TLDR Hair loss can be a key sign of a rare type of rickets when vitamin D treatment doesn't work and advanced tests aren't available.
The document reports on a case of Vitamin D-dependent rickets Type II, an uncommon autosomal recessive disorder, and highlights the association of alopecia with the disease. The case involves a child diagnosed with this condition, and the report emphasizes that alopecia, either of the scalp or body, can be a significant indicator for this syndrome, especially when rickets is resistant to treatment and there is a lack of facilities to measure 1,25-dihydroxyvitamin D (1,25(OH)2 D) and parathyroid hormone levels. The document suggests that in the absence of advanced diagnostic capabilities, the presence of alopecia may serve as an important diagnostic clue for this rare form of rickets.
