Granulomatous type Mitsuda reaction to leprosy Ag3. Contact dermatitis patch test4. Graft rejection chronic5. Jones - Mole reaction cutaneous basophil hypersensitivityType V stimulating type reaction: It is a modification of type II hypersensitivity reaction eg Graves disease - in which thyroid hormones are produced in excess amountThyroid stimulating antibody LATs is a specific thyroid auto antibody to thyroid membrane antigens, LATs can cross placenta which may lead to hyperthyroidism in neonates.Antibody - Dependent Cell Mediated Cytotoxicity ADCO Type VI hyper sensitivity reaction - While most workers prefer include the entity under immediate type Type I hypersensitivity reaction because of involvement of circulating Ig. ADCC is mediated through NK cells and the cytoplasmic mechanism is independent of compliment 206-C
