Pigmented lesions
Physiologic pigmentation
Etiology: it is due to increased pigmentation some pigmentation may be found in post menopausal women taking HRT or pregnancy
-
Characteristics: physiologic pigmented lesions do not blanch because they are due to melanin production and not to blood pooling within the tissues as a vascular pigmentation produces.
Dental implications: some patients complain about the cosmetic factors related to the pigmentation. The tongue and gingiva may be visible when speaking, and appearance may be troublesome
-
Amalgam tattoo
-
-
Characteristics: opaque fragments of metal are apparent in radiographs were amalgam tattoo is suspected and often confirmed the diagnosis
Dental implications: the calls of any pigmented area should be determined to rule out serious pathology such as melanoma
-
-
-
Blue nevus
Etiology: commonly referred to as a mole and in frequently seen orally. This is classified as benign but may appear similar to the early stage of melanoma
-
Characteristics: a distinguishing characteristic of the Nevis is pigmented color of the lesion when compared with normal mucosal skin tones. Additionally any nevus lesion may be elevated and should be recorded in three dimensional documentation
Dental implications: although the cutaneous Nevis is monitored and usually not removed and less suspicious the oral Nevis must be differentiated from a melanoma through removal and biopsy
Treatment and prognosis: biopsy is performed on the intro oral Nevis which is totally removed during the surgery. The area in question should be monitored and any subsequent areas should be biopsied as well
Oral melanotic macule
Etiology: A focal pigmented lesion that occurs on the lip or the intro oral tissues is referred to as an oral Melanotic macule when occurring on the web. Sun exposure is not an etiology
-
Characteristics: the Melanotic macules are usually brown, deep blue/black, or black, and they are well circumscribed with sharp delineated borders
Dental implications: when changes occur with these lesions, such as increased growth or shape, there could be a suspicion of a lesion that is characterized by early atypical melanocytes called Lentigo maligna
Treatment and prognosis: the prognosis for the oral melon otic macular is excellent, and they are followed and monitored after diagnosis through documentation and photographs
-
Oral melanoma
Etiology: malignant oral melanoma’s of the head and neck region are rare. Oral melanoma occurs in the oral tissues that are not exposed to the sun, and the ETIOLOGY is very different for oral melanomas and not as clearly understood
-
Characteristics: the intro oral melanoma may appear as a dark blue to black pigment area with no irregular borders increasing as the lesion continues to expand
Dental implications: the intro oral melanoma is a deadly lesion that should be recognized and removed in the early stage
Treatment and prognosis: oral melanoma is very aggressive with a much poor prognosis then melanomas found elsewhere in the body: therefore any pigmented lesion in the oral cavity should be viewed with suspicion
