Do you have any knowledge of this rock's name? antiochturkey We need a little help here it is a white rock. The picture does not provide enough information. How hard is it (use Mohs scale of hardness). As fernwood said where is it from presumably Turkey (assumption based on you name) and is is sedimentary, metamorphic or Igneous do you know? How heavy is it compared to quartz for example? From just the image it could be Quartz, selenite, Gypsum, barite, calcite and probably several others so the above info may help to reduce the list. Anything beyond these common minerals may require a chemical test.

I'll throw one out there to ya, looks like a opal cross with agate or chalcedony? Like rmf mentions a little bit more info would help dearly.

That being said.... Reminds me of a replacement fossil, or trace fossil. Language barrier here, but what do you mean by psoriasis? Spots which could be cell structures? Other types of replacements I am familiar with include water, mud or silica. In rock formation in ancient times, water could fill the cavities of rocks. When a major event occurred, the water could transform to another element or mineral. Good example is the ancient coral nodule fossils I find on my land. The coral branches became filled with water after the death of the coral. The water later transformed into a clear or white quartz. Another example is that holes in other fossils (such as creatures, plants, trees or bones) or rocks became filled with water. This too transformed to many types of Quartz or other clear/white minerals. A lot depends on the ancient geology in the area.

I think something might be lost in translation with "psoriasis". Maybe they mean scaly?
