Sir,

Calcinosis cutis (CC) is deposition of calcium salts in the skin. It is of four types i) dystrophic, ii) metastatic, iii) idiopathic and iv) iatrogenic [1]. Idiopathic CC is cutaneous calcification of unknown cause with normal serum calcium. Subepidermal calcified nodule and tumoral calcinosis are idiopathic forms of calcification [2].

Here authors present a case of idiopathic CC mimicking as xanthoma. A 45 year female presented with asymptomatic lesion on the right cheek for the past 8 months. There was no history of trauma or preexisting skin lesion. On examination, yellowish plaque with rough surface and irregular but well defined borders (Fig. 1). There were no similar lesions elsewhere on the body. Xanthoma and solar elastolysis were considered as differentials. Laboratory investigation revealed normal blood analysis including lipid profile. Skin biopsy was done and it was not suggestive of either xanthoma or solar elastolysis. Tissue was stained with Von Kossa for calcium salts (Fig. 2). Presence of calcium deposits was ascertained and provisional diagnosis of CC was made. Relevant investigations were carried out to know the cause of CC. Serum calcium, phosphate, and parathyroid hormone levels were normal. Based on the biochemical analysis and histopathology, idiopathic CC was made. Excision was done without recurrence (Fig. 3). Commonly, CC presents as chalky white plaque wherein diagnosis of CC is predictable [3]. Yellowish color of the lesion was misleading the scenario in this case. Hence, when asymptomatic yellowish plaque is encountered, CC should also be kept in differentials with xanthoma. This case is reported because of yellowish color which was mimicking xanthoma.

Consent

The examination of the patient was conducted according to the Declaration of Helsinki principles.
