Recuperation of severe tumoral calcinosis in a dialysis patient: A case report

Table 1 Patient’s calcium, phosphate, parathormone and 25-OH vitamin D2/D3 levels: timeline according to the initial diagnosis of tumoral calcinosis

Serum parameter (unit)	28 mo before ID (start of RRT)	10 mo before ID (on PD)	At admission ID (on PD)	3 mo post ID (on HD)	4 mo post ID (on HD)	22 mo post ID (on HD)	34 mo post ID (on HD)	Reference range
Calcium (mmol/L)	2.47	2.51a	2.75a	3.24	2.82	2.14	2.19	2.15-2.5
Phosphate (mmol/L)	2.00	2.0	2.3	1.8	1.7	1.31	1.21	0.81-1.45
Ca x P product (mmol2/L2)	4.94	5.10	6.33	5.83	4.79	2.80	2.65	b
Parathormone (pg/mL)	185	N/A	N/A	104	285	620	N/A	15-65
25-OH vitamin D2/D3 (ng/mL)	53.0	N/A	N/A	29.4	28.7	34.2	N/A	20-70

^aSerum calcium levels were corrected by albumin concentration;

^bNKF – K/DOQI guidelines recommend a Ca x P product target less than 4.5 mmol²/L²[6]. Ca: Calcium; HD: Hemodialysis; ID: Initial diagnosis; N/A: Not available; P: Phosphate; PD: Peritoneal dialysis; RRT: Renal replacement therapy.
