Unilateral Idiopathic Calcinosis Cutis: A Case Report

Idiopathic Calcinosis Cutis in a Child: Report of a Rare Case

Calcinosis cutis is characterized by the deposition of calcium salts in the skin and subcutaneous tissue. Calcinosis cutis has different types, but the idiopathic type is considered the rarest type. We present the case of a 10-year-old boy who presented with a skin lesion on his right knee. No other similar nodules were noted elsewhere in the body. The lesion was first noted one year ago, and it slightly increased in size. The lesion was not pruritic and did not ulcerate. No history of previous trauma was provided. On physical examination, a nontender, firm, immobile, reddish, solitary nodule of 2 cm in diameter was observed on the extensor surface of the right knee. The patient underwent complete laboratory investigations that included hematological, biochemical, and immunological parameters, which yielded normal results. Excisional biopsy was performed, and histopathological examination revealed well-circumscribed deposits of basophilic materials in the subcutaneous tissue that is consistent with calcium deposits of calcinosis cutis. Idiopathic calcinosis cutis is a rare condition in children, particularly if it has a unilateral distribution. Proper evaluation should be performed to rule out any associated metabolic or systemic disorders that may alter the management pathway.

Iatrogenic calcinosis cutis in 9-month-old baby boy: a case report

Background

Calcinosis cutis is a rare condition, characterized by an accumulation of calcium salts in the skin and subcutaneous tissue. There are several types of this condition, including dystrophic, metastatic, idiopathic, calciphylaxis, and iatrogenic calcinosis cutis. The type related to our case is iatrogenic calcinosis cutis, and one its possible causes is calcium intravenous infusion. Physicians should be aware of this condition when giving calcium infusion.

Case presentation

Here we report the case of a 9-month-old Arabic - Saudi baby boy, who presented with abnormal movement for 1 day. Upon further investigation, his abnormal movement was found to be a manifestation of hypocalcemia and vitamin D deficiency. He was treated with intravenous calcium gluconate. Later, he had a treatment-related complication of intravenous calcium at the site of venipuncture causing swelling, which was initially soft but progressed to hard, over the left hand. Eventually, he was diagnosed with a case of iatrogenic calcinosis cutis due to intravenous calcium treatment.

Conclusion

There are multiple differential diagnoses of calcinosis cutis, as it resembles many other conditions. Careful history-taking, physical examination, and other investigations, such as radiological investigations, will aid in reaching a more accurate diagnosis and, thus, early treatment and intervention. Frequently checking the intravenous line and diluting the intravenous calcium may help reduce the occurrence of iatrogenic calcinosis cutis.

Dystrophic calcinosis cutis in chronic venous disease of the lower limbs

Abstract Lower limb ulcers secondary to chronic venous disease (CVD) are a significant public health problem in Brazil and account for about 70% of these ulcers. Despite recent technological advances and the various therapeutic options for treatment of these chronic injuries, several factors may be involved in resistance to treatment. Dystrophic calcinosis cutis (DCC) is a rare and often underdiagnosed condition that, when in conjunction with CVD, may be associated with a refractory healing process. In this article, we report a case of DCC in a patient with CVD and discuss its etiology, pathophysiology and possible treatment options.

Diffuse Idiopathic calcinosis cutis: a case report in a 13-year-old Syrian boy

Calcinosis cutis is characterized by the deposition of calcium salts in the skin and subcutaneous tissue. It is divided into the following subtypes: dystrophic, metastatic, iatrogenic, idiopathic and calciphylaxis. In this case, we report a 13-year-old Syrian boy with idiopathic calcinosis cutis, the lesions were unusually widespread, unlike the common condition which is usually localized to one area. The case was unrelated to any systemic or local disorders, and the patient had no complications, so no treatment was planned.

As the best of our knowledge, there are very few cases of diffuse or widespread idiopathic calcinosis cutis. We analyzed the clinical, laboratory, radiographical and pathological characteristics of our patient, which helped us to reach the final diagnosis. We will discuss the pathogenesis, investigation and management of this disease.
