Few blood in the urine (microscopic hematuria) is usually the sign of upper urinary tract infection (kidney)...... Yes some of the pics looks like Typical Ichthyosis?..having the sign of Ichthyosis for the first time after 40's is usually sign of systemic diseases...( more often SLE, Malignancy..etc...) so make sure to rule out every possibilities..talk to your doctor about it....Let's hope everything goes good with you... If you have a histopathology image u can send me... I could send it to few dermatopathologist for other suggestions...
