it could be myelofibrosis, i meant mycosis fungoides, despite the name it isnt fungal. its the late stage symptom(the tumor looks like a fungus) a rare t-cell lymphoma, usually found in older aged white men(most of the time), it takes a long time(most of the time) to enter into a different stage.

MF looks eczema, allergy patches initially(but there are something unusual that usually is best discussed with a dermatologist)

Hope it isn't Glioblastoma. R.I.P. my dad.
