Learn About Tieche-Jadassohn Nevus

What is the definition of Tieche-Jadassohn Nevus?
Tièche-Jadassohn nevus are rare blue moles that have several different types. Blue moles are more common in women and Asians, and mostly occur in late childhood or adolescence. Common blue moles are benign and do not change over the course of a lifetime. However, in rare instances, cellular blue moles can become a form of malignant melanoma. Blue moles are caused by incomplete migration of melanocytes, while the blue color is caused by the Tyndall effect, where shorter wavelengths of incident light are scattered by melanocytes (melanin-forming cells). Blue moles are usually blue because their melanocytes are deeper than those of brown moles.
What are the symptoms of Tieche-Jadassohn Nevus?
Symptoms of the common blue mole are the appearance of a single blue or bluish, smooth surfaced, round or oval macule, papule, or plaque, usually found on hands or feet, buttocks, scalp, face, or below the nail. Rarely, blue moles can appear in the vagina, cervix, spermatic cord, lymph nodes, prostate, and mouth. Common blue moles are usually 0.5-to-1 cm in diameter. Cellular blue moles are at least 1 cm and more nodular. While usually blue, these moles can also be grey, brown, or yellow.

What are the current treatments for Tieche-Jadassohn Nevus?
Blue moles usually require no treatment; however, those on the scalp can be surgically removed as a preventative measure. Blue moles larger than 1 cm that change appearance or suddenly appear in older adults should be examined to rule out melanoma. Blue moles are also removed for cosmetic reasons.

After receiving my M.D. and Ph.D. at the University of Alabama at Birmingham, I came to the University of Michigan for residency training in Anatomic Pathology. During my residency and subsequent Dermatopathology fellowship, I became interested in mechanistic studies of cutaneous and soft-tissue malignancies. Upon completion of my fellowship in June 2012, I accepted a faculty position at UMHS with joint appointments in the Departments of Dermatology and Pathology, in which I continue to investigate molecular events in the pathogenesis of Merkel cell carcinoma and other cutaneous malignancies, while maintaining clinical effort in dermatopathology and molecular dermatopathology. Dr. Harms is rated as an Elite provider by MediFind in the treatment of Tieche-Jadassohn Nevus. He is also highly rated in 22 other conditions, according to our data. His clinical expertise encompasses Merkel Cell Carcinoma, Tieche-Jadassohn Nevus, Melanoma, and Sebaceous Adenoma. Dr. Harms is board certified in Pathology-Anatomic and Dermatopathology.
