There may be a reduced but moderate number of cells and ducts enveloped in fibrous sheaths, as well as fibrous proliferation of the glands septa. The cytologic findings by themselves may not be specific, and the diagnosis requires adjunct consideration of both the ultrasonogram and clinical presentation. Application of magnetic resonance imaging (MRI) has been tried to non-invasively examine the morphological variations in Küttners tumor and differentiate them from those seen in malignant tumors; while MRI findings of the affected tissue and the pattern of cellular infiltration may offer some diagnostic clues for this condition, so far the results have been inconclusive. Existing treatment
Standard, and most effective, therapy to date is glandular sialadenectomy, which is associated with fairly low operative morbidity; however, in recent times, the administration of steroid (which can shrink the inflammatory lesion and is known to reduce serum IgG4 values) has been considered favorably, and may be useful in younger patients or those who refuse surgery.

The transverse nasal crease or groove is a usually white line between the upper two-thirds and the lower third of the human nose (slightly above the cartilage tip between the bridge and nostrils). It can occur as the result of heredity, accident, or the constant rubbing or wiping of the nose, commonly referred to as the allergic salute. Occurrence
In addition to cases caused by heredity, physical injury, the transverse nasal crease is common in children and adults with chronic nasal allergies. People with allergies often use their hands to remove mucus from a runny nose or rub an itchy nose. As the hand slides upward, the tip of the nose is pressed up, thus creating the crease. Appearance
The appearance of the line depends on skin pigmentation. On lighter-skinned people, the transverse nasal crease is lighter in color than the surrounding skin, and may appear white. This is due to hypopigmentation resulting from the low level of melanin present in the damaged skin. In darker-skinned people, the line may appear darker than the surrounding skin. == References ==
