Adriano, Hannah Kathlyn P. 1R-MT1st Shift Journal in MT 632″Is there any link between tumor-induced osteomalacia and psoriasis? A case report”Mojtaba Akbari1, Bagher Larijani2, Sasan Sharghi3, Ali Jalili2 and Sayed Mahmoud Sajjadi-Jazi2*Journal of Diabetes & Metabolic Disorders (2017) 16:34 DOI 10.1186/s40200-017-0315-5Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome in which patients experience bone pain, fractures, and muscle weakness. The cause is high blood levels of the recently identified phosphate and vitamin D-regulating hormone, fibroblast growth factor 23 (FGF23).

 Fibroblast growth factor-23 is a bone-derived phosphaturic hormone that works increase phosphate excretion and helps metabolize vitamin D. Psoriasis is a common, genetic, and inflammatory diseases that speeds up the life cycle of skin cells. It causes cells to build up rapidly on the surface of the skin which form scales and red patches that are itchy and even painful. This case report was the second case of tumor-induced osteomalacia accompanied by psoriasis. The study involved a young patient who has a psoriasis and as it progressed, he also suffered from bone pain and muscle weakness. Thus, the goal of the study was to further discover the link between the mentioned diseases through extensive research as well as to identify and discuss the role of Fibroblast growth factor-23 in regulating immune function and its connection to the pathogenesis of psoriasis.The patient has been receiving treatments for plaque-type psoriasis since he was a child.

Then, years after, he began to feel muscle weakness, bone pain, and generalized psoriatic skin lesions. Various tests including magnetic resonance imaging (MRI) were conducted and it showed skeletal demineralization. It was also revealed that he has hypophosphatemia (extremely low phosphate level) and phosphaturia (urine excretion of excessive amounts of phosphate). With this, he was advised to change the dosage of his medication to further analyze its effect on his skin and bone. However, his symptoms got worsened despite the given treatment; he could barely walk and eventually became bedridden. Furthermore, there has been a significant 20-cm loss in his height, a decrease in both upper and lower limbs muscle force and skin hyperpigmentation. Multiple results also showed changes in his joints without any evidence of inflammatory arthritis.

Finally, his physicians have discovered that the patient have a FGF-23-related hypophosphatemia particularly TIO. The tumor was then localized and was completely resected which led to the remineralization of the bone. His phosphate supplementation was discontinued and his follow up check-ups showed that muscle weakness and bone pain had gradually improved.

A published article by Okan et al. demonstrated that the FGF-23 level is high in psoriasis patients and is associated with psoriasis severity. Overall, it was found out that TIO may alter the clinical course of psoriasis by secreting a high amount of FGF-23 causing an increased risk of malignancy among patients. In conclusion, since psoriasis is a common disease, its link between TIO needs further research studies and investigations to prove if it is actually true or just a mere coincidence.
