Oral PathologyPernicious anemia (vitamin B12 deficiency) is associated with neurological symptoms including peripheral neuropathy, subacute combined degeneration of the spinal cord, and demyelination. Premature graying of hair is also a characteristic feature due to B12s role in melanin synthesis. Folic acid deficiency causes megaloblastic anemia but not neurological symptoms. Plummer-Vinson and Paterson-Kelly syndromes are iron deficiency-related conditions without these specific manifestations.

Oral PathologyHemophilia A is primarily due to deficiency of Factor VIII, and Hemophilia B is due to Factor IX deficiency. These are inherited X-linked genetic disorders caused by mutations in the F8 or F9 genes respectively. Classical hemophilia is not due to autoimmune mechanisms, though acquired hemophilia (rare) can involve autoantibodies against Factor VIII. Prothrombin deficiency and Vitamin K deficiency cause different coagulation disorders.

Oral PathologyAuriculotemporal syndrome (Freys syndrome) consists of flushing, warmth, and perspiration over the cheek and pinna following ingestion of highly seasoned food. This occurs due to aberrant reinnervation of sweat glands by parasympathetic fibers that normally innervate the parotid gland, typically following parotid surgery or trauma. Fanonis, Horners, and Cushings syndromes do not involve this gustatory sweating phenomenon.
