The issue is most likely due to which decalcification problem?

• A. Overdecalcification
• B. Underdecalcification
• C. Inadequate dehydration
• D. Tissue tearing

Answer: (A)

Overdecalcification is the decalcification problem here. When decalcification goes too far or uses too strong an agent for too long, calcium is removed beyond what’s needed to cut the tissue cleanly. The mineral support that helps preserve tissue architecture becomes too depleted, leaving the specimen overly soft. On the slide, this shows up as a loss of fine nuclear and architectural detail, pale, diffuse staining, and potential distortion of the surrounding matrix. The tissue may also be prone to tearing during microtomy due to excessive softening. Underdecalcification would leave calcium to resist sectioning and produce different artifacts, while inadequate dehydration or tearing are processing issues not specific to decalcification.
